Mars Orbiter Spacecraft in its 100th Orbit around Mars

India’s Mars Orbiter Spacecraft is in its 100th orbit around Mars today (Start : June 22, 2015 End: June 25, 2015). The spacecraft was designed for a mission life of six months in Mars orbit, which was completed on March 24, 2015.  With this, the primary objectives of the Mars Orbiter Mission were realised.

Mars Orbiter spacecraft has outlived its prime mission life and is healthy and operational. The spacecraft, which had earlier entered the ‘blackout phase’ (due to Mars moving behind the Sun from Earth’s perspective), is gradually coming out of that phase.  The spacecraft health data is now being received.  The current elliptical orbit of Mars Orbiter Spacecraft has a periareion (nearest point to Mars) of 474 km and an apoareion (farthest point to Mars) of 71, 132 km.   

The payloads onboard the Spacecraft were last operated in May 2015, and performance of all payloads were satisfactory. Mars Colour Camera (MCC) of the spacecraft had taken 405 frames so far. Operations of all payloads will restart in a few weeks from now.

BENGALURU: The country's low-cost Mars mission spacecraft that is in a rendezvous with the red planet for an extended period has enough fuel for it to last "many years", Indian Space Research Organisation chairman Kiran Kumar said on Friday.

Quote
He said, "still about 45 kg of fuel is left; ...we are hardly using the fuel, fuel requirement is very small."

They were saying they had 37 kg in December.

Then 39 kg two months ago.

I suspect they have a fuel generator on board  ;D

Ah -- so, ISRO has solved ISRU?

Actually, measuring fuel use aboard spacecraft is rather difficult, especially when you start counting stuff in pipework as well as in tanks. It really wouldn't be a surprise if estimates vary, and nor would it be a surprise if they are still wrong. Even long-established spacefaring nations are still pushing the boundaries regarding fuel measurement, so cutting ISRO some slack here seems reasonable. After all, they made it to Mars entirely under their own steam, and they did it the first time they tried - nobody else has *ever* managed that. Kudos!

Image of impact crater located  SW of Huygens crater, taken by Mars Color Camera (MCC) on 04-05-2015 at a spatial resolution of 30 m from an altitude of 576 km.  Complex  impact crater, superimposed over pre-existing crater is clearly seen in this image. This impact crater is having average diameter of 35 km. Terraces of complex impact crater and craters of small diameter distributed in this image are also  seen.

It's amazing how much they are achieving with so little expendature. And for a young agency they have beaten big nations with a Mars success.

Gale crater as seen by Mars Colour Camera on board Mars Orbiter Mission

Gale crater is located near the northwestern part of the Aeolis quadrangle. The crater was named after Walter Frederic Gale, an Australian amateur astronomer of 19th century. Aeolis Mons rises (5.5 km) from the floor of the Gale crater. Gale crater formed when a meteor hit Mars in its early history, about 3.5 to 3.8 billion years ago. This image is taken by Mars Colour Camera on January 17, 2015 at an altitude of 9004 km with a resolution of 468 m.

I wish they take a few more global snaps of Mars. It may not matter much in terms of science, but would be awesome.    ;)

Announcement of Opportunity for utilising Mars Orbiter Mission data from MCC, TIS, MSM, LAP and MENCA payloads (MOM-AO)

Indian Space Research Organization (ISRO), Department of Space (DOS), Government of India, announces an opportunity (AO) to carry out scientific research using data from Mars Orbiter Mission (MOM). MOM is ISRO’s first interplanetary space probe dedicated for the Mars research. This AO is targeted towards utilizing the data from five payloads of MOM, namely Mars Colour Camera (MCC), Thermal Infrared Imaging Spectrometer (TIS), Methane Sensor for Mars (MSM), Lyman Alpha Photometer (LAP) and Mars Exospheric Neutral Composition Analyser (MENCA).


Who can submit a Proposal?

Proposals could be submitted by individuals or a group of scientists, academicians belonging to recognized institutions, universities and government organizations of India. Only those having at least a minimum remaining service of four years before superannuation are eligible to lead the project as PI/Co-PI. The proposals must be forwarded through the Head of the Institution, with appropriate assurance for providing necessary facilities for carrying out the AO project.

3D portrayals of Ophir Chasma terrain.

The image taken by Mars Colour Camera over Ophir Chasma,a canyon in the Coprates quadrangleof Mars at 4° south latitude and 72.5° west longitude.  The word chasma has been designated by the International Astronomical Union to refer to an elongate, steepsided depression. Ophir Chasma is part ofthe largest canyon system in the solar system known as vallesmarineris. The walls of the chasma contain many layers and the floors contain large deposits of   layered materials.  This image is taken on 19th July 2015 at an altitude of 1857 km with a resolution of 96 m.

Here ya go.
Very low res.

four images of Deimos about 12 seconds apart at 13:06 UT on October 14, 2014. The images have a resolution of about 300 meters per pixel; Deimos is roughly 13 kilometers wide.

...enlarged them 400% and stacked them to try to make something of them. If nothing else, the stacking reduced the artifacts of the Bayer color interpolation in the originals.

Oh, those, okay.  Those have been around for several months.  I thought the post was about something actually new, this is not the case.  No wonder the article didn't include pics, it was just an article about the ISRO MOM team congratulating themselves for something they actually released a while ago.

As Emily Latella would say, never mind...   ;)
