The Future: James Webb and Beyond
With the advent of the 21st century and the realization of humankind’s limitations for travel, we are ever more reliant upon remote sensing to determine some of the most fundamental questions we can imagine. These are questions that are unlikely to be answered by manned space flight between planets, but they may be answered by highly advanced equipment like Hubble. Even so, it will be necessary to maintain a manned space programme, as space telescopes will require human intervention from time to time for servicing. As we are unlikely to ever be able to travel to these far-distant stars for ourselves, it is the light which we can garner through our instruments from these distant objects that will tell us about the universe.
