In this next episode of our series on deep tech in India Arindrajit Chowdhury and Tausif Shaikh, co-founders of Inspecity Space Laboratories, talk about how they dream of cities in space. Their contribution is their two-year old venture, which is preparing to soon launch a small CubeSat propulsion system the size of a small tiffin box. It will take them one small step forward in developing an ecosystem of in-space life extension of satellites, involving repairs, navigations and eventually controlled de-orbiting manoeuvres
