@isro Explaining why landing is planned at dawn, Isro chief S Somanath had said in Jul: “...We want landing when Sun rises on Moon so we get 14-15 [Earth] days to work… ” 3/n
@isro Once Sun sets, there’ll be no power for lander & rover to function & all equipment will stop working. However, Isro tests have shown possibilities of battery getting recharged upon the next Sun rise. If that happens, we could get another 14 days or maybe even more. 5/n
@isro In Queue To Reach #Moon: While #Vikram is just days away from landing, Russia’s #Luna25, which was scheduled to pip #Chandrayaan3 in reaching the polar region of Moon failed. 9/n
@isro But #Chandrayaan3 & #Luna25 aren’t the only lunar missions planned this decade. They are only the first among at least 10 other lunar missions planned between now and 2025, with the US, Israel, China and Japan — including a joint mission with India — all going to Moon. 10/n
@isro The US will launch CLPS, Trailblazer, VIPER & Artemis-II, China has multiple missions under CLEP, Israel is planning Beresheet-2 and Japan will launch Hakuto-II & III and SLIM independently, and Lupex (Lunar Polar Exploration) jointly with India. 11/n
@isro These missions are part of a renewed interest globally to return to Moon and efforts for a more sustained presence. Aside from these, the lunar orbit is already crowded albeit low compared to Earth orbits, posing a challenge of collisions for all lunar missions. n/n
