Rocket Hardware for Future Artemis Flights Moved to Barge for Delivery to Kennedy
NASA is making strides with the Artemis campaign as key components for the SLS (Space Launch System) rocket continue to make their way to NASA’s Kennedy Space Center. Teams with NASA and Boeing loaded the core stage boat-tail for Artemis III and the core stage engine section for Artemis IV onto the agency’s Pegasus barge at Michoud Assembly Facility on Aug. 28.
The core stage engine section of the SLS (Space Launch System) rocket for Artemis IV is loaded onto the agency’s Pegasus barge at Michoud Assembly Facility on Aug. 28. The core stage hardware will be moved Kennedy’s Space Systems Processing Facility for outfitting.NASA/Justin Robert The core stage hardware joins the launch vehicle stage adapter for Artemis II, which was moved onto the barge at NASA’s Marshall Space Flight Center on Aug. 21. Pegasus will ferry the multi-mission rocket hardware more than 900 miles to the Space Coast of Florida. Teams with the NASA’s Exploration Ground Systems Program will prepare the launch vehicle stage adapter for Artemis II stacking operations inside the Vehicle Assembly Building, while the core stage hardware will be moved to Kennedy’s Space Systems Processing Facility for outfitting. Beginning with Artemis III, core stages will undergo final assembly at Kennedy.
The launch vehicle stage adapter is essential for connecting the rocket’s core stage to the upper stage. It also shields sensitive avionics and electrical components in the rocket’s interim cryogenic propulsion stage from the intense vibrations and noise of launch.
The boat-tail and engine section are crucial for the rocket’s functionality. The boat-tail extends from the engine section, fitting snugly to protect the rocket’s engines during launch. The engine section itself houses more than 500 sensors, 18 miles of cables, and key systems for fuel management and engine control, all packed into the bottom of the towering 212-foot core stage.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

25 Years Strong: NASA’s Student Launch Competition Accepting 2025 Proposals
By Wayne Smith
NASA’s Student Launch competition kicks off its 25th year with the release of the 2025 handbook, detailing how teams can submit proposals by Sept. 11 for the event scheduled next spring near NASA’s Marshall Space Flight Center.
Student Launch is an annual competition challenging middle school, high school, and college students to design, build, test, and launch a high-powered amateur rocket with a scientific or engineering payload. After a team is selected, they must meet documentation milestones and undergo detailed reviews throughout the school year.
NASA’s Student Launch, a STEM competition, officially kicks off its 25th anniversary with the 2025 handbook.NASA Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2025 season, the payload challenge will again take inspiration from the Artemis missions, which seek to land the first woman and first person of color on the Moon.
As Student Launch celebrates its 25th anniversary, the payload challenge will include “reports” from STEMnauts, non-living objects representing astronauts. The 2024 challenge tasked teams with safely deploying a lander mid-air for a group of four STEMnauts using metrics to support a survivable landing. The lander had to be deployed without a parachute and had a minimum weight limit of five pounds.
“This year, we’re shifting the focus to communications for the payload challenge,” said John Eckhart, technical coordinator for Student Launch at Marshall. “The STEMnaut ‘crew’ must relay real-time data to the student team’s mission control. This helps connect Student Launch with the Artemis missions when NASA lands astronauts on the Moon.”
Thousands of students participated in the 2024 Student Launch competition – making up 70 teams representing 24 states and Puerto Rico. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission. The University of Notre Dame was the overall winner of the 2024 event, which culminated with a launch day open to the public.
Student Launch began in 2000 when former Marshall Director Art Stephenson started a student rocket competition at the center. It started with just two universities in Huntsville competing – Alabama A&M University and the University of Alabama in Huntsville – but has continued to soar. Since its inception, thousands of students have participated in the agency’s STEM competition, with many going on to a career with NASA.
“This remarkable journey, spanning a quarter of a century, has been a testament to the dedication, ingenuity, and passion of countless students, educators, and mentors who have contributed to the program’s success,” Eckhart said. “NASA Student Launch has been at the forefront of experiential education, providing students from middle school through university with unparalleled opportunities to engage in real-world engineering and scientific research. The program’s core mission – to inspire and cultivate the next generation of aerospace professionals and space explorers – has not only been met but exceeded in ways we could have only dreamed of.”
To encourage students to pursue degrees and careers in STEM (science, technology, engineering, and math), Marshall’s Office of STEM Engagement hosts Student Launch, providing them with real-world experiences. Student Launch is one of NASA’s nine Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of Artemis.
In addition to the NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.
“These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are the Artemis Generation, the future scientists, engineers, and innovators who will lead us into the future of space exploration.”

NASA Expands Human Exploration Rover Challenge to Middle Schools
By Wayne Smith
Following a 2024 competition that garnered international attention, NASA is expanding its Human Exploration Rover Challenge (HERC) to include a remote control division and inviting middle school students to participate.
The 31st annual competition is scheduled for April 11-12, 2025, at the U.S. Space & Rocket Center, near NASA’s Marshall Space Flight Center. HERC is managed by NASA’s Southeast Regional Office of STEM Engagement at Marshall. The HERC 2025 Handbook has been released, with guidelines for the new remote control (RC) division – ROVR (Remote-Operated Vehicular Research) – and detailing updates for the human-powered division.
The cover of the HERC 2025 handbook, which is now available online.NASA “Our RC division significantly lowers the barrier to entry for schools who don’t have access to manufacturing facilities, have less funding, or who are motivated to compete but don’t have the technical mentorship required to design and manufacture a safe human-powered rover,” said Chris Joren, HERC technical coordinator. “We are also opening up HERC to middle school students for the first time. The RC division is inherently safer and less physically intensive, so we invite middle school teams and organizations to submit a proposal to be a part of HERC 2025.”
Another change for 2025 is the removal of task sites on the course for the human-powered rover division, allowing teams to focus on their rover’s design. Recognized as NASA’s leading international student challenge, the 2025 challenge aims to put competitors in the mindset of the Artemis campaign as they pitch an engineering design for a lunar terrain vehicle – they are astronauts piloting a vehicle, exploring the lunar surface while overcoming various obstacles.
“The HERC team wanted to put together a challenge that allows students to gain 21st century skills, workforce readiness skills, and skills that are transferable,” said Vemitra Alexander, HERC activity lead. “The students have opportunities to learn and apply the engineering design process model, gain public speaking skills, participate in community outreach, and learn the art of collaborating with their peers. I am very excited about HERC’s growth and the impact it has on the students we serve nationally and internationally.”
Students interested in designing, developing, building, and testing rovers for Moon and Mars exploration are invited to submit their proposals to NASA through Sept. 19.
More than 1,000 students with 72 teams from around the world participated in the 2024 challenge as HERC celebrated its 30th anniversary as a NASA competition. Participating teams represented 42 colleges and universities and 30 high schools from 24 states, the District of Columbia, Puerto Rico, and 13 other nations from around the world.
“We saw a massive jump in recognition, not only from within the agency as NASA Chief Technologist A.C. Charania attended the event, but with several of our international teams meeting dignitaries and ambassadors from their home countries to cheer them on,” Joren said. “The most impressive thing will always be the dedication and resilience of the students and their mentors. No matter what gets thrown at these students, they still roll up to the start line singing songs and waving flags.”
HERC is one of NASA’s eight Artemis Student Challenges reflecting the goals of the Artemis campaign, which seeks to land the first woman and first person of color on the Moon while establishing a long-term presence for science and exploration. NASA uses such challenges to encourage students to pursue degrees and careers in the STEM fields of science, technology, engineering, and mathematics.
Since its inception in 1994, more than 15,000 students have participated in HERC – with many former students now working at NASA, or within the aerospace industry.

New NASA Sonifications Listen to the Universe’s Past
A quarter of a century ago, NASA released the “first light” images from the agency’s Chandra X-ray Observatory. This introduction to the world of Chandra’s high-resolution X-ray imaging capabilities included an unprecedented view of Cassiopeia A, the remains of an exploded star located about 11,000 light-years from Earth. Over the years, Chandra’s views of Cassiopeia A have become some of the telescope’s best-known images.
To mark the anniversary of this milestone, new sonifications of three images – including Cassiopeia A (Cas A) – are being released. Sonification is a process that translates astronomical data into sound, similar to how digital data are more routinely turned into images. This translation process preserves the science of the data from its original digital state but provides an alternative pathway to experiencing the data.
Sonifications of three images have been released to mark the 25th anniversary of Chandra’s “First Light” image. For Cassiopeia A, which was one of the first objects observed by Chandra, X-ray data from Chandra and infrared data from Webb have been translated into sounds, along with some Hubble data. The second image in the sonification trio, 30 Doradus, also contains Chandra and Webb data. NGC 6872 contains data from Chandra as well as an optical image from Hubble. Each of these datasets have been mapped to notes and sounds based on properties observed by these telescopes.NASA/CXC/SAO/K.Arcand, SYSTEM Sounds (M. Russo, A. Santaguida) This sonification of Cas A features data from Chandra as well as NASA’s James Webb, Hubble, and retired Spitzer space telescopes. The scan starts at the neutron star at the center of the remnant, marked by a triangle sound, and moves outward. Astronomers first saw this neutron star when Chandra’s inaugural observations were released 25 years ago this week. Chandra’s X-rays also reveal debris from the exploded star that is expanding outward into space. The brighter parts of the image are conveyed through louder volume and higher pitched sounds. X-ray data from Chandra are mapped to modified piano sounds, while infrared data from Webb and Spitzer, which detect warmed dust embedded in the hot gas, have been assigned to various string and brass instruments. Stars that Hubble detects are played with crotales, or small cymbals.
Another new sonification features the spectacular cosmic vista of 30 Doradus, one of the largest and brightest regions of star formation close to the Milky Way. This sonification again combines X-rays from Chandra with infrared data from Webb. As the scan moves from left to right across the image, the volume heard again corresponds to the brightness seen. Light toward the top of the image is mapped to higher pitched notes. X-rays from Chandra, which reveal gas that has been superheated by shock waves generated by the winds from massive stars, are heard as airy synthesizer sounds. Meanwhile, Webb’s infrared data show cooler gas that provides the raw ingredients for future stars. These data are mapped to a range of sounds including soft, low musical pitches (red regions), a wind-like sound (white regions), piano-like synthesizer notes indicating very bright stars, and a rain-stick sound for stars in a central cluster.
The final member of this new sonification triumvirate is NGC 6872, a large spiral galaxy that has two elongated arms stretching to the upper right and lower left, which is seen in an optical light view from Hubble. Just to the upper left of NGC 6872 appears another smaller spiral galaxy. These two galaxies, each of which likely has a supermassive black hole at the center, are being drawn toward one another. As the scan sweeps clockwise from 12 o’clock, the brightness controls the volume and light farther from the center of the image is mapped to higher-pitched notes. Chandra’s X-rays, represented in sound by a wind-like sound, show multimillion-degree gas that permeates the galaxies. Compact X-ray sources from background galaxies create bird-like chirps. In the Hubble data, the core of NGC 6872 is heard as a dark low drone, and the blue spiral arms (indicating active star formation) are audible as brighter, more highly pitched tones. The background galaxies are played as a soft pluck sound while the bright foreground star is accompanied by a crash cymbal.
More information about the NASA sonification project through Chandra, which is made in partnership with NASA’s Universe of Learning, can be found here. The collaboration was driven by visualization scientist Kimberly Arcand (CXC), astrophysicist Matt Russo, and musician Andrew Santaguida, (both of the SYSTEM Sounds project), along with consultant Christine Malec.
NASA’s Universe of Learning materials are based upon work supported by NASA under cooperative agreement award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and the Jet Propulsion Laboratory.
Chandra, managed for NASA by the agency’s Marshall Space Flight Center in partnership with the CXC, is one of NASA’s Great Observatories, along with the Hubble Space Telescope and the now-retired Spitzer Space Telescope and Compton Gamma Ray Observatory. It was first proposed to NASA in 1976 by Riccardo Giacconi, recipient of the 2002 Nobel Prize for Physics based on his contributions to X-ray astronomy, and Harvey Tananbaum, who would later become the first director of the Chandra X-ray Center. Chandra was named in honor of the late Nobel laureate Subrahmanyan Chandrasekhar, who earned the Nobel Prize in Physics in 1983 for his work explaining the structure and evolution of stars.

Europa Clipper Gets Set of Super-Size Solar Arrays
NASA’s Europa Clipper spacecraft recently got outfitted with a set of enormous solar arrays at the agency’s Kennedy Space Center. Each measuring about 46½ feet long and about 13½ feet high, the arrays are the biggest NASA has ever developed for a planetary mission. They must be large so they can soak up as much sunlight as possible during the spacecraft’s investigation of Jupiter’s moon Europa, which is five times farther from the Sun than Earth is.
NASA’s Europa Clipper is seen Aug. 21 at the agency’s Kennedy Space Center. Engineers and technicians deployed and tested the giant solar arrays to be sure they will operate in flight.NASA/Frank Michaux The arrays have been folded up and secured against the spacecraft’s main body for launch, but when they’re deployed in space, Europa Clipper will span more than 100 feet – a few feet longer than a professional basketball court. The “wings,” as the engineers call them, are so big that they could only be opened one at a time in the clean room of Kennedy’s Payload Hazardous Servicing Facility, where teams are readying the spacecraft for its launch period, which opens Oct. 10.
Meanwhile, engineers continue to assess tests conducted on the radiation hardiness of transistors on the spacecraft. Longevity is key, because the spacecraft will journey more than five years to arrive at the Jupiter system in 2030. As it orbits the gas giant, the probe will fly by Europa multiple times, using a suite of science instruments to find out whether the ocean underneath its ice shell has conditions that could support life.
Powering those flybys in a region of the solar system that receives only 3% to 4% of the sunlight Earth gets, each solar array is composed of five panels. Designed and built at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Airbus in Leiden, Netherlands, they are much more sensitive than the type of solar arrays used on homes, and the highly efficient spacecraft will make the most of the power they generate.
NASA’s Europa Clipper is seen in a clean room at Kennedy Space Center after engineers and technicians tested and stowed the spacecraft’s giant solar arrays.NASA/Frank Michaux At Jupiter, Europa Clipper’s arrays will together provide roughly 700 watts of electricity, about what a small microwave oven or a coffee maker needs to operate. On the spacecraft, batteries will store the power to run all of the electronics, a full payload of science instruments, communications equipment, the computer, and an entire propulsion system that includes 24 engines.
While doing all of that, the arrays must operate in extreme cold. The hardware’s temperature will plunge to minus 400 degrees Fahrenheit when in Jupiter’s shadow. To ensure that the panels can operate in those extremes, engineers tested them in a specialized cryogenic chamber at Liège Space Center in Belgium.
“The spacecraft is cozy. It has heaters and an active thermal loop, which keep it in a much more normal temperature range,” said APL’s Taejoo Lee, the solar array product delivery manager. “But the solar arrays are exposed to the vacuum of space without any heaters. They’re completely passive, so whatever the environment is, those are the temperatures they get.”
About 90 minutes after launch, the arrays will unfurl from their folded position over the course of about 40 minutes. About two weeks later, six antennas affixed to the arrays will also deploy to their full size. The antennas belong to the radar instrument, which will search for water within and beneath the moon’s thick ice shell, and they are enormous, unfolding to a length of 57.7 feet, perpendicular to the arrays.
“At the beginning of the project, we really thought it would be nearly impossible to develop a solar array strong enough to hold these gigantic antennas,” Lee said. “It was difficult, but the team brought a lot of creativity to the challenge, and we figured it out.”
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with APL for NASA’s Science Mission Directorate. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

Work is Underway on NASA’s Next-Generation Asteroid Hunter
NASA’s new asteroid-hunting spacecraft is taking shape at NASA’s Jet Propulsion Laboratory. Called NEO Surveyor (Near-Earth Object Surveyor), this cutting-edge infrared space telescope will seek out the hardest-to-find asteroids and comets that might pose a hazard to our planet. In fact, it is the agency’s first space telescope designed specifically for planetary defense.
Targeting launch in late 2027, the spacecraft will travel a million miles to a region of gravitational stability – called the L1 Lagrange point – between Earth and the Sun. From there, its large sunshade will block the glare and heat of sunlight, allowing the mission to discover and track near-Earth objects as they approach Earth from the direction of the Sun, which is difficult for other observatories to do. The space telescope also may reveal asteroids called Earth Trojans, which lead and trail our planet’s orbit and are difficult to see from the ground or from Earth orbit.
A mirror that was later installed inside NASA’s Near-Earth Object Surveyor shows a reflection of principal optical engineer Brian Monacelli during an inspection of the mirror’s surface at the agency’s Jet Propulsion Laboratory on July 17.NASA/JPL-Caltech NEO Surveyor relies on cutting-edge detectors that observe two bands of infrared light, which is invisible to the human eye. Near-Earth objects, no matter how dark, glow brightly in infrared as the Sun heats them. Because of this, the telescope will be able to find dark asteroids and comets, which don’t reflect much visible light. It also will measure those objects, a challenging task for visible-light telescopes that have a hard time distinguishing between small, highly reflective objects and large, dark ones.
“NEO Surveyor is optimized to help us to do one specific thing: enable humanity to find the most hazardous asteroids and comets far enough in advance so we can do something about them,” said Amy Mainzer, survey director for NEO Surveyor and a professor at the University of California, Los Angeles. “We aim to build a spacecraft that can find, track, and characterize the objects with the greatest chance of hitting Earth. In the process, we will learn a lot about their origins and evolution.”
The spacecraft’s only instrument is its telescope. About the size of a washer-and-dryer set, the telescope’s blocky aluminum body, called the optical bench, was built in a JPL clean room. Known as a three-mirror anastigmat telescope, it will rely on curved mirrors to focus light onto its infrared detectors in such a way that minimizes optical aberrations.
“We have been carefully managing the fabrication of the spacecraft’s telescope mirrors, all of which were received in the JPL clean room by July,” said Brian Monacelli, principal optical engineer at JPL. “Its mirrors were shaped and polished from solid aluminum using a diamond-turning machine. Each exceeds the mission’s performance requirements.”
Monacelli inspected the mirror surfaces for debris and damage, then JPL’s team of optomechanical technicians and engineers attached the mirrors to the telescope’s optical bench in August. Next, they will measure the telescope’s performance and align its mirrors.
Complementing the mirror assembly are the telescope’s mercury-cadmium-telluride detectors, which are similar to the detectors used by NASA’s recently retired NEOWISE (short for Near-Earth Object Wide-field Infrared Survey Explorer) mission. An advantage of these detectors is that they don’t necessarily require cryogenic coolers or cryogens to lower their operational temperatures in order to detect infrared wavelengths. Cryocoolers and cryogens can limit the lifespan of a spacecraft. NEO Surveyor will instead keep its cool by using its large sunshade to block sunlight from heating the telescope and by occupying an orbit beyond that of the Moon, minimizing heating from Earth.
A technician operates articulating equipment to rotate NEO Surveyor’s aluminum optical bench – part of the spacecraft’s telescope – in a clean room at NASA’s Jet Propulsion Laboratory.NASA/JPL-Caltech The telescope will eventually be installed inside the spacecraft’s instrument enclosure, which is being assembled in JPL’s historic High Bay 1 clean room where NASA missions such as Voyager, Cassini, and Perseverance were constructed. Fabricated from dark composite material that allows heat to escape, the enclosure will help keep the telescope cool and prevent its own heat from obscuring observations.
Once it is completed in coming weeks, the enclosure will be tested to make sure it can withstand the rigors of space exploration. Then it will be mounted on the back of the sunshade and atop the electronic systems that will power and control the spacecraft.
“The entire team has been working hard for a long time to get to this point, and we are excited to see the hardware coming together with contributions from our institutional and industrial collaborators from across the country,” said Tom Hoffman, NEO Surveyor’s project manager at JPL. “From the panels and cables for the instrument enclosure to the detectors and mirrors for the telescope — as well as components to build the spacecraft — hardware is being fabricated, delivered, and assembled to build this incredible observatory.”
Assembly of NEO Surveyor can be viewed 24 hours a day, seven days a week, via JPL’s live cam.
The NEO Surveyor mission marks a major step for NASA toward reaching its U.S. Congress-mandated goal to discover and characterize at least 90% of the near-Earth objects more than 460 feet across that come within 30 million miles of our planet’s orbit. Objects of this size can cause significant regional damage, or worse, should they impact the Earth.
The mission is tasked by NASA’s Planetary Science Division within the Science Mission Directorate; program oversight is provided by the Planetary Defense Coordination Office, which was established in 2016 to manage the agency’s ongoing efforts in planetary defense. NASA’s Planetary Missions Program Office at the agency’s Marshall Space Flight Center provides program management for NEO Surveyor.
The project is being developed by JPL and is led by survey director Amy Mainzer at UCLA. Established aerospace and engineering companies have been contracted to build the spacecraft and its instrumentation, including BAE Systems, Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder will support operations, and IPAC-Caltech in Pasadena, California, is responsible for processing survey data and producing the mission’s data products. Caltech manages JPL for NASA.

Technicians test a set of massive solar arrays measuring about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high for NASA’s Europa Clipper spacecraft inside the agency’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Aug. 7.Credits: NASA/Kim Shiflett NASA and SpaceX are targeting a launch period opening Thursday, Oct. 10, for the agency’s Europa Clipper mission, which will help scientists determine if one of Jupiter’s icy moons could support life. The mission will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Europa Clipper will carry nine instruments and a gravity science experiment aboard to gather detailed measurements as it orbits Jupiter and conducts multiple close flybys of its moon, Europa. Research suggests an ocean twice the volume of all of Earth’s oceans exists under Europa’s icy crust.

Marshall Leadership Updates Team Members on Culture, Strategy
By Wayne Smith
Leadership from NASA’s Marshall Space Flight Center highlighted a successful summer before looking ahead to the center’s culture and strategy during an all-hands meeting Aug. 27 in Building 4316.
Marshall Director Joseph Pelfrey recapped milestone events of the past few months, including new hardware for the Artemis II test flight. The launch vehicle stage adapter for the SLS (Space Launch System) rocket was rolled out Aug. 21 at Marshall and loaded on to the Pegasus barge. In July, the rocket’s core stage was shipped from NASA’s Michoud Assembly Facility to the agency’s Kenney Space Center. The summer started with a NASA in the Park event in downtown Huntsville that attracted more than 14,000 people to learn more about Marshall’s work and is winding down with the continued celebration of the 25th anniversary of NASA’s Chandra X-ray Observatory.
NASA Marshall Space Flight Center Director Joseph Pelfrey, left, speaks to team members during the all-hands meeting Aug. 26 in Building 4316. Joining Pelfrey on stage, from left, are Rae Ann Meyer, deputy director; Roger Baird, associate director; and Larry Leopard, associate director, technical. NASA/Krisdon Manecke Pelfrey also commended Marshall’s Commercial Crew Program team members for their dedicated work and support of NASA’s Boeing Starliner Crew Flight Test to the International Space Station.
“I just really appreciate the teams that worked so hard between NASA and Boeing to evaluate issues, and the ultimate decision was about safety,” Pelfrey said. “Those teams did a lot of tremendous work on analysis and testing to bring data to decision makers. Now we will get to move forward.”
Before discussing Marshall’s culture and strategy, Pelfrey introduced three new members of Marshall’s leadership team: Davey Jones, center strategy lead; Denise Smithers, center executive officer; and Roger Baird, associate director.
Pelfrey said leadership recognizes the vital roles culture and strategy play in the center’s ongoing success as Marshall makes a transformative shift to more strategic partnerships across NASA and with industry. He pointed to activities like NASA 2040 and More to Marshall as the center heads toward its 65th anniversary next summer.
“Embracing a supportive work culture enhances collaboration, improves communication, and builds a sense of belonging and purpose,” Pelfrey said. “The center’s leadership team wants culture to come from all of us, so we continue to create opportunities for you to get involved, hear your feedback, and help shape the culture at Marshall.”
Rae Ann Meyer, the center’s deputy director, provided updates on Marshall’s culture initiatives. She invited team members to participate in a survey on the most important attributes for a thriving center, following up on feedback from last August. Meyer said leadership wants continued input from team members and applauded Marshall’s highest ever participation (85.1%) in the 2024 Federal Employee Viewpoint Survey.
Marshall team members listen as Meyer, on stage at left, talks about the center’s culture initiatives.NASA/Krisdon Manecke “Regardless of role, each team member plays a vital part in shaping the culture that makes NASA and Marshall an extraordinary place to work and achieve great things,” Meyer said. “Creating a positive culture is a long-term process that requires time and sustained effort – it does not happen overnight.”
In his remarks, Jones also encouraged feedback and participation from team members. He said center culture and strategy “need to be attached at the hip.”
“Part of that success is making sure communication is open between center strategy and culture and to the workforce because it not only encourages collaboration, but also fosters transparency, which is one of the key cultural attributes discussed today,” Jones said.
Leadership took questions from team members to close out the session, before wrapping up with a More to Marshall video.
“This year, you have heard a lot about More to Marshall, and it is more than a slogan; it really symbolizes the initiative we have to prepare our center for the future and take advantage of all the expertise we have at the center and all our capabilities,” Pelfrey said. “It’s an approach that reinforces our center strategy that’s going to enable our future role in space exploration.”

NASA Moves Artemis II Rocket Adapter to Pegasus Barge for Shipment
NASA rolled out a key piece of space flight hardware for the SLS (Space Launch System) rocket for the first crewed mission of NASA’s Artemis campaign from Marshall Space Flight Center on Aug. 21 for shipment to the agency’s Kennedy Space Center. The cone-shaped launch vehicle stage adapter connects the rocket’s core stage to the upper stage and helps protect the upper stage’s engine that will help propel the Artemis II test flight around the Moon, slated for 2025.
Crews moved the cone-shaped launch vehicle stage adapter out of Building 4708 at NASA’s Marshall Space Flight Center to the agency’s Pegasus barge on Aug. 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility, where it will pick up additional SLS hardware for future Artemis missions, and then travel to the agency’s Kennedy Space Center. In Florida, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.NASA/Brandon Hancock “The launch vehicle stage adapter is the largest SLS component for Artemis II that is made at the center,” said Chris Calfee, SLS Spacecraft Payload Integration and Evolution element manager. “Both the adapters for the SLS rocket that will power the Artemis II and Artemis III missions are fully produced at NASA Marshall. Alabama plays a key role in returning astronauts to the Moon.”

Cassiopeia A,Thenthe Cosmos: 25 Years of Chandra X-ray Science
By Rick Smith
On Aug. 26, 1999, NASA’s Chandra X-ray Observatory opened its powerful telescopic eye in orbit and captured its awe-inspiring “first light” images of Cassiopeia A, a supernova remnant roughly 11,000 light-years from Earth. That first observation was far more detailed than anything seen by previous X-ray telescopes, even revealing – for the first time ever – a neutron star left in the wake of the colossal stellar detonation.
NASA’s Chandra X-ray Observatory has observed Cassiopeia A for more than 2 million total seconds since its “first light” images of the supernova remnant on Aug. 26, 1999. Cas A is some 11,000 light-years from Earth. Chandra X-rays are depicted in blue and composited with infrared images from NASA’s James Webb Space Telescope in orange and white.X-ray: NASA/CXC/SAO; Infrared: NASA/ESA/CSA/STScI/D. Milisavljevic (Purdue Univ.), I. De Looze (University of Ghent), T. Temim (Princeton Univ.); Image Processing: NASA/CXC/SAO/J. Schmidt, K. Arcand, and J. Major Those revelations came as no surprise to Chandra project scientist Martin Weisskopf, who led Chandra’s development at NASA’s Marshall Space Flight Center. “When you build instrumentation that’s 10 times more sensitive than anything that was done before, you’re bound to discover something new and exciting,” he said. “Every step forward was a giant step forward.”
Twenty-five years later, Chandra has repeated that seminal moment of discovery again and again, delivering – to date – nearly 25,000 detailed observations of neutron stars, quasars, supernova remnants, black holes, galaxy clusters, and other highly energetic objects and events, some as far away as 13 billion light-years from Earth.
Chandra has further helped scientists gain tangible evidence of dark matter and dark energy, documented the first electromagnetic events tied to gravitational waves in space, and most recently aided the search for habitable exoplanets – all vital tools for understanding the vast, interrelated mechanisms of the universe we live in.
“Chandra’s first image of Cas A provided stunning demonstration of Chandra’s exquisite X-ray mirrors, but it simultaneously revealed things we had not known about young supernova remnants,” said Pat Slane, director of the CXC (Chandra X-ray Center) housed at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. “In a blink, Chandra not only revealed the neutron star in Cas A; it also taught us that young neutron stars can be significantly more modest in their output than what previously had been understood. Throughout its 25 years in space, Chandra has deepened our understanding of fundamental astrophysics, while also greatly broadening our view of the universe.”
To mark Chandra’s silver anniversary, NASA and CXC have shared 25 of its most breathtaking images and debuted a new video, “Eye on the Cosmos.”
Chandra often is used in conjunction with other space telescopes that observe the cosmos in different parts of the electromagnetic spectrum, and with other high-energy missions such as ESA’s (European Space Agency’s) XMM-Newton; NASA’s Swift, NuSTAR (Nuclear Spectroscopic Telescope Array), and IXPE (Imaging X-ray Polarization Explorer) imagers, and NASA’s NICER (Neutron Star Interior Composition Explorer) X-ray observatory, which studies high-energy phenomena from its vantage point aboard the International Space Station.
These images were released to commemorate the 25th anniversary of Chandra. They represent the wide range of objects that the telescope has observed over its quarter century of observations. X-rays are an especially penetrating type of light that reveals extremely hot objects and very energetic physical processes. The images range from supernova remnants, like Cassiopeia A, to star-formation regions like the Orion Nebula, to the region at the center of the Milky Way. This montage also contains objects beyond our own Galaxy including other galaxies and galaxy clusters.X-ray: NASA/CXC/UMass/Q.D. Wang; Image processing: NASA/CXC/SAO/N. Wolk Chandra remains a unique, global science resource, with a robust data archive that will continue to serve the science community for many years.
“NASA’s project science team has always strived to conduct Chandra science as equitably as possible by having the world science community collectively decide how best to use the observatory’s many tremendous capabilities,” said Douglas Swartz, a USRA (Universities Space Research Association) principal research scientist on the Chandra project science team.
“Chandra will continue to serve the astrophysics community long after its mission ends,” said Andrew Schnell, acting Chandra program manager at Marshall. “Perhaps its greatest discovery hasn’t been discovered yet. It’s just sitting there in our data archive, waiting for someone to ask the right question and use the data to answer it. It could be somebody who hasn’t even been born yet.”
That archive is impressive indeed. To date, Chandra has delivered more than 70 trillion bytes of raw data. More than 5,000 unique principal investigators and some 3,500 undergraduate and graduate students around the world have conducted research based on Chandra’s observations. Its findings have helped earn more than 700 PhDs and resulted in more than 11,000 published papers, with half a million total citations.
NASA’s Chandra X-ray Observatory data, seen here in violet and white, is joined with that of NASA’s Hubble Space Telescope (red, green, and blue) and Imaging X-ray Polarimetry Explorer (purple) to show off the eerie beauty of the Crab Nebula. The nebula is the result of a bright supernova explosion first witnessed and documented in 1054 A.D.X-ray: (Chandra) NASA/CXC/SAO, (IXPE) NASA/MSFC; Optical: NASA/ESA/STScI; Image Processing: NASA/CXC/SAO/J. Schmidt, K. Arcand, and L. Frattare Weisskopf is now an emeritus researcher who still keeps office hours every weekday despite having retired from NASA in 2022. He said the work remains as stimulating now as it was 25 years ago, waiting breathlessly for those “first light” images.
“We’re always trying to put ourselves out of business with the next bit of scientific understanding,” he said. “But these amazing discoveries have demonstrated how much NASA’s astrophysics missions still have to teach us.”
The universe keeps turning – and Chandra’s watchful eye endures.
Chandra, managed for NASA by Marshall in partnership with the CXC, is one of NASA’s Great Observatories, along with the Hubble Space Telescope and the now-retired Spitzer Space Telescope and Compton Gamma Ray Observatory. It was first proposed to NASA in 1976 by Riccardo Giacconi, recipient of the 2002 Nobel Prize for Physics based on his contributions to X-ray astronomy, and Harvey Tananbaum, who would later become the first director of the Chandra X-ray Center. Chandra was named in honor of the late Nobel laureate Subrahmanyan Chandrasekhar, who earned the Nobel Prize in Physics in 1983 for his work explaining the structure and evolution of stars.

Take 5 with April Hargrave
By Wayne Smith
April Hargrave’s father was an educator who encouraged her from an early age to believe she could be whatever she wanted to be.
She followed her father’s guidance.
April Hargrave is the manager of Program, Planning, and Control (PP&C) in the Human Exploration Development and Operations (HP/HEDO) Office at NASA’s Marshall Space Flight Center.Photo courtesy of Jenna Hassell Today, Hargrave is the manager of Program, Planning, and Control (PP&C) in the Human Exploration Development and Operations (HP/HEDO) Office at NASA’s Marshall Space Flight Center. Hargrave credits her parents for inspiring her to seek a career that eventually led to Marshall, where she has been for 15 years.
Hargrave’s father – G.W. Braidfoot – was a high school educator in Lawrence County, Alabama, for 28 years. He taught history and civics, before moving into roles as an administrator and guidance counselor, focusing on guiding his students toward their post-high school goals.
“What has always stood out to me is my parents never placed boundaries on my passions and career choices,” said Hargrave, a North Alabama native who lives in Athens. “Reflecting back, that is something of which I am very appreciative. In the absence of boundaries, it has allowed me to push myself in my pursuits and shaped my career path, which included high school STEM courses and college career choices.
Those college choices were pursuing a bachelor’s degree in chemistry at the University of North Alabama in Florence, and later another degree in chemical engineering at the University of Alabama in Huntsville.
As PP&C manager for HEDO’s diverse and complex portfolio of programs, projects, and other activities, Hargrave provides tools and resources to HP management that enables strategic decision making and workforce planning.
“My background and experiences helped shaped my early career in industry and established a strong foundation and relationships, which led me to Marshall mid-career,” she said. “At Marshall, I’m thankful to have had mentors and encouragers who have led me to my current leadership role – people who believed in me and allowed me an opportunity. For that, I will forever be grateful.”
Question: What excites you most about the future of human space exploration, or your NASA work, and your team’s role it?
Hargrave: What excites me the most are the advancements we are making in human health and exploration. I’ve had close relatives suffer from diseases, such as Alzheimer’s and heart disease. I hope to see in the near future outcomes of human research on the International Space Station and the Moon that leads to medical and technology advancements, resulting in slowing the progression and eventually eliminating these diseases. Our HP PP&C team enables our missions by providing planning, integration, and support across our organization.
Question: What has been the proudest moment of your career and why?
Hargrave: Being able to mentor others throughout my career and watching them achieve success. Being in a position to recognize potential in others and encourage them to stretch and take risks in their careers, I find it very rewarding, especially after they have moved on that I’m able to still observe the growth and development they’ve experienced and to know I made a contribution.
Question: Who or what drives/motivates you?
Hargrave: My team drives me – I have a wonderful team that motivates me to be the best version of myself I can be. My team is comprised of a diverse group of personnel whose jobs are not always connected. However, we are still able to promote a great teaming environment where we encourage and leverage off each other’s skills and knowledge bases. My team is dedicated to doing the best job possible which motivates me daily in the excellent support they provide across HP. It allows me opportunities to lead by example and recognize their successes. It also allows me to look across the team and how to use them best based on their strengths.
Question: What advice do you have for employees early in their NASA career or those in new leadership roles?
Hargrave: It is important to learn what the NASA mission is and don’t be afraid to ask questions. Learn about the work that you are doing and how it impacts the mission as a whole. As you learn and understand the work within your role, develop a passion for the work. Take opportunities to understand the big picture and learn what others are doing across the center. Don’t be afraid to take lateral opportunities to allow you to gain new experiences and broaden your knowledge base. And if you find yourself in a leadership role, never lose sight that it’s the people behind that work that’s most important. Take the time to build and nurture those relationships because at the end of the day, our workforce is what makes us successful.
Question: What do you enjoy doing with your time while away from work?
Hargrave: My joy is helping and supporting others. Being part of a large family (raised one of five children and an even larger extended family), there’s naturally always plenty to do and lots of family to help and encourage. Much of my recent years have been spent cheering on my sons, nieces, and nephews. I also enjoy serving in my church and helping organize events to celebrate our family and friends.

Over the Moon: Photographer Captures Supermoon Rising Near Marshall
By Wayne Smith
Once in a Blue Moon wasn’t enough for Michael DeMocker, a photographer for NASA’s Michoud Assembly Facility.
Nearly one year after capturing a spectacular image of a super Blue Moon rising over the Crescent City Connection Bridge in New Orleans, DeMocker found another opportunity to focus his camera on the lunar landscape while visiting the Rocket City. The result was another stunning photograph, this one of the Moon rising Aug. 19 behind the Saturn V rocket at the U.S. Space & Rocket Center in Huntsville, near NASA’s Marshall Space Flight Center
A super Blue Moon rises Aug. 19 over Huntsville, home to NASA’s Marshall Space Flight Center and the U.S. Space and Rocket Center. The full Moon was both a supermoon and a Blue Moon. As the Moon reaches its closest approach to Earth, the Moon looks larger in the night sky with supermoons becoming the biggest and brightest full Moons of the year. While not blue in color, the third full Moon in a season with four full Moons is called a Blue Moon.NASA/Michael DeMocker And you can say the image DeMocker captured left him, well, over the Moon. He explains how he got the photo.
“NASA photographer Eric Bordelon and I drove up from Michoud to Marshall to provide drone support for the move of the launch vehicle stage adapter of the SLS (Space Launch System) rocket to NASA’s Pegasus barge on Aug. 21,” DeMocker said. “On the trip up, we talked about possibly capturing the super Blue Moon rising that night. Using an app that shows the direction of the moonrise overlayed with a satellite image of the area, we couldn’t find a definitive spot where we thought we could get a clean line of the Moon rising with some kind of iconic Huntsville landmark. So, like good New Orleanians, we put off thinking about it until after eating. As we approached the restaurant, we caught glimpses of the Saturn V rocket at the U.S. Space & Rocket Center. We realized if we got on the roof of a nearby parking garage, we would have a clean view of the Moon rising somewhat behind it.
“The angle wasn’t perfect; I’d have preferred to be more to the right but that would have sent me plummeting off the parking garage. The clouds cooperated, the Moon rose bright and beautiful, and I got images I was happy with while Eric got a very cool time-lapse video of the Moon and the rocket.”
So, of the two Blue Moon images, which is DeMocker’s favorite?
“Yikes, that’s like choosing a child!” DeMocker said. “My favorite pictures are not always the best ones, but the ones that I didn’t think I would be able to pull off. So, while the Moon over the bridge I think is an overall better photo, it was pretty easy to plan and didn’t require much resourcefulness, so I like the rocket one better.”
DeMocker, a past Pulitzer Prize winner for team coverage of Hurricane Katrina, was honored this year with third-place finishes in two categories in NASA’s Photographer of the Year competition. He also was part of a Michoud team that captured a first-place award in the agency’s Videographer of the Year competition.
“But my favorite photos I’ve ever shot in my career have never won awards,” DeMocker said. “I like them because I thought they would be almost impossible to get when I set out after them: a drone shot of an erupting volcano in Iceland, an Iraqi woman voting in Baghdad, or my toddler quietly looking at art in the Louvre.”

NASA, Boeing Optimizing Vehicle Assembly Building High Bay for Future SLS Stage Production
NASA is preparing space at the agency’s Kennedy Space Center for upcoming assembly activities of the SLS (Space Launch System) rocket core stage for future Artemis missions, beginning with Artemis III.
Teams are currently outfitting the assembly building’s High Bay 2 for future vertical assembly of the rocket stage that will help power NASA’s Artemis campaign to the Moon. During Apollo, High Bay 2, one of four high bays inside the Vehicle Assembly Building, was used to stack the Saturn V rocket. During the Space Shuttle Program, the high bay was used for external tank checkout and storage and as a contingency storage area for the shuttle.
Technicians are building tooling in High Bay 2 at NASA Kennedy that will allow NASA and Boeing, the SLS core stage lead contractor, to vertically integrate the core stage.NASA Michigan-based Futuramic is constructing the tooling that will hold the core stage in a vertical position, allowing NASA and Boeing, the SLS core stage lead contractor, to integrate the SLS rocket’s engine section and four RS-25 engines to finish assembly of the rocket stage. Vertical integration will streamline final production efforts, offering technicians 360-degree access to the stage both internally and externally.
“The High Bay 2 area at NASA Kennedy is critical for work as SLS transitions from a developmental to operational model,” said Chad Bryant, deputy manager of the SLS Stages Office. “While teams are stacking and preparing the SLS rocket for launch of one Artemis mission, the SLS core stage for another Artemis mission will be taking shape just across the aisleway.”
Under the new assembly model beginning with Artemis III, all the major structures for the SLS core stage will continue to be fully produced and manufactured at NASA’s Michoud Assembly Facility. Upon completion of manufacturing and thermal protection system application, the engine section will be shipped to NASA Kennedy for final outfitting. Later, the top sections of the core stage – the forward skirt, intertank, liquid oxygen tank, and liquid hydrogen tank – will be outfitted and joined at Michoud and shipped to Kennedy for final assembly.
The fully assembled core stage for Artemis II arrived at Kennedy on July 23. NASA’s Pegasus barge delivered the SLS engine section for Artemis III to Kennedy in December 2022. Teams at Michoud are outfitting the remaining core stage elements and preparing to horizontally join them. The four RS-25 engines for the Artemis III mission are complete at NASA’s Stennis Space Center and will be transported to Kennedy in 2025. Major core stage and exploration upper stage structures are in work at Michoud for Artemis IV and beyond.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

How Students Learn to Fly NASA’s IXPE Spacecraft
The large wall monitor displaying a countdown shows 17 seconds when Amelia “Mia” De Herrera-Schnering tells her teammates “We have AOS,” meaning “acquisition of signal.”
“Copy that, thank you,” Alexander Pichler replies. The two are now in contact with NASA’s IXPE (Imaging X-Ray Polarimeter Explorer) spacecraft, transmitting science data from IXPE to a ground station and making sure the download goes smoothly. That data will then go to the science team for further analysis.
Amelia “Mia” De Herrera-Schnering is an undergraduate student at the University of Colorado, Boulder, and command controller for NASA’s IXPE mission at the Laboratory for Atmospheric and Space Physics (LASP). NASA/Elizabeth Landau At LASP, the Laboratory for Atmospheric and Space Physics, students at the University of Colorado, Boulder, can train to become command controllers, working directly with spacecraft on pointing the satellites, calibrating instruments, and collecting data. De Herrera-Schnering recently completed her sophomore year, while Pichler had trained as a student and now, having graduated, works as a full-time professional at LASP.
“The students are a key part in what we do,” said Stephanie Ruswick, IXPE flight director at LASP. “We professionals monitor the health and safety of the spacecraft, but so do the students, and they do a lot of analysis for us.”
Students also put into motion IXPE’s instrument activity plans, which are provided by the Science Operations Center at NASA’s Marshall Space Flight Center. The LASP student team schedules contacts with ground stations to downlink data, schedules observations of scientific and calibration targets, and generates the files necessary to translate the scientific operations into spacecraft actions. If IXPE experiences an anomaly, the LASP team will implement plans to remediate and resume normal operations as soon as possible.
The students take part in IXPE’s exploration of a wide variety of celestial targets. In October, for example, students monitored the transmission of data from IXPE’s observations of Swift J1727.8-1613, a bright black hole X-ray binary system. This cosmic object had been recently discovered in September 2023, when NASA’s Neil Gehrels Swift Observatory detected a gamma-ray burst. IXPE’s specialized instruments allow scientists to measure the polarization of X-rays, which contains information about the source of the X-rays as well as the organization of surrounding magnetic fields. IXPE’s follow-up of the Swift object exemplifies how multiple space missions often combine their individual strengths to paint a fuller scientific picture of distant phenomena.
Team members also conduct individual projects. For example, students analyzed how IXPE would fare during both the annular eclipse on Oct. 14, 2023, and the total eclipse that moved across North America on April 8, to make sure that the spacecraft would have adequate power while the Moon partially blocked the Sun.
Sam Lippincott, right, a graduate student lead at LASP, trained as a command controller for NASA’s IXPE spacecraft as an undergraduate. In the background are flight controllers Adrienne Pickerill, left, and Alexander Pichler, who also trained as students. NASA/Elizabeth Landau While most of the students working on IXPE at LASP are engineering majors, some are physics or astrophysics majors. Some didn’t initially start their careers in STEM such as flight controller Kacie Davis, who previously studied art.
Prospective command controllers go through a rigorous 12-week summer training program working 40 hours per week, learning “everything there is to know about mission operations and how to fly a spacecraft,” Ruswick said.
Cole Writer, an aerospace engineering student, remembers this training as “nerve-wracking” because he felt intimidated by the flight controllers. But after practicing procedures on his own laptop, he felt more confident, and completed the program to become a command controller.
“It’s nice to be trained by other students who are in the same boat as you and have gone through the same process,” said Adrienne Pickerill, a flight controller who started with the team as a student and earned a master’s in aerospace engineering at the university in May.
As a teenager Writer’s interests focused on flying planes, and he saved money to train for a pilot’s license, earning it the summer after high school graduation. Surprisingly, he has found many overlaps in skills for both activities – following checklists and preventing mistakes. “Definitely high stakes in both cases,” he said.
While working at LASP, the Laboratory for Atmospheric and Space Physics, students at the University of Colorado, Boulder, train to become command controllers who work and manage spacecraft. From monitoring IXPE’s health and safety to sending commands to the spacecraft to look at cosmic objects at the request of scientists, these students are getting a one-of-a-kind hands-on experience. (NASA) Sam Lippincott, now a graduate student lead after serving as a command controller as an undergraduate, has been a lifelong sci-fi fan, but took a career in space more seriously his sophomore year of college. “For people that want to go into the aerospace or space operations industry, it’s always important to remember that you’ll never stop learning, and it’s important to remain humble in your abilities, and always be excited to learn more,” he said.
De Herrera-Schnering got hooked on the idea of becoming a scientist the first time she saw the Milky Way. On a camping trip when she was 10 years old, she spotted the galaxy as she went to use the outhouse in the middle of the night. “I woke up my parents, and we just laid outside and we were just stargazing,” she said. “After that I knew I was set on what I wanted to do.”
Rithik Gangopadhyay, who trained as an undergraduate command controller and continued at LASP as a graduate student lead, had been interested in puzzles and problem-solving as a kid and had a book about planets that fascinated him. “There’s so much out there and so much we don’t know, and I think that’s what really pushed me to do aerospace and do this opportunity of being a command controller,” he said.
Coding is key to mission operations, and much of it is done in the Python language. Sometimes the work of flying a spacecraft feels like any other kind of programming — but occasionally, team members step back and consider that they are part of the grand mission of exploring the universe.
“If it’s your job for a couple of years, it starts to be like, ‘oh, let’s go ahead and do that, it’s just another Tuesday.’ But if you step back and think about it on a high-level basis, it’s really something special,” Pichler said. “It’s definitely profound.”
