Can the equipment used from several places on earth for this be deployed in space (may be to a geostationary orbit)? Not thinking about cost for a moment is this a far-fetched thought or such a thing is technically possible.
- Rebelgecko 8y agoYeah. There were a few NASA projects attempting to do this that got cancelled circa 2010 (programs called TPF-I and SIM). Something that has been done for a while is using a single telescope in space in conjunction with some on Earth. Russia has a radio telescope in orbit called Spektr-R. I think it died recently, but Spektr-R did interferometry with other telescopes on Earth. When it was operational, I believe it was the widest VLBI array— its orbit was higher than GEO (and even intersected the moon's!), so it got pretty good distance from the ground.
