Doug, it's been pointed out to me that I made some errors in the paragraph about the GSLV; I've edited my original post slightly. Sorry about that. (GSLV has had successful flights, though not many; recent failure had to do with a cryogenic upper stage). This article says that orbit altitude will vary from 385 to 80,000 km, FWIW. That apoapsis is roughly 4 times farther from Mars' center than Deimos' orbit. Okay! Thanks, Emily. In theory, Mangalyaan could come fairly close to Deimos. In practice, hoot, who knows. I would imagine that if they arrive in Mars orbit with a little bit of fuel left to play with, a Deimos flyby would at least be discussed. The gentleman in the article is upset because Mangalyaan is turning out to be more of a technological proof-of-concept than an actual scientific mission. And I can see the force of that. On the other hand, there's precedent; Pathfinder and Sojourner were test beds for lander and rover technology. (As it turned out, they ended up performing much better than expected and delivered some respectable science.) Doug M. |

It seems that the Thermal Infrared Imaging Spectrometer (TIS) has a spectral range of 7-14 μm and a spectral resolution of 580 nm (THEMIS: 6.8-14.9 μm and ~1 μm, respectively). Bhatt et al., 2013

From the Deccan Herald today:
"“We hope to observe Phobos, but not the other one, Diemos, as it is too tiny,” V Adimurthy, senior adviser of interplanetary missions at Isro, told Deccan Herald." Too bad - Phobos is very well imaged already, Deimos is poorly covered by images especially at high resolution. We really need to see more of it. Even the shape model is very uncertain on the trailing side. China's ill-fated orbiter launched with Phobos-Grunt was going to look at it (I was told personally by a person involved with it). Maybe we will have to wait for the next Chinese orbiter suggested to fly in 2018. Phil -------------------- ... because the Solar System ain't gonna map itself.

Is there a link to the webcast? It's t-7 hours, and the facebook page mentions there will be one, but the ISRO site just shows an old link...

The website says the webcast will begin at 14:00 IST, which is to say, not for roughly 5 hours.

I see it now; thanks. Now to wait.
Amazing that a Mars probe can go from first announcement to launch day in only three pages on this of all forums! (not a criticism of anyone, just noting a consequence of the lack of info until the past few weeks) |

Yeah. I do have to say that they're making up for lost time with their Facebook page. Lots of info and high-resolution photos.

Spaceflightnow has the stream starting.
Definitely a different vibe on the preshow from NASA press conferences |

FYI. I'm finding the mobile video stream from spaceflightnow much more reliable than the desktop feed which was very glitchy for me.

Liftoff!
And coasting... Hope to see good news tomorrow morning. |

So far so good. The liquid fueled fourth stage has ignited. Hopefully everything works...

Successfully made initial parking orbit, looking good thus far.

(not a criticism of anyone, just noting a consequence of the lack of info until the past few weeks) It hasn't attracted a lot of attention in mainstream media, either. I'd say this is one part India having been rather tight-lipped (reasonable, given that it's their first effort and fingers are crossed) and two parts it not fitting any convenient narrative. India launched a Mars probe... wait, India? Huh? (Prediction: if China's Moon landing succeeds next month, we will see much, much more media coverage. Because that's going to fit a couple of different narratives really well.) Doug M. |
