NASA Open To Extending ISS Beyond 2030

Jeff Foust reports via SpaceNews: A NASA official opened the door to keeping the International Space Station in operation beyond 2030 if commercial space stations are not yet ready to take over by the end of the decade. Speaking at the Beyond Earth Symposium here Nov. 2, Ken Bowersox, NASA associate administrator for space operations, said it was "not mandatory" to retire the ISS as currently planned at the end of the decade depending on the progress companies are making on commercial stations. "The timeline is flexible," he said of that transition from the ISS to commercial stations. "It's not mandatory that we stop flying the ISS in 2030. But, it is our full intention to switch to new platforms when they're available." [...] Bowersox acknowledged that schedule depends on the readiness of those commercial stations. "When it happens is going to depend a lot the maturity of the market," he said, which includes both the status of commercial stations and non-NASA customers for them. He made it clear that NASA does not expect to be the only customer for commercial stations. NASA's current requirements for those stations anticipate having two astronauts at a time on them, less than the ISS. "We looked at what we thought would be reasonable and what would actually give us a cost savings," he said of that requirement. "My biggest concern is if we get too far ahead of where the market and NASA has to carry the full cost of the platforms for longer, and we transition too quickly," he said. That could force NASA to move money from current ISS utilization to support those stations. "If we have a badly managed transition, we could find ourselves getting weak in those areas."
