NASA astronaut and microbiologist Kate Rubins retired Monday after 16 years with the agency. During her time with NASA, Rubins completed two long-duration missions aboard the International Space Station, logging 300 days in space and conducting four spacewalks.
 
“I want to extend my sincere gratitude to Kate for her dedication to the advancement of human spaceflight,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “She is leaving behind a legacy of excellence and inspiration, not only to our agency, but to the research and medical communities as well. Congratulations, Kate, on an extraordinary career.”
 
Rubins’ first mission to the orbiting laboratory began in July 2016, aboard the first test flight of the new Soyuz MS spacecraft. As part of Expedition 48/49, she contributed to more than 275 scientific experiments, including molecular and cellular biology research, and she was the first person to sequence DNA in space. Her work enabled significant advances with in-flight molecular diagnostics, long-duration cell culture, and the development of molecular biology tools and processes, such as handling and transferring small amounts of liquids in microgravity. Rubins also led the integration and deployment of biomedical hardware aboard the space station, supporting crew health and scientific research in space and on Earth.
 
She again launched in October 2020, aboard a Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan, taking part in Expedition 63/64. Alongside her crewmates, Rubins spent hundreds of hours working on new experiments and furthering research investigations conducted during her mission, including heart research and multiple microbiology studies. She also advanced her work on DNA sequencing in space, which could allow future astronauts to diagnose illness or identify microbes growing aboard the station or during future exploration missions.
 
“From her groundbreaking work in space to her leadership on the ground, Kate has brought passion and excellence to everything she’s done,” said Joe Acaba, chief of the Astronaut Office at NASA Johnson. “She’s been an incredible teammate and role model. We will miss her deeply, but her impact will continue to inspire.”
 
In addition to her flight assignments, Rubins served as acting deputy director of NASA’s Human Health and Performance Directorate, where she helped guide strategy for crew health and biomedical research. More recently, she contributed to developing next-generation lunar spacesuits, helping prepare for future Artemis missions to the Moon.
 
 
Before her selection as an astronaut in 2009, Rubins received a bachelor’s degree in molecular biology from the University of California, San Diego, and a doctorate in cancer biology from Stanford University Medical School’s Biochemistry Department and Microbiology and Immunology Department. After returning from her second space mission, Rubins commissioned as a major in the U.S. Army Reserve, serving as a microbiologist in the Medical Service Corps. She currently holds the role of innovation officer with the 75th U.S. Army Reserve Innovation Command’s MedBio Detachment, headquartered in Boston. 

A frequent keynote speaker at scientific, educational, and industry events on space biology, biomedical engineering, and human exploration, Rubins has advocated for NASA’s scientific and exploration missions. As she transitions from government service, she remains committed to advancing innovation at the intersection of biology, technology, and space.
 
“It has been the honor of a lifetime to live and work in space,” said Rubins. “I am grateful for the extraordinary advances at NASA, and it was a privilege to serve and contribute to something so meaningful. The mission of exploration continues, and I can’t wait to watch this nation do what once seemed impossible.”

The seven-member Expedition 73 crew is gearing up to welcome four new crewmates at the end of the week. Shortly after that another quartet that has been living and working aboard the International Space Station since March will return to Earth.

The SpaceX Falcon 9 rocket has rolled out to its launch pad at the Kennedy Space Center and is counting down to its launch of NASA’s SpaceX Crew-11 mission at 12:09 p.m. EDT on Thursday. NASA+ will begin its Crew-11 launch coverage beginning at 8 a.m. on Thursday.

Commander Zena Cardman and Pilot Mike Fincke, both NASA astronauts, and Mission Specialists Kimiya Yui of JAXA (Japan Aerospace Exploration Agency) and Oleg Platonov of Roscosmos will ride inside the Dragon spacecraft atop Falcon 9 for an automated, day-and-a-half long trip to the orbital outpost’s space-facing port on the Harmony module. Once there, the four Crew-11 members will join Expedition 73 beginning a seven-month research mission in low Earth orbit.

Following the new crew’s arrival, four Expedition 73 crew members representing NASA’s SpaceX Crew-10 mission will begin handing over their science and maintenance responsibilities in preparation for their departure about a week later. The homebound quartet has also been ramping up its packing duties loading science, cargo, and personal items inside the Dragon docked to Harmony’s forward port. Anne McClain will lead Nichole Ayers, both NASA astronauts, JAXA astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov for reentry into Earth’s atmosphere and a parachuted splashdown inside Dragon.

McClain, Ayers, and Onishi spent Monday in the Harmony module cleaning their crew quarters’ ventilation systems and airflow sensors. McClain also set up a sleeping bag inside Dragon that she will be using until her departure early next month. Ayers configured an extra sleep station in the Columbus laboratory module to accommodate the upcoming crew swap period. Onishi will now be sleeping in the Kibo laboratory module until he departs with his Crew-10 crewmates.

Peskov has also been preparing for his Dragon departure as he tested the lower body negative pressure suit. Roscosmos scientists are investigating the suit’s ability to counteract space-caused head and eye pressure and help crews adjust quicker to the return to Earth’s gravity. He also continued gathering his personal items and Roscosmos cargo for loading inside Dragon.

Roscosmos Flight Engineer Alexey Zubritsky started his day assisting Peskov with the experimental suit study then measured the vibrations the space station experiences while jogging on the Zvezda service module’s treadmill. Veteran cosmonaut Sergey Ryzhikov tested new freeze-dried food packs for their ease of use for both eating and drinking then set up Earth observation gear to photograph landmarks in the Pacific Ocean and across North America.

NASA’s SpaceX Crew-11 mission moved closer to launch, as the SpaceX Falcon 9 rocket and Dragon spacecraft slated to take the four-member crew to the International Space Station rolled to the pad and the crew participated in a dry dress rehearsal on Monday, July 28 at NASA’s Kennedy Space Center in Florida.

NASA astronauts Zena Cardman and Mike Fincke, along with JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui and Roscosmos cosmonaut Oleg Platonov, spent the day donning spacesuits and completing air leak checks inside the Neil A. Armstrong Operations and Checkout Building at NASA Kennedy. Once suited, the crew members boarded vehicles that drove them to Launch Complex 39A where they entered the SpaceX Dragon spacecraft that will take them to the space station.

Crew-11 is scheduled to launch to the space station no earlier than 12:09 p.m. EDT on Tuesday, July 31, for a long-duration mission.

Upon Crew-11’s arrival to the orbiting laboratory, NASA’s SpaceX Crew-10 crew members will help familiarize the new crew with ongoing science and station maintenance work, which supports a safer transition of operations aboard the space station. Following a brief handover and pending weather conditions, Crew-10, including NASA astronauts Anne McClain and Nichole Ayers, JAXA astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov, will board their SpaceX spacecraft and splashdown off the coast of California.

NASA’s Commercial Crew Program has delivered on its goal of safe, reliable, and cost-effective transportation to and from the International Space Station from the United States through a partnership with American private industry. This partnership is opening access to low Earth orbit and the International Space Station to more people, more science, and more commercial opportunities. For almost 25 years, people have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration of the Moon as we prepare for Mars.

Curiosity Blog, Sols 4611-4613: Scenic Overlook

A grayscale photo from the Martian surface shows rocky, uneven, light-gray terrain that slopes downward, away from the rover. Parts of the rover are visible in the bottom of the frame, and the downward slope extends from the bottom of the frame toward the top of the frame, with a ridge line tracing the descent.
NASA’s Mars rover Curiosity acquired this image, sitting on top of the distinctive ridge-and-hollow terrain of the boxwork-forming unit for a panoramic view, on July 24, 2025. Curiosity used its Right Navigation Camera on Sol 4609, or Martian day 4,609 of the Mars Science Laboratory mission, at 21:29:43 UTC.

Earth planning date: Friday, July 25, 2025

A 23-meter drive (about 75 feet) brought Curiosity to today’s planned “look-about” spot. The highlight of the plan will be the 360-degree Mastcam panorama that will document the ridge-and-hollow topography of the boxwork-forming unit we’ve been exploring, in addition to overlying stratigraphy in some of the nearby buttes. The right-angle ridge pattern is quite prominent in the HiRISE orbital imaging, which enabled us to plan for this stop. It has been 70 sols since the last panorama, and the rover has driven quite some distance in that time!

Additional detailed imaging was planned with the ChemCam remote imager (RMI) and Mastcam high-resolution M100: mosaics will cover the exposed strata underneath the ridge we’re planning to drive on (“Arequipa Airport”), two linear fractures, one parallel to the large ridge and one cross-cutting it (“Laguna de Salinas” and “Laguna Santa Rosa”), some troughs around a nearby light-toned float block (“Arubai”), and the Uyuni butte in the middle distance.

The bedrock texture here was a noticeable change from the previous workspace, with a knobbly oriented texture interspersed occasionally with platier exposures. Geochemical measurements were planned with the ChemCam LIBS to complement the auto-targeted post-drive AEGIS measurement: “La Coca” on a block that appeared to show unusual colors, and “El Algodón” on a knobbly textured chunk of bedrock. APXS geochemistry was planned with dust removal on the “Yura Tuff” knobbly target and without dust removal on the “Tipnis” target. MAHLI will also provide close-up imaging on the two APXS targets.

For the modern Martian environment, it’s still the cloudy season at Gale so we are planning several cloud-related activities. The Mastcam sky survey will measure abundances of atmospheric dust and water ice, whereas a special cloud altitude observation will include video of clouds and their shadows so that the altitudes and velocities of the clouds and related winds can be calculated. A separate short movie will search for dust lifting (dust devil) activity. Finally, the usual passive REMS and DAN observations will monitor the temperature, humidity, and neutron environment at Curiosity’s current location.
