If a US spacewalk on ISS is necessary to repair its cooling system, the spare parts are there, but the spacesuits are not.
If a US spacewalk on ISS is necessary to repair its cooling system, the spare parts are there, but the spacesuits are not.
Prior to retiring the shuttle NASA, aware that cargo supply would be limited once the shuttle was gone, shipped up to the station as many spare parts as possible. Thus, there are three spare pump modules on ISS that could be installed during a spacewalk to replace the module that has the valve problem.
However, because of the water leak problem that occurred in one American spacesuit during a July spacewalk, NASA has halted all American spacewalks until replacement suits can be shipped up to the station.
Since then, NASA has been conducting extensive investigations into the water leak issue, with… “the crew performed a series of tests on EMU 3011 [the faulty spacesuit] as part of an ongoing effort for returning the suit back to service. The tests included water leak checks, communication checks, and suit pressure leak checks. EMU 3011 passed all tests.”
However, NASA had been planning to wait to return another EMU, serial number 3015, to Earth aboard a SpaceX Dragon vehicle and deliver a new EMU in its place before clearing EVAs to resume. However the next Dragon vehicle is not scheduled to arrive at the ISS until at least late February next year.
The Russians might be able to do this spacewalk, but they are going to demand payment for the work. And they won’t come cheap, considering the circumstances.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
