Ars asked two #NASA spokespersons for details on the proposed leak repair and why the agency decided that the repair was risky enough to order the US crew members into the Crew Dragon lifeboat. They did not provide answers to these questions as of the time of this publication

How long could a #humanoid #robot 🤖 operate on #Mars 🔴 ?

Rover examples :
#Spirit: 7 years
#Opportunity: 15 years
#Curiosity > 10 years

Often-times a “bare” #robot cannot operate in the intended environment. Extremes of #temperature ❄️🌡️ is just one example. #Robosuits can be augmented to supply either cooling or heating to keep the #robot within OEM temperature specifications https://www.roboticstomorrow.com/article/2018/06/protecting-your-robot-with-robosuit/12076

The first time a commercial #robotic spacecraft captures a government #satellite 🛰️ that is uncrewed and was not originally designed to be serviced 🔧 in space.
#Swift has gradually been losing altitude ⤵️ due to atmospheric drag. On top of that, recent increases in the Sun’s ☀️ activity has caused Earth’s #atmosphere to swell, intensifying drag and speeding up the process https://www.astronomy.com/science/swift-observatory-rescue-mission

🇨🇳 #Shijian25 is expected to use its robotic arms to latch onto #Shijian21 and replenish its fuel ⛽. The latter used up much of its propellant in 2022 while towing a defunct #BeiDou navigation satellite 🛰️ into a higher graveyard orbit. @planet4589 said the behaviour of the #American 🇺🇸 satellites was highly uncommon. https://www.scmp.com/news/china/science/article/3314364/chinas-landmark-orbital-refuelling-mission-why-2-us-spy-satellites-hover-nearby

@arstechnica The #SpaceAgency would welcome the return of #Spitzer not only for scientific purposes, but also to help characterize the #NEO #AsteroidThreat ☄️.

#SpaceMaintenance

#NASA 📆 April 2020 #Micrometeoroids and #SpaceDebris will strike an #orbiting Station throughout its lifetime, as is evident on the #ISS, where several #solar arrays show #damage caused by micrometeoroids. The #hope is that the #meteoroids will not hit any #critical areas and cause #emergency #evacuation of the structure. Damage from meteoroids may include damage to #habitation 💤 modules.
#Welding is one of the best ways to create hermetic seals. The ability to #weld these structures without waiting for new equipment may limit the #risks to #astronauts in the event of damage.This ability for rapid #repair may also become more significant as orbiting Stations such as #Gateway move further from #Earth and the associated #cost of shipping parts increases. It is important to #develop these technologies now.

#NASA has recently funded work on #development of #spacewelding 🎇 capabilities https://ntrs.nasa.gov/api/citations/20200002259/downloads/20200002259.pdf

'You know, there is nothing we can do about #damage to the TPS. If it has been damaged it’s probably better not to know. I think the crew would rather not know. Don’t you think it would be better for them to have a happy successful flight and die unexpectedly during entry than to stay on #orbit, knowing that there was nothing to be done, until the air ran out ?'”

It is not the first leak on the #Soyuz. In 2018 the module sprang an #air #leak. #Astronauts used #tape to seal the leak after it caused a small loss of #pressure that was not #life #threatening https://www.theguardian.com/science/2022/dec/23/latest-soyuz-capsule-leak-prompts-russians-to-plan-possible-rescue-of-space-station-crew
