An artist's concept of the Starling swarm. Four small CubeSat spacecraft orbit in linear formation with Earth visible below.
The four CubeSate spacecraft that make up the Starling swarm have demonstrated success in autonomous operations, completing all key mission objectives.

After ten months in orbit, the Starling spacecraft swarm successfully demonstrated its primary mission’s key objectives, representing significant achievements in the capability of swarm configurations. 

Swarms of satellites may one day be used in deep space exploration. An autonomous network of spacecraft could self-navigate, manage scientific experiments, and execute maneuvers to respond to environmental changes without the burden of significant communications delays between the swarm and Earth. 

“The success of Starling’s initial mission represents a landmark achievement in the development of autonomous networks of small spacecraft,” said Roger Hunter, program manager for NASA’s Small Spacecraft Technology program at NASA’s Ames Research Center in California’s Silicon Valley. “The team has been very successful in achieving our objectives and adapting in the face of challenges.”  

Sharing the Work

The Distributed Spacecraft Autonomy (DSA) experiment, flown onboard Starling, demonstrated the spacecraft swarm’s ability to optimize data collection across the swarm. The CubeSats analyzed Earth’s ionosphere by identifying interesting phenomena and reaching a consensus between each satellite on an approach for analysis.  

By sharing observational work across a swarm, each spacecraft can “share the load” and observe different data or work together to provide deeper analysis, reducing human workload, and keeping the spacecraft working without the need for new commands sent from the ground. 

The experiment’s success means Starling is the first swarm to autonomously distribute information and operations data between spacecraft to generate plans to work more efficiently, and the first demonstration of a fully distributed onboard reasoning system capable of reacting quickly to changes in scientific observations. 

Communicating Across the Swarm

A swarm of spacecraft needs a network to communicate between each other. The Mobile Ad-hoc Network (MANET) experiment automatically established a network in space, allowing the swarm to relay commands and transfer data between one another and the ground, as well as share information about other experiments cooperatively.  

The team successfully completed all the MANET experiment objectives, including demonstrating routing commands and data to one of the spacecraft having trouble with space to ground communications, a valuable benefit of a cooperative spacecraft swarm. 

“The success of MANET demonstrates the robustness of a swarm,” said Howard Cannon, Starling project manager at NASA Ames. “For example, when the radio went down on one swarm spacecraft, we ‘side-loaded’ the spacecraft from another direction, sending commands, software updates, and other vital information to the spacecraft from another swarm member.” 

Autonomous Swarm Navigation 

Navigating and operating in relation to one another and the planet is an important part of forming a swarm of spacecraft. Starling Formation-Flying Optical Experiment, or StarFOX, uses star trackers to recognize a fellow swarm member, other satellite, or space debris from the background field of stars, then estimate each spacecraft’s position and velocity. 

The experiment is the first-ever published demonstration of this type of swarm navigation, including the ability to track multiple members of a swarm simultaneously and the ability to share observations between the spacecraft, improving accuracy when determining each swarm member’s orbit. 

Near the end of mission operations, the swarm was maneuvered into a passive safety ellipse, and in this formation, the StarFOX team was able to achieve a groundbreaking milestone, demonstrating the ability to autonomously estimate the swarm’s orbits using only inter-satellite measurements from the spacecraft star trackers. 

Managing Swarm Maneuvers 

The ability to plan and execute maneuvers with minimal human intervention is an important part of developing larger satellite swarms. Managing the trajectories and maneuvers of hundreds or thousands of spacecraft autonomously saves time and reduces complexity. 

The Reconfiguration and Orbit Maintenance Experiments Onboard (ROMEO) system tests onboard maneuver planning and execution by estimating the spacecraft’s orbit and planning a maneuver to a new desired orbit. 

The experiment team has successfully demonstrated the system’s ability to determine and plan a change in orbit and is working to refine the system to reduce propellant use and demonstrate executing the maneuvers. The team will continue to adapt and develop the system throughout Starling’s mission extension. 

Swarming Together

Now that Starling’s primary mission objectives are complete, the team will embark on a mission extension known as Starling 1.5, testing space traffic coordination in partnership with SpaceX’s Starlink constellation, which also has autonomous maneuvering capabilities. The project will explore how constellations operated by different users can share information through a ground hub to avoid potential collisions.  

“Starling’s partnership with SpaceX is the next step in operating large networks of spacecraft and understanding how two autonomously maneuvering systems can safely operate in proximity to each other. As the number of operational spacecraft increases each year, we must learn how to manage orbital traffic,” said Hunter. 

NASA’s Small Spacecraft Technology program, based at Ames and within NASA’s Space Technology Mission Directorate (STMD), funds and manages the Starling mission. Blue Canyon Technologies designed and manufactured the spacecraft buses and is providing mission operations support. Rocket Lab USA, Inc. provided launch and integration services. Partners supporting Starling’s payload experiments have included Stanford University’s Space Rendezvous Lab in Stanford, California, York Space Systems (formerly Emergent Space Technologies) of Denver, Colorado, CesiumAstro of Austin, Texas, L3Harris Technologies, Inc., of Melbourne, Florida. Funding support for the DSA experiment was provided by NASA’s Game Changing Development program within STMD. Partners supporting Starling’s mission extension include SpaceX of Hawthorne, California, NASA’s Conjunction Assessment Risk Analysis (CARA) program, and the Department of Commerce. SpaceX manages the Starlink satellite constellation and the Collision Avoidance ground system.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      SpaceX Crew-9 members (from left) Mission Specialist Aleksandr Gorbunov from Roscosmos and Commander Nick Hague from NASA pose for an official crew portrait at NASA’s Johnson Space Center in Houston, Texas.NASA/Josh Valcarel NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are preparing to launch on the agency’s SpaceX Crew-9 mission to the International Space Station.
      The flight is the ninth crew rotation mission with SpaceX to the station under NASA’s Commercial Crew Program. The duo will lift off aboard the SpaceX Dragon spacecraft, which previously flew NASA’s SpaceX Crew-4, Axiom Mission 2 and Axiom Mission 3, from Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
      Once aboard the space station, Hague and Gorbunov will become members of the Expedition 72 crew and perform research, technology demonstrations, and maintenance activities. The pair will join NASA astronauts Don Petitt, Butch Wilmore, Suni Williams, as well as Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner.
      Wilmore and Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.
      Launch preparations are underway, and teams are working to integrate the spacecraft and the SpaceX Falcon 9 rocket, including checkouts of a second flight rocket booster  for the mission. The integrated spacecraft and rocket will then be rolled to the pad and raised to the vertical position for a dry dress rehearsal with the crew and an integrated static fire test prior to launch.
      The Crew
      Nick Hague will serve as crew commander for Crew-9, making this his third launch and second mission to the space station. During his first launch in October 2018, Hague and his crewmate, Roscosmos’ Alexey Ovchinin, experienced a rocket booster failure, resulting in an in-flight, post-launch abort, ballistic re-entry, and safe landing in their Soyuz MS-10 spacecraft. Five months later, Hague launched aboard Soyuz MS-12 and served as a flight engineer aboard the space station during Expeditions 59 and 60. Hague has spent 203 days in space and conducted three spacewalks to upgrade space station power systems and install a docking adapter for commercial spacecraft.
      Born in Belleville, Kansas, Hague earned a bachelor’s degree in Astronautical Engineering from the United States Air Force Academy and a master’s degree in Aeronautical and Astronautical Engineering from the Massachusetts Institute of Technology in Cambridge, Massachusetts. Hague was selected as an astronaut by NASA in 2013. An active-duty colonel in the U.S. Space Force, Hague completed a developmental rotation at the Defense Department and served as the Space Force’s director of test and evaluation from 2020 to 2022. In August 2022, Hague resumed duties at NASA, working on the Boeing Starliner Program until this flight assignment.
      Follow @astrohague on X and Instagram.
      Roscosmos cosmonaut Aleksandr Gorbunov will embark on his first trip to the space station as a mission specialist for Crew-9. Born in Zheleznogorsk, Kursk region, Russia, he studied engineering with qualifications in spacecraft and upper stages from the Moscow Aviation Institute. Gorbunov graduated from the military department with a specialty in operating and repairing aircraft, helicopters, and aircraft engines. Before his selection as a cosmonaut in 2018, he worked as an engineer for Rocket Space Corp. Energia and supported cargo spacecraft launches from the Baikonur Cosmodrome. Gorbunov will serve as a flight engineer during Expedition 71/72 aboard the space station.
      Mission Overview
      After liftoff, Dragon will accelerate to approximately 17,500 mph to dock with the space station.
      Once in orbit, flight control teams from NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston and the SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually if necessary.
      After docking, Expedition 71 will welcome Hague and Gorbunov inside the station and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-8 mission. After a handover period, NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin of Crew-8 will undock from the space station and splash down off the coast of Florida.
      Crew-9 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include the impact of flame behavior on Earth, studying cells and platelets during long-duration spaceflight, and a B vitamin that could reduce Spaceflight-Associated Neuro-ocular Syndrome. They’ll also work on experiments that benefit life on Earth, like studying the physics of supernova explosions and monitoring the effects of different moister treatments on plants grown aboard the station. These are just a few of over 200 scientific experiments and technology demonstrations taking place during their mission.
      While aboard the orbiting laboratory, Crew-9 will welcome two Dragon spacecraft, including NASA’s SpaceX’s 31st commercial resupply services mission and NASA’s SpaceX Crew-10, and two Roscosmos-led cargo deliveries on Progress 90 and 91.
      In February, Hague, Gorbunov, Wilmore, and Williams will climb aboard Dragon and autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore.
      Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing research, and developing the skills needed to operate future commercial destinations in low Earth orbit, and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA astronaut Tracy C. Dyson smiles for a portrait in the vestibule between the Kibo laboratory module and the Harmony module aboard space station.NASA NASA astronaut Tracy C. Dyson is returning home after a six-month mission aboard the International Space Station. While on orbit, Dyson conducted an array of experiments and technology demonstrations that contribute to advancements for humanity on Earth and the agency’s trajectory to the Moon and Mars. 
      Here is a look at some of the science Dyson conducted during her mission: 
      Heart-Shaped Bioprints 
      NASA NASA astronaut Tracy C. Dyson operates the BioFabrication Facility for the Redwire Cardiac Bioprinting Investigation, which 3D prints cardiovascular tissue samples. In microgravity, bio inks used for 3D printing are less likely to settle and retain their shape better than on Earth. Cardiovascular disease is currently the number one cause of death in the United States, and findings from this space station investigation could one day lead to 3D-printed organs such as hearts for patients awaiting transplants. 
      Wicking in Weightlessness 
      NASA NASA astronaut Tracy C. Dyson handles hardware for the Wicking in Gel-Coated Tubes (Gaucho Lung) experiment. This study uses a tube lined with various gel thicknesses to simulate the human respiratory system. A fluid mass known as a liquid plug is then observed as it either blocks or flows through the tube. Data regarding the movement and trailing of the liquid plug allows researchers to design better drug delivery methods to address respiratory ailments. 
      Programming for Future Missions 
      NASA NASA NASA astronaut Tracy C. Dyson runs student-designed software on the free-flying Astrobee robot. This technology demonstration is part of Zero Robotics, a worldwide competition that engages middle school students in writing computer code to address unique specifications. Winning participants get to run their software on an actual Astrobee aboard the space station. This educational opportunity helps inspire the next generation of technology innovators.     
      Robo-Extensions
      NASA As we venture to the Moon and Mars, astronauts may rely more on robots to ensure safety and preserve resources. Through the Surface Avatar study, NASA astronaut Tracy C. Dyson controls a robot on Earth’s surface from a computer aboard station. This technology demonstration aims to toggle between manipulating multiple robots and “diving inside” a specific bot to control as an avatar. This two-way demonstration also evaluates how robot operators respond their robotic counterparts’ efficiency and general output. Applications for Earth use include exploration of inhospitable zones and search and rescue missions after disasters.  
      Capturing Earth’s Essence
      NASA For Crew Earth Observations, astronauts take pictures of Earth from space for research purposes. NASA astronauts Suni Williams (left) and Tracy C. Dyson (right) contribute by aiming handheld cameras from the space station’s cupola to photograph our planet. Images help inform climate and environmental trends worldwide and provide real-time natural disaster assessments. More than four million photographs have been taken of Earth by astronauts from space.  
      Multi-faceted Crystallization Processor 
      NASA NASA astronaut Tracy C. Dyson holds a cassette for Pharmaceutical In-Space Laboratory – 04 (ADSEP-PIL-04), an experiment to crystallize the model proteins lysozyme and insulin. Up to three cassettes with samples can be processed simultaneously in the Advanced Space Experiment Processor (ADSEP), each at an independent temperature. Because lysozyme and insulin have well-documented crystal structures, they can be used to evaluate the hardware’s performance in space. Successful crystallization with ADSEP could lead to production and manufacturing of versatile crystals with pharmaceutical applications.  
      Cryo Care  
      NASA NASA astronauts Tracy C. Dyson and Matthew Dominick preserve research samples in freezers aboard the space station. Cryopreservation is essential for maintaining the integrity of samples for a variety of experiments, especially within the field of biology. The orbiting laboratory has multiple freezer options with varying subzero temperatures. Upon return, frozen samples are delivered back to their research teams for further analysis.    
      Welcoming New Science 
      NASA NASA astronaut Tracy C. Dyson is pictured between the Unity module and Northrop Grumman’s Cygnus spacecraft in preparation for depressurization and departure from the International Space Station. On long-duration missions, visiting vehicles provide necessities for crew daily living as well as new science experiments and supplies for ongoing research. This vehicle brought experiments to test water recovery technology, produce stem cells in microgravity, study the effects of spaceflight on microorganism DNA, and conduct science demonstrations for students.

      This enormous piece of space hardware is NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus, which will maneuver the observatory to its place in space and enable it to function while there. It is photographed here in the largest clean room at NASA’s Goddard Space Flight Center, where engineers are inspecting it upon delivery. The bus rests atop an aluminum ring that will temporarily protect its underside. The two copper-colored flaps are Roman’s Lower Instrument Sun Shade –– deployable panels designed to help shield the observatory from sunlight.NASA/Chris Gunn The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.
      Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself.
      “They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said Jackie Townsend, the Roman deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s really more like an RV because it has a whole assortment of functions that enable Roman to accomplish its scientific goals while out there too.”
      Those goals include surveying wide swaths of the universe to study things like: dark energy, a mysterious cosmic pressure thought to accelerate the universe’s expansion; dark matter, invisible matter seen only via its gravitational influence; and exoplanets, worlds beyond our solar system.
      The mission’s science wouldn’t be possible without a spacecraft to transport the telescope, point the observatory toward different cosmic targets, provide power, communicate with Earth, control and store instrument data, and regulate Roman’s temperature. Nearly 50 miles of electrical cabling are laced throughout the assembly to enable different parts of the observatory to communicate with each other.
      The spacecraft will also deploy several major elements that will be stowed for launch, including the solar panels, deployable aperture cover, lower instrument Sun shade, and high-gain antenna. It’s also responsible for collecting and beaming down data, which is no small task for a space observatory that will survey the cosmos like Roman will.
      “Roman will send back 1.4 terabytes of data per day, compared to about 50 to 60 gigabytes from the James Webb Space Telescope and three gigabytes from the Hubble Space Telescope,” said Jason Hylan, the Roman observatory manager at NASA Goddard. “Webb’s daily downlink is roughly comparable to 13 hours of YouTube video at the highest quality while Roman’s would amount to about 2 weeks.”
      This top-down view shows NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus from another angle. It rests atop an aluminum ring that will not be part of the observatory and is surrounded by an enclosure used in testing to ensure electromagnetic interference will not affect the bus’s sensitive electronics. The bus is covered in gray bagging material to prevent contamination –– even tiny stray particles could affect its performance.NASA/Chris Gunn A Goddard Grand Slam
      This milestone is the culmination of eight years of spacecraft design work, building, and testing by hundreds of people at Goddard.
      “Goddard employees were the brains, designers, and executors. And they worked with vendors who supplied all the right parts,” Townsend said. “We leaned on generations of expertise in the spacecraft arena to work around cost and schedule challenges that arose from supply chain issues and the pandemic.”
      One time- and money-saving technique the team came up with was building a spacecraft mockup, called the structural verification unit. That allowed them to do two things at once: complete strength testing on the mockup, designed specifically for that purpose, while also assembling the actual spacecraft.
      The spacecraft’s clever layout also allowed the team to adapt to changing schedules. It’s designed to be modular, “more like Trivial Pursuit pie pieces than a nesting egg, where interior components are buried inside,” Townsend said. “That’s been a game-changer because you can’t always count on things arriving in the order you planned or working perfectly right away with no tweaks.” It also increased efficiency because people could work on different portions of the bus at the same time without interfering with each other.
      The slightly asymmetrical and hexagonal spacecraft bus is about 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms).
      While it may look small in this photo, the spacecraft bus for NASA’s Nancy Grace Roman Space Telescope is 8 feet (2.5 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms). In this photo, it rests atop an aluminum ring that will not be part of the observatory. The bundles of wires on top are part of more than 50 miles of cabling laced throughout the assembly to enable different parts of the observatory to communicate with each other.NASA/Chris Gunn One reason it doesn’t weigh more is that some components have been partially hollowed out. If you could peel back some of the spacecraft’s panels, you’d find superthin metallic honeycomb sandwiched between two slim layers of metal. And many of the components, such as the antenna dish, are made of strong yet lightweight composite materials.
      When the spacecraft bus was fully assembled, engineers conducted a comprehensive performance test. Prior to this, each component had been tested individually, but just like with a sports team, the whole unit has to perform well together.
      “The spacecraft passed the test, and now we’re getting ready to install the payload –– Roman’s instruments and the telescope itself,” said Missie Vess, a spacecraft systems engineer for Roman at NASA Goddard. “Next year, we’ll test these systems together and begin integrating the final components of the observatory, including the deployable aperture cover, outer barrel assembly, and solar panels. Then we’ll finally have ourselves a complete observatory, on track for launch by May 2027.”

      The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept depicts NASA’s Europa Clipper spacecraft in orbit around Jupiter. The mission is targeting an Oct. 10, 2024, launch.NASA/JPL-Caltech The first NASA spacecraft dedicated to studying an ocean world beyond Earth, Europa Clipper aims to find out if the ice-encased moon Europa could be habitable.
      NASA’s Europa Clipper spacecraft, the largest the agency has ever built for a planetary mission, will travel 1.8 billion miles (2.9 billion kilometers) from the agency’s Kennedy Space Center in Florida to Europa, an intriguing icy moon of Jupiter. The spacecraft’s launch period opens Thursday, Oct. 10.
      Learn more about how NASA’s Europa Clipper came together – and how it will explore an ocean moon of Jupiter. Credit: NASA/JPL-Caltech  Data from previous NASA missions has provided scientists with strong evidence that an enormous salty ocean lies underneath the frozen surface of the moon. Europa Clipper will orbit Jupiter and conduct 49 close flybys of the moon to gather data needed to determine whether there are places below its thick frozen crust that could support life.
      Here are eight things to know about the mission:
      1. Europa is one of the most promising places to look for currently habitable conditions beyond Earth.
      There’s scientific evidence that the ingredients for life — water, the right chemistry, and energy — may exist at Europa right now. This mission will gather the information scientists need to find out for sure. The moon may hold an internal ocean with twice the water of Earth’s oceans combined, and it may also host organic compounds and energy sources under its surface. If the mission determines that Europa is habitable, it would mean there may be more habitable worlds in our solar system and beyond than we have imagined.
      2. The spacecraft will fly through one of the most punishing radiation environments in our solar system — second only to the Sun’s.
      Jupiter is surrounded by a gigantic magnetic field 20,000 times stronger than Earth’s. As the field spins, it captures and accelerates charged particles, creating radiation that can damage spacecraft. Mission engineers designed a spacecraft vault to shield sensitive electronics from radiation, and they plotted orbits that will limit the time Europa Clipper spends in most radiation-heavy areas around Jupiter.
      3. Europa Clipper will orbit Jupiter, studying Europa while flying by the moon dozens of times.
      The spacecraft will make looping orbits around Jupiter that bring it close to Europa for 49 science-dedicated flybys. On each orbit, the spacecraft will spend less than a day in Jupiter’s dangerous radiation zone near Europa before zipping back out. Two to three weeks later, it will repeat the process, making another flyby.
      4. Europa Clipper features NASA’s most sophisticated suite of science instruments yet.
      To determine if Europa is habitable, Europa Clipper must assess the moon’s interior, composition, and geology. The spacecraft carries nine science instruments and a gravity experiment that uses the telecommunications system. In order to obtain the best science during each flyby, all the science instruments will operate simultaneously on every pass. Scientists will then layer the data together to paint a full picture of the moon.
      5. With antennas and solar arrays fully deployed, Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission.
      The spacecraft extends 100 feet (30.5 meters) from one end to the other and about 58 feet (17.6 meters) across. That’s bigger than a basketball court, thanks in large part to the solar arrays, which need to be huge so they can collect enough sunlight while near Jupiter to power the instruments, electronics, and other subsystems.
      6. It’s a long journey to Jupiter.
      Jupiter is on average some 480 million miles (about 770 million kilometers) from Earth; both planets are in motion, and a spacecraft can carry only a limited amount of fuel. Mission planners are sending Europa Clipper past Mars and then Earth, using the planets’ gravity as a slingshot to add speed to the spacecraft’s trek. After journeying about 1.8 billion miles (2.9 billion kilometers) over 5½ years, the spacecraft will fire its engines to enter orbit around Jupiter in 2030.
      7. Institutions across the U.S. and Europe have contributed to Europa Clipper.
      Currently, about a thousand people work on the mission, including more than 220 scientists from both the U.S. and Europe. Since the mission was officially approved in 2015, more than 4,000 people have contributed to Europa Clipper, including teams who work for contractors and subcontractors.
      8. More than 2.6 million of us are riding along with the spacecraft, bringing greetings from one water world to another.
      As part of a mission campaign called “Message in a Bottle,” the spacecraft is carrying a poem by U.S. Poet Laureate Ada Limón, cosigned by millions of people from nearly every country in the world. Their names have been stenciled onto a microchip attached to a tantalum metal plate that seals the spacecraft’s electronics vault. The plate also features waveforms of people saying the word “water” in over 100 spoken languages.
      More About Europa Clipper
      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 the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall 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.
