The Kessler syndrome (also called the Kessler effect, proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade—each collision generating space debris which increases the likelihood of further collisions. One implication is that the distribution of debris in orbit could render space exploration, and even the use of satellites, unfeasible for many generations.

GSLV Mk-3 is the latest version of GSLV. It can carry up to 4500 to 5000 kg satellites. Until now, India relied on EU’s Arianespace launch vehicle to send those INSAT-4 satellites. It will consist of 3 stages. 1st stage will have solid propellant, 2nd stage will have liquid propellant and 3rd stage will be cryogenic engine. GSLV MK-3 will make ISRO a competitive player in commercial launches of foreign satellites.

Thirty Meter Telescope will be the second largest of the existing and announced extremely large telescopes (ELT) which is under construction on Mauna Kea in Hawaii. The TMT will enable scientists to study fainter objects far away from earth providing information about early stages of the evolution of the universe. As a founding member of the important international scientific project, India will be a 10 percent partner in the project and 70 percent of its contributions will be "in kind".
