About the Cover

Extrasolar planet, or exoplanet, is a planet outside the Solar System and that usually orbits a star other than the Sun. The first extra solar planets were discovered in 1992. More than 700 are known, and more than 2,300 await further confirmation. Extra solar planets are extremely difficult to detect directly. Most exoplanets can only be detected indirectly because bright light from the stars that they orbit drowns them out. One method is to look for tiny wobbles in stars' positions caused by their gravitational interactions with orbiting planets. The nearest known exoplanet is Alpha Centauri Bb. Most known exoplanet are giant planets believed to resemble Jupiter or Neptune, but this reflects a sampling bias, as massive planets are more easily observed (Ref: Brindha V, Exoplants are under structural development, Discovery Universe, 2013, 2(4), 3), (Image: sciencedaily.com).

ANALYSIS

Estimation of Thermodynamic Equilibrium Temperature of Chandrayaan-2 Rover Solar Panel during Long Lunar Nights


Raghu Meetei N, Sankaran M, Alok Kumar Shrivastava, Anil Agarwal, Ranganath S Ekkundi

Chandrayaan-2 is a continuity mission of its antecedent mission Chandrayaan-1. A rover is proposed in the mission to mainly carry out in-situ scientific experiments for better understanding of the resources for future exploration of the Moon surface.
