After 8 years of hard work, India’s Mangalyaan ran out of fuel: report

Bangalore:

India’s Mars Orbiter has run out of fuel and its battery has reached its safety limit, fueling speculation that the country’s first interplanetary mission ‘Mangalyaan’ may have finally completed its long roles.

The Rs 450 Crore Mars Orbiter mission was launched aboard PSLV-C25 on November 5, 2013, and the MOM spacecraft was successfully inserted into Mars orbit on September 24, 2014 in its first attempt.

“For now, there is no more fuel. The satellite’s battery has run out,” Indian Space Research Organization (ISRO) sources told PTI. Link lost.

However, no official word has come from the country’s national space agency, which is based here.

With fuel on board, ISRO was performing orbital maneuvers on the MOM spacecraft to move it to a new orbit to avoid an impending eclipse in the past.

“But recently there have been consecutive eclipses, including one that lasted seven and a half hours,” said the officials, who requested anonymity, noting that all of the propellant aboard the old satellite had been used.

“As the satellite’s battery is designed to support an eclipse duration of only 1 hour and 40 minutes, a longer eclipse will drain the battery beyond the safe limit,” another official said.

ISRO officials noted that the Mars Orbiter has been in operation for about eight years, well beyond the six-month life of its projected mission.

“He did his work and achieved important scientific results,” they said. The mission’s objectives were primarily technological and included the design, completion and launch of a spacecraft to Mars capable of autonomously operating during the flight phase; Enter/capture Mars orbit and stage in orbit around Mars.

MOM – a technical pilot project – transported five scientific payloads (15 kg in total) to collect data on surface geology, morphology, atmospheric processes, surface temperature and atmospheric escape process.

The five instruments are: the Mars Color Camera (MCC), the Thermal Infrared Imaging Spectrometer (TIS), the Mars Methane Sensor (MSM), the Mars Extra Atmospheric Neutral Composition Analyzer (MENCA) and the Lyman Alpha Photometer (LAP).

ISRO officials noted that “MOM has many achievements, such as cost-effectiveness, short response time, collective economic budget, and the miniaturization of five heterogeneous science payloads.”

MOM MCC’s highly elliptical orbit geometry allowed for quick snapshots of the “full disk” of Mars at its farthest point and finer detail from its closest point.

The MCC produced over 1,000 images and published an atlas of Mars.

Meanwhile, plans for the “Mangalyaan” mission to the red planet have yet to be confirmed.

ISRO made an “Announcement of Opportunity” (AO) for a future Mars Orbiter (MOM-2) mission in 2016, but officials acknowledged it was still on the drawing board, with “Gaganyaan” and “Chandrayaan-3” appearing and “Inclusion of the Aditya – L1 projects is on the space agency’s current priority list.

AO said: “The next Mars Orbiter mission is now planned to allow for a future launch opportunity. Proposals were solicited from interested scientists in India to conduct experiments aboard the Mars Orbiter Mission-2 (MOM-2), to address relevant scientific information. Problems and topics.” “It’s not on the approved list yet,” a senior ISRO official told the PTI when asked about an update to the MOM-2.

“We need to formulate project proposals and payloads based on broader consultations with the research community,” the official said. “It’s still on the drawing board. But it needs more details and international cooperation to finish the job.”
