SUMMARY:U.S. ISS Spacewalk 97
DESCRIPTION:During U.S. spacewalk 97\, two astronauts will replace a Space-to-Ground antenna on the orbital complex. The antenna is a critical communication system NASA uses to transmit data and high‑speed communication between the Mission Control Center in Houston and the space station. This will be the 282nd spacewalk conducted in support of space station assembly\, maintenance\, and upgrades.

SUMMARY:U.S. ISS Spacewalk 96
DESCRIPTION:NASA astronauts Jessica Meir and Anil Menon will exit the Quest airlock to install hardware that will modify the station’s 3B power channel and prepare it for the future installation of an International Space Station Roll-Out Solar Array (IROSA). The solar array\, scheduled for delivery later this year\, will be the seventh IROSA and will provide additional power to support critical station operations\, including its safe and controlled deorbit. \nWatch NASA’s live coverage of U.S. spacewalk 96 beginning at 7 a.m. The spacewalk is expected to start at 8:35 a.m. and last about six and a half hours. \nThis spacewalk will be the sixth for Meir and the first for Menon. Meir will serve as spacewalk crew member 1 and will wear a suit with red stripes. Menon will serve as crew member 2 and will wear an unmarked suit.
