I think its very unlikely that a comet will stop ISRO launching the probe. More likely are technical problems on the ground.

True. It's a very tight schedule they have set themselves, reminds me of the early days of Soviet interplanetary exploration.

Well, like Tito & Co, they are racing to meet a planetary alignment deadline.

Maybe flying to Mars is easier than I thought.....  :P

ISRO ponders delaying Mars mission over fears of comet:

Well if the reporters aren't exaggerating (somehow I think they are though  ::)) then someone at ISRO needs to be fired for using bizzare reasons for delaying a mission, either for cover up of other schedule delays or not using common sense.

Curious doesn't seem to bothering NASA or ESA and their craft.

I took a look at the article - the reason given is hilarious: the methane sensor (one of the science instruments on board) may have recorded those CH4 et al. particles from the comet tail instead of Mars, thus contaiminating the data. Seriously - that's a problem!? That spacecraft may have the closest pass to the comet of all Mars orbiters - by far, and the Indians think that's an issue? They are actually in the prime position for gathering some data on the comet by luck.....

Can any experts on trace gas detection shed some light on the excuse?

Mars Orbiter on track, comet no deterrent: ISRO chief

http://timesofindia.indiatimes.com/home/science/Mars-Orbiter-on-track-comet-no-deterrent-Isro-chief/articleshow/19606336.cms

Yeah, the explanation in the article above is lousy at best....

Wondering if it actually shows that the final testing is behind schedule a la Phobos Grunt in 2009.....  ::)

I don't know where you're going, man. If they've made an announcement, it's to quell speculation. The previous article that I posted before about the comet was itself just speculation, and not citing any named source at ISRO. That happens a lot in the Indian media - pretty routine.

Anyway, I'll keep my fingers crossed for November, and we'll see how things work out.

Same here. Even from the science return perspective this mission may return some new information on Mars (methane trace gases), not to mention this may serve as a benchmark on the Indian ability to develop and operate complex spacecrafts.

BTW I have seen many names for the spacecraft - is the "Mangalyaan" moniker unofficial?

Haha, I think it depends on who one talks to.

In the wake of Chandrayaan ( "Chand" = Moon, "yaan" = chariot/craft), when the Mars mission was announced, then some watchers took to a similar naming convention ("Mangal" = Mars). So the nickname "Mangalyaan" was adopted.

But I think people at ISRO formally call it "Mars Orbiter Mission" (MOM).

But yeah, I think methane results would be useful to corroborate against what NASA will get from its latest MAVEN probe. Multiple sources of data are best.

It's too bad that ISRO won't be able to try another bistatic test with NASA, as was attempted between Chandrayaan and LRO (didn't work out due to Chandrayaan system failure under lunar-reflected radiation).
Bistatic radar response would be an excellent way to find water ice, due to its unique signature.

Oh well, hopefully some future missions will attempt this. In order to produce a detailed map of Martian ice.

IIRC, the November 27 date is actually the day the spacecraft should made its final TMI burn. Since it needs several burns to get it out of Earth's orbit, I suggest keeping the October date for the launch itself.

Yeah I saw that one - but I specifically remember an earlier news report that gave the October 25 launch date with November 27 as the TMI burn date - you might check the earlier posts here for confirmation.

OK, let's try October again: an official from ISRO recently said that "the satellite is expected to exit the Earth orbit on November 26/27"

Thanks Sanman! The article says the following about the launch date:

“We will have to launch the rocket on October 22, so that it can depart the Earth's orbit on November 26 and enter the Martian orbit on September 21, 2014.”
