NASA to preview the advanced American radar mission before launch

NASA will organize a press conference at 12 p.m. to 12 p.m. Had on Monday July 21 to discuss the next Nisar mission (NASA-Isro synthetic opening radar).

The satellite observing the earth, a very first collaboration of its kind between NASA and the ISRO (Indian Space Research Organization), bears an advanced radar system which will help protect communities by offering a dynamic and three -dimensional vision of the earth in unprecedented details and by detecting the movement of terrestrial surfaces and ice until the century.

The Nisar mission will take off from the satisfaction of Sriharikota Dhawan Space Center on the south-eastern coast of India. The launch is targeted at the beginning of the end of July.

The NASA jet propulsion laboratory in South California will broadcast the live briefing on its X, Facebook and YouTube channels. Learn to look at the contents of NASA via a variety of platforms, including social media.

Participants in the press conference include:

• Nicky Fox, Associate Administrator, Directorate of the Scientific Mission, Headquarters of NASA
• Karen St. Germain, Director, Division of Earth Sciences, Headquarters of NASA
• Wendy Edelstein, deputy project manager, Nisar, Nasa JPL
• Paul Rosen, project scientist, Nisar, Nasa JPL

To ask questions by phone, media members must RSVP no later than two hours before the start of the event at: rexana.v.vizza@jpl.nasa.gov. NASA media accreditation policy is available online. Questions can be asked about social networks during the briefing using #asknisar.

With its two radar instruments – an S strip system provided by the ISRO and a L -shaped band system supplied by NASA – Nisar will use a technique known as the Synthetic opening radar (SAR) to scan almost all terrestrial and glacial surfaces of the planet twice every 12 days. The signal of each system is sensitive to the different sizes of characteristics on the surface of the earth, and everyone specializes in the extent of the different attributes, such as the humidity, surface roughness and movement.

These capacities will help scientists better understand the processes involved in natural risks and catastrophic events, such as earthquakes, volcanic eruptions, land sagging and landslides.

In addition, the penetration capacity of Nisar clouds will help urgent responses to communities during weather disasters such as hurricanes, storm waves and floods. The detailed maps that the mission will also create information on progressive and sudden changes occurring on the land and glacial surfaces of the earth.

Managed by Caltech for NASA, JPL leads the American component of the Nisar Project and provided the SAR in LA L. NASA JPL also provided the radar reflector antenna, the deployable boom, a high-speed communication subsystem for scientific data, GPS receiver, a semiconductor recorder and the subsystem of useful load data. The Goddard Space Flight Center from NASA in Greenbelt, Maryland, manages the nearby space network, which will receive the L -band data from Nisar.

Several ISRO centers have contributed to Nisar. The Space Applications Center provides the SAR of the mission’s g band. The Ur Rao satellite center has provided the space bus. The rocket is from Vikram Sarabhai Space Center, the launch services are via satisfaction Dhawan Space Center, and satellite mission operations are by the ISRO follow -up and command network. The national remote sensing center is responsible for receiving data in bands, the generation of operational products and distribution.
