ISRO said on Saturday (02 September) that the Pragyan rover has completed its mission. It is now safely parked and set to sleep mode. Both payload APXS and LIBS onboard are now disabled. Data from these payloads are transmitted to Earth via the lander.
The battery is also fully charged. The rover is positioned in such a way that sunlight will fall on the solar panels when the next sunrise on the moon occurs on September 22, 2023. Its receiver is also kept on. It is expected to resume operations from September 22.
Chandrayaan-3 mission is only for 14 days. This is because the moon has 14 days of night and 14 days of light. The rover-lander can generate electricity in sunlight, but when night falls, the power generation process stops. Without power generation, the electronics will not be able to withstand the extreme cold and will malfunction.
The rover covered a distance of 100 meters
Earlier in the day, ISRO had said that the rover had covered a distance of 100 meters from the Shivashakti landing point. A graph of the distance between the lander and the rover was also shared. The Vikram lander landed on the moon on August 23. The rover took 10 days to cover this distance.
The six-wheeled rover weighs 26 kg. About 14 hours after landing on Thursday morning, ISRO confirmed the exit of the rover. The lander landed on the moon on August 23 at 6.4 pm. It moves at a speed of 1 cm per second.
Updates from Chandrayaan-3 till now
ILSA payload records earthquake on lunar surface: On August 31, ISRO said that the Lunar Seismic Activity (ILSA) payload mounted on Chandrayaan-3’s Vikram lander recorded a natural occurrence of an earthquake on the lunar surface. have done This earthquake occurred on August 26. ISRO said that the source of the earthquake is being investigated.
LIBS Payload Confirms Sulfur on Moon: A second observation sent on August 28 also revealed the presence of sulphur, aluminium, calcium, iron, chromium, titanium on the south pole of the moon. There are also manganese, silicon and oxygen on the surface, the search for hydrogen continues.
Rover Pragyan changed route after seeing a 4 meter crater: On August 27, a 4 meter diameter crater came in front of rover Pragyan. The crater was 3 meters ahead of the rover’s location. In such a situation, the command was given to the rover to change the route. Earlier too Pragyan had passed through a small pit about 100 mm deep.
Plasma found on surface, but less dense: Radioanatomy of the Lunar Hypersensitive Launosphere and Atmosphere-Langmuir Probe (RAMBHA-LP) Vikram has discovered plasma at the Moon’s south pole, although it is less dense.
Vikram lander’s first observation – surface temperature around 50 degrees: The ChaSTE payload mounted on Chandrayaan-3’s Vikram lander has sent the first observation related to the temperature of the Moon. According to ChaSTE i.e. Lunar Surface Thermophysical Experiment, there is a huge difference between the temperature on the surface of the moon and at different depths.
