L'ATV effectue une manoeuvre d'évitement pour l'ISS

ISS On-Orbit Status 08/27/08

Conjunction event: Using ATV thrusters, the ISS performed a DAM (Debris Avoidance Maneuver) burn at 12:11pm EDT (in lieu of the IWIS Thruster Firing Test originally planned) to remove the risk of collision with an orbital object,- #33246 (part of the Kosmos-2421 satellite). [Miss distance of the object, tracked over several days, was predicted this morning to be 1.627 km, with a collision probability of 0.0139 (odds 1:72) which brought it over the ruled threshold into the RED box (FR B4-101, i.e.," greater than 1 in 10,000"), requiring a DAM. The burn, calculated to last 5 min 2sec, was performed with two thrusters of the ATV main propulsion system. Predicted delta-V was ~1 m/s, in retrograde direction, so that future Soyuz launch, Soyuz landing and Shuttle ULF2 launch constraints can be met. An automated timer-controlled confirmation check by the RS CCS (Command & Control System) software of the transition to the proper system configuration for the thruster burn did not take place and had to be done manually by MCC-H Flight Control in time for the burn. Note: The last DAM was performed on 5/30/03.]

Mais ce mot, "évitement", est si laid. Pourquoi pas "esquive" ?

Tu cherches la petite bête là... C'est la même chose ;)
