NASA considers 'fuel stops' in space

Nasa Fuel depot
NASA is looking to accelerate plans to send astronauts to distant destinations by considering a proposal to put filling stations in the sky.

The filling stations - NASA calls them propellant depots - would refuel a spacecraft in orbit before it headed out to the moon, an asteroid or eventually Mars. Currently, all of the fuel needed for a mission is carried up with the rocket. The weight of the fuel limits the size of the spacecraft.

Next month, engineers will meet at NASA headquarters in Washington to discuss how propellant depots could be used to reach farther into space and make possible more ambitious missions using the heavy-lift rocket that NASA is planning to build. The discussions grow out of a six-month NASA study of propellant depots, completed in July.
