NASA’s Nasser Earth Satellite (the image of concept is shown) will carry a modern double band radar system to make the land and ice map in 3D. NASA Pir will host a news conference at the EDT at 12pm on July 21 to predict the mission and its science goals. Nasser Satellite is the first kind of cooperation between NASA and India’s ISRO and is designed to provide unprecedented 3D ideas of the land and detect the movement of up to cm. The launch has been targeted before the end of July, in which the briefing was issued directly online by NASA’s Jet Propulsion Laboratory from the Satish Dhawan Space Center in Siriharikota.
Mission Review
According to NASA, Nasser (NASA ISRO artificial aperture radar) is an angry satellite from the land that is jointly developed by NASA and India’s ISRO. For Mission Hardware, NASA’s Jet Propulsion Laboratory (JPL) provided L -Band radar and key electronics, while ISRO participated in the Sbind radar, spacecraft bus and launch vehicle. The satellite takes these twin radar systems to systematically make the planet’s land and ice levels systematically map. Using artificial aperture radar (SAR), it will scan almost all the land and ice about twice a day every 12 days. Nasser, under the JPL, is set to remove the Satish Dhawan Space Center in Sarayarkota before the end of July 2025. After deployment, it will regularly visit the Earth, and will present a high resolution radar image for scientists around the world.
Modern Radar Technology and Applications
Nasser will measure the earth’s surface dynamics according to the cm. Its double band radar design is key: L band radar (25 cm wavelengths) can penetrate into plants and soils, while low Siband (10 cm) is more sensitive to fine surface details. The return of each frequency shows different features – moisture level, surface roughness and movement. Jointly, they can detect small elevation changes in wider areas, which can help scientists monitor natural risks and climate change.
For example, the Nasser data will map a map of land deformation before and after the volcano erupted. And since the radar can see through the clouds, it will be invaluable for disaster reaction, map of floods and storm damage even during hurricanes or heavy rains.
