Chandrayaan-3

About Chandrayaan-3:

• Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the moon.
• The propulsion module will carry the lander and rover configuration till 100 km lunar orbit.
• It would launched by LVM3 from Satish Dhawan Space Centre in Sriharikota.
• Mission Life (Lander & Rover) - One Lunar day (~ 14 earth day).
• ISRO’s ambitious Chandrayaan-3 mission is aimed at demonstrating critical technologies to land the spacecraft on the south pole of the moon.
• Chandrayaan-3 spacecraft is a composite of three modules -- propulsion, lander and rover.
• Chandrayaan-3 mission carries scientific instruments to study the thermo-physical properties of the lunar regolith, lunar seismicity, lunar surface plasma environment and elemental composition in the vicinity of the landing site.
• The lander being launched to the Moon with Chandrayaan-3 will have Chandra's Surface Thermophysical Experiment to measure the thermal conductivity and temperature, along with the Instrument for Lunar Seismic Activity that will estimate the seismicity around the landing site, and a Langmuir Probe to calculate the plasma density and its variations.
• The rover, will have the Alpha Particle X-ray Spectrometer and the Laser-Induced Breakdown Spectroscopy instrument for deriving the elemental composition in the vicinity of the landing site.

Q1) What is the 1st spacecraft?

The Sputnik 1 spacecraft was the first artificial satellite successfully placed in orbit around the Earth and was launched from Baikonur Cosmodrome at Tyuratam (370 km southwest of the small town of Baikonur) in Kazakhstan, then part of the former Soviet Union.
