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".

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.

Wasn't the first time it was considered, either. There was the whole wet/dry workshop stuff with the Saturn upper stages.
