Chandrayaan-1 has reportedly encountered an unexplained rise in temperature.
According to ISRO (Indian Space Research Organisation) Chairman Madhavan Nair, the vessel has recorded a 10 degree increase in temperature, which is hot enough to affect its advanced instruments. Although moon surface temperatures often reach 100 degrees Celsius, a thermal blanket could theoretically be utilised to keep Chandrayaan-1 from overheating.
The otherwise uneventful mission has thus far been considered a success. Indeed, 9 scientific instruments on board the ship have been activated and are relaying data, including three-dimensional pictures of the moon's surface. However, the ISRO is still waiting to activate the High Energy X-ray Spectrometer (HEX) and the Sub keV Atom Reflecting Analyser (SARA). The HEX is slated to survey the moon's polar region for the presence of water, uranium and thorium, while the SARA will analyse the surface composition of the lunar body.
"These are high voltage systems. You have to wait for some time in orbit before they are switched on," Project Director M. Annadurai told the Hindu.
