In today's episode of India Global, A NASA-SpaceX mission that aimed to clear the way for two stranded astronauts to get back to Earth has been postponed. The rocket aimed to fly four new crew members to the International Space Station (ISS) and pave the way for the return of Sunita Williams and Butch Wilmore. The NASA astronauts left Earth on 5 June 2024 for an eight-day mission and have been stuck at the ISS for over nine months, instead helping ongoing missions at the station with maintenance and experiments. SpaceX said the issue that forced the launch to scrub related to the hydraulics on one of the clamp arms, which engineers were trying to fix. NDTV's Gaurie Dwivedi speaks with Former NASA scientist and Global Space Ambassador Dr Ravi Margasahayam to discuss this and more.
