India and the US are cooperating big time in space. It may come as a surprise but NASA's Ingenuity Mars Helicopter, flown as part of the Mars 2020 mission alongside the Perseverance Rover, was made by an Indian citizen Dr Bob Balaram working at the Jet Propulsion Laboratory. Early next year an Indo-US jointly made earth imaging satellite named NISAR will be flown from Sriharikota. NDTV's Pallava Bagla had a rare look at these missions on a visit to California.
