A trio of small NASA satellites flying around Earth may give new meaning to the phrase, "Can you hear me now?"

Three off-the-shelf smartphones were just launched to space as part of a NASA initiative to make powerful satellites cheaper.

The trio of PhoneSats aptly named Alexander, Graham and Bell were successfully launched into orbit Sunday (April 21) during the inaugural test flight of Orbital Sciences Corp's Antares rocket. The new private rocket launched from NASA's Wallops Flight Facility located on Wallops Island along Virginia's Eastern Shore.

NASA has confirmed that, all three of the coffee-cup-size PhoneSats are now in orbit and beaming back information.

"We expect them to stay up for about 2 weeks, but actually our mission with these is only going to last a few days," Andrew Petro, program executive for NASA's Small Spacecraft Technology Program told SPACE.com. "This is a test basically to see how they form." [See How PhoneSats Work (Video)]

The phones will basically function as the brain of the satellite. The three 3 pound (1.4 kilogram) cubes won't be used for communication purposes, Petro said. In fact, the phones cannot send or receive calls or text messages.

"The idea was to use that [the phone] as the brain for the satellite," Petro said. "What you end up with is a relatively inexpensive."

While most satellites can cost more than $1 million, the three PhoneSats cost $3,500 to $7,000 each.

Alexander and Graham both PhoneSat 1.0s are battery-powered and carry a Nexus One smartphone running Goggle's Android operating system on board. These kinds of PhoneSats were exposed to extreme conditions in 2011, according to NASA officials. The tiny satellite was tested during sub-orbital rocket flights, from high altitude balloons and on vibration and shock tables.

Bell is a more advanced kind of cubesat. The PhoneSat 2.0 built around a Nexus S smartphone running on Android comes equipped with solar panels and a two-way radio that allows engineers to control the satellite from the ground. Its solar panels could make longer missions using the satellite possible in the future, according to a statement from NASA.
