The Soyuz MS-21 rocket lifts off on time from Kazakhstan carrying three cosmonauts to the space station.
Roscosmos cosmonaut Oleg Artemyev, Denis Matveev, and Sergey Korsakov are safely in orbit on the Soyuz MS-21 spacecraft after launching at 11:55 a.m. EDT from the Baikonur Cosmodrome in Kazakhstan (8:55 p.m. Baikonur time).
The Soyuz will dock to the station’s Prichal module at 3:05 p.m. About two hours after docking, hatches between the Soyuz and the station will open.
NASA TV coverage of docking will begin at 2:15 p.m. on NASA Television, the NASA app and the agency’s website.

NASA TV coverage now is underway for the launch of a crewed Russian Soyuz spacecraft to the International Space Station with Roscosmos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov. The Soyuz MS-21 spacecraft will launch from the Baikonur Cosmodrome in Kazakhstan at 11:55 a.m. EDT (8:55 p.m. Baikonur time). Launch and docking activities will air live on NASA Television, the NASA app, and the agency’s website.
After a three-hour and 10-minute flight, the Soyuz will dock to the station’s Prichal module at 3:05 p.m. About two hours after docking, hatches between the Soyuz and the station will open.
Station Gets Ready for New Crew and Next Spacewalk

A new trio awaits its launch to join the Expedition 66 crew on Friday while two astronauts are preparing for next week’s spacewalk. Human research rounded out the science schedule aboard the International Space Station on Thursday.
Three cosmonauts are counting down to their lift off aboard the Soyuz MS-21 crew ship at 11:55 a.m. EDT on Friday from the Baikonur Cosmodrome in Kazakhstan. Soyuz Commander Oleg Artemyev will lead first-time space-flyers Denis Matveev and Sergey Korsakov on a three-hour and 10-minute ride to the Prichal module where they will dock beginning a six-and-a-half-month mission aboard the station. NASA TV, on the app and the website, will begin its live mission coverage of the crew launch and docking activities at 11:15 a.m. on Friday.
Meanwhile, a second spacewalk is scheduled for Wednesday, March 23, for more upgrades at the orbiting lab. Flight Engineers Raja Chari of NASA and Matthias Maurer of ESA (European Space Agency) will set their spacesuits to battery power at 8:50 a.m. signifying the start of their spacewalk. The duo will spend about six-and-a-half-hours installing new thermal system and electronics components. NASA TV will begin its live spacewalk coverage at 7:30 a.m. on Wednesday.
The spacewalking pair was joined Thursday afternoon by NASA Flight Engineers Kayla Barron and Tom Marshburn reviewing robotics procedures necessary to support the astronauts during next week’s external maintenance job. Chari and Maurer also spent Thursday organizing their spacewalking tools and resizing their U.S. spacesuits.
Commander Anton Shkaplerov and Flight Engineer Pyotr Dubrov continued evaluating a specialized suit, the lower body negative pressure suit, for its ability to counteract the effects of weightlessness on the human body. Doctors are studying the suit’s ability to offset space-caused head and eye pressure by drawing fluids toward the legs and feet while expanding veins and tissues.
Next Crew Launch Set for Friday Following Tuesday’s Spacewalk

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.
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 Complete Spacewalk for Solar Array Work

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.
