A new NASA Earth science mission is currently being built and tested at the Jet Propulsion Laboratory. NISAR – or the NASA-ISRO Synthetic Aperture Radar – is an Earth-orbiting satellite that will collect critical data on how the planet is responding to climate change. But before it can begin its science, JPL engineers must design and build the unique technology that will set it apart, including the largest reflector antenna ever launched by NASA.In this live Q&A, we’ll talk with two NISAR mission team members and answer your questions about what it takes to monitor Earth’s vital signs.Guests: Wendy Edelstein, payload manager, NASA JPLRicha Sirohi, systems engineer, NASA JPL
NISAR’s large deployable antenna will be used in a unique operating mode known as SweepSAR to provide wide area coverage and fine spatial resolution at the same time. When it transmits microwaves, the radar’s signal feed is stationary, producing a narrow beam of microwave energy. But when it receives the returning signal echoes, the radar feed sweeps its beam across the antenna’s reflector, thus giving SweepSAR its name.

Today was all about NISAR!It’s nearly time for the scientific heart of this @NASAEarth satellite to head to southern India ahead of its planned 2024 launch, so of course, we had to send it off in true JPL style. https://go.nasa.gov/3Y8OQLd
NISAR, jointly built by @NASA and the Indian Space Research Organisation, will provide critical information on Earth’s crust, ice sheets, and ecosystems. Our collaboration with @isro exemplifies what’s possible when we tackle complex challenges together.
NASA has handed the NISAR spacecraft over to ISRO!It will be launched in early 2024 on a GSLV (Mk-2) rocket into a Sun Synchronous Orbit.
🛰 Media got a close-up view of part of NISAR before it ships to India! NISAR (NASA-ISRO Synthetic Aperture Radar) will observe Earth’s land & ice-covered surfaces.NASA is providing the L-band SAR and LSP has an advisory role in the 2024 launch! 🚀nisar.jpl.nasa.gov
Preparing GSLV Mk.III for 36 OneWeb satellites in middle of March. Commencing launch campaign immediately after today's launch for PSLV C55 for end of March on commercial mission. Using new facility. Preparing for landing demonstration of RLV in a few days time.For Gaganyan have abort and recovery mission today, another abort and recovery mission and trying for uncrewed mission before end of year.GSLV for NAVIC series satellite prior to NISAR, scheduled for end of this year. More PSLV missions as well.
Welcome, neighbor!The NISAR Earth-observing radar mission temporarily shares High-Bay 1 @NASAJPL with @EuropaClipper, as NISAR is prepared for encapsulation and shipment to @ISRO India. #PI_Daily
Touchdown in Bengaluru! @ISRO receives NISAR (@NASA-ISRO Synthetic Aperture Radar) on a @USAirforce C-17 from @NASAJPL in California, setting the stage for final integration of the Earth observation satellite, a true symbol of #USIndia civil space collaboration. #USIndiaTogether
NISAR is a big step closer to its 2024 launch. 🚀After years of construction, integration, and testing at JPL, the mission's science payload was recently packed up and shipped to @ISRO in India. Go inside the packing process with Scott Nowak, NISAR mechanical integration lead.
NISAR, or the [email protected] Synthetic Aperture Radar, will observe a wide range of Earth processes – from the flow rates of glaciers to the dynamics of earthquakes and volcanoes. Now in India, teams will finish assembly and prepare the spacecraft for launch:
