NEW DELHI: The Indian Space Research Organisation (Isro) on Wednesday released images of Chandrayaan-3’s Vikran lander clicked by Pragyan rover on the lunar surface.
Isro releases images of Chandrayaan-3’s Vikram lander
The Indian Space Research Organisation (Isro) has unveiled images of Chandrayaan-3’s Vikram lander taken by the Pragyan rover on the lunar surface. The image was captured by the Navigation Camera onboard the rover. Isro stated that the NavCams for the Chandrayaan-3 Mission are developed by the Laboratory for Electro-Optics Systems (LEOS).
Chandrayaan-3 lander and rover continue to function on the lunar surface
The Chandrayaan-3 lander and rover have successfully completed half of their designed life on the lunar surface. They have been sending scientific data on a daily basis for the past week. Although the lander and rover are designed to last for one lunar day (14 Earth days), they have mechanisms in place to reactivate when the sun rises again after the long night. Both the Vikram lander and Pragyan rover are solar-powered and operate only during sunlit periods, when temperatures in the polar area are above 54°C.
Pragyan rover changes path to avoid crater
On August 27, the Pragyan rover encountered a 4-meter diameter crater located 3 meters ahead of its location, causing it to alter its path. It was previously reported that rover operations on the Moon are semi-autonomous, and ground stations need to transmit commands for its mobility. The rover’s onboard navigation camera data is downloaded to the ground for the generation of a digital elevation model (DEM). The ground and mechanisms teams then decide which path to take and send the command for the rover to follow. A similar operation was carried out on August 27 to ensure that the rover avoids the new crater.
- The Indian Space Research Organisation (Isro) has released images of Chandrayaan-3’s Vikram lander taken by the Pragyan rover on the lunar surface.
- The lander and rover have completed about half their designed life on the lunar surface and continue to send scientific data daily.
- The Pragyan rover changed its path to avoid a 4-meter diameter crater it encountered on August 27.
