Scheduled for Jun 15, 2023  #NASA #Astronaut #Spacewalk
NASA astronauts Steve Bowen and Warren "Woody" Hoburg are taking a spacewalk on Thursday, June 15, to add a new solar panel to the International Space Station.

Bowen and Hoburg are scheduled to install a second International Space Station Roll-Out Solar Array, or IROSA, on this spacewalk, after previously installing one on June 9. The new arrays will increase the power capacity of the orbiting laboratory.

The spacewalk is scheduled to begin at 8:55 a.m. EDT (1255 UTC) and last about six hours. This is Bowen's tenth spacewalk and the second for Hoburg.

Depressurization is underway.

(I won't be available for running commentary/pictures like I did on EVA-87 - on the road to Bonnaroo - so if anyone else is available that would be appreciated!)

US EVA-88: This will be the 8th spacewalk so far this year, the 2nd for Hoburg and the 10th for Bowen; he expects to move from 5th to 3rd on the list of world's most experienced spacewalkers, passing Drew Feustel's 61-hr 48-min mark just 1 hour 26 minutes into today's EVA

Spacewalk has officially begun - Hoburg and Bowen's suits are on internal battery power.

Hoburg is now carrying the iROSA away from its flight support equipment, and being flown via SSRMS over to the installation site on the 1B power channel.

Another total TDRS LOS with TDRS-Z (275) unavailable for 14 minutes. TDRS 8 is still communicating--S band only--via the Canberra DSN as recovery efforts on Guam obviously continue. These two EVAs are the only times I can remember IV duties being passed to the crew.

They are in orbital night, 1 min away from eclipse. Also there will be an 8 min data LOS. Will have voice for all but last 2 min of that.

I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

Another reference to "shaw SS" voice comms that did not work during the last TDRS LOS.  I noted in the last EVA I believe that is use of Russian ground stations via VHF. Can anyone confirm?

Another view of missing "panel".

Offline Bubbinski

The abnormality on the iROSA is not expected to affect electrical production. Deployment finished.

Flight control team is happy with array deployment. Astronauts ahead of schedule, finishing cleanup activities.

Both astronauts at the airlock, getting ready to finish things out after a work ahead task of retrieving a tool for a future EVA.

Spacewalk success 👏

Astronauts @Astro_Woody and Steve Bowen successfully installed a roll-out solar array after a 5hr and 35 minute spacewalk outside the @Space_Station.

Teams on the ground in Mission Control Houston helped guide them through the steps.

NASA Spacewalkers Finish Installing Roll-Out Solar Array

Expedition 69 Flight Engineers Woody Hoburg and Steve Bowen of NASA concluded their spacewalk at 2:17 p.m. EDT after 5 hours and 35 minutes.

Hoburg and Bowen completed their major objective to install an IROSA (International Space Station Roll-Out Solar Array) to augment power generation for the 1B power channel on the stationís starboard truss structure.

The new array is 60 feet long by 20 feet wide (18.2 meters by 6 meters) and is shading a little more than half of the original array, which is 112 feet long by 39 feet wide. Each new IROSA produces more than 20 kilowatts of electricity and together enable a 30% increase in power production over the stationís current arrays.

NASA and Boeing have a plan in place for a fourth set of roll-out arrays to further augment the International Space Stationís power supply. These arrays, which would be the seventh and eighth installed on space station, are targeted for delivery to the orbital outpost in 2025.

It was the 265th spacewalk in support of space station assembly, upgrades, and maintenance. The spacewalk marked the second for Hoburg and tenth for Bowen, tying him for the most spacewalks by a U.S. astronaut along with Mike Lopez-Alegria, Bob Behnken, Peggy Whitson, and Chris Cassidy.

Hoburg and Bowen are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASAís Artemis program.
