Chandrayaan-2 by ISRO| Upcoming mission & history of chandrayaan

HIGHLIGHTS

1. ISRO have planned to launch Chandrayaan-2 in early 2019.
2. It will be the successor of Chandrayaan-1 which was launched on Oct. 22,2008.
3. It will help India in achieving it's goals of becoming space heavyweights.

HISTORY

1. Chandrayaan-1 was India's first mission to moon, it operated for almost a year between October 2008 to September 2009.
2. It was launched on October 22 2008 from Satish Dhawan Space Centre Sriharikota,India.
3. A/C to NASA it reached moon on Nov. 8 2008.
4. Initially it was given a task to perform the process of mapping the orbit at 100 Km altitude.
5. On May 2009 the altitude was raised to 200 Km, agency lost communication with it on Aug. 2009.

GOALS OF CHANDRAYAAN-1

1. It included Terrain Mapping Camera (TMC) to obtain high resolution images of the surface of Moon.

2. It included Hyper Spectral Imager to obtain mineralogical mapping or simply we can say that to study size,shape,distribution of geological materials on the surface.

3. It also included Lunar Laser Ranging Instrument to study the topography of the moon's surface.

4. A High Energy X Ray Spectrometer, Moon Impact Probe to examine the radioactive elements & to demonstrate the technologies required to reach a certain position on the surface of moon& technologies for future safe landing of missions on the surface.

MAJOR IMPACT

1. NASA on Sep. 2009 announced that data collected by Chandrayaan-1 has helped them to prove the evidence of water on earth.
2. Earlier there were evidences of presence of water on the surface of moon like CASSINI spacecraft spotted it in the year 1999 when it passed moon on it's journey to Saturn.

3. NASA'S LCROSS (Lunar Crater Observation & Sensing Satellite) found more evidences of water on the south pole which was confirmed on Nov. 2009.

ALL ABOUT CHANDRAYAAN-2

1.  A/C to ISRO India's second mission to moon will comprise of  orbiter,lander & a rover.
2. On reaching 100 Km lunar orbit Lander housing the rover will separate from the orbiter, then lander will softly land on a specified location & after that rover will also be deployed from it.
3. Chandrayaan-2 will carry a six wheeled rover which will move around the surface at a autonomous mode as decided by the ground commands.
4. Rover will try to observe the lunar surface for study of the lunar soil.
5. Whole Chandrayaan-2 will weigh around 3290 kg and would orbit around the moon and perform the objectives of remote sensing the moon.
6. The payloads will collect scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice.
7. NOTE:- ISRO has decided to delay the launching of Chandrayaan-2 from April to July this year due to failed landing of Israeli mission known as Beresheet.
