| This guidance system reads gyroscopes and accelerometers and sends appropriate commands to attitude control thrusters. |
| These thrusters allowed the spacecraft to modify their orbits with less propellant than is the case with chemical engines. |
| Using small thrusters, the spacecraft will rotate so that the solar panels are oriented perpendicular to the Sun. |
| Proper lateral guidance, or guidance around the cylinder, is ensured by small rockets called thrusters. |
| Some of the mines move using rocket thrusters, others use a hopping mechanism and hold enough fuel to make 100 leaps. |
| The craft was streamlined, probably capable of atmospheric flight, with twin thrusters to either side of the aft section of the fuselage. |
