  • Signal Acquired From NASA-ISRO’s NISAR Earth Satellite!

    Mission controllers for the NASA-ISRO NISAR (NASA-ISRO Synthetic Aperture Radar) mission have received full acquisition of signal from the spacecraft. The satellite will provide high-resolution data to help decision-makers, communities, and scientists monitor infrastructure and agricultural fields, refine understanding of natural hazards such as landslides and earthquakes, and help teams prepare for and respond to […]

  • NASA-ISRO’s NISAR Spacecraft Separates From Rocket’s Third Stage

    About 20 minutes after NISAR’s launch, members of the mission team celebrate third-stage separation in mission control at NASA’s Jet Propulsion Laboratory in Southern California.

    The NISAR (NASA-ISRO Synthetic Aperture Radar) spacecraft has separated from the third stage of ISRO’s Geosynchronous Satellite Launch Vehicle rocket and will soon spread its solar arrays to power itself. Technicians will now work to acquire signal from the spacecraft to verify its health. When it reaches its Sun-synchronous science orbit at an altitude of […]

  • Liftoff of NASA-ISRO’s NISAR!

    NISAR liftoff

    The NASA-ISRO NISAR (NASA-ISRO Synthetic Aperture Radar) spacecraft has lifted off from Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle rocket at 8:10 a.m. EDT (5:40 a.m. IST), Wednesday, July 30.

  • NASA-ISRO Earth Satellite NISAR Is ‘Go’ for Launch

    An elevated, wide photograph of a rocket on its launchpad. The white rocket, with booster rockets attached, stands vertically next to its large, multi-level service tower. The launch complex is surrounded by green vegetation, and in the background, a dramatic, cloudy sky is illuminated by the vibrant orange and yellow glow of a sunrise or sunset on the horizon.

    The NISAR (NASA-ISRO Synthetic Aperture Radar) mission has been given a “go” for launch by the Indian Space Research Organisation (ISRO). Mission and launch managers are counting down to the spacecraft’s launch from Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle rocket. Watch live coverage of the launch […]

  • NASA-ISRO’s NISAR Mission: By the Numbers

    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.

    The NISAR (NASA-ISRO Synthetic Aperture Radar) observatory marks not only the first hardware collaboration on an Earth mission between NASA and the Indian Space Research Organisation (ISRO), but also the first satellite to bring together L-band and S-band radar on one spacecraft. The combination makes for an exceptionally powerful synthetic aperture radar that will provide […]

  • NASA-ISRO’s NISAR Mission Set to Capture Earth’s Land, Ice in Detail

    An artist's rendering of the NISAR satellite in orbit around Earth. The satellite, which has a gold-colored body and two large, wing-like solar panels, is shown against the blackness of space. Below, the curve of the Earth is visible, with brownish landmasses and the planet's thin, glowing blue atmosphere.

    Following a successful launch on July 30, the NISAR satellite will orbit Earth for at least three years, using its sophisticated radar systems to scan nearly all the planet’s land and ice surfaces twice every 12 days. NASA and the Indian Space Research Organisation (ISRO) will jointly operate the spacecraft and gather science of high […]

  • Live Coverage for NASA ISRO’s NISAR Launch Begins

    A wide, low-angle shot of a rocket on a launch pad at dusk. The white rocket is positioned next to its mobile service tower and is surrounded by four tall, illuminated metal lattice towers. The sky behind is a deep blue with clouds, transitioning to a warm yellow and orange glow from the setting sun on the right horizon.

    Live launch coverage is underway from NASA’s Jet Propulsion Laboratory in Southern California of the NISAR (NASA-ISRO Synthetic Aperture Radar) mission. A collaboration between NASA and the Indian Space Research Organisation (ISRO), the Earth satellite is slated to launch at 8:10 a.m. EDT (5:40 p.m. IST), Wednesday, July 30, from Satish Dhawan Space Centre on […]

  • NASA-ISRO’s NISAR Earth Satellite Ready for Launch

    A low-angle, eye-level shot of the white NISAR satellite rocket on the launchpad. The rocket is tall and thin with "ISRO" and "INDIA" printed in red on its side, and the Indian flag is visible near the top. It stands against a cloudy, overcast sky, with lush green foliage out of focus in the foreground.

    The NISAR (NASA-ISRO Synthetic Aperture Radar) mission, a collaboration between NASA and the Indian Space Research Organisation (ISRO), is set to launch at 8:10 a.m. EDT (5:40 p.m. IST), Wednesday, July 30, from Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle rocket. About the length of a pickup […]

  • NASA, ISRO Earth Satellite Mission Set to Launch July 30

    The NISAR satellite is seen with two halves of a payload fairing.

    NASA and the Indian Space Research Organisation have set the launch readiness date for the NISAR (NASA-ISRO Synthetic Aperture Radar) mission for no earlier than Wednesday, July 30.  The Earth-observing satellite, which will be the first to carry L- and S-band radars, is set to lift off aboard an ISRO Geosynchronous Launch Vehicle from ISRO’s […]
