The spacecraft will take two months to get to the moon, first going into orbit 60 miles above the lunar surface before deploying the Vikram lander in September.

The launch will happen at 2.51 am from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

Since the 1980s, ISRO was dependent on foreign launchers to put satellites that weigh more than 2,300 kgs into space but that changed with the launch of GSLV Mk-III in 2017.

Chandrayaan-2, the most complex mission yet for the Indian Space Research Organisation (ISRO), will be launched on July 15 at 2:51 hours.

The Indian Space Research Organization plans to launch a spacecraft using homegrown technology on Monday at 2:51 am, and it is scheduled to touch down on the moon September 6 or 7.

With a total mission mass of 3.8 tonnes, the entire project is set to cost Rs 978 crore - Rs 603 crore for the spacecraft and Rs 375 crore for the GSLV Mk-III.

GSLV Mk III is now capable of placing a 4,000 kg satellite in the Geosynchronous Transfer Orbit, which is at a height of about 42,000 kilometres above the Earth's surface.

The spacecraft will have a lunar orbiter, lander and a rover. The launch will take up an orbiter, a lander, and a rover, dubbed Pragyan, all created to study the moon's little explored south pole. If Chandrayaan-2 is able to find ice in this part of the moon, it will be easier for humans to stay here.

To do this, the rover will carry a lot of state-of-the-art instrumentation like cameras, an alpha proton X-ray spectrometer and a laser-induced ablation spectroscopy experiment.

It is also the first such Indian mission with indigenous technology. "That area is the South Pole of the moon", said D.B. Pathak, principal of the Kendriya Vidyalaya, IISC.

ISRO is following the same launch strategy followed for Chandrayaan-1.

The range of Chandrayaan 2 encompassing the moon will be approximately 100X100 km orbit through a set of movements. Operators will then progressively raise its orbit until it enters the influence of the moon's gravity. In that nearly year-long successful mission, an impact probe struck the moon's south pole in a controlled manner. The Lander will soft-land on the lunar surface and unload the Rover to study and take measurements from the surface.

Website Planetary News says that "One of the most compelling results from Chandrayaan-1 was the detection of water (OH) on the Moon by both the Moon Mineralogy Mapper (M3), a NASA provided instrument, and ISRO's Moon Impact Probe (MIP)".

How will the mission study the moon?

This is a science that ISRO has only tested in laboratory conditions, and this is why chairman K. Sivan calls it the most "terrifying" 15 minutes of the mission.
