The International Space Station is set to welcome three new crewmates who are set to launch on Friday and arrive just over three hours later. In the meantime, the seven-member Expedition 66 crew turned its attention to science duties following Tuesday’s successful spacewalk.

The next crew ship to launch toward the orbiting lab has rolled out and now stands at the Baikonur Cosmodrome launch pad in Kazakhstan. The Soyuz MS-21 spacecraft is counting down to lift off on Friday at 11:55 a.m. EDT. It will carry three cosmonauts on a three-hour and 10-minute ride to the station where it will dock to the Prichal module. Veteran cosmonaut Oleg Artemyev, with first-time station visitors Denis Matveev and Sergey Korsakov, will open the hatch about an two-and-a-half hours later and begin a six-and-a-half-month mission aboard the space station. NASA TV, on the app and the website, will begin its live launch coverage at 11:15 a.m. on Friday.

Two NASA astronauts, Kayla Barron and Raja Chari, had a light schedule on Wednesday following Tuesday’s six-hour and 54-minute spacewalk to set up the station for its next roll-out solar array. The pair started the day with standard post-spacewalk medical exams looking at their hands, ears, blood pressure, and temperature. Barron then worked late in the afternoon in the Kibo laboratory module setting up the Confocal Microscope that looks at biological samples using spatial filtering techniques. Chari wrapped up his day charging the U.S. spacesuit’s lithium-ion batteries.

Flight Engineers Tom Marshburn of NASA and Matthias Maurer of ESA (European Space Agency) teamed up for a muscle study taking place in the Columbus laboratory module on Wednesday. The astronauts took turns measuring each other’s neck, back, and leg muscles to learn how microgravity affects their biochemical properties. NASA astronaut Mark Vande Hei serviced microbe samples growing inside a specialized incubator for the Space Biofilms study that could improve spacecraft safety and crew health.

In the station’s Russian segment, two cosmonauts, Commander Anton Shkaplerov and Flight Engineer Pyotr Dubrov, packed gear and prepared for their return to Earth on March 30. Shkaplerov will lead the ride home flanked by Dubrov and Vande Hei inside the Soyuz MS-19 crew ship. Vande Hei surpassed NASA astronaut Scott Kelly’s single spaceflight record of 340 days on March 15 and will land in Kazakhstan with a NASA record-breaking 355 days in space.

NASA astronauts Kayla Barron and Raja Chari concluded their spacewalk at 3:06 p.m. EDT after 6 hours and 54 minutes in preparation for upcoming solar array installation.

Barron and Chari completed their major objectives for today to prepare the space station for upcoming solar array upgrades by assembling and installing modification kits. The duo built a support bracket onto which a future ISS roll out solar array (iROSA) will be mounted. So far, two of six iROSAs have been deployed on station with four additional arrays to be delivered. The arrays will ultimately augment six of the station’s eight power channels, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.

It was the 247th spacewalk in support of space station assembly, upgrades and maintenance, and was the first in Chari’s career and the second for Barron. Chari and Barron are in the midst of a planned six-month science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program.

Astronaut roles for the next spacewalk on March 23 will be confirmed soon. NASA TV coverage for the March 23 spacewalk will begin at 7:30 a.m. for a spacewalk expected to begin around 8:50am.

For the Wednesday, March 23, spacewalk, designated U.S. EVA 80, two astronauts will install hoses on a Radiator Beam Valve Module that routes ammonia through the station’s heat-rejecting radiators to keep systems at the proper temperature. The crew members also will install a power and data cable on the Columbus module’s Bartolomeo science platform, replace an external camera on the station’s truss, and conduct other upgrades to station hardware.Learn more about station activities by following the space station blog, @space_station and @ISS_Research on Twitter, as well as the ISS Facebook and ISS Instagram accounts.

Expedition 66 Flight Engineers Kayla Barron and Raja Chari of NASA began a spacewalk to assemble and install modification kits required for upcoming solar array upgrades on the International Space Station at 8:12 a.m. EDT.

Barron, designated extravehicular crew member 1 (EV1), is wearing a suit with red stripes. Chari, designated extravehicular crewmember 2 (EV 2), will wear a suit with no stripes. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.

Barron and Chari’s primary task will be to assemble and install modification kits required for upcoming solar array upgrades. The pair will install brackets and struts to support the future installation of an ISS Roll-Out Solar Array (iROSA).

Two Expedition 66 astronauts are in final preparations today for Tuesday’s spacewalk after mission managers gave the final go early Monday. NASA TV will broadcast a live briefing today at 2 p.m. EDT with International Space Station managers discussing the upcoming spacewalk activities.

The U.S. Quest airlock has been configured to host NASA Flight Engineers Kayla Barron and Raja Chari when they set their U.S. spacesuits to battery power on Tuesday at 8:05 a.m. signifying the start of a six-and-a-half-hour spacewalk. The duo will exit Quest then translate over to the Starboard-4 truss structure and install modification kits that will ready the space station for its third roll-out solar array. NASA TV, on the app and the website, will begins its live spacewalk broadcast on Tuesday at 6:30 a.m.

Barron and Chari started Monday readying their spacesuits and staging their spacewalk tools inside Quest. They were joined afterward by Flight Engineers Tom Marshburn of NASA and Matthias Maurer of ESA (European Space Agency) for a final procedures review and a conference with specialists on the ground. Marshburn and Maurer will help the spacewalkers in and out of their suits and monitor and guide them during the exterior maintenance job.

NASA Flight Engineer Mark Vande Hei focused on another upcoming external job as he set up a small satellite deployer inside the Kibo laboratory module on Monday. He placed the deployer inside Kibo’s airlock where it will be grappled by the Japanese robotic arm, placed in the vacuum of outer space, and pointed away from the station. Soon a set of CubeSats will be released into Earth orbit for a variety of educational and scientific research activities.

The two cosmonauts in the station’s Russian segment, Commander Anton Shkaplerov and Flight Engineer Pyotr Dubrov, continued studying the effectiveness of an antigravity suit that may offset the effects of living in space. Known as the lower body negative pressure suit, it has the ability to draw fluids that pool toward a crew member’s head down to the legs and feet expanding veins and tissues. This may prevent space-caused head pressure and vision issues as well as easing a human’s return to Earth’s gravity.
