Sequence of maneuvers made by the Fermi Gamma-ray Space Telescope to avoid a potential collision with Cosmos 1805. The spacecraft rolled from its normal orientation to point along its direction of motion. It rotated its solar panels to keep them out of the way and stowed its antenna for the same reason. Then it fired its main thrusters for 1 second which altered its orbit slightly.
