The OLI (Operational Land Imager) on Landsat 8 captured an image of Kachemak Bay’s turbid, cloudy waters on September 20, 2024. This cloudiness comes from glacial flour: bits of pulverized rock ground down by glaciers that has the consistency of flour. Several meltwater streams rich with the particles, sometimes called suspended sediment, absorb and scatter sunlight in ways that turn water a milky blue-green hue. The water that flows into the bay from the Grewingk-Yalik Glacier Complex to the east carries sediment-infused waters that transform the appearance of the bay during the summer, raising questions about how much the influx of sediment affects the bay’s marine life.

Following liftoff, the Falcon 9 rocket will accelerate Dragon to approximately 17,500 mph. Once in orbit, the crew and SpaceX mission control in Hawthorne, California, will monitor a series of 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, Crew-10 will be welcomed aboard the station by the seven-member crew of Expedition 72 and conduct a short handover period on science and maintenance activities with the departing Crew-9 crew members. Then, NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Roscosmos cosmonaut Aleksandr Gorbunov will undock from the space station and return to Earth. Ahead of Crew-9 return, mission teams will review weather conditions at the splashdown sites off the coast of Florida prior to departure from station.

Crew-10 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. The crew is scheduled to conduct material flammability tests for future spacecraft designs, engage with students via ham radio and use its existing hardware to test a backup lunar navigation solution, and participate in an integrated study to better understand physiological and psychological changes to the human body to provide valuable insights for future deep space missions.

These are just a few of the more than 200 scientific experiments and technology demonstrations taking place during the mission.

While aboard the orbiting laboratory, Crew-10 will welcome a Soyuz spacecraft with three new crew members, including NASA astronaut Jonny Kim, and they will bid farewell to the Soyuz carrying NASA astronaut Don Pettit. The crew also is expected to see the arrival of the SpaceX Dragon, Roscosmos Progress, and Northrop Grumman’s Cygnus cargo spacecraft, as well as the short-duration private Axiom Mission 4 crew.

The cadre will fly aboard the SpaceX Dragon spacecraft, named Endurance, which previously flew NASA’s SpaceX Crew-3, Crew-5, and Crew-7 missions.

Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 24 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 benefits people on Earth and paves the way for future long-duration missions to the Moon and beyond through NASA’s Artemis missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

As NASA continues to enable a sustainable, cost-effective commercial space economy, the agency is seeking partnership proposals for the operations, sustaining engineering, and utilization of Astrobee, a free-flying robotic system aboard the International Space Station.

The Announcement for Partnership Proposal contains instructions and criteria for transferring responsibility of the Astrobee system to a commercial provider. Submissions are due to NASA by Friday, March 21.

Astrobee has operated aboard the space station since 2019, working autonomously or managed by flight controllers or researchers on the ground. Technology like the Astrobee system can help astronauts with routine duties, like inventory or documentation, freeing up time for complex work and additional experiments.

The Astrobee system includes three cube-shaped robots aboard the space station, software, and a docking station for recharging. On the ground, three robots function as flight spares and are used for software and maintenance testing. The system is an important technology demonstration and science, technology, engineering, and mathematics outreach platform.

The robots can fly freely through the station’s microgravity environment, with cameras and sensors to help guide them. Their perching arms can grasp station handrails or grab and hold items. Past experiments involving the Astrobee robots include testing mechanical adhesive technology, mapping the station, and identifying potential life support system issues.

“Astrobee has been a beacon for robotic and autonomous research in space for many years, working with academia and industry partners across our country and internationally,” said Eugene Tu, center director at NASA’s Ames Research Center in California’s Silicon Valley, which led the Astrobee project. “We’re excited about the opportunity to continue this mission with a commercial partner.”

As part of the agreement, the commercial partner will provide ground-based testing, equipment, and lab space as needed. The partner will be responsible for the Astrobee system through the end of the space station’s operational life. The commercial partner also will provide milestone objectives and ensure the continued development of Astrobee technology to support the future of commercial space.

The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth orbit economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human exploration of Mars.

Redshift Wranglers Reach Remarkable Milestones

Redshift Wranglers Reach Remarkable Milestones

A cartoon astronaut wearing a cowboy hat stands against a background of a deep-space galaxy field. The astronaut is holding a lasso that encircles a colorful spiral galaxy icon, which is connected to a zoomed-in spectral graph with highlighted peaks. The background features numerous stars and galaxies.
At Redshift Wrangler, anyone with a smartphone or laptop can help clock the expansion of the universe using light from distant galaxies.

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.
