After Loss of Lunar Orbiter, India Looks to Mars Mission

After giving up on re-establishing contact with the Chandrayaan-1 lunar orbiter, Indian Space Research Organization (ISRO) Chairman G. Madhavan Nair announced the space agency hopes to launch its first mission to Mars sometime between 2013 and 2015. Nair said the termination of Chandrayaan-1, although sad, is not a setback and India will move ahead with its plans for the Chandrayaan-2 mission to land an unmanned rover on the moon’s surface to prospect for chemicals, and in four to six years launch a robotic mission to Mars.
"We have given a call for proposal to different scientific communities," Nair told reporters. "Depending on the type of experiments they propose, we will be able to plan the mission. The mission is at conceptual stage and will be taken up after Chandrayaan-2."
On the decision to quickly pull the plug on Chandrayaan-1, Nair said, "There was no possibility of retrieving it. (But) it was a great success. We could collect a large volume of data, including more than 70,000 images of the moon. In that sense, 95 percent of the objective was completed."
Contact with Chandrayaan-1 may have been lost because its antenna rotated out of direct contact with Earth, ISRO officials said. Earlier this year, the spacecraft lost both its primary and back-up star sensors, which use the positions of stars to orient the spacecraft.
The loss of Chandrayaan-1 comes less than a week after the spacecraft's orbit was adjusted to team up with NASA's Lunar Reconnaissance Orbiter for a Bi-static radar experiment. During the maneuver, Chandrayaan-1 fired its radar beam into Erlanger Crater on the moon's north pole. Both spacecraft listened for echoes that might indicate the presence of water ice – a precious resource for future lunar explorers. The results of that experiment have not yet been released.
Chandrayaan-1 craft was designed to orbit the moon for two years, but lasted 315 days. It will take about 1,000 days until it crashes to the lunar surface and is being tracked by the U.S. and Russia, ISRO said.
The Chandrayaan I had 11 payloads, including a terrain-mapping camera designed to create a three-dimensional atlas of the moon. It is also carrying mapping instruments for the European Space Agency, radiation-measuring equipment for the Bulgarian Academy of Sciences and two devices for NASA, including the radar instrument to assess mineral composition and look for ice deposits. India launched its first rocket in 1963 and first satellite in 1975. The country’s satellite program is one of the largest communication systems in the world.

Didn't they equip the damn thing with a low gain antenna for back up?!
Anyway – onwards to Mars. That's the spirit India!

No sh*t Astrofiend. How about some coarse sun sensors with an onboard ephemeris to at least point it in the general direction of Earth?!! Sheeesh…..let's hope they learned this very simple lesson in spacecraft attitude control: Never trust a star tracker!!!

I would hope they would have thoroughly analyzed what went wrong. Either way you would think they would shoot for the moon again to get it right before attempting the even more technically challenging task of going to Mars.

They are shooting for the moon again. It's called Chandrayaan-2. This time they are adding a rover as well. It is scheduled for launch around late 2013 or early 2014.
