With drained battery and no fuel, India’s ‘Mangalyaan’ mission comes to an end | India News

Bengaluru: India’s Mars Orbiter craft has run out of propellant and its battery drained past the protected restrict, fuelling hypothesis that the nation’s maiden interplanetary mission ‘Mangalyaan’ could have lastly accomplished its lengthy innings. The Rs 450 crore Mars Orbiter Mission was launched onboard PSLV-C25 on November 5, 2013, and the MOM spacecraft was efficiently inserted into Martian orbit on September 24, 2014, in its first try.

“Proper now, there is no such thing as a gas left. The satellite tv for pc battery has drained,” sources within the Indian House Analysis Organisation (ISRO) instructed PTI. “The hyperlink has been misplaced”.

There was, nonetheless, no official phrase from the nation’s nationwide house company, headquartered right here.

With gas on board, ISRO had been performing orbital manoeuvres on MOM spacecraft to take it to a brand new orbit to keep away from an impending eclipse up to now.

“However just lately there have been back-to-back eclipses together with one which lasted seven-and-half hours,” officers stated on situation of anonymity, noting that every one the propellant on board the ageing satellite tv for pc had been consumed.

“Because the satellite tv for pc battery is designed to deal with eclipse period of solely about one hour and 40 minutes, an extended eclipse would drain the battery past the protected restrict,” one other official stated.

ISRO officers famous that the Mars orbiter craft functioned for nearly eight years, properly past its designed mission lifetime of six months.

“It has carried out its job and yielded important scientific outcomes,” they stated.

The aims of the mission have been primarily technological and included design, realisation and launch of a Mars Orbiter spacecraft able to working with enough autonomy in the course of the journey part; Mars orbit insertion/ seize and in-orbit part round Mars.

The MOM — a know-how demonstration enterprise — carried 5 scientific payloads (complete 15 kg) gathering knowledge on floor geology, morphology, atmospheric processes, floor temperature and atmospheric escape course of.

The 5 devices are: Mars Colour Digicam (MCC), Thermal Infrared Imaging Spectrometer (TIS), Methane Sensor for Mars (MSM), Mars Exospheric Impartial Composition Analyser (MENCA) and Lyman Alpha Photometer (LAP).

“MOM is credited with many laurels like cost-effectiveness, quick interval of realisation, economical mass-budget, and miniaturisation of 5 heterogeneous science payloads”, ISRO officers identified.

Extremely elliptical orbit geometry of MOM enabled MCC to take snap pictures of ‘Full disc’ of Mars at its farthest level and finer particulars from closest level.

The MCC has produced greater than 1000 photographs and printed a Mars Atlas.

In the meantime, plans on a follow-on ‘Mangalyaan’ mission to the crimson planet, nonetheless, are but to be firmed up.

ISRO got here out with an ‘Announcement of Alternative’ (AO) for future Mars Orbiter Mission (MOM-2) in 2016 however officers acknowledged that it is nonetheless on the drafting board, with the approaching

‘Gaganyaan’, ‘Chandrayaan-3’ and ‘Aditya – L1’ initiatives being within the house company’s present precedence listing.

The AO had stated: “It’s now deliberate to have the subsequent orbiter mission round Mars for a future launch alternative. Proposals are solicited from scientists inside India for experiments onboard an orbiter mission round Mars (MOM-2), to handle related scientific issues and subjects.”

“Not within the authorized listing as of now”, a senior ISRO official instructed PTI on being requested about an replace on the MOM-2.

“We have to formulate the challenge proposals and payloads primarily based on the broader session with the analysis neighborhood,” the official stated. “It is nonetheless on the drafting board. However wants some extra particulars and worldwide collaboration for finalising the mission.”
