NASA to Preview Superior US-India Radar Mission Forward of Launch

NASA will host a information convention at 12 p.m. EDT Monday, July 21, to debate the upcoming NISAR (NASA-ISRO Artificial Aperture Radar) mission.

The Earth-observing satellite tv for pc, a first-of-its-kind collaboration between NASA and ISRO (Indian Area Analysis Organisation), carries a complicated radar system that may assist shield communities by offering a dynamic, three-dimensional view of Earth in unprecedented element and detecting the motion of land and ice surfaces right down to the centimeter.

The NISAR mission will elevate off from ISRO’s Satish Dhawan Area Centre in Sriharikota, on India’s southeastern coast. Launch is focused for no sooner than late July.

NASA’s Jet Propulsion Laboratory in Southern California will stream the briefing reside on its X, Fb, and YouTube channels. Learn to watch NASA content material by way of quite a lot of platforms, together with social media.

Individuals within the information convention embody:

• Nicky Fox, affiliate administrator, Science Mission Directorate, NASA Headquarters
• Karen St. Germain, director, Earth Science Division, NASA Headquarters
• Wendy Edelstein, deputy challenge supervisor, NISAR, NASA JPL
• Paul Rosen, challenge scientist, NISAR, NASA JPL

To ask questions by cellphone, members of the media should RSVP no later than two hours earlier than the beginning of the occasion to: rexana.v.vizza@jpl.nasa.gov. NASA’s media accreditation coverage is on the market on-line. Questions might be requested on social media through the briefing utilizing #AskNISAR.

With its two radar devices — an S-band system offered by ISRO and an L-band system offered by NASA — NISAR will use a method generally known as artificial aperture radar (SAR) to scan almost all of the planet’s land and ice surfaces twice each 12 days. Every system’s sign is delicate to completely different sizes of options on Earth’s floor, and every focuses on measuring completely different attributes, resembling moisture content material, floor roughness, and movement.

These capabilities will assist scientists higher perceive processes concerned in pure hazards and catastrophic occasions, resembling earthquakes, volcanic eruptions, land subsidence, and landslides.

Moreover, NISAR’s cloud penetrating capacity will help pressing responses to communities throughout climate disasters resembling hurricanes, storm surge, and flooding. The detailed maps the mission creates additionally will present data on each gradual and sudden modifications occurring on Earth’s land and ice surfaces.

Managed by Caltech for NASA, JPL leads the U.S. element of the NISAR challenge and offered the L-band SAR. NASA JPL additionally offered the radar reflector antenna, the deployable increase, a high-rate communication subsystem for science knowledge, GPS receivers, a solid-state recorder, and payload knowledge subsystem. NASA’s Goddard Area Flight Middle in Greenbelt, Maryland, manages the Close to Area Community, which is able to obtain NISAR’s L-band knowledge.

A number of ISRO facilities have contributed to NISAR. The Area Functions Centre is offering the mission’s S-band SAR. The U R Rao Satellite tv for pc Centre offered the spacecraft bus. The rocket is from Vikram Sarabhai Area Centre, launch providers are by way of Satish Dhawan Area Centre, and satellite tv for pc mission operations are by the ISRO Telemetry Monitoring and Command Community. The Nationwide Distant Sensing Centre is answerable for S-band knowledge reception, operational merchandise technology, and dissemination.
