Chandrayaan 2 gets closer to moon, enters second of the 5 planned orbits

Published

on

Scientists at Indian Space Research Organisation performed the second of the five planned orbit-raising manoeuvre of Chandrayaan-2 in the Earth’s orbit early Friday morning.

The on-board propulsion system was fired to increase the apogee or the point on the elliptical orbit farthest from the Earth at 01:08 am.

Isro scientists were able to forgo the first orbit raising manoeuvre planned for the day after lift-off as the GSLV Mark III “over-performed” placing the spacecraft at an orbit about 6,000 km higher than intended. This would save fuel for the spacecraft, which can be used to “play around with the manoeuvre” Isro chairperson K Sivan had said after the launch.

The orbit of Chandrayaan 2 was increased to a 251 x 54,829 km from the 230 x 45,163 km it was in after the first manoeuvre. Three more “burns” or firing of the propulsion system will be carried out to reach the final orbit of 221 x 1,43,585 km on August 6.

The first manoeuvre on Wednesday was to raise the perigee or the point on the elliptical orbit closest to the Earth.

The spacecraft is scheduled to reach a lunar orbit of August 20.

“Although we have given the intended orbits for the next four manoeuvres, with each burn the numbers are likely to change. This is a very dynamic process. There is a team that recalculates the orbit every hour, there is round-the-clock simulation to plan for the next move. This is not like a launch vehicle in which we cannot make changes once launched. The spacecraft is in our control and we need to guide it to the intended orbit to escape Earth’s orbit,” said an official from Isro who asked not to be named.

Four more burns would be carried out in the lunar orbit to lower the spacecraft into a circular 100x 100 km orbit around the moon with a two-hour orbital time or time taken for the satellite to complete one orbit.

After this, the lander-rover will separate and move to a 100x30km orbit. During this period, the optical high-resolution camera on-board will be turned on to scout for a suitable landing site in the lunar south pole.

The images taken will be transmitted to Earth and processed after which the landing site map will be uploaded to the lander-rover before its powered descent to the moon on Sept 7 at 2.58am.

At 2.43pm on July 22, the 14-storey-tall GSLV Mark III rocket blasted off from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota with the 3,850kg Chandrayaan-2 spacecraft. Isro scientists at the Indian Space Research Organisation had a narrow one-minute window for their second attempt at launching the moon mission, a week after the first attempt was aborted just short of an hour before lift-off due to technical snag.

The matter of demanding the right of worship in the Qutub Minar complex is once again in discussion. In fact, the Saket court has reserved its decision on the reconsideration petition filed in the matter. Delhi’s Saket court will pronounce its verdict on December 12.

This reconsideration petition was filed by petitioner Kunwar Mahendra Dhawaj Prasad in Saket Court. In fact, the Saket court had rejected the petitioner Kunwar Mahendra Dhawaj Prasad’s petition in the matter of ownership of Qutub Minar. Kunwar Mahendra Dhawaj Prasad Singh had filed a petition claiming ownership over Qutub Minar.

By filing the first petition, Mahendra Dhawaj Prasad Singh had demanded to make himself a party in this matter. It was said in his petition that the government had taken over the entire property in 1947 without our permission. This petition was rejected by the court.

The last time in September, when the ASI’s lawyer opposed the petition of Kunwar Mahendra Dhawaj Prasad Singh, saying that Sultan Begum had claimed the ownership rights over the Red Fort, we had opposed that petition in the Delhi High Court. Even then the court had accepted that there is no basis for the demand made in the petition. ASI had requested to dismiss the petition of Kunwar Mahendra Dhawaj Prasad Singh.

According to police, a 45-year-old man was arrested on Thursday for allegedly murdering his 35-year-old live-in partner at her rented house in Ganesh Nagar, West Delhi. According to police, the woman’s 16-year-old daughter was asleep in another room at the time of the incident.

According to the police, the victim, Rekha Rani, had lived in Ganesh Nagar with her daughter for more than 15 years, and the partner, Manpreet Singh, had stayed with them for the past 7-8 years.

According to police, Manpreet gave Rekha’s migraine patient daughter some pills and told her to go to sleep on December 1 at around 6 a.m.

“He informed her that her mother had gone to the market when she became suspicious and inquired about her mother. She called her cousin and went to his Paschim Vihar home. They then called the police when they discovered that their house in Ganesh Nagar was locked. Ravindra Singh Yadav, Special CP (Crime Branch), stated, “The victim’s daughter stated in her statement that she suspected that Manpreet had harmed her mother and that Manpreet and her mother had been fighting over money for some time.”

According to the police, the suspect allegedly stabbed Rekha in the neck and face while she resisted and mutilated a finger on her right hand.

Manpreet moved in with Rekha after meeting her in 2015. He claimed that Rekha stopped letting him visit and talk to his family because, over time, she started to feel insecure. A police officer stated, “He purchased a chopper (cleaver knife) recently to murder her and planned to kill her.”

According to the police, the accused is allegedly involved in six cases in Delhi, including kidnapping for a ransom, an attempt to kill, the arms act, and forgery.

According to the police, the suspect drove to his home village of Nabha in Punjab after killing the woman. Police said the car was found through toll barriers and he was caught using technical investigation.
