Agency Plans To Maximize Station Use Before Retirement

NASA has announced plans to continue exchanging International Space Station crews about every six months, after considering longer stays. The next commercial crew mission, SpaceX’s Crew-13, will launch in mid-September, bringing NASA astronauts and a Canadian Space Agency astronaut to the station. NASA’s decision to maintain the six-month cadence may be part of efforts to maximize use of the ISS before its scheduled retirement at the end of the decade, according to NASA ISS operations and integration manager Bill Spetch. This development was first reported by SpaceNews.
