Mars Orbiter Mission update: first apogee-raising burn completed

Posted by Emily Lakdawalla

Topics: Mars Orbiter Mission (MOM), mission status

When the Mars Orbiter Mission launched yesterday, it launched into Earth orbit. Exactly as LADEE recently did, the Mars Orbiter Mission must perform several rocket burns when it is closest to Earth in order to raise the altitude of its apogee (the farthest point of its orbit from Earth). Six of these maneuvers will pump the Mars Orbiter Mission's apogee up high enough that it can perform one more burn while up there to escape Earth's gravity and end up in a heliocentric orbit that will take it to Mars.

The first burn was completed successfully just minutes ago, about 34 hours after launch. Since each new orbit is a little longer than the last, the next burn will not happen 34 hours from now -- it will happen some time later than that. I don't know when each burn is planned for; whenever I know, I'll tell you!

thanks for perfect info, hopefully it will go all the way at end as it is performing now. It is hard to find perfect story on net, since most of media worry about India's demography, media suggesting that if poor don't pay the electricity bill then poor don't deserve solar panel.

Thank you Emily. Congratulations to India! But I noticed not too many females (read: none) in the control room. Still more to do...

Mike Martinez: 11/06/2013 03:26 CST

I've forgotten about an Indian Mars project---has that already occurred---the launching?

Ricardo Bell: 11/06/2013 06:51 CST

Thanks, Emily, for these timely updates. We all very much appreciate your simple graphics and lucid discussions of India's clever orbital tactics.

Here's a tracking link that I found on their Facebook page, posted by a commenter there: http://www.n2yo.com/?s=39370 The track shows it doing a loop, actually going backwards for a bit. I'm guessing that's because it's so high up, at it's apogee, and slowing down so much that the earth's spin overtakes it, relatively speaking. Just a guess. I'd love to be corrected! I have no idea why after the tracking loop the path veers in another direction. Thanks for another great blog post!

The second and third apogee-raising operations would be made on Friday and on Saturday to raise the mission apogee to 40,000 km and 71,650 km respectively. The fourth and fifth operations would be performed to raise the apogee of 1,00,000 km and 1,92,000 km on November 11 and 16 respectively.

Thanks Emily on regular updates on MOM!! Hope India does well success from this mission..still a long way to go !

venkat: 11/07/2013 10:08 CST

Typo error.. Read 'Hope India does well from this mission' from my last comment ! Thanks..

Emily Lakdawalla: 11/07/2013 11:05 CST

madhu and nat: thanks for the info!

@Fred Not sure what images you saw, but the ones I saw had saree-clad women in both the control room and the main hangar/warehouse room where the craft was stored before launch.

Go MOM, go India! Good luck on the way to Mars.

ionthesky: 11/07/2013 03:59 CST

Great post, very informative. Wishing India luck with their Mars program!

Sameer Marathe: 11/07/2013 04:23 CST

Will MAVEN follow a similar pattern (multiple apogee raising burns etc.)? If not is that because it is being launched on a more powerful rocket that is capable of launching it directly in the appropriate orbit towards Mars? What are the advantages/disadvantages of using the strategy that MOM is following?

madhu: 11/08/2013 01:23 CST

The second orbit raising manueour of Mars Orbiter Spacecraft, starting at 02:18:51 hrs(IST) on Nov 08, 2013, with a burn time of 570.6 seconds has been successfully completed.The observed change in Apogee is from 28814 km to 40186 km. http://www.isro.org/mars/updates.aspx

Bernard Isker: 11/08/2013 01:13 CST

Would the trajectory design used by MOM result in greater payload at Mars if used by MAVEN? Hohmann transfer orbits are supposed to be the best but are there others that are better if you trade off time to get to Mars for example?
