Indigenously built RISAT-1 satellite launched on April 26 is capable of imaging even without sunlight and could penetrate through clouds, the Rajya Sabha was informed.

The Radar Imaging Satellite (RISAT-1) has cloud penetrating capability and also can image during day and night as well as all weather conditions, Minister of State in the Prime Minister's Office V Narayanasamy said during Question Hour on Thursday.

"This facilitates cloud penetration and imaging even without sunlight," he said adding for RISAT-1, imaging sessions around both 6 am and 6 pm are chosen.

The country's first indigenously designed microwave imaging satellite RISAT-1 was launched by Indian Space Research Organisation onboard India's Polar Satellite Launch Vehicle, PSLV C-19 from Sriharikota.

The perfect launch of the satellite catapulted India into a select band of countries having indigenous radar imaging technology.

Lauding India scientists for the launch, Narayanasamy said they are "second to no one in the world."

Come on man, this isn't adding anything new to the discussion. Of course it can see without Sunlight and through clouds- it has a synthetic aperture radar (SAR)!!!

Right Bro!
but no need to start new thread, with all due respect, its well known to all members that RISAT is one radar and works on radar frequency. Radar is making image or find objects on bases of electro magnetic waves return to it. no need light. I think perhaps either u r not science student or not learn the chapter on electro magnetic spectrum. plz kindly visit wiki on it. and that will throw more light on it.
