India’s Space Agency changed status of its Moon rover Pragyan to “sleep,” t with batteries charged and receiver on. It completed its two-week assignement conducting several experiments on the lunar south pole. The data it collected have been transmitted to the Earth. It will work again after the night time which is 14 days long, in late September. The spacecraft’s solar panel is oriented to receive the light at the next sunrise expected Sept. 22. Neither Vikram nor Pragyan carry radioisotope heater units often used on lunar missions to help keep spacecraft and their components warm to survive the deep cold of lunar night, with temperatures of minus 190 degrees Celsius.
The landing site is now named Shiva Shakti Point. Between the findings, in-situ measurements detected sulfur on the lunar surface. The rover’s laser-induced spectroscope instrument also detected aluminium, iron, calcium, chromium, titanium, manganese, oxygen and silicon. There was no word on the outcome of the rover searches for signs of frozen water on the lunar surface that could help future astronaut missions, as a potential source of drinking water or to make rocket fuel.One discovery was of seismic activity beneath the lunar surface, which appears to be of natural origin. Using the Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere the scientists at India’s space agency detected plasma particles at the lunar south pole.
