The U.S. and India just sent a powerful new set of radar eyes into the sky.
The NISAR satellite, a joint mission of NASA and the Indian Space Research Organization (ISRO) lifted off today (July 30) from Satish Dhawan Space Centre in southeastern India, opening a new era of radar Earth observation.
NISAR is “the most sophisticated radar we’ve ever built,” Karen St. Germain, director of NASA’s Earth Science Division, said during a prelaunch briefing on Monday (July 28). “The science of NISAR will advance our understanding of the Earth system with cutting-edge technology capable of studying changes in land and ice — changes as small as a centimeter, in any weather and in both darkness and light.”
NISAR (short for NASA-ISRO Synthetic Aperture Radar) rose off the pad today at 8:10 a.m. EDT (1210 GMT; 5:40 p.m. India Standard Time) atop a GSLV Mk II, one of India’s brawniest rockets.
The three-stage, 170-foot-tall (52-meter-tall) launcher (whose name is short for Geosynchronous Satellite Launch Vehicle Mark II) did its job, deploying NISAR into a 463-mile-high (745-kilometer-high) orbit about 18.5 minutes after liftoff as planned.
“I am extremely happy to announce that GSLV Mk II vehicle has successfully and precisely injected the NASA ISRO Synthetic Aperture Radar satellite, NISR satellite, bringing 2300 kg into its intended orbit,” ISRO Chairman Dr V. Narayanan said to mission operators and guests in attendance at the launch after confirmation of payload separation. “Let me congratulate all the teams from ISRO and NASA JPL on this outstanding success.”
Following his remarks, NASA Deputy Associate Administrator Casey Swails said, “on behalf of NASA, I just I want to congratulate all of the teams. It is been just an incredible decade, culminating in this moment, from the technical collaborations, the cultural understandings, getting to know each other, building that team across continents, across time zones.”
“This Earth science mission is one of a kind, and really shows the world what our two nations can do. But more so than that, it really is a pathfinder for the relationship building that we see across our two nations,” she said.
Mission team members will spend the next 90 days or so checking out NISAR and its various systems, making sure everything is working well. Then, the…
