NASA's first live tweet-up between the public and astronauts in space was cut short Wednesday by a false alarm on the International Space Station.

The station's two resident Twitterers - Nicole Stott and Jeff Williams - were mid-way through a live interview with a group of their Twitter followers gathered at NASA Headquarters in Washington, D.C., when they were interrupted by a loud beeping.

"Excuse us just a second," Williams said as he and Stott scrambled to check their consoles to investigate the source of the alarm. Soon after, the station passed out of communications range with ground stations, ending the live video link with the two astronauts.
