1.   Spacecraft use electricity, while they are in flight, to provide power for computers and other electrical equipment.

2.   Starting in a week, the spacecraft will use the upper fringes of the Martian atmosphere to lower and circularize its orbit through a technique called aerobraking.

3.   That spacecraft used solar power to run an engine that continually pushed it with very low thrust to high speeds.

4.   To observe this region, the spacecraft use special telescopes called coronagraphs, which let in only the extremely faint illumination from the corona region.

5.   An alien spacecraft uses advanced ion propulsion, impressing the crew of the faster-than-the-speed-of-light starship Enterprise.

6.   The spacecraft uses gyroscopes to control its position in space.
