CAPE CANAVERAL, Fla. (AP) Stuck-in-space astronauts Butch Wilmore and Suni Williams said Friday its been tough dealing with their Boeing ride leaving without them and the prospect of spending several extra months in orbit.

It was their first public comments since last weeks return of the Boeing Starliner capsule that took them to the International Space Station in June. They remained behind after NASA determined the problem-plagued capsule posed too much risk for them to ride back in. Their eight-day mission is now expected to last more than eight months.

It was trying at times. There were some tough times all the way through, Wilmore said from 260 miles (420 kilometers) up. As spacecraft pilots, you dont want to see it go off without you, but thats where we wound up.

While they never expected to be up there nearly a year, as Starliners first test pilots, they knew there could be problems that might delay their return. Thats how things go in this business, Williams said.

Wilmore and Williams are now full-fledged station crew members, chipping in on routine maintenance and experiments. Williams will take over command of the space station in a few more weeks, Wilmore told reporters during a news conference only their second since blasting off from Florida on June 5.

The duo, along with seven others on board, welcomed a Soyuz spacecraft carrying two Russians and an American earlier this week, temporarily raising the station population to 12, a near record. And two more astronauts will fly up on SpaceX later this month; two capsule seats will be left empty for Wilmore and Williams for the return leg.

The transition to station life was not that hard since both had previous stints there, said Williams, who logged two long space station stays years ago.

This is my happy place. I love being up here in space, she said.
