Monitoring Earth’s Vital Signs with NISAR: Meet the Mission Engineers (Live Q&A)

Quote
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 JPL
Richa 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.

Pictures of NISAR spacecraft in stowed position. Getting ready to be sent to environmental test facility for vibration tests, thermovac tests etc. at NASA JPL. It'll be shipped to India in early 2023.
