Mars Orbiter Mission ready to fly onward from Earth to Mars

Topics: Mars Orbiter Mission (MOM), mission status

Just a quick update: Today is the day when India's Mars Orbiter Mission will fire its rocket to depart Earth and begin its 300-day journey to Mars. The rocket burn begins on December 1 at 00:49 IST (today at 19:19 UT / 11:19 PT). According to a Press Trust of India article, the 440-Newton Liquid Apogee Motor will fire for 23 minutes, adding 648 meters per second of velocity, consuming 198 kilograms of fuel. The latest mission status update says all is going well: "Performance assessment of all subsystems of the spacecraft has been completed. MOM is now ready for Trans-Mars Injection."

The plan includes four trajectory correction maneuvers, the first happening on December 11 (this still according to the Press Trust of India article). The rest are in April 2014, August 2014, and then 10 days before orbit insertion in September 14.

The situation is being monitored from their mission control at ISRO's Telemetry, Tracking and Command Network (ISTRAC) in India. I will be keeping my eye on the Mars Orbiter Mission Facebook page to learn about the status of this most crucial maneuver -- that seems to be the place that posts Mars Orbiter Mission news first. Best of luck to ISRO!

What will happen if Space craft fail to get into Mars orbit?

Shreerang Kaulgi: 11/30/2013 11:39 CST

Will Maven and MOM be travelling at about the same speed when they near Mars for orbit injection burns? If that is so, Maven will require greater reverse thrust than MOM. So it is carrying more fuel? What is approximate speed of Maven and MOM as compared to Mars in its orbit around the Sun? Can a Hohmann orbit be designed so that speed at the apoapsis is about same as that of the target space body?

Shreerang Kaulgi: 11/30/2013 12:18 CST

I read that Maven will get only one chance to enter Mars orbit but MOM will get more than once. Is this correct? Why would be it be so?

Shreerang Kaulgi: 11/30/2013 12:59 CST

is the Earth View from correct? Also is the live tracking from correct? Both were showing MOM far away from Perigee as of 00:30 on 01 Dec2013.

Shreerang Kaulgi: 11/30/2013 01:45 CST

Just heard that thruster burn is complete and the required incremental velocity is imparted. Hop that both crafts will progress as planned and operate in a complementary manner.

Shreerang Kaulgi: 11/30/2013 01:53 CST

Pardon me for a spelling error in "Hop", should be "Hope".

Transmartian injection has been declared succesful. MOM is on the path to mars. First trajectory correction maneuver is on December 11th.

The n2yo and sat flare sites do not do truly real time tracking but use TLE's to estimate position and are totally wrong.

mangalyaan definitely reach the mars

sanju: 01/07/2014 02:47 CST

Isro successfully launch 4th interplanetary MARS orbit mission ,to design & realise a spacecraft which can reach martian transfer Trajectory, around the mars mapping minerology & sensing Methane sensor by payloads.Now update result Mars mission is under good working condition.congractulate All Isro luck for next stage while mars orbit nearest point....*****
