I think the title of this thread strongly indicates that the Great Galactic Ghoul is still digesting Beagle 2.

This is an awesome accomplishment from India, now lets see Chandrayaan-2 make it to 2016 !

ISRO's Mars Orbiter outlives original lifespan of 6 months, completes 1000 days in orbit

India's Mars Orbiter Mission (MOM) completed 1000 earth days in its orbit which is beyond its designed mission life.
Indian Space Research Organisation's maiden interplanetary mission was designated to last only for six months but it outlived its lifespan. MOM was launched on November 5, 2013 by PSLV-25 and it entered the Martian orbit on September 24,2014.
The mission's success received applause from across the world as it was able to enter the red planet's orbit in its first attempt and was cost-effective when compared to missions launched by NASA and the European Space Agency.

Congratulations to ISRO and all the team for this fantastic achievement.

 Mangalyaan has now( as of May 30/2018)  been in orbit for 3 years, 8 months and 6 days. Not bad for something that was originally projected to last 6 months!  Question for those with more detailed knowledge: Is the orbit of Mangalyaan novel i.e is this the first time a Mars satellite has been in such an orbit. I do remember reading somewhere that almost all Mars missions placed their respective satellites in a polar orbit, whereas Mangalyaan is in an ellipitical or equatorial path. And it thereby can provide full disk images of the planet.

And with the alteration of the orbit because of the eclipse, is this new orbit( more tilted toward the Sun, I believe)  also quite different, with images that are rare, if not novel?

Most other Mars orbiters had the role of mapping Mars at higher resolution than global full-frame images allow, and needed a near-polar orbit to provide global coverage.  You are right that this low inclination orbit is rare.  The Hope mission from UAE will also have a low inclination orbit.  The global-scale images, planet in a single frame, could still be obtained from a near-polar orbit if the periapsis is large (USSR's Mars 3).  MOM's images of the whole planet are beautiful and probably useful for mapping cloud and dust activity, though we have MARCI on MRO for that as well. 

Easy access to MOM images:

 Thank you Phil Stooke!  Nice to see well informed comments on the Mangalyaan. What prompted my query was reading some hideously awful  messages from years gone by on the Mars Orbiter. There are small, petty, jealous people out there who are belittling or dismissing the achievement of ISRO using specious and silly arguments.  A few, mercifully not many, are even Indian!

The Indian orbiter should be in a good orbit for getting pictures of the current global dust storm. They might be better than the NASA ones because they are taken from a higher altitude. However, the pictures from this spacecraft seem to be quite infrequent and there is a long delay before release.

What is the chance that the Indians have taken a good picture of this storm? Will they wait a couple of years to release it?
