Chandrayaan 2 predicts a compressed orbit & # 39; in the last maneuver, reveals ISRO. What does it mean? – Technology News, Firstpost

The second Indian mission to explore the moon, Chandrayaan 2, Just finished a day in its new orbit around the moon. The composite Chandrayaan 2 – the only combined unit consisting of the orbiter, the Vikram lander with the rover nestled inside – succeeded performed one of the four orbital maneuvers around the moon bring the spacecraft within a 100-kilometer radius of the moon's surface.

The Indian Space Research Organization (ISRO) has announced that the spacecraft's planned orbit has been modified – compressed to an elliptical orbit of 114 x 4 412 km (the closest X farthest distance in orbit) from the moon. Originally, the planned orbit at this stage was 121 x 4,303 km. Chandrayaan 2 is now 118 km above sea level, a slight deviation of 3 km from the planned orbit.

But there have been slight deviations from the "planned orbit" at several stages:

• The second orbital climb maneuver was to place C2 over a distance of 250 x 54,689 km (the closest X farthest elliptical orbit around the Earth, but instead places C2 in an orbit of 251 X 54 829 km. [Off by 1 x 140 km]
• The third maneuver for the elevation of Earth orbit aims to place the satellite in a distance of 268 x 71 558 km (the closest X farthest elliptical orbit but instead placed it in an orbit of 276 x 71,792 km. [Off by 8 x 234 km]
• The fourth flight of Earth orbit aims to place the satellite in a distance of 248 x 90 229 km (the closest X farthest elliptical orbit but instead in an orbit of 277 x 89,472 km instead. [Off by 29 x 757 km]
• The final phase of Earth orbit bearing was to place C2 at a distance of 221 x 1.43 585 km (the closest X farthest distance) but was placed in an orbit of 276 x 1.42.975 km. [Off by 55 x 610 km]
• When the C2 composite first entered orbit around the moon on August 20, it was supposed to do so on an elliptical orbit of 118 x 18,078 km, but instead placed in an orbit of 114 km out of 18,072 km. km. [Off by 4 x 6 km]

If "all spacecraft parameters are normal", like ISRO most recent update ad, we have little to fear. The next expected update is scheduled for August 28 between 5:30 am and 6:30 am (Eastern time) and aims to lower the satellite's altitude to 178 x 1,411 km from the Current elliptical orbit of 114 km on 18,072 km.

The mission phase related to the moon, which was 28 days in the previous release schedule has been reduced to 13 days in the current. This is an important part of the orbiter's mission: to stop the monitor for the first time in a year, to ensure that its instruments were not damaged during the voyage, and to thoroughly examine the landing site. of the Vikram lander in the area. the southern polar region of the moon.

In the fourth and final orbital maneuver scheduled for September 1, the Chandrayaan 2 orbital-lander composite is expected to enter a 100-kilometer circular orbit around the moon.
