ISRO Scientists Complete Second Manoeuvre to Push Chandrayaan-3’s Altitude
ISRO scientists on Sunday completed the second manoeuvre around Earth to push Chandrayaan-3’s altitude at the closest point to Earth (perigee) in its current elliptical orbit. This operation was a minor one compared to the first manoeuvre carried out on Saturday. The thrusters onboard the spacecraft were fired for about 42 seconds, and now the perigee of Chandrayaan-3 is around 220km from Earth.
On Saturday, ISRO scientists had completed the first Earth-bound manoeuvre to increase the altitude of Chandrayaan-3 and move it further away from Earth in its journey towards the Moon. This operation was carried out to increase the spacecraft’s apogee (the farthest point from Earth) and lasted for 11-and-a-half minutes.
After Saturday’s manoeuvre, ISRO confirmed that the spacecraft was in a 41762km x 173km orbit. The scientists stated that the spacecraft is healthy and the manoeuvre went as planned. Further analysis of data is being carried out for the next few manoeuvres.
As reported earlier, scientists planned three more operations around Earth on July 18, 20, and 25 to push the spacecraft’s apogee to around 1-lakh-km before attempting to slingshot it towards the Moon on the intervening night of July 31 and August 1.
Summary:
- ISRO scientists completed the second manoeuvre around Earth to increase Chandrayaan-3’s altitude at the closest point to Earth.
- The onboard thrusters were fired for about 42 seconds, and now the perigee of Chandrayaan-3 is around 220km.
- ISRO had completed the first Earth-bound manoeuvre on Saturday to increase the spacecraft’s apogee.
- The next three manoeuvres are planned for July 18, 20, and 25 to push the spacecraft’s apogee before attempting to slingshot it towards the Moon.
