Chandrayaan-2 Captures The First Photo Of Moon At A Height Of 2650 Km

Chandrayaan-2 captured the first picture of the moon, which has been shared by space agency ISRO yesterday. Posting the photo of the moon, ISRO wrote: Take a look at the first Moon image captured by #Chandrayaan2 #Vikram Lander taken at a height of about 2650 km from Lunar surface on August 21, 2019.

Take a look at the tweet by ISRO:

The picture shows two important places on the moon, Apollo Crater and Mayer Orientale. At present, ISRO Chairman K.K.  Sivan said on Thursday that the lander with ‘Chandrayaan-2’ currently circling the moon’s orbit, ‘soft landing’ on the lunar surface of ‘Vikram’ will be made in the early hours of September 7. It is currently flying in an elliptical orbit of 118 kms x 4412 kms around the moon. The closest Chandrayaan-2 comes to the moon orbit is 118 kms and the farthest is 4412 kms.

ISRO in a statement said, “Lunar Orbit Insertion (LOI) maneuver was completed successfully today (August 20, 2019) at 0902 hrs IST as planned, using the onboard propulsion system. The duration of maneuver was 1738 seconds. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit. The orbit achieved is 114 km x 18072 km.”

After getting first images from the rover, Isro chairman K Sivansaid, “Rover Pragyan will touch Moon’s surface four hours after Vikram lander lands at 1.55 am on September 7 as the rover will be moving at a speed of 1cm per second. Thereafter, the rover will take one and a half hours more to send images of Moon and lunar data back to Earth via the lander or orbiter as the rover doesn’t have autonomous system. Those images will later be calibrated by Isro and put in public domain. Nasa too can use that data.”

Chandrayaan-2 is India’s second mission to the moon. The mission took off from Satish Dhawan Space Centre at Sriharikota on July 22 which began its journey to the moon on August 14.

“No other mission has landed on the South Pole. They have all landed nearer the Equator of the Moon. But the unique requirement for a landing at the South Pole is that we need to achieve an orbit with an inclination of 90 degrees,” said ISRO chairman K Sivan said.”

“The next major event is on September 2 when we will look at separating the lander from the orbiter. Till now, all the processes are carried out by the propulsion system of the orbiter. From September, it will be carried out entirely on the lander. On September 7, we will start a powered descent on the lander to the Moon’s surface at 1.40am,” said the chairman.
