4 Min Read NASA Seeks Input for Astrobee Free-flying Space Robots
iss069e010815 (May 16, 2023) — UAE (United Arab Emirates) astronaut and Expedition 69 Flight Engineer Sultan Alneyadi observes a free-flying Astrobee robotic assistant during the testing of its operations for an upcoming student competition to control the robotic devices. Credits: NASA NASA is seeking input from American companies for the operation and use of a system of free-flying robots aboard the International Space Station as the agency continues to foster scientific, educational, and technological developments in low Earth orbit for the benefit of all.
The colorful, cube-shaped robots – named “Bumble,” “Honey,” and “Queen” – are part of the Astrobee system helping astronauts and researchers perform technology demonstrations, scientific research, and STEM (science, technology, engineering and mathematics) activities in the unique environment of space since 2018.
“Dozens of institutions collaborate with NASA to use the Astrobee system to test new hardware and software technologies,” said Jose Benavides, project manager for the Astrobee facilities at NASA’s Ames Research Center in California’s Silicon Valley, where the system was designed and built. “I’m excited to hear how respondents think Astrobee can continue to advance robotics in space.”
NASA issued a Request for Information to inform strategic planning, inviting industry to provide information to help shape the maturation of robotics in zero gravity to achieve the greatest scientific and exploration value. Responses are due Sept. 27, 2024. To learn more about the Request for Information, visit:

iss065e389375 (9/20/2021) — NASA astronaut Shane Kimbrough poses with the Astrobee robotic free-flyers in support of the Kibo Robot Programming Challenge (Robo-Pro Challenge). The Kibo-RPC, allows students to create programs to control Astrobee, a free-flying robot aboard the International Space Station (ISS). The battery-powered robots in the Astrobee system fly around the space station’s modules using electric fans for propulsion and “see” their surroundings using lights, cameras, and other sensors. They have interchangeable “arms” that provide ways for the robots to hold objects or keep steady for tasks requiring stability, and magnets to ensure they stay securely docked when recharging.
Working autonomously, or via remote control by astronauts, flight controllers, or researchers on the ground, the robots can be used to off-load time-consuming tasks. For instance, the robots can work independently or collaboratively to assist with routine chores like space station monitoring, maintenance, inventory, experiment documentation, or moving cargo throughout the station. This allows astronauts more time to tackle complex work that only humans can perform.
Astrobee’s versatile design has allowed thousands of hours of testing on hundreds of microgravity experiments. Many have involved astronauts, but the facility also is regularly used by researchers and student teams across the world competing for the opportunity to run their programs on the robots in space.
Further developing human-robotic technology will pave the way for future crewed and uncrewed spacecraft maintenance and exploration tasks done by robots both off-planet and in deep space"
Jonathan Barlow
Astrobee Project Manager
For example, NASA’s ISAAC (Integrated System for Autonomous and Adaptive Caretaking) project, used the Astrobees to study how robots could assist spacecraft, vehicle systems, and ground operators. The technology could help NASA use robot caretakers for critical spacecraft in the agency’s Moon-to-Mars plans, including the Gateway lunar space station and Mars transit habitat vehicle, especially during the months-long periods when these spacecraft will be uncrewed.
“Our ISAAC work has proved out its technology in a high-fidelity space environment because of the ready availability of the capable Astrobee robots,” said Trey Smith, project manager for ISAAC at NASA Ames.
The project demonstrated using multiple Astrobees to autonomously collect the first robot-generated survey of a spacecraft interior. Other ISAAC firsts include the first use of a robot to locate the source of a sound in space, in collaboration with the Bosch USA SoundSee payload team, and the first time robots navigated between modules of a space station. Future robots could use ISAAC technology to transfer cargo between space vehicles or respond to a time-critical fault like a leak due to a micrometeoroid impact, all without human assistance.
“With Astrobee, we’ve learned about flying multiple robots in space alongside humans,” said Jonathan Barlow, project manager for Astrobee at NASA Ames. “Further developing human-robotic technology will pave the way for future crewed and uncrewed spacecraft maintenance and exploration tasks done by robots both off-planet and in deep space.”
The Astrobee Facility, operated out of NASA’s Ames Research Center, provides a free-flying robotic system for space station research and STEM outreach. NASA’s Game Changing Development Program, part of the agency’s Space Technology Mission Directorate, funded Astrobee. NASA’s International Space Station Utilization Office provides ongoing funding.
iss071e464314 (Aug. 12, 2024) — NASA astronaut and Expedition 71 Flight Engineer Jeanette Epps monitors a pair of Astrobee robotic free-flying assistants as they demonstrate autonomous docking maneuvers inside the International Space Station’s Kibo laboratory module. The cube-shaped, toaster-sized devices were operating with a connecting interface system, called CLINGERS with an embedded navigation sensor, that may benefit construction in space.View the full article

On 8 September 2024, the first of four satellites that make up ESA’s Cluster mission will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area.
This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.
This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in sustainable space exploration.

NASA Citizen Scientists Spot Object Moving 1 Million Miles Per Hour
This artist’s concept shows a hypothetical white dwarf, left, that has exploded as a supernova. The object at right is CWISE J1249, a star or brown dwarf ejected from this system as a result of the explosion. This scenario is one explanation for where CWISE J1249 came from. W.M. Keck Observatory/Adam Makarenko Most familiar stars peacefully orbit the center of the Milky Way. But citizen scientists working on NASA’s Backyard Worlds: Planet 9 project have helped discover an object moving so fast that it will escape the Milky Way’s gravity and shoot into intergalactic space. This hypervelocity object is the first such object found with the mass similar to or less than that of a small star.
Backyard Worlds uses images from NASA’s WISE, or Wide Field Infrared Explorer, mission, which mapped the sky in infrared light from 2009 to 2011. It was re-activated as NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) in 2013 and retired on Aug. 8, 2024.
A few years ago, longtime Backyard Worlds citizen scientists Martin Kabatnik, Thomas P. Bickle, and Dan Caselden spotted a faint, fast-moving object called CWISE J124909.08+362116.0, marching across their screens in the WISE images. Follow-up observations with several ground-based telescopes helped scientists confirm the discovery and characterize the object. These citizen scientists are now co-authors on the team’s study about this discovery published in the Astrophysical Journal Letters (a pre-print version is available here).
“I can’t describe the level of excitement,” said Kabatnik, a citizen scientist from Nuremberg, Germany. “When I first saw how fast it was moving, I was convinced it must have been reported already.”
CWISE J1249 is zooming out of the Milky Way at about 1 million miles per hour. But it also stands out for its low mass, which makes it difficult to classify as a celestial object. It could be a low-mass star, or if it doesn’t steadily fuse hydrogen in its core, it would be considered a brown dwarf, putting it somewhere between a gas giant planet and a star.
Ordinary brown dwarfs are not that rare. Backyard Worlds: Planet 9 volunteers have discovered more than 4,000 of them! But none of the others are known to be on their way out of the galaxy.
This new object has yet another unique property. Data obtained with the W. M. Keck Observatory in Maunakea, Hawaii, show that it has much less iron and other metals than other stars and brown dwarfs. This unusual composition suggests that CWISE J1249 is quite old, likely from one of the first generations of stars in our galaxy.
Why does this object move at such high speed? One hypothesis is that CWISE J1249 originally came from a binary system with a white dwarf, which exploded as a supernova when it pulled off too much material from its companion. Another possibility is that it came from a tightly bound cluster of stars called a globular cluster, and a chance meeting with a pair of black holes sent it soaring away.
“When a star encounters a black hole binary, the complex dynamics of this three-body interaction can toss that star right out of the globular cluster,” says Kyle Kremer, incoming assistant professor in UC San Diego’s Department of Astronomy and Astrophysics.
Scientists will look more closely at the elemental composition of CWISE J1249 for clues about which of these scenarios is more likely.
This discovery has been a team effort on multiple levels—a collaboration involving volunteers, professionals, and students. Kabatnik credits other citizen scientists with helping him search, including Melina Thévenot, who “blew my mind with her personal blog about doing searches using Astronomical Data Query Language,” he said. Software written by citizen scientist Frank Kiwy was also instrumental in this finding, he said.
The study is led by Backyard Worlds: Planet 9 science team member Adam Burgasser, a professor at the University of California, San Diego, and includes co-authors Hunter Brooks and Austin Rothermich, astronomy students who both began their astronomy careers as citizen scientists.

NASA This view of the Earth’s crest over the lunar horizon was taken on July 29, 1971, during the Apollo 15 lunar landing mission. Astronauts David Scott, Alfred Worden, and James Irwin launched from NASA’s Kennedy Space Center in Florida aboard a Saturn V launch vehicle.
Designed to explore the Moon over longer periods, greater ranges, and with more instruments for the collection of scientific data than before, Apollo 15 included the introduction of a $40 million lunar roving vehicle (LRV) that reached a top speed of 10 mph (16 kph) across the Moon’s surface.
Upon landing on the Moon at the Hadley-Apennine site, Scott and Irwin conducted four spacewalks, including three excursions using the LRV, for a combined total of 19 hours. Worden remained in orbit aboard the command module Endeavour.

A proposal entitled, “TEMPO-EMIT synergy: Enhancing applications of GHG (greenhouse gas) and air pollutant observations over key emission sources,” was selected for funding through a NASA cross-mission product opportunity. The project, co-led by Aaron Naeger at SPoRT, will integrate the complementary air pollutant and GHG data from the NASA TEMPO and EMIT missions for designing a TEMPO-EMIT merged product concept, which aims to facilitate assessments of GHG and co-pollutant emissions from key source regions in the U.S. The focus of this project will be on the oil and gas operations in the Permian Basin where recent data have indicated strong nitrogen dioxide and methane emissions from the facilities. The National Park Service and air agencies have a high-level of interest in better understanding emissions from these facilities for improving air quality management in the region.
