    NASA-ISRO Mission Aces Checkouts, on Track to Start Delivering Science

    An artist's rendering of the NISAR satellite in orbit above Earth. The spacecraft is positioned on the left against the blackness of space, with its large, mesh-like radar antenna unfurled on a long boom. Below and to the right, the curve of the Earth reveals a vast, reddish-orange desert landscape under a thin blue atmosphere.

    After launching July 30, the NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing radar satellite mission, a joint effort between NASA and the Indian Space Research Organisation (ISRO), is on schedule to start science operations this fall. Following the deployment of its 39-foot (12-meter) radar antenna reflector on Aug. 15, engineers powered on the satellite’s L-band and […]

    Giant Radar Antenna Reflector on NASA-ISRO Satellite in Full ‘Bloom’

    An artist's rendering of the NISAR satellite in orbit with its large reflector antenna fully deployed. A long boom connects the main satellite body, which has solar panels, to the massive, circular, fine-mesh antenna. The satellite is pictured high above the curved horizon of the Earth, which shows mountainous terrain and has a pink and purple atmospheric glow.

    Seventeen days after NISAR’s launch from southeastern India, an essential piece of science hardware has unfurled in orbit. Spanning 39 feet (12 meters), the drum-shaped antenna reflector on the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission from NASA and the Indian Space Research Organisation (ISRO) successfully unfurled in low Earth orbit. The reflector had been […]
