#NASA indefinitely delays ⏳ return of Starliner. During a pair of news conferences since #Starliner docked to the station officials have downplayed 🙈🙉🙊 the overall seriousness 😱 of the issues. But they have yet to fully explain why they are not yet comfortable with releasing Starliner to fly back to Earth under normal circumstances. https://arstechnica.com/space/2024/06/nasa-indefinitely-delays-return-of-starliner-to-review-propulsion-data/

Since all launch vehicles are specialized - and literally #RocketScience - the #FAA believes operators are best suited to sniff out root causes and identify corrective actions. The agency estimates that in-house investigations could take the agency 10-20 times longer 🥱.
As for #HumanSpaceflight / tourism, the industry has been operating under an eight-year “learning period,” where the FAA is restricted from enacting regulations. The learning period is set to expire on 📆 Jan. 1 https://payloadspace.com/the-gao-calls-for-the-faa-to-improve-its-mishap-investigation-process/

Reaching #orbit means accelerating up to around 28,000kph (22 times the speed of sound). A five-gram #bolt 🔩 hitting at #OrbitalSpeed packs as much #energy 💥 as a 200kg weight dropped from the top of an 18-storey building. The typical #radiation ☢️ dose from one day in #space is equivalent to what you’d receive over an entire year back on #Earth https://www.sciencefocus.com/space/space-travel-exploration

#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

🚀 #SpaceX launches and landings, once bordering on #magic, have become #predictable, if not monotonous. “This is not #routine,” said Benjamin Reed, the senior director of #human #spaceflight programs at SpaceX. “When you are sending #people into space, you cannot err,” said William Gerstenmaier, the vice president of build and flight #reliability at SpaceX https://www.nytimes.com/2022/12/29/science/spacex-launch-mission-control.html

#NASA “We're not calling this a #rescue #Soyuz. No immediate need for the crew to come home. I'm calling it a replacement Soyuz.” 🙈 🙉 🙊 Launch 📆 postponed until early March https://aviationweek.com/defense-space/space/roscosmos-delays-soyuz-ms-23-launch-until-early-march

The #WaPo also uses the bad "R"-Word 😁 "Since Roscosmos is now sending that spacecraft as a #RescueVehicle 🧷, the replacement crew won’t fly until September." https://www.washingtonpost.com/technology/2023/02/15/space-station-rescue-delayed/

#Micrometeroid ☄️protection : #Starship is made of 4mm stainless steel. The #ISS got so-called "Whipple shields".

'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 ?'”
