SpaceX Scores $843 Million NASA Contract To De-Orbit ISS In 2030 (techcrunch.com) 142

In a contract worth as much as $843 million, NASA announced today SpaceX has been selected to develop a vehicle that will de-orbit the International Space Station in 2030. "As the agency transitions to commercially owned space destinations closer to home, it is crucial to prepare for the safe and responsible deorbit of the International Space Station in a controlled manner after the end of its operational life in 2030," the U.S. space agency said in a statement. TechCrunch reports: Few details about the U.S. Deorbit Vehicle, as NASA calls the craft, have been released so far. However, NASA clarified that the vehicle will be different from SpaceX's Dragon capsule, which delivers cargo and crew to the station, and other vehicles that perform services for the agency. Unlike these vehicles, which are built and operated by SpaceX, NASA will take ownership of the U.S. Deorbit Vehicle post-development and operate it throughout its mission. Both the vehicle and the ISS will destructively break up as they reenter the atmosphere, and one of the big tasks ahead for SpaceX is to ensure that the station reenters in a way that endangers no populated areas. The launch contract for the U.S. Deorbit Vehicle will be announced separately.

NASA and its partners had been evaluating using a Russian Roscosmos Progress spacecraft to conduct the de-orbit mission, but studies indicated that a new spacecraft was needed for the de-orbit maneuver. The station's safe demise is a responsibility shared by the five space agencies that operate on the ISS -- NASA, the Canadian Space Agency, European Space Agency, Japan Aerospace Exploration Agency, and State Space Corporation Roscosmos -- but it is unclear whether this contract amount is being paid out by all countries.

      I've never understood why it wouldn't be cheaper and safer to put it in a parking orbit somewhere outside geostationary orbit. Leave it there as a museum, or possibly spare parts for some future endeavor. IIRC that was the original plan for MIR, but the Kremlin was afraid some phantasmagorical classified information might be pillaged by a visiting US Space Shuttle visit so they crashed it.

        My summary of the ISS options NASA analyzed:

        Uncontrolled reentry: Bad.

        Disassembly + return: Impractical/expensive.

        Disassembly + LEO repurpose: Not worth it.

        Disassembly + deorbit: Can't break up and still operate.

        Boost: No vehicle and very risky (short and long term).

        Give to commercial: No proposals.

        Continue operations: Possible.

        ISS orbit altitude (maximum) - 460 km
        Geostationary orbit altitude - 35,786 km

        ISS velocity - 28,165 km/h
        Geotationary orbit velocity - 11,052 km/h

        It's much cheaper, easier, and requires vastly less fuel to slow the ISS down the few hundred km/h needed so it gradually de-orbits and hits the atmosphere than it is to move it 35,000+ km higher and slow it down by 17,000 km/h.

        • by cusco ( 717999 )

          Yeah, after I posted that I rethought the "cheaper" part. I don't know about "easier" though, it's pretty difficult to believe that the thing isn't going to break into pieces with solar panels and various modules coming down wherever they damn well please. Maybe the core can be dropped on Antarctica or the Southern Ocean, but the joints holding the other segments together were never designed to handle that kind of stress and unless they cut it into chunks and zip tie the whole thing into one big blob it's

          • I know everyone has not played orbiter or kerbal space program...but learn some orbital physics before posting on the nerd site. The IIS inclination is approximately 50 degrees. To change inclination it takes at least 50% mass fraction of the entire payload to make that higher inside the moons orbit. Dropping it on moscow at 55 N to return their hardware might be worth the FU effort of about 3 starship fuel tankers of delta V. Bet by 2030 the management team in moscow will be quite different.

          Is it though? They're talking about a contract worth nearly $1 billion dollars to develop a new vehicle, which does not appear to include the cost of actually performing the de-orbit (since NASA will be operating it, not SpaceX). I'm not familiar with the topic, but surely it would be possible to use existing vehicles and relatively inexpensive thrusters to boost the ISS into some kind of parking orbit which, even if not permanently stable, would keep it aloft for another 15-20 years until we figure out a

        • And if it was left as is? How long would it take for it to deorbit itself? (probably in less controlled process?).
          Or just keep it orbiting with minimum effort?

          I am curious though I am sure all these were already evaluated.

        • You dont slow it down to go higher... You push it faster so it is pushed farther from the other body. Then you use a smaller fraction to circularize the orbit so the next transfer can be done cheaply at nearly any time. Hohmann transfer orbit. Push Prograde - Higher.
    • I wonder whether SpaceX will also bring the Boeing Starliner capsule down, or will they leave it up there flying a while longer on its own?
    • US: Here's a billion bucks, please deorbit safely.
      China: Safe deorbiting? What's that?

  • It would be a damn shame if we didn't have something else up there by then. Humanity has been continuously in space since the year 2000 (IIRC), it would suck to end that and have to restart that clock.

      Why would that matter? It's pure symbolism. How about we take the time to design the next thing even better so it has more value and put it up when ready?

      • by MacMann ( 7518492 ) on Thursday June 27, 2024 @06:30AM (#64581977)

        Why would that matter? It's pure symbolism.

        Symbols have meaning. That's why we use them.

        Consider the symbolism of the Terra Nova Expedition reaching the South Pole only to find a flagpole with the Norwegian flag indicating that the Amunsen Expedition got there first. Reaching the South Pole is symbolic in that it indicates a capability not seen before. Planting a flag symbolizes that accomplishment. If there's a time in which there's no humans in orbit then that symbolizes a falling back in human capability. If this isn't quickly rectified then it can symbolize even greater decay in human civilization.

        We plant literal markers in human accomplishment to show to others, and ourselves, what we can do. If those markers are lost then that indicates a failure somewhere in our desire to progress in technology, capability, knowledge, or some other area.

        I doubt there is such a thing as "pure symbolism" since to be a symbol it must have some meaning beyond its existence.

        • Given a choice between "let's throw something up there fast so we don't have to reset the clock!" vs "It'll take an extra 5 years but we have to live with this thing for at least 20-30 years so let's do it right", which sounds like the adult decision to you?

          Do you think the average citizen has any clue how long it's been up or will really care if there's a short gap while the next better thing gets finished?

          Symbolism is about morale boosting rah rah. No one important cares.

        • We have dozens of symbols out in space already though... plenty of dead and working satellites, probes still in orbits some places, the Voyagers out past the heliopause and hell the JWST is probably one of the modern Wonders of the World.

          The ISS unfortunately is dying and sometimes you just need to let go. Like an old dog are you keeping it alive for it's sake or yours?

          We shouldn't be mad about the ISS getting burned up, we should be mad if we haven't made progress on better things when 2030 rolls around.

        Why would that matter? It's pure symbolism.

        No it would be a failure. It would indicate a backsliding on our commitment to space, much like after the Apollo program was ended.

        • We're where we're at. You'd prefer to toss some crap up there just so we don't have to "reset the [imaginary] clock" than do it right?

          I don't want limited dollar wasted on useless junk for symbolism's sake. There will be another. When it's ready.

          Holy fuck, we haven't had a new GTA6 since fucking forever! Everyone is still playing GTA5! The entire GTA series is a failure! What happened to our commitment to video game based crime?

            No, I'd prefer that were we genuinely committed to furthering our presence in space for scientific, commercial and environmental reasons.

        There are plenty of "even better" designs, and have been since before the ISS was even launched. What is lacking is the funding. This is why we can't have nice things:

        2024 NASA budget - $24.9 billion
        2024 Pentagon budget - $825 billion
        Space Farce portion of Pentagon budget - $29 billion

    • We need a base on the moon. The next space station is supposed to be "Lunar Gateway" which is going to be in lunar orbit .. I think we need to actually be on a base on the moon and skip the half-ass lunar gateway step.

      If you count China as part of humanity, then "we" probably will still have at least something up in space by 2030. China has built their own space station in orbit and last I heard they are still planning to expand it. No way will it be retired in any time soon.
      • by drnb ( 2434720 )

        If you count China as part of humanity ...

        Of course. The Soviet Union was a pretty f'd up thing, but their space program was one of the few great things they did. Why would China's peaceful accomplishments in space be any different?

      NASA is ceding low Earth orbit to private companies. If you want to put up the next station, go ahead and fund it.
    • by necro81 ( 917438 )

      Humanity has been continuously in space since the year 2000 (IIRC), it would suck to end that and have to restart that clock.

      China's Tiangong station [wikipedia.org] also exists, and has a continuous crew rotation [wikipedia.org]. It's fair to think that China will maintain a manned space station for the foreseeable future, so even if ISS disappeared tomorrow, the "clock" would keep running.

    • Lauren Sanchez' BF or hubbie (never know with celebrity tabloids) can't even launch into orbital space realms (LEO, MEO, GEO), so what has he got to sue for when his "pet toy" of a company can't even perform like SpaceX?

      Srsly the folks at BO need some form of "rocket v1agra" for their inventions to get them to perform any better than their past suggests.

      Doesn't anyone else think that BO is nothing more than very expensive "Billionaire Envy" (of Leon Musk' SpaceX) on the part of Bezos?

    NASA will take ownership of the U.S. Deorbit Vehicle post-development and operate it throughout its mission

    This is certainly for insurance purposes. No non-government entity would assume the liability of being sued out of existence if their actions resulted in injuries, death or property damage due to deorbiting the ISS. The government is much harder to sue than anything else. It's a certainly that large portions will reach the surface of the earth. It's mainly a matter of where.

    • I believe one of Randal Monroe's books - How To or one of the What If books, contains an interview with Chris Hadfield on how to survive on the ISS as it de-orbits. Not that the odds are good, but it's theoretically possible if you choose the right section to shield you during the majority of the trip.

      Presumably at some point you have to abandon your 'safe' tumbling debris, and then reduce your terminal velocity with a parachute you've fashioned out of some available materials on the ISS. You WERE stitch

  • "...transitions to commercially owned space destinations closer to home, "
    What does that even mean? You could hardly get closer to home than the ISS which inhabits such a shitty low orbit it's practically skipping on atmosphere.

  • Don't worry, I'm sure the US Space Force will be launching bases into orbit fairly soon. Other countries have similar plans.
  • How cool would it be to say you're the guy who sent the flaming wreckage of a space station into the earth?

    I mean like ok I don't make any promises where it will hit or what section of what high density city might get wiped out but you get what you pay for.

  • Let's be honest here, Elon is looking at a modified Starship to do a controlled burn. Probably a dock on the nose and push the station's perigee down until the station comes down at Point Nemo? That would be cheapest and make the most sense with existing technology.

  • There are technical papers aplenty about what it takes to de-orbit the ISS. You can do it gradually, but that tends to result in a larger debris field and less control over location. Better is to impart a larger delta-v all at once, so that the station comes down steeply into the atmosphere at a better-constrained location.

    Scott Manley on Youtube has a great video [youtube.com] explaining this in lay terms. You need to supply a delta-v of about 100 m/s. A single Progress supply mission can do about 4.5 m/s. You c
