On October 22, 2008, the Indian Space Research Organization launched Chandrayaan-1, India's first planetary probe on the moon, ten years ago. In a few weeks, the successor to the mission – Chandrayaan-2 – should do the same after many unexpected delays in its launch date, a report in the time of India I said.
Chandrayaan-1 was India's first planetary mission on the moon and led various experiments, Indian and international, on lunar orbit. The probe collected many important data during its mission in orbit and studied the chemistry, geology and mineral composition of the Moon for nearly a year.
Conclusions of Chandrayaan-1
Among his many discoveries were direct evidence of water on the moon. Data from the Moon Mineralogy Mapper on Chandrayaan-1 were crucial in allowing the results to directly prove that the moon does have water on its surface. These deposits were found in the form of concentrated ice near the polar regions of the moon.
A second instrument on Chandrayaan-1, the synthetic mini-synthetic radar (Mini-SAR), has also detected ice-water deposits in craters located on the other side of the moon. This has been a blind spot for past lunar missions as well as for Earth observations because it is not well studied, but is also inaccessible to satellite signals for communication with mission controllers on Earth.
A third instrument, the Indian Moon Impact Impact (MIP) Chandrayaan-1, collected water signatures in the lunar exosphere.
Finally, the discovery that made headlines around the world was the first "direct evidence" of the presence of water in the lunar atmosphere just above the surface of the moon, collected by the planet. Altitudinal composition instrument of Chandra (CHACE) as the probe descended to the moon.
These discoveries were made largely because the probe instruments were designed to detect even traces of water – in the form of hydroxyl ions (OH), as opposed to the more well-known form of the water molecule (H2O). This indicated that solar radiation rapidly spilled water into hydrogen ions, which escaped from the atmosphere, and hydroxyl ions, which remained as traces of water. . .

the Chandrayaan Mission-2
The Chandrayaan-1 sequel is the 800 Rs crore "Chandrayaan-2"unmanned mission, scheduled for January 3, 2019. This comes close to ten years after ISRO's first mission on the moon, but wears a rover and a lander unlike the old one.
The 3,890-kg Chandrayaan-2, which will be launched aboard the geo-synchronous satellite launch vehicle (GSLV) Mk-3, will orbit around the moon and study its lunar conditions in order to collect data on its topography, mineralogy and its exosphere.
Chandrayaan-2, which weighs 3,890 kg, will be launched on board of Geosynchronous Satellite Launch Vehicle (GSLV) Mk-3.
It will orbit the moon and study its lunar conditions to collect data on its topography, mineralogy and exosphere.
"Chandrayaan-2 is scheduled for a window we are targeting from January 3 to February 16, 2019. This may happen at any time during this window, but we are aiming for the beginning of the window on January 3," Sivan said. addressing the media, according to to various reports.
When ISRO was asked about the rocket certification agency that would be carrying Indian astronauts, Sivan said ISRO would be the certification agency.
"You can say it's Chandrayaan-3 because the project has been completely reconfigured," Sivan told YOU. "If we had chosen the previous configuration, it would have been a disaster, they had not thought of so many problems, these are being fixed."
Sivan added that certification standards will be established with the help of the Directorate General of Civil Aviation; and that ISRO would like to benefit from the expertise of other countries in this regard.
This is the first time India has seen a rover land on the moon nearly 50 years after American astronaut Neil Armstrong stepped on the sinister lunar surface in 1969.
