Constructing a Satellite in Space
Currently a satellite is expensive to construct on Earth and send out to space. Most often the components required to construct a satellite are launched to outer space and assembled in orbit around the Earth. This is a monolithic construction which can not be updated and changed to meet new requirements.
The outdated satellites are decommissioned and left to float around the Earth. Contributing to the rubbish in space. What if the satellites could be constructed organically in space? Scientists are considering the possibility of growing a platform on which interlinking pieces could be fitted to meet new requirements.
The satellite platform would be able to change as upgrades needed to be made. It would be possible to create antenna farms or solar power stations on such platforms that could be reassembled rather like a large jigsaw puzzle. Imagine the freedom to create structures in space this would give scientists.
While this idea is still just a thought, it is one which could make a lot of logistic problems easier to solve should it actually materialize. Eventually there will come a science project which will make it a reality. Then it will be much easier to imagine human beings living in space for much longer duration of time.
