Indian Air Force Group Captain Shubhanshu Shukla said sustainable practices adopted in space offer lessons for North Eastern states like Meghalaya, expanding renewable energy in remote areas. Speaking at the 23rd National Space Science Symposium hosted by North East Space Application Centre (NESAC) at Umiam near here on Thursday, Shukla, the second Indian astronaut, stressed that life aboard the International Space Station depends almost entirely on solar power. "Astronauts reuse critical resources in an extremely limited environment. That discipline shows sustainable practices are attainable and practical for us as well," Shukla, the first Indian to visit the International Space Station in 2025, told students and researchers during an interaction session on Thursday. He commended Meghalaya's efforts to promote clean energy in rural and remote regions where conventional electricity supply remains a challenge.
