Asteroid 24 Themis as a Space Gas Station?

The discovery of water compounds on the asteroid 24Themis brought a possibility of having a space gas station for manned space flights. Water can easily be converted to hydrogen fuel through a simple electrolysis or can be purified to be used as drinking water for the astronauts.

Today's space mission carries a lot of supplies from the earth (i.e water) which makes the rocket payload much heavier. Having a water supply on or along the way to the destination will be a big reduction on the weight of the space craft and the power requirement of the rocket that will carry it.

The challenge though lies in the fact that the gravity on 24 Themis is far less than that of the Earth. It will be a real challenge on how extract water from the lonely asteroid.

Could Asteroids Be Earth's Water Origin?

The theory that asteroids crashing with the Earth nearly four billion years ago could have been the seed to Earth's water seems to get more consideration recently. The new attention came after a team of astronomers found organic compounds in an asteroid.

The asteroid named 24 Themis situated between the orbits of Mars and Jupiter was found to be coated with thin layer of frost.

Is this evidence will be the final touch on the old theory? What questions are still unanswered and what explanations we have so far?
