In a first, Isro will make dead rocket stage 'alive' in space for experiments (alt)

Can a dead rocket in space be anything but debris? Isro believes it might actually be useful. Feted for its frugality and tech savvy, the Indian Space Research Organisation (Isro) is working on a new technology where it will use the last stage of the PSLV rocket for space experiments. It will perform a technology demonstration of this new system when it launches the PSLV C44 rocket in January.

Talking to [Times of India] here, Isro chairman K Sivan said, "Normally, the last stage of a PSLV rocket after releasing the primary satellite in space becomes dead and categorised as debris. It remains in the same orbit as that of the released satellite. Now, we are working on a new technology where we will give life to this "dead" last stage of PSLV, also called PS4 stage, for six months after its launch. This rocket stage will double up as a satellite. This will be the most cost-effective way to perform experiments in space as we don't have to launch a separate rocket for the purpose." He said that "India is the only country in the world that is working on this new technology".

Polar Satellite Launch Vehicle (PSLV).

NASA-Funded Blue Origin Study Could Lead to Repurposing of New Glenn Upper Stages in Orbit 12 comments

Blue Origin studying repurposing of New Glenn upper stages

Blue Origin has studied repurposing upper stages of its future New Glenn launch vehicle to serve as habitats or for other applications as part of a series of NASA-funded commercialization studies.

Brett Alexander, vice president of government sales and strategy at Blue Origin, said the company looked at ways it could make use of the second stage of New Glenn rather than simply deorbiting the stage at the end of each launch, but emphasized the company currently had no firm plans to reuse those stages at this time.

[...] That included, he said, turning those stages into habitation modules or other facilities for commercial use in Earth orbit. Those stages could be launched already outfitted for those uses or refitted once in orbit.

"We don't have actual plans at this moment" to reuse the upper stages in those ways, he noted. "We'll see what the best approach is at the end of the day."

Better to go fully reusable. New Armstrong?

    Ever watched a broadcast from the space station? There's so very little room, it seems. Just come up with a method to attach those things to the station, and people can "stand up", stretch, and exercise a little. Hook them together in a circle around the station, put a little spin to the whole mess, and they can "walk". Probably can't give them much "gravity", but anything at all would allow them to exercise muscle and bone that is working hard toward atrophy. .1 G would be better than zero G, wouldn't it?

      The efforts of India are to think economically, and we should give their idea a chance. For example, being a crude anti-satellite weapon. It may not have the fine manuerevering facilities of a proper satellite, but when the big war comes of all against all, their space debris could eject human shit in all directions, rendering the optical and most RF/microwave sensors of competing nations useless through attenuation of their signals.

      Human shit was used to great effect in human history, most notably with Punji Sticks coated with human feces during the Vietnam War. It is no coincidence that India also successfully launched a sattelite called SCATSAT-1 [wikipedia.org]

              Ethanol-fueled, was not like this. Quite the opposite! He was young, with a passion for positivity, filled with hopes and dreams to see the world. But one sad day, in his inebriated state, poor Ethanol-fueled lost his way and found himself in a gutter. Instead of ISRO, where he always wanted to go, shit stick to his face, and his penis. Shit was in his mouth, his nose and his bottle of fermented crap. It was everywhere. And why? Because ISRO, that's WHY!

              That day Ethanol went through a change.

              It is a cautionary tale.

      The correct solution to get more living space is known. Put up a Bigelow inflatable module.

      The largest design would have over double the volume of the entire ISS: https://en.wikipedia.org/wiki/BA_2100 [wikipedia.org]

      The more modest design, which should be built around 2020, will be about 1/3 of the volume of the ISS: https://en.wikipedia.org/wiki/B330 [wikipedia.org]

      SpaceX's BFR upper stage (Starship) would have a bit more volume than the ISS [wikipedia.org]. If the crewed versions are built for travel to Mars, then it should be safe to live in one while in the relative safety of low Earth orbit.

      The Nautilus-X [wikipedia.org] concepts not only spin to create false gravity, but could also be combined with Bigelow inflatable modules. An $83-143 million demonstrator could have been sent to the ISS, but it hasn't happened. With the U.S. committed to ISS only until 2025, and other partners only until 2028, any such plans are not happening, unless everyone agrees to keep the ISS from crashing and burning. If we build the stupid LOP-G in lunar orbit, maybe some of these ideas could be used there.

      Unless the dead last stage actually was on a mission to the ISS in the first place (not a random LEO satellite dropoff), it's not likely to be an option due to deltaV required.

      Fun fact. Back when the Space Shuttle was being developed there was a serious suggestion that the external tank (huge one between the side boosters) could be carried into orbit instead of being released and burning up. With a few small design changes, like adding an external hatchway, making two of the internal bulkheads removable, and some extra mounting points on the outside, the tank could be re-purposed into modules for a space station. The amount of extra fuel needed to carry the tank into orbit was well with in the capacity of the maneuvering engines, unless the shuttle was at max capacity, which almost never happened.

      Sadly the idea was not implemented. Given the number of times the Shuttle went up effectively empty the ISS would have been several time bigger than it is and a lot roomier.
