标  题: ISRO: Chandrayaan-1 enters Deep Space
发信站: BBS 未名空间站 (Sun Oct 26 07:10:01 2008)

October 26, 2008  

Chandrayaan-1 spacecraft has entered deep space after crossing the 150,000
km (one and a half lakh km) distance mark from the Earth. This happened
after the successful completion of the spacecraft’s third orbit raising
manoeuvre today (October 26, 2008) morning.

During this manoeuvre which was initiated at 07:08 IST, the spacecraft’s
440 Newton liquid engine was fired for about nine and a half minutes. With
this, Chandrayaan-1 entered a much higher elliptical orbit around the Earth.
The apogee (farthest point to Earth) of this orbit lies at 164,600 km while
the perigee (nearest point to Earth) is at 348 km. In this orbit,
Chandrayaan-1 takes about 73 hours to go round the Earth once.

The antennas of the Indian Deep Space Network at Byalalu are playing a
crucial role in tracking and communicating with Chandrayaan-1 spacecraft in
such a high orbit. The spacecraft performance is normal. More orbit raising
manoeuvres are planned in the coming few days to take Chandrayaan-1 towards
the Moon.
