So 8.8 billion dollars cost to build the telescope, if at some point the telescope requires maintenance Nasa won;t be able to fix it cause its too far in space. very smart

So the European Space agency is somewhat involved in this project? If that's the case, i think this telescope will just crash into Mars.
