On 12th November, Chandrayaan-1 spacecraft has successfully reached its intended operational orbit at a height of about 100 km from the lunar surface. This followed a series of three orbit reduction manoeuvres conducted during the past three days by repeatedly firing the spacecraft’s 440 Newton Liquid Engine. As part of these manoeuvres, the engine was fired for a cumulative duration of about sixteen minutes. As a result of these manoeuvres, the farthest point of Chandrayaan-1’s orbit (aposelene) from the moon’s surface was first reduced from 7,502 km to 255 km and finally to 100 km while the nearest point (periselene) was reduced from 200 km to 182 km and finally to 100 km. continue reading…
