Indian space scientists have corrected the orientation of the country's first lunar spacecraft Chandrayaan-1 after one of its sensors malfunctioned, a senior official said Friday.

"We have overcome the snag and the spacecraft is again able to look at the lunar surface while orbiting at about 200 km above the moon" - Indian Space Research Organisation (ISRO) director S. Satish.

The Indian space agency has raised the orbit of its first unmanned lunar spacecraft Chandrayaan-1 to 200km from the lunar surface for further studies on orbit perturbations and gravitational field variations of the Moon.

India's Moon mission - Chandrayaan-1 - is certainly making strides in the time it has been around the Moon. After revealing traces of iron deposits and formation of craters recently, it is now throwing up pin-point evidence on the evolution of the Moon.
Forty years after the American Apollo Mission, Chandrayaan-1 has revealed direct evidence on the formation of crusts/highlands on the Moon.

Chandrayaan's first image of Earth in its entirety
From its firm perch in the lunar orbit, Chandrayaan-1 has sent back its newest images, one of them being its first full-Earth image captured in late March by the Terrain Mapping Camera (TMC) on board.
These images, taken from 4,00,000 km away, with India at the centre, shows Asia and West Asia, parts of Africa and Australia forming a terrestrial ring round the Indian Ocean. Soon after its launch last October, Chandrayaan captured images of a partial Earth taken from closer ranges: 9,000 and 70,000 km away from Earth.

Chandrayaan-I Moon Impactor Probe
Permalink  
 

Scientists were a divided lot over sending onboard Chandrayaan-I the Moon Impactor Probe which later produced excellent pictures of the earth's natural satellite.
The Moon Impactor Probe (MIP), which crashed onto the lunar surface on November 14, was included as one of the 11 payloads of Chandrayaan-I at the suggestion of the then President A.P.J. Abdul Kalam.
However, some scientists were doubtful about including the 28-kg MIP as a part of the payload and favoured carrying some other experiments, said senior scientist Narendra Bhandari, who has been involved with Chandrayaan-I since its inception.

Key scientists behind the Chandrayaan-1 mission are gathering in Bangalore on Thursday for the first time since the October 22 launch of India's maiden moon exploration to analyse preliminary data generated using payloads on board.
The day-long session at ISRO Satellite Centre in Bangalore assumes significance in view of some encouraging findings thrown up after India's historic moon odyssey.

C1XS X-ray camera
Permalink  
 

The C1XS X-ray camera, jointly developed by the UK's STFC Rutherford Appleton Laboratory and the Indian Space Research Organisation (ISRO), has successfully detected its first X-ray signature from the Moon. This is the first step in its mission to reveal the origin and evolution of our Moon by mapping its surface composition.
In orbit around the Moon on the Chandrayaan-1 spacecraft, C1XS detected the X-ray signal from a region near the Apollo landing sites on December 12th 2008 at 02:36 UT. The solar flare that caused the X-ray fluorescence was exceedingly weak, approximately 20 times smaller than the minimum C1XS was designed to detect.

"C1XS has exceeded expectations as to its sensitivity and has proven by its performance that it is the most sensitive X-ray spectrometer of its kind in history" - Ms. Shyama Narendranath, Instrument Operations Scientist at ISRO.

The X-ray camera collected 3 minutes of data from the Moon just as the flare started and the camera finished its observation. The signal reveals the X-ray fingerprint of a part of the lunar surface. As the mission continues, C1XS will build up a detailed picture of the ingredients that have gone into the Moon - our eighth continent.

 India's first unmanned moon mission, Chandrayaan-1, is providing scientists with the first look inside the moon's coldest and darkest craters, US space agency NASA has said.
The NASA radar on board the Chandrayaan-1 spacecraft has sent back its first images which 'show the floors of permanently-shadowed polar craters on the moon that aren't visible from Earth,' NASA said in a press release.

ISRO Chairman G. Madhavan Nair announced that the Chandrayaan has sent more than 40,000 images to the base station in the last two months.
These images are currently being analysed and will undoubtedly prove invaluable to the scientific community. The ISRO chief said that while there were many lunar missions in the past, none of them has been able to provide comprehensive data in the form of images so detailed.
The Chandrayaan has been able to capture images of the lunar surface and get a complete picture of the moon with resolutions of up to five meters. Compare this with earlier missions, which capture images with a 100-meter resolution and that too of a very limited area.
