Here is the latest episode in NASA’s Space to Ground weekly report on activities related to the International Space Station:
** Soyuz MS-21 manual docking – SciNews
The Soyuz MS-21 spacecraft was docked to the Prichal module of the International Space Station (ISS) on 18 March 2022, at 19:12 UTC (22:12 MSK, 15:12 EDT). The Soyuz MS-21 spacecraft, Soyuz MS-21, with Roscosmos cosmonauts Oleg Artemyev, Denis Matveev and Sergey Korsakov, is scheduled for hatch opening at 21:30 UTC (17:30 EDT; 19 March, at 00:30 MSK).

** U.S. Spacewalk 79 Animation – March 14, 2022 – NASA Johnson
Expedition 66 NASA astronauts Kayla Barron and Raja Chari will step outside the International Space Station for a six-and-a-half hour spacewalk to conduct preparation work for upcoming solar array upgrades for the station’s 3A power channel. The current solar arrays which were designed for a 15-year service life are functioning well, but have begun to show signs of degradation, as expected. The first pair of solar arrays were deployed in December 2000 and have been powering the station for more than 20 years. The new ISS Roll-Out Solar Arrays (IROSAs) will be positioned in front of six of the current arrays, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts. Installation of the first two solar array upgrades were completed during spacewalks on June 20, 2021 and June 25, 2021.
** NASA astronauts begin spacewalk to prep ISS for solar array upgrades – VideoFromSpace – March 15th EVA
Spacewalking Expedition 66 astronauts Kayla Barron and Raja Chari have begun “work for solar array upgrades for the station’s 3A power channel,” according to NASA.
** Spacewalk at the Space Station with NASA Astronauts Kayla Barron and Raja Chari – NASA
NASA astronauts Kayla Barron and Raja Chari conduct a spacewalk at the International Space Station (ISS) to assemble and install brackets and struts kits for upcoming solar array upgrades. The new ISS Roll-Out Solar Arrays, or iROSAs, will increase the space station’s total available power. So far, two of six iROSAs have been deployed on the station with four additional arrays to be delivered. Barron will serve as extravehicular crewmember 1 (EV 1) and will wear a suit with red stripes. Chari will serve as extravehicular crewmember 2 (EV 2) and will wear a suit with no stripes. The spacewalk will be the second of Barron’s career and the first for Chari.
** U.S. Spacewalk 80 Animation – March 14, 2022 – NASA Johnson
On March 23, two Expedition 66 astronauts will step outside the International Space Station for a planned six-and-a-half hour spacewalk to replace hoses and other hardware for one of the radiator beam calve modules on the complex and to conduct other upgrades to station hardware.
** Expedition 66 Astronaut Kayla Barron Answers U.S. Navy, Student Questions – March 16, 2022 – NASA Video
Aboard the International Space Station, Expedition 66 Flight Engineer Kayla Barron of NASA discussed life and work aboard the orbital outpost during an in-flight event March 16 with students in the U.S. Navy. Barron graduated from the U.S. Naval Academy and was a member of the first class of women commissioned into the submarine community. She is now in the midst of a planned six-month 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.
** ISS National Lab Sustainability Challenge: Viewer’s Choice Introduction – ISS National Lab – YouTube
We are excited to officially announce the ISS National Lab Sustainability Challenge: Viewer’s Choice presentation and are featuring a week of sustainability-related content leading up to the virtual event on March 25. Beginning on March 14, the finalists’ videos will be featured on the ISS National Lab’s YouTube channel. Viewers will have the opportunity to vote on submissions. Voting will conclude on March 21, and the winning team will be announced during the virtual event. Vote HERE to cast your vote for the winning Viewer’s Choice presentation! https://bit.ly/issnlscvote
Don’t miss the event! 2022 ISS National Lab Sustainability Challenge: Beyond Plastics Virtual Event 3/25 at 1pm EDT Register here: https://bit.ly/issnlscregister
The Sustainability Challenge is an open solicitation for U.S.-based entities to propose flight projects that leverage the space station to tackle plastics waste and enable scientific or technological advancements that improve Earth’s environment. The virtual event on March 25, 2022, will feature finalists’ recorded presentations and exciting guest speakers, culminating with an award ceremony recognizing the top ranked finalists. Following the event, finalists will be invited to submit a Full Proposal for a flight project leveraging the ISS National Lab, and the Final Determination for the selected team will be announced at the 2022 ISS Research and Development Conference July 25-28 in Washington, D.C.

Currently, live views from the ISS are streaming from an external camera mounted on the ISS module called Node 2. Node 2 is located on the forward part of the ISS. The camera is looking forward at an angle so that the International Docking Adapter 2 (IDA2) is visible. If the Node 2 camera is not available due to operational considerations for a longer period of time, a continuous loop of recorded HDEV imagery will be displayed. The loop will have “Previously Recorded” on the image to distinguish it from the live stream from the Node 2 camera. After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life. Thank You to all who shared in experiencing and using the HDEV views of Earth from the ISS to make HDEV so much more than a Technology Demonstration Payload!
