When NASA astronauts Sunita Williams and Butch Wilmore waved goodbye to their families as they set off to the International Space Station (ISS) in June, the pair expected to be back home just eight days later. Butch and his fellow NASA test pilot, Sunita, are staying onboard the ISS longer than expected following thruster failures and helium leaks on Boeing’s inaugural crew flight for its Starliner capsule. Butch and Sunita have said they are confident the capsule will return them home safely, but there’s no return date yet, which means the congregation’s worries have subsided for now since they are safe aboard the space station. Do you think space missions are like signing death certificate for yourself ?
