Updates ISS UPDATES

I wonder how'd they'd go about generating artificial gravity.
Would they use some sort of massive rigid structure that would need to be assembled or would it be some sort of inflatable...

Bigelow Expandable Activity Module (BEAM)?

first module was to replace the American segment of the ISS in the field of energy
orbital data of the new station inclination 97° (instead of 51° for the ISS) altitude 900 kilometers (400 for the ISS)

Is that mean that only the international segment of the ISS will be decommissioned in the 30s and the Russian segment will live long after this?

Edit: No, it is a completely new station with a polar orbit.

I love the way that module looks!

Spacewalk later today to outfit the Nauka and Pirchal modules - https://blogs.nasa.gov/spacestation...for-spacewalk-and-dragon-departure-this-week/
I've only ever seen bits of spacewalk, will try to watch the full spacewalk today.

I've tried to watch one, they're kinda long and boring.

While going through the recent ISS exterior images, I saw an amazing high-quality picture of the complete ISS that unfortunately has a damaged radiator at the S1 truss. Has this damage happened last year? Or is it a permanent damage from the Shuttle days?

S1 Radiator in 2021 (during Crew-2):

S1 Radiator in 2009 (during STS-119):

The damage became known in 2008. We even have an add-on from Donamy for his ISS A2Z.

The International Space Station will be deorbited into Point Nemo on January 2031:

Seems sad, but it is the only way to get rid of ye olde space statione.

Why deorbit it? Why not sell it to a private company if NASA/Roscosmos don’t want to maintain it? IIRC, this was considered for mir…

ISS is very expensive to maintain, it really does require all the various engineers you see in the ISS Flight Control Room to operate as well as their backroom support. Also, ISS is very old and is degrading. ISS is now far older than Mir (ISS 23 years vs Mir's 15 years). By the time it's splashed in 2031, it will have doubled Mir's life-span and have been in orbit for over 32 years.

Also, Mir didn't find any backers with deep enough pockets. The one taker, MirCorp, went backrupt just a few years into operations. I'm sorry but this was coming, ISS is done, it was never intended as an permanent space station.

Yes and remember that all the plumbing used for cooling, also fuel tanks eventually corrodes, especially with ammonia loops and hypergolics. A space station is a technical object like a washing machine or a car. You can replace parts, but eventually it has a lifetime, there's little to do, and it is far too heavy to be moved to a safe parking orbit. I'd say it served well and had a good life.

A "Valerian and the City of a Thousand Planets" future for the ISS is impossible from the get go

While the ISS has no plans to be sold to a private company, some of its components (especially the Leonardo PMM) will be used to form a private space station operated by Axiom Space, as shown in an animation.

All very good points… just seems sad to let go of it. I guess the next question is how to deorbit it, a single Progress certainly dosen’t have the dV.

IMHO two Progress spacecraft docked at Prichal and Rassvet combined have twice the ∆v than a single Progress spacecraft docked at Zvezda.

 

[N_Molson]

The russian modules have engines and hypergolics tanks that can be refueled by Progress.
