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 spacecrafts third orbit
raising manoeuvre today (October 26, 2008) morning.
During this manoeuvre which was initiated at 07:08 IST, the spacecrafts 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.
