Today I was reading from Popular Science and found this article. A Canadian company is confirming the launch of a space station designed for fuel ups and minor repair. A giant arm will help initiate each fuel up as well as perform minor repairs. The example given is "pulling open a jammed solar array" but if it is jammed, wouldn't pulling it open forcefully break the joints?
The video explains it is much like a servicing truck, able to refuel, repair, and even tow if necessary. It takes quite a bit of time for it to get from place to place, but it should still be cheaper then having to launch people from Earth for each individual repair. This will also keep billions of dollars from being wasted when fueless/dead satellites burn up in Earth's atmosphere.
This is very exciting for me as I am a huge fan of space travel. This is a small, but essential step in the right direction for people to travel frequently from Earth to space to wherever past that.
