Taking out the Space Trash

Currently when ISS has trash it sends it back in a Dragon module which has 10 m^3 of human rated volume.  With the addition of some ports to allow long term parking of dragon modules and a space hatch that can be pressurized and depressurized it would be possible to have a “trash bag” module that isn’t even pressurized but is able to store trash and act as a vehicle for reentry and burn up powered by a single dragon module.  You could almost imagine it being an actual trash bag that is multiple times thicker.  It only has to last

Building a space station cheaply should involve re-using all the pieces that are already made and thrown away or COTS parts that have been tested in space. But if you tried to do that today there would be a lot of engineering to integrate those technologies.  So there is room for the “operating system” company to take all the individual space “apps” and combine them into something resembling space station 2.0 and like Microsoft they may eventually emerge owning everything. Space X has 190 m^3 of fully tested human rated volume they are sending to space in the form of

In 2100 several industries are advanced enough on Mars that they can function independently from Earth. Mars has a way to manufacture their own solar or solar thermal power without consuming any Earth resources, using Earth manpower, using Earth computers or machines etc. Mars has its own Mass Driver like a coil-gun or railgun that can launch mass from Mars surface to outer space to orbit around the sun.
