by The NASA and India have teamed up to start an earthly satellite that can pursue the slightest changes in land and ice.
The mission of $ 1.3 billion (980 million GBP) will help forecasters and first aiders to remain a step of flooding, landslide, volcanic eruptions and other disasters.
The satellite in orbit from India will examine the entire area of the earth several times. The two radar devices – one from the USA and the other from India – will operate day and night and look through clouds, rain and leaves to collect data movement exceptionally in detail.
Microwave signals, which from the dual radars that shine onto the earth, bounces off the satellite antenna reflector, which sits on the beach at the end of an umbrella like an umbrella.
Scientists will compare the incoming and outgoing signals if the spaceship goes over the same places twice every 12 days and changes as small as a fraction of a centimeter.
It is “a unique satellite satellite that will change the way we study our home planet and will better predict a natural disaster,” said Nicky Fox, head of the NASA science mission mission.
Ms. Fox led a small NASA delegation for the start to India.
“Congratulations India!” The Minister of Science and Technology, Jitendra Singh, posted as soon as the satellite surely reached the orbit, and added that the mission “benefits the entire world community”.
The deputy deputy administrator Casey, Casey Swails, part of the delegation that traveled to India, said it shows “The world really can do what our two nations can do.
It will take a week for the 30-foot boom of the satellite to open the drum-shaped reflector with 39 foot in diameter made of gold-plated wire network. The science operations should start by the end of October.

Under the most urgent measurements of the satellite: melting glaciers and polar ice sheets; Shifting groundwater consumption; Movement and stress of land areas that have landslides and earthquakes; and forest and wetland disorders that strengthen carbon dioxide and methane emissions.
The NASA wears $ 1.2 billion (£ 900 million) for the three-year mission at Sie delivered the low frequency radar and the reflector.
The 91 million dollar share of the Indian Space Research Organization (68 million pounds) comprises the high-frequency radar and main satellite structure as well as the start of a barrier island in the bay of Bengal. It is the greatest space cooperation between the two countries.
The satellite called Nisar short for the Radar Synthetic Aperture NASA-ISRO-WERD from an almost polar orbit of 464 miles. Dozens of straw observation missions that are already in operation by the United States and India will join.
