  • Dock a Refuel Module with the Space Telescope
  • Refuel the Telescope
  • Undock the Refuel Module
  • Point the Telescope outward into space
  • Budget: $20,000,000
  • Max time: 15:00


The Space Telescope is running dangerously low on thruster propellant. If not replenished soon, our science team will lose the ability to point the instrument.

Launch a Refuel Module into orbit. Once in orbit, dock the Refuel Module with the Telescope.

Tip. It is easier to dock with the Telescope when it is horizontal — it should have just enough fuel remaining to allow you to rotate it through 90 degrees.

Once docked, select the Telescope, switch to the fuel view, open the fuel valve between the two and set the Telescope's thruster propellant pump running.

Once the Telescope has finished refueling, close the fuel valve and jettison the module Point the telescope back out into space to complete the mission.


  • The mission briefing states that its easier to dock it when sideways; it should have enough fuel left to turn it sideways.
