A “classification” is when a volunteer or citizen scientist finishes marking up or sorting one image or other piece of data. Each classification done by volunteers for the Redshift Wrangler project tells us something about the distance and age of a far-away galaxy, bringing us one step closer to understanding how galaxies evolve. These volunteers met a major milestone this week: 200,000 classifications completed! 

That’s not all. The Redshift Wrangler project has received over 3,000 comments on Zooniverse talk boards, and has begun preparing a paper on their first batch of 11,000 galaxies. The paper will incorporate data from the DEep Imaging Multi-Object Spectrograph (DEIMOS) from NASA’s Keck Observatory Archive, as well as data from the Gemini and Subaru telescopes.

“NASA’s citizen science is a blessing, as I’ve found the Redshift Wrangler project to be such a rewarding experience,” said project volunteer, Baba Karthik Kalapatapu. “This project holds special meaning for me, as I had the unforgettable experience of visiting the Mauna Kea observatories, where I watched the Gemini North and Keck telescopes power on at sunset. I never could have imagined that I’d one day be working with data from those very telescopes—an incredible full-circle moment in my journey into understanding the cosmos.”

Ready to wrassle some distant galaxies yourself? Join the Redshift Wrangler project today! Lasso not required.

      NASA JPL is readying for, clockwise from lower right, the launches of CADRE (its engineering models are seen here), Lunar Trailblazer, NISAR (seen in an artist’s concept), Sentinel-6B (artist’s concept), and SPHEREx, as well as the Mars gravity assist of Europa Clipper (artist’s concept).NASA/JPL-Caltech/BAE Systems/Lockheed Martin Space Missions will study everything from water on the Moon to the transformation of our universe after the big bang and ongoing changes to Earth’s surface.
      With 2024 receding into the distance, NASA’s Jet Propulsion Laboratory is already deep into a busy 2025. Early in the new year, the Eaton Fire came close to JPL, destroying the homes of more than 200 employees, but work has continued apace to maintain mission operations and keep upcoming missions on track.
      Several missions managed by NASA JPL are prepping for launch this year. Most have been years in the making and launches are, of course, only part of the bigger picture. Other milestones are also on the docket for the federal laboratory, which Caltech manages for NASA.
      Here’s a glimpse of what lies ahead this year.
      Mysterious Universe
      Shaped like the bell of a trumpet and as big as a subcompact car, NASA’s SPHEREx space observatory is aiming for the stars. Known formally as the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, the mission will create four 3D maps of the entire sky in order to improve humanity’s understanding of the universe — how it expanded after the big bang, where ingredients of life can be found in ice grains, and much more. Target launch date: no earlier than Feb. 27 from Vandenberg Space Force Base in California.
      The Moon’s Icy Secrets
      NASA’s Lunar Trailblazer aims to help resolve an enduring mystery: Where is the Moon’s water? Scientists have seen signs suggesting it exists even where temperatures soar on the lunar surface, and there’s good reason to believe it can be found as surface ice in permanently shadowed craters, places that have not seen direct sunlight for billions of years. Managed by NASA JPL and led by Caltech, the small satellite will help provide answers, mapping the Moon’s surface water in unprecedented detail to determine the water’s abundance, location, form, and how it changes over time. The small satellite will hitch a ride, slated for late February, on the same launch as the Intuitive Machines-2 delivery to the Moon through NASA’s CLPS (Commercial Lunar Payload Services) initiative.
      Earth’s Changing Surface
      A collaboration between the United States and India, NISAR is a major addition to the fleet of satellites studying our changing planet. Short for NASA-Indian Space Research Organisation Synthetic Aperture Radar, the mission’s name is a nesting doll of acronyms, and the spacecraft is a nesting doll of capabilities: The first spacecraft to carry both L-band and S-band radars, it will see surface changes related to volcanoes, earthquakes, ice sheet motion, deforestation, and more in unprecedented detail after it launches in a few months’ time.
      Sea Level
      Targeting a November launch, Sentinel-6B will provide global sea surface height measurements — some of the most accurate data of its kind yet — that will improve climate models and hurricane tracking, as well as our understanding of phenomena like El Niño. A collaboration between NASA and ESA (European Space Agency), the spacecraft will take the baton from its twin, Sentinel-6 Michael Freilich, which launched in 2020. Together, the satellites are extending for another 10 years a nearly three-decade record of global sea surface height.
      Moon Rover Trio
      As a technology demonstration, the CADRE (Cooperative Autonomous Distributed Robotic Exploration) project marks another step NASA is taking toward developing robots that, by operating autonomously, can boost the efficiency of future missions. The project team at JPL will soon be packing up and shipping CADRE’s three suitcase-size rovers to Texas in preparation for their journey to the Moon aboard a commercial lander through one of NASA’s future CLPS deliveries. The rovers are designed to work together as a team without direct input from mission controllers back on Earth. And, by taking simultaneous measurements from multiple locations, they are meant to show how multirobot missions could enable new science and support astronauts.
      Quantum Technology
      Having arrived at the International Space Station in November, SEAQUE (Space Entanglement and Annealing QUantum Experiment) is testing two technologies that, if successful, could enable communication using entangled photons between two quantum systems. The research from this experiment, which gets underway in 2025, could help develop the building blocks for a future global quantum network that would allow equipment such as quantum computers to transfer data securely across large distances.
      Gravity Assist to Reach Jupiter
      Launched this past October, Europa Clipper will arrive at Jupiter in 2030 to investigate whether an ocean beneath the ice shell of the gas giant’s moon Europa has conditions suitable for life. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) to reach its destination. Since there are limitations on how much fuel the spacecraft can carry, mission planners are having Europa Clipper fly by Mars on March 1, using the planet’s gravity as a slingshot to add speed to its journey.

      NASA’s Stennis Space Center enjoyed an active 2024, marking several milestones and engaging in frontline activities in several key areas. A compilation video offers a look at 2024 highlights in such areas of work as propulsion testing, autonomous systems, range operations, community outreach, and STEM engagement. NASA’s Stennis Space Center near Bay St. Louis, Mississippi, celebrated propulsion testing and site operations milestones in 2024, all while inspiring the Artemis Generation and welcoming new leadership that will help NASA Stennis innovate and grow into the future.
      Featured highlights show a year of progress and vision, as NASA Stennis accelerates the exploration and commercialization of space, innovates to benefit NASA and industry, and leverages assets to grow as an impactful aerospace and technology hub.
      “These highlights are just a small snapshot of 2024 at NASA Stennis that show the future is bright,” Bailey said. “We have an incredibly talented and committed team of employees – and all of Mississippi can be proud of the work they do here at NASA Stennis. Together, with the Artemis Generation leading the way, we are returning to the Moon. Together, we are a part of something great.”
      New Center Leadership
      NASA Stennis Director John Bailey, right, and NASA Stennis Deputy Director Christine Powell stand near the United States Capitol during a visit to Washington, D.C. on Sept. 18. It marked the first visit to Capitol Hill for the center leaders since being named to their current roles. NASA/Stennis NASA Administrator Bill Nelson named John Bailey as director of NASA Stennis in April. Bailey had been serving as acting director since January 2024. “So much of NASA runs through Stennis,” said Nelson. “It is where we hone new and exciting capabilities in aerospace, technology, and deep space exploration. I am confident that John will lead the nation’s largest and premier propulsion test site to even greater success.”
      Four months later in August, Bailey announced that longtime propulsion engineer/manager Christine Powell had been selected as deputy director of NASA Stennis.
      Powell, the first woman selected as NASA Stennis deputy director, began her 33-year agency career as an intern at the center in 1991. She previously worked in multiple Engineering and Test Directorate roles, and most recently served as manager of the NASA Rocket Propulsion Test Program Office.
      Propulsion Activity
      NASA achieves a major milestone for future Artemis missions with successful completion of the second – and final – RS-25 engine certification test series April 3 on the Fred Haise Test Stand at NASA’s Stennis Space Center. NASA/Danny Nowlin NASA achieved major milestones for future Artemis missions at NASA Stennis in 2024. The NASA Stennis test team successfully completed a second – and final – RS-25 engine certification test series in April. The mission-critical series verified engine upgrades designed to enhance efficiency and reliability for future SLS (Space Launch System) missions.
      NASA Stennis crews also completed a safe lift and installation of the interstage simulator component in October needed for future testing of NASA’s exploration upper stage in the B-2 position of the Thad Cochran Test Stand. The component will function during Green Run testing like the SLS interstage section that helps protect the upper stage during Artemis launches.
      The test complex milestones support NASA’s goal of returning humans to the Moon and paving the way for future Mars exploration through Artemis missions.
      Commercial Testing
      NASA Stennis commercial tenant Rocket Lab completes a successful hot fire test of its Archimedes engine in its onsite test complex in the second half of 2024. Rocket Lab is one of numerous customers conducting test campaigns at NASA Stennis during the most recent year. Rocket Lab Already the nation’s largest multiuser propulsion test site, NASA Stennis aims to continue fueling growth of the commercial space market even further by working with aerospace companies to support a range of testing needs. In 2024, NASA Stennis supported work conducted by commercial companies such as Boeing, Blue Origin, Evolution Space, Launcher (a Vast company), Relativity Space, Rocket Lab, and Rolls-Royce.
      Officials from NASA Stennis and Roll-Royce also broke ground in June for a test pad located in the NASA Stennis E Test Complex. Rolls-Royce will conduct hydrogen testing for the Pearl 15 engine, which helps power the Bombardier Global 5500 & 6500 aircraft.
      ASTRA Mission Success
      Members of the NASA Stennis Autonomous Systems Laboratory team monitor the center’s in-space satellite payload from the onsite ASTRA (Autonomous Satellite Technology for Resilient Applications) Payload Operation Command Center. The ASTRA payload launched aboard the Sidus Space LizzieSat-1 small satellite in March 2024, with the NASA Stennis team announcing in July that it had achieved primary mission objectives. In September, the team announced the ASTRA mission would continue during the satellite’s planned four-year mission.NASA/Danny Nowlin In July, NASA Stennis and commercial partner Sidus Space Inc. announced primary mission success for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite.
      ASTRA (Autonomous Satellite Technology for Resilient Applications) is the on-orbit payload mission developed by NASA Stennis. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space premier satellite, LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation, which allowed the NASA Stennis ASTRA team to complete its primary mission objectives.
      NASA Stennis announced in September it will continue the center’s in-space autonomous systems payload mission through a follow-on agreement with Sidus Space Inc.
      Range Operations
      The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area. Skydweller Aero During 2024, NASA Stennis entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a step towards achieving a strategic center goal.
      The agreement marked the first Reimbursable Space Act agreement between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems.
      The company announced in October it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours.
      NASA Engagement
      NASA Stennis representatives inspire the Artemis Generation at the NAS Pensacola Blue Angels Homecoming Air Show on Nov. 1-2. NASA’s exhibits at the air show honored 55th anniversary of the Apollo 11 lunar landing and showcased the agency’s mission to inspire the world through discovery. NASA/Stennis NASA representatives participated in a variety of outreach activities during the past year to create meaningful connections with the Artemis Generation.
      The NASA ASTRO CAMP® Community Partners program, which originated at the south Mississippi NASA center, surpassed previous milestone marks in fiscal year 2024 by partnering with 373 community sites, including 50 outside the United States, to inspire youth, families, and educators. 
      NASA Stennis also supported STEM (science, technology, engineering, and mathematics) engagement during the year. It once again joined with NASA’s Robotics Alliance Project and co-sponsor Mississippi Power to support the second annual For the Inspiration and Recognition of Science and Technology (FIRST) Robotics Magnolia Regional Competition in Laurel, Mississippi. The event attracted 37 high school teams from eight states and one from Mexico.
      The center also supported NASA activities during the 2024 total solar eclipse. In addition, it hosted informational efforts and exhibits at high-visibility events such as the 51st Annual Bayou Classic, and Essence Fest in New Orleans.

      Panama and Austria signed the Artemis Accords Wednesday during separate signing ceremonies at NASA Headquarters in Washington, becoming the 49th and 50th nations to commit to the responsible exploration of space for all humanity.
      “NASA welcomes Panama and Austria to the Artemis Accords community and celebrates 50 countries united by shared principles for the safe and responsible exploration of space,” NASA Administrator Bill Nelson said. “More than ever before, NASA is opening space to more nations and more people for the benefit of all. Together we are building long-term and peaceful deep space exploration for the Artemis Generation.”
      In just a few years, the original group of eight country signatories including the United States has multiplied, with 17 countries signings in 2024. More than a number, the Artemis Accords represent a robust community, from every region of the world, unified by the same goal: to ensure safe and responsible civil space exploration.  
      Through the Artemis Accords, the United States and other signatories are progressing toward continued safe and sustainable exploration of space with concrete outcomes. They committed to a method of operation and set of recommendations on non-interference, interoperability, release of scientific data, long-term sustainability guidelines, and registration to advance the implementation of the Artemis Accords. 
      Potential focus areas for the next year include further advancing sustainability, including debris management for both lunar orbit and the surface of the Moon. 
      Austria Joins Artemis Accords
      Petra Schneebauer, ambassador of the Republic of Austria to the United States, signed the accords on behalf of Austria, becoming the 50th country signatory.
      “Austria is proud to sign the Artemis Accords, an important step in fostering international cooperation for the civil exploration of the Moon and expanding humanity’s presence in the cosmos,” said Schneebauer. “By signing the Accords, we reaffirm our commitment to the peaceful, responsible, and cooperative use of space while emphasizing our support for strong multilateral partnerships and scientific progress. This cooperation will open new prospects for Austrian businesses, scientists, and research institutions to engage in pioneering space initiatives.”
      Jennifer Littlejohn, acting assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, also participated in Austria’s signing event.
      Panama Joins Artemis Accords
      Earlier Wednesday, Nelson hosted Panama for a signing ceremony. José Miguel Alemán Healy, ambassador of the Republic of Panama to the United States, signed the Artemis Accords on behalf of Panama. Principal Deputy Assistant Secretary Tony Fernandes for U.S. Department of State’s Bureau of Oceans and International Environmental and Scientific Affairs also participated in the event.

It is a bold commitment to peaceful exploration, scientific discovery, and international collaboration.”
      In 2020, the United States, led by NASA with the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords, identifying a set of principles promoting the beneficial use of space for humanity.
      The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data.   
      The accords are a voluntary commitment to engage in safe, transparent, responsible behavior in space, and any nation that wants to commit to those values is welcome to sign.

      In 2022 NASA’s DART spacecraft made history, and changed the Solar System forever, by impacting the Dimorphos asteroid and measurably shifting its orbit around the larger Didymos asteroid. In the process a plume of debris was thrown out into space.
      The latest modelling, available on the preprint server arXiv and accepted for publication in the September volume of The Planetary Science Journal, shows how small meteoroids from that debris could eventually reach both Mars and Earth – potentially in an observable (although quite safe) manner.
