Many spacecraft use small rockets called thrusters to move around in space. Thrusters can change the speed and direction of a spacecraft. They allow a spacecraft to steer in space, to jump to a higher orbit, or to fall back to Earth.  4, record 6, English, - thruster

The propulsion subsystem featured sets of small thrusters and a main engine. The thrusters were used to perform Odyssey's attitude control and trajectory correction manoeuvres, while the main engine was used to place the spacecraft in orbit around Mars. The main engine, which used hydrazine propellant with nitrogen tetroxide as an oxidiser, produced a minimum thrust of 65. 3 kilograms of force. Each of the four thrusters used for attitude control produce a thrust of 0. 1 kilogram of force. Four 2. 3-kilogram-force thrusters were used for turning the spacecraft. In addition to miscellaneous tubing, pyro valves and filters, the propulsion subsystem also included a single gaseous helium tank used to pressurise the fuel and oxidiser tanks. The propulsion subsystem weighed 49. 7 kilograms.  4, record 6, English, - thruster

Boil-off. When liquid propellants are stored at temperatures above their boiling-point they vaporize. If we contain the vapors in the tank, then the pressure increases with temperature. Since the tank weight increases with design pressure, a pressure relief valve is generally provided to prevent the tank from over pressurizing and exploding. When the relief valve releases the pressure, some of the propellant escapes from the tank. This lost propellant is referred to as boil-off loss.  2, record 7, English, - boil%2Doff

In 1979, Boeing and the US Air Force Rocket Propulsion Laboratory proposed a small unmanned "Air-Launched Sortie Vehicle", ALSV consisting of a reusable spaceplane and a huge expendable propellant tank. The vehicle could overfly any point on Earth within 90 minutes of the launch order and also perform other military missions such as satellite inspection. It then returns to a military airbase and lands horizontally like the Space Shuttle.  2, record 9, English, - air%2Dlaunched%20sortie%20vehicle
