quote:Originally posted by LM-12: Does Wikipedia show the STS-135 EVA as the 242nd US EVA?
That is listed as number 241 on Wikipedia. I will look and see if I can find the discrepancy.
Update:
Wikipedia, it turns out, is not missing any EVAs, they just have the label for 100th in the wrong place (one EVA later than it should be). It's based on a NASA status report that claimed the February 14, 2001, EVA as the 100th but it appears they issued that statement one EVA too late by mistake. I wonder why that happened at the time, though.

Good of you to catch that error.
So that still leaves the question of how NASA came up with the "300" number in their July 13 press release.
Maybe this is how: if you include the seven LM equipment jettisons on the lunar surface, then you get 300 US EVAs (293+7). Could that be it?

I asked NASA public affairs to clarify and if possible, provide a list of the 300 spacewalks. They didn't have a list to share, but confirmed the above:
...some of the technical definition of spacewalks involve the opening of a hatch during Apollo and tossing trash out.

That begs the question, why did they decide to count those now and not in the past? That would mean rewriting the books and changing when the 100th one was too.

I inquired to NASA and got the following list back:
169 EVAs out of ISS airlocks
82 EVAs out of Shuttle airlocks
3 outside the Mir Space Station
10 outside Skylab
21 at the moon (including stand up EVAs to discard trash)
4 outside Apollo command modules (for photography or film retrieval)
9 outside Gemini capsules
By my count, the number post-Skylab is 253 but NASA is saying 254 here.
(They show six for lunar trash).

By my count, the NASA list has one too many ISS spacewalks (it should be 168 before today) and one too few Apollo trash jettisons (it should be seven).
So the total is still correct, but the breakdown by program accounting is wrong.

To prepare for two of its astronauts marking a new milestone in space, NASA has decided to rewrite the records for many of its historic missions, including the first moon landing.
As history records, Apollo 11 crew members Neil Armstrong and Buzz Aldrin performed the first-ever moonwalk on July 20, 1969, 51 years ago Monday. The astronauts' 2-hour, 31-minute and 40-second outing to explore the lunar surface was recorded by newspapers, historians, authors and by NASA, itself, as the mission's only extravehicular activity, or EVA, the technical term for spacewalks.
But with a recent press release, NASA effectively added a second EVA to the first moonwalkers' credit — and the agency did not stop there.

Whenever EVA numbers come up always brings up the question/rumor of an EVA on STS-27. Did it happen or did it not?

This was not counted above as an EVA, but it is worth noting that the Skylab 2 crew was suited up in a vacuum in the command module to troubleshoot their docking problem. The side hatch was not opened, but the overhead hatch was opened and the docking probe was removed and inspected. Conrad called it their second EVA, and it was referred to as an EVA in a Skylab press conference.

In this NASA video from Sept. 8, 2020, there are all four EMU units around Chris Cassidy, but the left one has the Russian flag on its left arm. Is it any schedule of US with Russian spacewalk or 20th anniversary of the ISS only?

I believe the EMU is configured for Anatoli Ivanishin just in case an emergency EVA is needed while the space station is still limited to only three crew members.

Where will Kate Rubins be during that spacewalk?
Soyuz MS-17 will be docked to Rassvet, so I'm guessing that she will not have to stay there during the EVA. Is that correct?

If all goes well I think it will be exactly what you guess. Certainly, more details will be known closer to the space walk.

Currently onboard the ISS are five EMU units: 3004, 3006, 3008, 3009 and 3015 after CRS-21 Cargo Dragon delivering the last one. EMU unit 3008 will be return to the Earth on that craft in January 2021.

All four EMU spacesuits currently onboard the ISS can briefly be seen in this Expedition 71 video clip about sizing the suits:
The Expedition 71 crew members are getting ready for spacewalks in the coming weeks. This week they tailored their spacesuits to fit just right for when they go outside the International Space Station for maintenance and science work.

Here is a description of the next three ISS spacewalks from the June 7, 2024 news release:
For the first spacewalk, NASA astronauts Tracy C. Dyson and Matt Dominick will exit the station’s Quest airlock to complete the removal of a faulty electronics box, called a radio frequency group, from a communications antenna on the starboard truss of the space station. The pair also will collect samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory.
Dyson will serve as spacewalk crew member 1 and will wear a suit with red stripes. Dominick will serve as spacewalk crew member 2 and will wear an unmarked suit. U.S. spacewalk 90 will be the fourth for Dyson and the first for Dominick. NASA will announce participating crew members for U.S. spacewalks 91 and 92 following the completion of the first and will provide additional coverage details.
For the second spacewalk, astronauts will remove and replace the external high-definition camera located at camera port nine on the orbiting laboratory. This camera is one of several to provide external views of the space station. Additionally, crew members will complete a cable connection fit check for the alpha magnetic spectrometer, a particle physics experiment on the station’s exterior. If not completed during U.S. spacewalk 90, the astronauts will begin by collecting microorganism samples.
For the third spacewalk, crew members will remove and replace a rate gyro assembly, which provides data on the orientation of the space station. Astronauts will then attach a support bracket, called a modification kit, in preparation for future installation of the orbiting laboratory’s next International Space Station Roll-Out Solar Array on the 2A power channel on the port truss.

By my count, there were 109 shuttle EVAs at the ISS: 28 were from the shuttle airlock, and 81 were from the Quest airlock.
The first EVA from the Quest airlock was EVA-3 (Gernhardt, Reilly) on STS-104. The last EVA from the shuttle airlock was EVA-3 (Robinson, Noguchi) on STS-114.

The last time I can find that a shuttle airlock was used on any space shuttle flight was EVA-5 (Feustel, Grunsfeld) on the STS-125 Hubble repair mission. They used the aft hatch of the external airlock, seen in this photo:
