SpaceX Rocket Sends A New Door To Space Station

More than 2 tons of supplies and gear are speeding toward the International Space Station, after a SpaceX Falcon rocket launched early Monday from Cape Canaveral, Fla. The cargo includes a new port that will standardize how spacecraft connect to the station.

The SpaceX Dragon craft will deliver its payload to the station Wednesday morning — but the mission has already been something of a success, as Brendan Byrne of member station WMFE reports.

"SpaceX was able to land the first stage of the booster at a landing site at Cape Canaveral a part of their plan for rocket re-usability," Byrne says. Adding a detail that area residents might already know, he adds, "A sonic boom from the reentry of the booster was heard across Central Florida."

From Melbourne, Fla., Rick Glasby of member station WFIT tells NPR's Newscast unit that the SpaceX craft's cargo includes biology experiments and hardware that is crucial to NASA's future plans.

"The hardware is a docking device, and it will enable NASA to send astronauts to the space station from American soil, instead of from Kazakhstan," Glasby says. "The docking adapter will permit crew capsules from Boeing and SpaceX to automatically rendezvous with the space station. Those flights are at least one to two years away."

This is the second attempt at sending the international docking adapter, or IDA, to the space station. The previous attempt ended in a dramatic explosion shortly after launch.

NASA says of the docking port, "The systems and targets for the IDA are much more sophisticated than previous docking systems and include lasers and sensors that allow the station and spacecraft to talk to each other digitally to share distance cues and enable automatic alignment and connection."
