Chandrayyan 3 New Update Today
September 8, 2023
Chandrayaan-3 lander is imaged by the Dual-frequency Synthetic Aperture Radar (DFSAR) instrument onboard the Chandrayaan-2 Orbiter on September 6, 2023.
A SAR instrument transmits microwaves in a given frequency band and receives the same, scattered from the surface. Being a radar, it can image even without solar illumination. It can provide both the distance and physical characteristics of the target features. Hence, SAR is utilized for remote sensing of the Earth and other celestial bodies.
DFSAR is a key scientific instrument onboard Chandrayaan-2 Orbiter. It employs microwaves in L- and S-band bands. This state-of-the-art instrument is offering the best resolution polarimetric images currently on any planetary mission. The long radar wavelength enables DFSAR to explore lunar subsurface features down to a few metres. DFSAR has been beaming high-quality data by imaging the lunar surface, for the last 4 years, with main focus on the lunar polar science.
