Spacewalk preparations are under way at the International Space Station as two cosmonauts get ready for the first of three spacewalks set to begin on Tuesday. The rest of the Expedition 69 crew is cleaning up following the departure of a U.S. cargo craft while also working on a pair of Extravehicular Mobility Units (EMUs), or spacesuits.

Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are set to begin their second spacewalk together at 9:30 p.m. EDT on Tuesday. The duo spent Monday reviewing the tasks required to move a radiator from the Rassvet module to the Nauka science module during the planned six-hour and 40-minute excursion. Prokopyev and Petelin also set up their spacewalking tools, installed components on their Orlan spacesuits, and organized the Poisk module’s airlock where they will exit the station.

Roscosmos Flight Engineer Andrey Fedyaev will assist the spacewalkers in and out of their spacesuits on Tuesday and command the European robotic arm to maneuver the radiator and attach it to Nauka. NASA TV begins its live spacewalk coverage at 9 p.m. on Tuesday on the agency’s app and website.

Two NASA Flight Engineers spent Monday cleaning up after the SpaceX Dragon cargo craft departed the orbital outpost on Saturday returning 4,300 pounds of science experiments and station hardware back to Earth for analysis. Astronauts Woody Hoburg and Frank Rubio cleaned and stowed biology hardware housing samples that were shipped back to Earth aboard Dragon. Those samples and others will now be examined by scientists to understand how the human body adapts to living and working in weightlessness.

The NASA duo also partnered up with UAE (United Arab Emirates) astronaut Sultan Alneyadi loading another U.S. resupply ship ahead of its departure at the end of the week. The three flight engineers are packing trash and other discarded gear inside the Northrop Grumman Cygnus space freighter before it leaves the station later this week. Alneyadi will be on duty that morning monitoring Cygnus as mission controllers on the ground command the Canadarm2 robotic arm to release the spacecraft from the Unity module’s Earth-facing port. Cygnus will then reenter Earth’s atmosphere above the Pacific Ocean for a fiery, but safe demise.

Finally, Alneyadi and NASA Flight Engineer Stephen Bowen worked together resizing a pair of EMUs in the Quest airlock. The two astronauts are getting the U.S. spacesuits ready for an upcoming spacewalk to continue upgrading the station’s power generation capability.

This image shows a sequence of snapshots taken about 3 seconds apart. Gel samples from the investigation are returning to Earth for further analysis on the SpaceX CRS-27 cargo Dragon spacecraft.

SpaceX’s uncrewed Dragon cargo spacecraft splashed down at 4:58 p.m. EDT Saturday, April 15, off the coast of Tampa, Florida, marking the return of the company’s 27th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft carried approximately 4,300 pounds of valuable scientific experiments and other cargo back to Earth.

Some of the scientific investigations that Dragon is carrying include:

  • Space tomato harvest: Samples from the Pick-and-Eat Salad-Crop Productivity, Nutritional Value, and Acceptability to Supplement the International Space Station Food System (Veg-05) experiment will be returning to Earth for analysis. Astronauts grew dwarf tomatoes in the station’s Veggie miniature greenhouse and performed three harvests at 90, 97, and 104 days. They froze tomatoes, water samples, and swabs of the growth hardware to examine the effects of light quality and fertilizer on fruit production, microbial safety, and nutritional value. The ability to grow plants in space for fresh food and an improved crew living experience is important for future long-duration missions. The hardware could be adapted for use on Earth to provide fresh produce for those without access to gardens and as horticultural therapy for older people and people with disabilities.
  • Growing higher quality crystals: Hicari, an investigation from JAXA (Japan Aerospace Exploration Agency), tested a growth method and produced crystals of a silicon-germanium (SiGe) semiconductor using the Japanese Experiment Module-Gradient Heating Furnace (JEM-GHF). This crystal growth method could support development of more efficient solar cells and semiconductor-based electronics. The space-produced crystals are returning to Earth for analysis.
  • Analyzing aging arteries: Astronauts can experience accelerated arterial wall stiffening and thickening after six months in space, and a daily session of aerobic exercise alone may not be sufficient to counteract these effects. Vascular Aging, an investigation from CSA (Canadian Space Agency), monitors these changes using artery ultrasounds, blood samples, glucose tolerance tests, and wearable sensors. Results could help identify and assess risk to astronaut cardiovascular health and point to mechanisms for reducing that risk. For the aging population on Earth, understanding the mechanisms behind arterial stiffness could provide insight to guide prevention and treatment. Blood samples collected for the investigation are returning to Earth for analysis.
  • Fire safety: Solid Fuel Ignition and Extinction – Growth and Extinction Limit (SoFIE-Gel) studies burning in microgravity, including how fuel temperature affects material flammability. The investigation could improve safety of crew members on future missions by increasing understanding of early fire growth behavior, informing selection of fire-resistant spacecraft cabin materials, validating flammability models, and helping to determine optimal fire suppression techniques. Studying flames in space without the complications of buoyancy also helps improve computer models of combustion for terrestrial applications. Gel samples from the investigation are returning to Earth for further analysis.

NASA and SpaceX officials have given the “go” for the science- and cargo-packed Dragon cargo craft to undock from the International Space Station and return to Earth.  While the Expedition 69 crew finalizes Dragon cargo operations, preparations are still underway for a busy period of spacewalks set to begin on Tuesday.

An array of experiment hardware and research samples will return to Earth for analysis after Dragon undocks from the Harmony module’s forward port at 11:05 a.m. EDT on Saturday. Dragon will parachute to a splash down off the coast of Florida several hours later where support personnel from NASA and SpaceX will retrieve the vehicle. The 4,300 pounds of return cargo packed inside Dragon will then be extracted at NASA’s Kennedy Space Center, where the completed research and station hardware will be shipped to scientists and engineers around the world for investigation and examination.

NASA Flight Engineer Frank Rubio is wrapping up one final space biology study today, preparing scientific samples for observation back on Earth so researchers can understand how the human body adjusts to living long-term in microgravity. Stephen Bowen and Woody Hoburg, both from NASA, are also stowing a variety of research samples inside portable science freezers that can be launched into space, installed on the station, then returned inside the Dragon spacecraft.

Other science experiments are still ongoing aboard the orbiting outpost, including a cardiac study exploring ways to offset microgravity’s effect on heart cells and tissues. UAE (United Arab Emirates) Flight Engineer Sultan Alneyadi spent Friday morning in the Kibo laboratory module treating samples for the Engineered Heart Tissues-2 experiment. Using Kibo’s Life Sciences Glovebox, Alneyadi conducted the research operations that may help doctors treat, as well as prevent, space-caused heart conditions and Earth-bound cardiac disorders.

The orbital residents are also gearing up for several spacewalks to move hardware outside the space station. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin, both Roscosmos cosmonauts, will work over three spacewalks, the first beginning at 8:30 p.m. on Tuesday, to move a radiator and an experiment airlock from the Rassvet module to the Nauka science module. The duo spent Friday organizing their spacewalk tools and practicing their external maneuvers on a computer.

Roscosmos Flight Engineer Andrey Fedyaev began Friday attaching a sensor cap to himself then simulating piloting a spacecraft on a computer for a study exploring futuristic, piloting techniques on planetary missions. Afterward, he tested laptop computers inside the Zvezda service module then powered down Earth observation hardware in the Harmony module.

Three Expedition 69 crewmates are relaxing today after relocating their Soyuz crew ship to another port. Meanwhile, the other four International Space Station residents continued a variety of space research while maintaining orbital lab systems. Axiom Space also announced its second private mission to the orbital outpost.

NASA Flight Engineer Frank Rubio took a 37-minute ride inside the Soyuz MS-23 crew ship Thursday morning alongside Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The trio undocked from the Poisk module at 4:45 a.m. EDT and docked to the Prichal docking module, on the opposite side of the station, at 5:22 a.m. The relocation maneuver opens up Poisk’s airlock for a series of upcoming spacewalks in Orlan spacesuits and frees its docking port for the ISS Progress 84 resupply mission.

After a couple of hours of pressure and leak checks, the Soyuz and Prichal hatches opened with assistance from Roscosmos Flight Engineer Andrey Fedyaev. Rubio, Prokopyev, and Petelin then reentered the station, completed some Soyuz closeout tasks, and went to sleep early. They will be back on duty Friday for ongoing microgravity research and upcoming mission preparations.

Two NASA astronauts spent Thursday continuing their research into how living long-term in weightlessness changes the human body. NASA Flight Engineers Stephen Bowen and Woody Hoburg have been teaming up for the biology study before its return to Earth aboard the SpaceX Dragon resupply ship later this month. Scientists on the ground will use the observations to learn how to counteract space-caused symptoms and keep astronauts healthy as NASA prepares for human missions to the Moon, Mars, and beyond.

UAE (United Arab Emirates) Flight Engineer Sultan Alneyadi spent his day on a pair of different experiments studying both space physics and biotechnology. Alneyadi first swapped sample hardware inside the Materials Science Laboratory‘s low gradient furnace that supports research into new applications for existing materials or new and improved materials. Afterward, the UAE astronaut peered through a microscope at protein crystals for the Monoclonal Antibodies study that may improve the development of drugs on Earth.

Fedyaev, who earlier assisted his crewmates during their Soyuz relocation, worked on ventilation maintenance inside the Zvezda service module. He ended his day inside the Nauka multipurpose laboratory module inspecting and photographing cables.

Axiom Space announced its next private astronaut mission to the space station today. The Axiom-2 crew is, retired NASA astronaut and Mission Commander Peggy Whitson, Pilot John Shoffner, and Mission Specialists Ali Alqarni and Rayyanah Barnawi, all three first-time space flyers. Axiom-2 is targeting a launch to the station no earlier than 10:43 p.m. EDT on May 8 aboard a SpaceX Crew Dragon spacecraft.
