NASA/JAXA SPACEWALK AT ISS, ?, 2021, Earth orbit

Update, August 23, 3:00 pm ET:  NASA just announced that the spacewalk has been postponed due to a “minor medical issue involving Vande Hei. This issue is not a medical emergency.” NASA still deciding when it will take place, but will be after SpX-23 and the Russian spacewalks.

Vande Hei later tweeted that the problem is a pinched nerve in his neck.

Thanks for everyone’s concern. I have a pinched nerve in my neck that caused us to reschedule today’s spacewalk. The support from family, friends, and NASA leadership has been fantastic. I’m looking forward to installing this IROSA Mod kit. Today just wasn't the right day. https://t.co/srGT9GQfCm

Original entry: NASA astronaut Mark Vande Hei and JAXA astronaut Aki Hoshide will conduct a spacewalk at the International Space Station (ISS) on August 24, 2021 beginning at approximately 8:30 am ET.  The spacewalk is expected to last about 6 hours and 3o minutes.

NASA TV coverage begins at 7:00 am ET.

Vande Hei and Hoshide are scheduled to install a “modification kit” that will enable installation of an iROSA solar array during a subsequent spacewalk. They will also replace a device that measures the electrical charging potential of the arrays and associated surfaces in its vicinity.
