ISRO’s Mars mission completes 5 years

 

Mangalyaan Mission completed five years on Tuesday. “It’s working and constantly sending photos. There’s still some time left,” Mr. Sivan said.

When asked about ‘Mangalyaan 2’, he said that work is going on and no decision has been taken yet.

An official of the Indian Space Research Organization (IRSO) said that Mars Orbiter has sent a total of thousands of photographs of two terabytes.

The Mars Color Camera captured near-distance images of Phobos and Deimos, the two moons of Mars. ISRO stated that MOM is the only Mars artificial satellite that can capture the full disk of Mars in a visible frame as well as take distant images.

MOM data helped produce 23 publications in peer-reviewed journals.

An important conclusion of the mission has been that dust storms over the Martian can extend up to hundreds of kilometers, said AS Kiran Kumar, Mr. Sivan’s predecessor.

Mangalyaan’s success has come in the wake of ISRO’s setback to the Chandrayaan 2 mission, being cheaper than the Hollywood film “Gravity” and NASA’s Maven Orbiter. The Maven Orbiter was similar to India’s Mars mission.

Mangalyaan is India’s first attempt to reach another planet successfully. The launch vehicle, spacecraft and ground segment cost Rs. 450 crores Rs. A life-limiting parameter of a spacecraft under nominal orbital conditions is fuel availability, which is necessary to maintain the spacecraft’s orbit and orientation. In the case of MOM, scientists said some reserve is propellant.

“The orbiter may last another year,” Mr. Kumar told the Press Trust of India.

Giving details of how fuel was saved, Mr. Kumar said: “Non-nominal performance” was kept for various segments while planning the mission. “Depending on whether we provide a certain type of fuel for improvement to overcome those non-nominal objectives,” Mr. Kumar said.

Since the launch was perfect, he said, the mission had the full benefit of “fields of fuel”.

“This was the first time we were going beyond the Earth’s gravitational field. During that period, you could face a non-normal situation that could be called for improvement and to make sure that something was repetitive. Will require operations.

“We were able to perform all the steps without any hiccups and we were able to reach Mars orbit without additional fuel consumption. Entry into the Martian orbit was also very well closed, helping to save fuel. “

There were instances when the fuel was consumed for correctional purposes to avoid the orbiter being exposed to foggy dust. Former ISRO Scientific Secretary, Krishna Murthy YVN said, “It also reflects good mission management.”

Elaborately, Mr. Murthy stated that the precise location of the satellite by the ground station helped conserve fuel. At the same time, effective control management also helped to extend the life of MOM.

Mr. Murthy said that giving another example of ISRO satellite’s own life, Cartosat-1, the first Indian remote sensing satellite capable of providing in-orbit stereo images, was planned for three years but 10 years Continued to perform till The satellite was launched in 2005.
