1000 Earth days corresponds to 973.25 Mars Sols (Martian Solar day) and MOM completed 388 orbits.

India's maiden interplanetary mission ofIndian Space Research Organisation (ISRO) Mars Orbiter Mission (MOM) has completed 1000 earth days in its orbit, today. Scientific analysis of the datareceived from the Mars Orbiter spacecraft is in progress. The mission of ISRO, which was launched on November 5, 2013, by PSLV-C25, an expandable launch system, entered the Martian orbit on September 24, 2014, in its first attempt.

The satellite is in good health and continues to work as expected.

Citing surplus fuel as the reason, ISRO in March, 2015 had first announced that the spacecraft's life was extended for another six months. Later in June, 2015 its Chairman A S Kiran Kumar had said it has enough fuel for it to last "many years".

The Mars Orbiter has five scientific instruments - Lyman Alpha Photometer (LAP), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA), Mars Colour Camera (MCC) and Thermal Infrared Imaging Spectrometer (TIS).

The MOM went through a communication "blackout" as a result of solar conjunction from 2 June 2015 to 2 July 2015.

MOM spacecraft experienced the "whiteout" geometry between 18 May and 30 May 2016.

On January 17, this year, the Mangalyaan performed a manoeuvre to migrate from its original orbit to avoid a risky 8-hour eclipse that threatened to destroy the satellite by draining it of its reserve battery.

Besides this, ISRO had also launched MOM Announcement of Opportunity (AO) programmes for researchers in the country to enable them to use the data retrieved from the orbiter for research and development objective. The success of Mars Orbiter Mission hasmotivated India's student and research community in a big way.Thirty-two proposals were supported under this AO.
