Refuelling stations could be placed in orbit to allow departing spacecraft to fill up before heading out.
One of the biggest obstacles in launching spacecraft is the weight of fuel needed which limits the size of the vehicle. If a spacecraft could launch and then refuel in orbit before heading towards its destination then this could open the door to manned exploration of Mars and beyond.
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, and the weight of the fuel limits the size of the spacecraft.
