After providing 13. 5 years of highly successful telecommunications services for Eutelsat, ECS-1 was switched off on 16th of December. By then, the satellite launched on 16 June 1983, had been transmitting for a total of 716 584 hours(cumulative TWTA hours). Over a two-week period, a series of end-of-life tests, and 11 re-orbiting manoeuvres which led to the complete depletion of the spacecraft's hydrazine tanks, were performed.

A rocket propellant consisting of a single substance, especially a liquid, capable of creating rocket thrust without the addition of a second substance.  3, record 12, English, - monopropellant

Record number: 12, Textual support number: 1 CONT

A monopropellant is a chemical propulsion fuel which does not require a separate oxidizer. A rocket engine which is based on a monopropellant requires only one fuel line instead of a fuel and an oxidizer line. The "mono" in monopropellant means singular - a fuel that can function alone. A chemical propulsion system that combines like hydrogen and oxygen would be a bipropellant. A monopropellant burns by itself because the oxidizer is bound into the molecule itself. This makes the rocket engine lighter, less expensive, and more reliable. Monopropellant designs are typically used in control thrusters but not in actual propulsion units.  4, record 12, English, - monopropellant

Record number: 12, Textual support number: 2 CONT

The most commonly used monopropellant is hydrazine(N2H4), a chemical which is characterized as "strongly reducing". The most common catalyst is granular alumina coated with iridium(aka. Shell-405). There is no igniter with hydrazine. Shell 405 is a spontaneous catalyst, that is, hydrazine decomposes on contact with the catalyst. The reaction is highly exothermic and produces an 1800°F(1000°C) gas that is a mixture of nitrogen, hydrogen and ammonia. Another monopropellant is hydrogen peroxide, which, when purified to 90% or higher concentration, is self-decomposing at high temperatures or when a catalyst is present.  5, record 12, English, - monopropellant

The satellite's integral propulsion system uses monomethyl hydrazine and nitrogen tetroxide bipropellant carried in four spherical titanium tanks. A single 490-newton(110-pound force) thruster is used for perigee augmentation and apogee burns, and thirteen 22-newton(5-pound force) thrusters are used for attitude control and stationkeeping maneuvers. Highly accurate antenna pointing control is provided by independent beacon tracking on each of the Ku-band reflector systems. The attitude control system uses an innovative combination of double-gimballed momentum wheels and magnetic field torquing, which minimizes the need for thruster use during normal on-station operations.  3, record 22, English, - double%2Dgimballed%20momentum%20wheel

Technique de séquençage qui utilise des réactions chimiques interrompant spécifiquement la chaîne de DNA en position A, T, G ou C. Ainsi le DNA, marqué à son extrémité 5' par le 32_P, est dégradé partiellement et spécifiquement au cours de quatre réactions séparées. L'électrophorèse de ces produits de dégradation sur les gels de polyacrylamide mis au point chez Sanger, suivie d'une autoradiographie, permet la lecture directe de la séquence de DNA.  4, record 24, French, - m%C3%A9thode%20de%20Maxam%20et%20Gilbert
