Life After Microgravity: Astronauts Reflect on Post-Flight Recovery 

NASA News - 14 hours 24 min ago

Space changes you. It strengthens some muscles, weakens others, shifts fluids within your body, and realigns your sense of balance. NASA’s Human Research Program works to understand—and sometimes even counter—those changes so astronauts can thrive on future deep space missions.

Astronauts aboard the International Space Station work out roughly two hours a day to protect bone density, muscle strength and the cardiovascular system, but the longer they are in microgravity, the harder it can be for the brain and body to readapt to gravity’s pull. After months in orbit, returning astronauts often describe Earth as heavy, loud, and strangely still. Some reacclimate within days, while other astronauts take longer to fully recover.

Adjusting to Gravity

The crew of NASA’s SpaceX Crew-7 mission— NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov—landed in March 2024 after nearly 200 days in space. One of the first tests volunteer crew members completed was walking with their eyes open and then closed.  

“With eyes closed, it was almost impossible to walk in a straight line,” Mogensen said. In space, vision is the primary way astronauts orient themselves, but back on Earth, the brain must relearn how to use inner-ear balance signals. Moghbeli joked her first attempt at the exercise looked like “a nice tap dance.”   

“I felt very wobbly for the first two days,” Moghbeli said. “My neck was very tired from holding up my head.” She added that, overall, her body readapted to gravity quickly.  

Astronauts each recover on their own timetable and may encounter different challenges. Mogensen said his coordination took time to return. Furukawa noted that he could not look down without feeling nauseated. “Day by day, I recovered and got more stable,” he said.

NASA astronaut Loral O’Hara returned in April 2024 after 204 days in space. She said she felt almost completely back to normal a week after returning to Earth. O’Hara added that her prior experience as an ocean engineer gave her insight into space missions. “Having those small teams in the field working with a team somewhere else back on shore with more resources is a good analog for the space station and all the missions we’re hoping to do in the future,” she said. 

NASA astronaut Nichole Ayers, who flew her first space mission with NASA’s SpaceX Crew-10, noted that the brain quickly adapts to weightlessness by tuning out the vestibular system, which controls balance. “Then, within days of being back on Earth, it remembers again—it’s amazing how fast the body readjusts,” she said.

When NASA astronaut Frank Rubio landed in Kazakhstan in September 2023, he had just completed a record 371-day mission—the longest single U.S. spaceflight.  

Rubio said his body adjusted to gravity right away, though his feet and lower back were sore after more than a year without weight on them. Thanks to consistent workouts, Rubio said he felt mostly recovered within a couple of weeks.  

Mentally, extending his mission from six months to a year was a challenge. “It was a mixed emotional roller coaster,” he said, but regular video calls with family kept him grounded. “It was almost overwhelming how much love and support we received.” 

Crew-8 astronauts Matt Dominick, Jeanette Epps, Michael Barratt, and cosmonaut Alexander Grebenkin splashed down in October 2024 after 235 days on station. Dominick found sitting on hard surfaces uncomfortable at first. Epps felt the heaviness of Earth immediately. “You have to move and exercise every day, regardless of how exhausted you feel,” she said.  

Barratt, veteran astronaut and board certified in internal and aerospace medicine, explained that recovery differs for each crew member, and that every return teaches NASA something new. 

Still a Challenge, Even for Space Veterans

Veteran NASA astronauts Suni Williams and Butch Wilmore returned from a nine-month mission with Crew-9 in early 2025. Despite her extensive spaceflight experience, Williams said re-adapting to gravity can still be tough. “The weight and heaviness of things is surprising,” she said. Like others, she pushed herself to move daily to regain strength and balance.

NASA astronaut Don Pettit, also a veteran flyer, came home in April 2025 after 220 days on the space station. At 70 years old, he is NASA’s oldest active astronaut—but experience did not make gravity gentler.  During landing, he says he was kept busy, “emptying the contents of my stomach onto the steppes of Kazakhstan.” Microgravity had eased the aches in his joints and muscles, but Earth’s pull brought them back all at once.  

Pettit said his recovery felt similar to earlier missions. “I still feel like a little kid inside,” he said. The hardest part, he explained, isn’t regaining strength in big muscle groups, but retraining the small, often-overlooked muscles unused in space. “It’s a learning process to get used to gravity again.”  

Recovery happens day by day—with help from exercise, support systems, and a little humor. No matter how long an astronaut is in space, every journey back to Earth is unique. 

The Human Research Program help scientists understand how spaceflight environments affect astronaut health and performance and informs strategies to keep crews healthy for future missions to the Moon, Mars, and beyond. The program studies astronauts before, during, and after spaceflight to learn how the human body adapts to living and working in space. It also collects data through Earth-based analog missions that can help keep astronauts safer for future space exploration.  

To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, for example, its scientists conduct bedrest studies – asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle.  Lying in this position tricks the body into responding as it would if the body was in space which allows scientists to trial interventions to hopefully counter some of microgravity’s effects.  Such studies, through led by NASA, occur at the German Aerospace Center’s Cologne campus at a facility called :envihab – a combination of “environment” and “habitat.”  

Additional Earth-based insights come from the Crew Health and Performance Exploration Analog (CHAPEA) and the Human Exploration Research Analog (HERA) at NASA’s Johnson Space Center in Houston. Both analogs recreate the remote conditions and scenarios of deep space exploration here on Earth with volunteer crews who agree to live and work in the isolation of ground-based habitats and endure challenges like delayed communication that simulates the type of interactions that will occur during deep space journeys to and from Mars. Findings from these ground-based missions and others will help NASA refine its future interventions, strategies, and protocols for astronauts in space. 

NASA and its partners have supported humans continuously living and working in space since November 2000. After nearly 25 years of continuous human presence, the space station remains the sole space-based proving ground for training and research for deep space missions, enabling NASA’s Artemis campaign, lunar exploration, and future Mars missions.

Perseverance Meets the Megabreccia

2 min read

Perseverance Meets the Megabreccia NASA’s Mars Perseverance rover acquired this image of the “Scotiafjellet” workspace on Aug. 31, 2025, using its onboard Left Navigation Camera (Navcam). The camera is located high on the rover’s mast and aids in driving. This image was acquired on Sol 1610, or Martian day 1,610 of the Mars 2020 mission, at the local mean solar time of 14:52:20. NASA/JPL-Caltech

Written by By Henry Manelski, Ph.D. student at Purdue University

Last week, the Perseverance rover began an exciting new journey. Driving northwest of the Soroya ridge, Perseverance entered an area filled with a diverse range of boulders that the science team believes could hold clues to Mars’ early history. The terrain we are exploring is known as megabreccia: a chaotic mixture of broken rock fragments likely produced during ancient asteroid impacts. Some blocks may have originated in the gargantuan Isidis impact event, which created a 1,200-mile-wide crater (about 1,930 kilometers) just east of Jezero. Studying megabreccia could help us link Jezero’s geology to the wider region around Isidis Basin, tying local observations to Mars’ global history. 

The rover is now beginning a systematic exploration of these rocks, starting at Scotiafjellet. If they are truly megabreccia, they could contain pieces of deep crustal material, offering a rare glimpse into Mars’ interior. These rocks likely predate the deltaic and volcanic deposits we explored earlier in Jezero Crater, making them some of the oldest accessible rocks Perseverance will ever encounter. They may therefore reveal to what extent water was present on ancient Mars — a key question as we continue our search for signs of past life on the Red Planet. In short, by venturing into this jumbled terrain, Perseverance is giving us a front-row seat to the earliest chapters of Mars’ story.

Metals Are Critical To Life - We Should Screen Exoplanets For Them

Universe Today - Mon, 09/08/2025 - 7:04pm

Life is complicated, and not just in a philosophical sense. But one simple thing we know about life is that it requires energy, and to get that energy it needs certain fundamental elements. A new paper in preprint on arXiv from Giovanni Covone and Donato Giovannelli from the University of Naples discusses how we might use that constraint to narrow our search for stars and planets that could potentially harbor life. To put it simply, if it doesn’t have many of the constituent parts of the “building blocks” of life, then life probably doesn't exist there.

NASA, Northrop Grumman, and SpaceX are targeting no earlier than 6:11 p.m. EDT, Sunday, Sept. 14, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. The mission is known as NASA’s Northrop Grumman Commercial Resupply Services 23, or Northrop Grumman CRS-23.

Watch the agency’s launch and arrival coverage on NASA+, Amazon Prime, and more. Learn how to watch NASA content through a variety of platforms, including social media.

Filled with more than 11,000 pounds of supplies, the Northrop Grumman Cygnus XL spacecraft, carried on a SpaceX Falcon 9 rocket, will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This mission will be the first flight of the Cygnus XL, the larger, more cargo-capable version of the company’s solar-powered spacecraft.

Following arrival, astronauts aboard the space station will use the Canadarm2 to grapple Cygnus XL on Wednesday, Sept. 17, before robotically installing the spacecraft to the Unity module’s Earth-facing port for cargo unloading.

Highlights of space station research and technology demonstrations, facilitated by delivery aboard this Cygnus XL, include materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. The spacecraft also will deliver a specialized UV light system to prevent the growth of microbe communities that form in water systems and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.

Media interested in speaking to a science subject matter expert should contact Sandra Jones at: sandra.p.jones@nasa.gov. A copy of NASA’s media accreditation policy is available on the agency’s website.

The Cygnus XL spacecraft is scheduled to remain at the orbiting laboratory until March before it departs and burns up in the Earth’s atmosphere. Northrop Grumman has named the spacecraft the S.S. William “Willie” McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.

NASA will host a media teleconference at 11 a.m. EDT Wednesday, Sept. 10, to discuss the analysis of a rock sampled by the agency’s Perseverance Mars rover last year, which is the subject of a forthcoming science paper.

The sample, called “Sapphire Canyon,” was collected in July 2024 from a set of rocky outcrops on the edges of Neretva Vallis, a river valley carved by water rushing into Jezero Crater long ago.

Audio and visuals of the call will stream on the agency’s website at:

https://www.nasa.gov/live

Participants in the teleconference include:

  • Acting NASA Administrator Sean Duffy
  • Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington
  • Lindsay Hays, Senior Scientist for Mars Exploration, Planetary Science Division, NASA Headquarters
  • Katie Stack Morgan, Perseverance Project Scientist, NASA’s Jet Propulsion Laboratory in Southern California
  • Joel Hurowitz, planetary scientist, Stony Brook University, New York

Since landing in the Red Planet’s Jezero Crater in February 2021, Perseverance has collected 30 samples. The rover still has six empty sample tubes to fill, and it continues to collect detailed information about geologic targets that it hasn’t sampled by using its abrasion tool. Among the rover’s science instruments is a weather station that provides environmental information for future human missions, as well as swatches of spacesuit material so that NASA can study how it fares on Mars.

Managed for NASA by Caltech, JPL built and manages operations of the Perseverance rover on behalf of the agency’s Science Mission Directorate as part of NASA’s Mars Exploration Program portfolio.
