Here's a short list of things ISRO will do for the first time en route to executing its Chandrayaan 2. #ISROMissions #ISROFirsts (another thread but not that long) 1/n
Over 5,000 people will witness the launch live from inside the premises of the Sriharikota spaceport thanks to a new 'Launch View Gallery' ISRO has erected for just this purpose. It's one of three components of a 'Space Theme Park' the org. has planned. #Chandrayaan2 2/n
The other two are a 'Rocket Garden' and a 'Space Museum'. Some deets:… #ISROFirsts #Chandrayaan2 3/n
The M1 mission, launching #Chandrayaan2, will see the first operational flight of the #GSLVMkIII rocket. It has thus far undertaken one suborbital test flight and two orbital test flights in Dec 2014, June 2017 and Nov 2018. 4/n
The last two missions launched the GSATs 19 and 29. On M1, the Mk III will fly with the C25 cryogenic upper stage. #ISROFirsts #Chandrayaan2 5/n
The #VikramLander on the #Chandrayaan2 mission will represent the first attempt of an ISRO instrument to soft-land on the Moon. This is as opposed to a crash-land, as the Moon Impact Probe on the #Chandrayaan1 mission did in November 2008. 6/n
It was among those instruments that detected the presence of water in the lunar south pole. Vikram will carry the ILSA seismometer, a thermal probe called ChaSTE, a Langmuir probe named RAMBHA and a retroreflector from NASA. #ISROFirsts #Chandrayaan2 7/n
The #PragyanRover on the #Chandrayaan2 mission will be the first mobile ISRO instrument on the surface of an extraterrestrial body. It weighs 27 kg and will travel a distance of 500 m (remember the difference between distance and displacement from school?). 8/n
It will carry two instruments: the Alpha Particle X-ray Spectrometer and the Laser-Induced Breakdown Spectroscope. #ISROFirsts #Chandrayaan2 9/n
Here's one not-so-first item: ISRO has said #Chandrayaan2 is a south-pole landing mission. However, Vikram's landing spot is near 70º S, where polar conditions begin around 80º S. So this isn't a polar region landing. 10/n
That said, Vikram will land closer to the lunar south pole than any mission before. #ISROFirsts #Chandrayaan2 11/n
