India's achievement in areas of nuclear science and space research
Answers
India sent it's first lunar probe Chandrayaan 1 in october 2008 making India the fouth country to put it's flag on the Moon. The estimated cost of the project was $ 60 mn.
It operated untill August 2009. Some failure occured in the probe and it stopped sending signals, but even after sudden closure of the mission it was found that probe had already completed it's 95% planned work. On 24 September 2009 Science journal reported that the Moon Mineralogy Mapper (M3) on Chandrayaan-1 had detected water ice on the Moon.

These images show a very young lunar crater on the side of the Moon that faces away from Earth, as viewed by Chandrayaan-1's NASA Moon Mineralogy Mapper equipment.
2. Mars Orbiter Mission (MOM) :
Also called Mangalyaan, sent to orbit the Mars on 5 November 2013. It got inserted in the orbit on 24 September 2014. It will help in getting knowledge about mars.
India became the first nation to send a probe successfully to the mars in it's first attempt.
Cost of this project is said to be less than that of the Oscar winning movie Gravity.
3. 104 satellites in one go:
The Indian Space Research Organization set a record by launching CARTOSAT2 satellite and 103 others in one flight.
It included 2 Indian nano satellites INS 1A and INS 2A.
Of the 101 co-passenger satellites, 96 of these belong to USA, and one each are from ISRO’s international customers Israel, Kazakhstan, Netherlands, Switzerland and United Arab Emirates.
The entire launch carried a satellite mass of about 1,378 kg.
And latest, in which I'm very much interested,
4. LIGO India:
LIGO INDIA is a collaboration between the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory (operated by Caltech and MIT) and three Institutes in India – the Raja Ramanna Center for Advanced Technology (Indore), the Institute for Plasma Research (Ahmedabad), and the Inter-University Centre for Astronomy and Astrophysics (Pune). These three institutions bring the complementary skills and resources needed the success of the project.
The scientific goals of the project are in the area of astronomy and fundamental physics. Gravitational waves are predicted as an essential element of Einstein’s Theory of General Relativity. The strongest sources of gravitational waves are among the enigmatic objects in our universe: black holes, neutron stars, supernovae, even the Big Bang. Extracting the information carried by the waves to address questions in both physics and astronomy depends on our ability to identify where the individual sources are on the sky. This requires a network of detectors spread widely over the Earth. LIGO operates two sites in the United States and collaborates with a similar detector in Italy (Virgo). Together they can triangulate sources over part of the sky. LIGO-India will enable scientists to locate sources over the entire sky. The dramatic improvement with LIGO-India is the key scientific motivation for this project.
That's all from my side. If any corrections, then let me know. And share your knowledge too.
Thank you.
