NASA and ISRO's joint NISAR satellite has captured its first detailed radar images of Earth's surface, demonstrating its capabilities in monitoring land and ice surfaces for applications like disaster response and environmental management, with full science operations expected later this year.

NASA's powerful radar system captured images of the stadium-sized asteroid 2008 OS7 as it passed by Earth at a safe distance of 1.8 million miles. The radar observations helped refine the asteroid's size to be around 500 to 650 feet across, smaller than initially estimated, and revealed its unusually slow rotation rate of one full rotation every 29.5 hours. The asteroid, designated as "potentially hazardous," won't come as close to Earth for another 200 years.
NASA's powerful radar system captured images of a stadium-sized asteroid, 2008 OS7, as it safely passed by Earth at a distance of 1.8 million miles. The radar observations revealed that the asteroid is smaller than initially estimated, measuring around 500 to 650 feet across, and rotates at an unusually slow rate. The Goldstone Solar System Radar's DSS-14 antenna, located in California's Mojave Desert, played a crucial role in these observations, providing valuable insights into near-Earth objects.
Radar images from the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR in Germany reveal damage on the European Remote Sensing (ERS-2) satellite during its final orbits before reentering Earth's atmosphere over the Pacific Ocean. The images show the buckling and bending of the satellite's solar array, which occurred earlier than expected and could have implications for understanding spacecraft behavior during reentry. The European Space Agency is assessing precise data regarding the reentry to improve forecasts of future natural reentries, as space agencies and companies are moving towards controlled reentries to minimize debris risk.
The European Space Agency's Aeolus satellite, which completed its mission to profile Earth's winds, has been captured in eerie radar images shortly before its fiery demise. The satellite, launched in 2018, spent nearly five years in orbit before being intentionally guided to safely burn up over an uninhabited area of Antarctica. The radar images, taken by the Fraunhofer Institute in Germany, provide a glimpse into the final moments of the mission and highlight the agency's efforts to mitigate space junk and ensure responsible operations.
