NASA has successfully inflated a new experimental room at the International Space Station, two days after running into problems during the first attempt.

An astronaut spent seven hours yesterday opening and closing an air valve to expand the compartment.

Enough air finally seeped inside so the white pod could stretch to its full 13 feet in length and 10 and a half feet in diameter.

That's equivalent to a small bedroom.
