** The Official Space Flight Thread - The Space Station and Beyond **

agreed. Re-frowned upon, only life you like them :D
i hadnt realaised spacex had been awarded the contract.
either let it fall to the ground, crash it in to the sun or another plannet.
tbh in to the sun it an option and safer.
i'd like to have seen it be used for onelast scientif purpose, like crashing in to an opbject or sent out to deep space as a long term reseach object or platform. RTG it up with science instruments sent it straight up/verticle instead of horizontal so we can create 3 point tri-angulations. it wont need a breathable atmosphere.

Sending things to the sun is unbelievably difficult - Superman 4 was utter garbage due to physics being a thing…

Found it Can't remember which site had the link to the NASA ISS deorbit decision, such parking orbit, reuse, and recovery. Clear summary for normal people if I find it again I'll link it I linked it.

One imagines that a modified Dragon Capsule(s) will be used to bring it down as one or in sections.

Even to deorbit it’s still 9 tons of fuel - a lot more than I expected. In classic Kerbal fashion, I’d guess the vehicle will just be an engine, a fuel tank and a docking port…

in relation to de-orbiting stuf... sooooo sun is better option :D

i had a quick skim through. they didnt discuss all options but i understand what they are getting at. de-orbit is best option for them.
also it was mentioned in : https://techcrunch.com/2024/06/26/spacex-scores-843m-nasa-contract-to-deorbit-iss-in-2030/

"SpaceX to develop a spacecraft that will de-orbit the International Space Station in 2030" so not something existing.

Must be a nice place to work that, easy commute, within walking distance of the city centre :eek:

I must say its quite funny - you see U.S rocket launches and for the most part they are in the middle of nowhere or far enough away from small settlements. Then you see China launch rockets right next to cities

I'd like to assume the Chinese do so because they simply don't care about health and safety - a common saying in China is that "human life is cheap and plentiful in China". And maybe that is part of it, but it certainly does make logistics easier too and so perhaps logistics plays a part in the location of their launch facilities

The worst one I could find on a quick google search is in jiuquan, the launch facility is about 2km from the nearest city lmao

You also always want to launch eastwards so you get a 1000km/h head start on your orbital speed, and over the water for obvious reasons. This creates issues for some Middle Eastern countries who have nothing but Iran in that general direction, and they generally don’t appreciate spent boosters and out of control rockets dropping on them…

Yep, Israel launch East to West for that very reason if memory serves.

i think they've shown the people incharge dont appear to care to much for individuals/citizenry. only end results. people are "replaceable". they have their 100year plan.

in this isntance with the rocket, it would not surprise me to find out some one(s) "disappeared". i would imagine its a loss of face in front of the "world". not something they would take well to.
downplayed to a mechanical fault..

Volunteers who lived in NASA’s Mars simulation for over a year will finally emerge today

The crew — Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones — is scheduled to exit the 3D-printed habitat in Houston this evening. You can watch the livestream of their return on NASA TV (below) starting at 5PM ET.

There are plans already for two more one-year missions,
No exact dates for the second CHAPEA mission have been set yet, but it’s expected to begin in spring 2025.

in case people missed it.
 
Latest Starlink flight has had a Stage 2 failure. What looks to be a LOX leak? Payload released at orbital speeds however in a lower than planned orbit. SpaceX have been working to use the Ion thrusters fully pegged to potentially raise them to a nominal LEO

During tonight’s Falcon 9 launch of Starlink, the second stage engine did not complete its second burn. As a result, the Starlink satellites were deployed into a lower than intended orbit.SpaceX has made contact with 5 of the satellites so far and is attempting to have them raise orbit using their ion thrusters.

We’re updating satellite software to run the ion thrusters at their equivalent of warp 9. Unlike a Star Trek episode, this will probably not work, but it’s worth a shot.The satellite thrusters need to raise orbit faster than atmospheric drag pulls them down or they burn up.

Thats been a phenomenal run of reliability! Statistically it was going to end at some point, and I fully expected it to be a reused booster failure rather than a brand new stage 2.

If it’s worked before it’ll work now, vs this is a new one that’s not been tested before?

Not sure what sort of refurb/teardown they do when they’re recovered..

I was thinking more along the lines of repeated refurbs will allow for wear and tear/fatigue or human interaction replacing older/worn out parts, more room for introduction of faults/flaws/human error. I would imagine there are checks for checks but when you have more potential for human interaction, I expect this to always be the weak point.
