ISRO looks at ‘lucky’ Apr 20 for 1st radar imaging sat launch - Indian Express

After its launch was put off apparently due to ISRO row, India’s indigenously designed and developed all-weather satellite that has the unique capability of imaging during day and night may be launched on April 20, a “lucky” day for the space agency.

As preparations were underway for the blast-off from India’s spaceport of Sriharikota, ISRO is looking at ‘lucky April 20’.

RISAT-1, a Radar Imaging Satellite with the capability to take images of the earth during day and night as well as in cloudy conditions, is a first of its kind developed by India and has already reached the spaceport after being transported from here.

India had launched RISAT-2, which it bought from Israel for US$110 million, on April 20, 2009, and Resourcesat-2 mission took place on the same day last year. Both were successful ventures.

“April 20 is a lucky day for us,” an ISRO official told PTI here. After back-to-back failures of GSLV — one with Russian engine and the other with homegrown one — this statement did not come as a surprise.

RISAT-1, weighing around 1850 kg, is slated for launch by ISRO’s workhorse Polar Satellite Launch Vehicle (PSLV-C19 (XL)) into a 536 km orbit.The launch of the spacecraft, the country’s first microwave remote sensing satellite, was put off by at least a couple of months following the ISRO row, the fallout of the punitive action against four former space scientists for their role in the Antrix-Devas deal, that delayed the preparations.

RISAT-2 with all weather capability and ability to penetrate through clouds was realised in association with Israel Aerospace Industries. RISAT-2, primarily a spy satellite, is being used solely for Defence applications, keeping an eye on the borders and the country’s neighbourhood.
