The EVA today (USA EVA-51) on Expedition 56 now ties the number of Russian EVAs at the ISS. It also happens to be the 51st EVA at the ISS since the last shuttle flight. |

There were two joint EVAs on the Expedition 12 mission. McArthur and Tokarev wore EMU suits on the first EVA, and Orlan suits on the second EVA. |

- Vladimir Titov
- Yuri Malenchenko
- James Voss
- Carl Walz
- Daniel Bursch
- David Wolf

From what I have read, there could be about a dozen EVAs at the ISS between now and the end of the year.

Here are the EVA assignments as of today (Oct. 4). As it presently stands, pending the first three spacewalks, the fourth battery replacement EVA will be an all-women EVA.  |

It appears that the USA EVA schedule has also been changed. From today's NASA update:
Astronauts Christina Koch and Jessica Meir will venture outside the International Space Station late this week to replace a power controller that failed during the weekend. The spacewalk, the first ever that will be conducted by two women, is planned for Thursday or Friday. Station managers decided to postpone previously planned spacewalks that had been set to install new batteries this week and next in order to replace the faulty power unit, called a Battery Charge/Discharge Unit (BCDU). |

Soyuz MS-16 commander Nikolai Tikhonov might be the next cosmonaut to wear an EMU spacesuit on an EVA. Tikhonov is training to use a U.S. spacesuit — known as the Extravehicular Mobility Unit — for possible spacewalks outside the station. Four Russian cosmonauts have performed spacewalks with U.S. spacesuits, most recently in 2007, before the space station crew size was expanded from three to six. |

The cosmonauts wore a Russian flag on their EMU suits, but not all the NASA astronauts wore a US flag on their Orlan suits. John Phillips wore a Russian flag on his Orlan suit. There may have been others.Andrew Thomas had no flag on his EMU suit.

Christina Koch has made the last EVA on her 311th day in space mission.It's not the longest time with such period. Russian cosmonaut Sergey Avdeev has made EVA on 349th day of his flight aboard Mir station on July 28, 1999. |

Assuming there are two EMU spacesuits hanging in the Quest module, one might wonder where other EMU spacesuits onboard are kept.This Expedition 21 photo shows that back in 2009, there were three EMU spacesuits stored in the Columbus lab. |

This NASA article today about spacewalks at the ISS mentions some of the joint EVAs: One of the stated objectives of the Shuttle Mir Program, also known as Phase 1 of ISS, was for the United States and Russia to learn to work together as the two former adversaries prepared to jointly build and operate the space station. One arena where this was clearly demonstrated was in spacewalking. As Phase 1 progressed, astronauts living and working aboard Mir became more involved in the station's operations, including conducting EVAs. On April 29, 1997, Jerry M. Linenger became the first American astronaut to perform an EVA in a Russian Orlan spacesuit with his Mir 23 commander Vasili V. Tsibliev. C. Michael Foale and David A. Wolfe added to that experience base with their Mir Orlan EVAs later that year. Foale became the first person to perform EVAs in both the US EMU and the Russian Orlan spacesuits. On Oct. 1, 1997, Scott E. Parazynski and Vladimir G. Titov performed the first joint US-Russian EMU EVA during STS-86 while Space Shuttle Atlantis was docked to Mir. Titov was also the first non-American to conduct a Shuttle based EVA ...Astronaut Edward T. "Ed" Lu and cosmonaut Yuri I. Malenchenko conducted the first US Russian EVA at ISS during the June 2000 STS 101 mission. The two connected electrical and data cables between Zarya and the newly arrived Zvezda module. Training for that spacewalk required Russian engineers to modify the Hydrolab facility at the Gagarin Cosmonaut Training Center to accommodate the US EMUs. Similarly, American engineers adapted the Neutral Buoyancy Laboratory at Johnson Space Center to allow the Expedition 1 crew to train using both the EMU and the Russian Orlan spacesuit ... Following the Space Shuttle Columbia accident, ISS EVAs continued but only from the Russian segment with the added complication that with the resident crew size reduced to two, the pair of spacewalking crewmembers left no one inside the station to monitor its systems. Although this posed a slightly increased risk should something go wrong, these "two-person" EVAs proved essential during the Shuttle hiatus. Expedition 8 crewmembers Aleksandr Y. Kaleri and Mike Foale conducted the first such EVA on Feb. 26, 2004. Foale had prior experience with the Orlan suit as he had completed an EVA during his long-duration stay aboard Mir in 1997. The crew had to cut the EVA short due to Kaleri's suit overheating and water droplets forming inside his helmet. The crew later identified the problem as a kink in the water line in his liquid cooling garment. The incident provided a preview of a more serious problem to occur in an EMU during an EVA more than nine years later. |

According to a NASA press release, EVA-68 will be... ...the 300th spacewalk involving U.S. astronauts since Ed White stepped out of his Gemini 4 capsule on June 3, 1965. Is it correct? |

The Wikipedia list of spacewalks, which is very detailed, shows 290 U.S. EVAs to date and so would be 292.Just trying to figure out where the discrepancy might be, or if you are perhaps counting the unconfirmed STS-27 EVA? |

I did not count the unconfirmed STS-27 EVA. Not sure where the discrepancy is.Maybe we can narrow it down. The last US EVA listed in the "Walking to Olympus" chronology is the STS-135 EVA, which they have as US EVA 242. Does Wikipedia show the STS-135 EVA as the 242nd US EVA? |
