Chandrayaan-3: Updates on Lander Vikram and Rover Pragyan’s Lunar Activities

August 25, 2023

The Indian Space Research Organisation (ISRO) provided an update on the progress of its lunar mission, Chandrayaan-3. The Lander Vikram and Rover Pragyan are equipped with scientific payloads to conduct experiments on the lunar surface. ISRO announced that activities related to the mission are on schedule, with the Lander Module payloads ILSA, RAMBHA, and ChaSTE being activated. The Chandra’s Surface Thermo-Physical Experiment (CHASTE) on the lander will measure thermal properties near the polar region.

RAMBHA-LP, a Langmuir Probe, will measure surface plasma density, while a laser reflector aids in accurate positioning. ILSA, the Instrument for Lunar Seismic Activity, studies seismicity and lunar structure. SHAPE, or Spectro-polarimetry of HAbitable Planet Earth, analyzes atmospheric signatures in the near-infrared range.

What is the status update from ISRO regarding Chandrayaan-3’s Lander Vikram and Rover Pragyan?

ISRO reported that all activities related to Chandrayaan-3, including the Lander Module payloads ILSA, RAMBHA, and ChaSTE, are proceeding as planned. The rover’s mobility operations have commenced, and other operations are normal.

What is the significance of the Lander Module Payloads?

The Lander and Rover are equipped with scientific payloads to conduct experiments on the lunar surface. These payloads play a crucial role in gathering data about the lunar environment and conducting various scientific studies.

What are the experiments scheduled for the next two weeks on the lunar surface?

Over the next two weeks, experiments on both the Lander Vikram and Rover Pragyan will be carried out. The data collected from these experiments will cover the duration of the Moon’s Day (14 Earth days).

What is the purpose of the CHASTE payload on the Lander?

The Chandra’s Surface Thermo-Physical Experiment (CHASTE) payload aims to measure the thermal properties of the lunar surface near the polar region, providing insights into the moon’s temperature distribution.

How does the RAMBHA-LP contribute to the mission?

The RAMBHA-LP, a Langmuir Probe, measures surface plasma density, aiding in the understanding of the lunar environment’s plasma characteristics.

What is the role of the SHAPE payload?

The SHAPE payload, or Spectro-polarimetry of HAbitable Planet Earth, studies the atmosphere of Earth in the near-infrared wavelength range. It provides valuable information about Earth’s atmospheric properties.
