Aug 26, 2017 at 21:38 comment added Anthony X Could the hydrogen be stored in a hydrocarbon, say methane, and chemically decomposed to feed to the engine? As for the carbon, could it not also be used as a propellant in the same way?

awesome answer; changed random units to SI units.

May 6, 2016 at 0:53 comment added Mark @Linuxios, the solution has been to use up the hydrogen before heat becomes an issue. Keeping hydrogen liquid for an hour is much easier than keeping it liquid for years.
Nov 21, 2014 at 19:48 comment added Linuxios The hydrogen boiling point problem is hard, but not unsolved. Hydrogen has been in use as a fuel for a long time, usually burning with liquid oxygen. The Space Shuttles used it too.

Jul 25, 2013 at 10:13 comment added robguinness Yes, solar-powered plasma thrusters have been used for many years, especially in HEO communication satellites. Another form is solar sail technology, which uses the momentum of photons directly to propel a spacecraft. This is much more experimental, but some demonstrator missions have been flown as proofs of concept.
Jul 25, 2013 at 9:04 comment added user106 @robguinness you could argue we are technically already doing it, Juno is going to jupiter only through solar power i hear
Jul 25, 2013 at 8:59 comment added user106 @robguinness good point, i hadn't considered that, i will find some more information and edit it in
Jul 25, 2013 at 8:57 comment added robguinness No mention of solar-based propulsion systems? Of course, they start to become less effective as the probe moves away from the Sun, but they in turn gain more efficacy as they approach other stars...
