The US and India have just sent a powerful new radar eye set to the sky.
The NISAR satellite, the NASA Mission and the Indian Space Research (ISRO), today (July 30) from the Satish Dhawan Space Center in southeast India, opened a new Era of Radar Earth.
Nisar is “the most modern radar we have ever created,” said Karen St. Germain, said Monday (July 28) during the pre -report. “Nisar’s science will increase our understanding of the Earth system with the most advanced technologies that can explore the changes in the Earth and Ice, such as small as a centimeter, in any weather and in the dark and light.”

Nisar (a short nasa-corpse synthetic aperture radar) rose from the pallet today at 8:10. EDT (1210 GMT; 17:40 Indian standard time) on GSLV MK II, one of the Indian defamation missiles.
The three -tier, 170 -foot (52 -meter -high) launches (whose name is brief to the geosynchronous satellite launch vehicle Mark II) did its job, about 18.5 minutes after the height of 463 miles is planned.
“I am extremely pleased to announce that the GSLV MK II vehicle has successfully and accurately injected NASA Synthetic diaphragm radar satellite NISR satellite, bringing 2300 kg to its intended orbit,” Dr. “Let me congratulate all ISRO and NASA JPL teams for this great success.”
Based on her comments, Casey Swails, Deputy Associate Administrator, said: “NASA’s name I just want to congratulate all teams. It was just an incredible decade, which is currently the end of technical cooperation, cultural understanding,
“This land science mission is peculiar and actually demonstrates to the world what our two nations can do. But more than it is a relationship finder we see through our two nations,” she said.
Missing team members will spend about 90 days to check Nisar and its various systems, making sure everything works well. The satellite will then begin its ambitious mission of land observation.
NISAR will check the surface of our planet, using a synthetic aperture radar (SAR), which can be associated with clouds and acting in all lighting conditions. There are two SAR instruments in the spacecraft, one in NASA and the other is by isro. Their radar signals will be directed to the Earth 39 -foot wide (12 meters wide), a reflector of an antenna built by NASA, which began in a folded configuration. The golden reflector also catches back waves with a wealth of interesting information about the surface that bounces them back.
“We will see Nisar’s natural hazards such as earthquakes, landslides and volcanoes,” said St. Germain.
“We will see a land downturn and mountain glaciers and ice sheets covering both Greenland and Antarctica, movement, movement, deformation and melting, and of course we will see fires,” she added. “We will also see changes in land -induced land, such as farm and ranch production, water use for municipal drink and farm humidification and infrastructure, land development, homes, commercial buildings, railways, highways and bridges.”

Nisar orbit will take it through both poles, so the satellite will look good at the ice sheets. NISAR will scan almost the entire ice and land on the planet every six days, which will do this for at least five years. (NASA SAR instrument has a three -year initial mission life, but his ISRO colleague should run for five)
According to India Today, all Nisar mission spending is about $ 1.5 billion. NASA accounts for about 80% of the account, reported in the store.
Nisar’s roots go all the way until 2007; The mission was a response to the priorities of land observation in that year, presented by a “decadeal investigation” published by the US National Academy of Sciences. Nisar’s partnership was officially established in 2014. September 30, when the then NASA administrator Charles Bolden and the then President of Isras K. Radhakrishnan signed the documents.
