Launch of a ULA Atlas V 551 rocket from Cape Canaveral AFS today at 12:25:01 pm EDT.
(HOUSTON) -- Orbiting 240 miles high above earth, astronauts aboard the International Space Station use huge satellites in orbit to talk with controllers back at the Johnson Space Center in Houston.
On July 19, one astronaut aboard the orbiting complex called an iPhone 4 located in Mission Control to chat.
NASA astronaut Ronald Garan called an employee of the space center's iPhone to chat with a group of thirty visiting space tweeps -- those who use Twitter to chat and discuss space and science interests.
Garan, who is known as @Astro_Ron on the social network site, spoke for nearly two minutes to the group who threw questions at comments his way.
This aerospace reporter (@AbsolutSpaceGuy) was among those who spoke with the astronaut who commented at one point that it was past his bedtime.
This space tweep also recorded the conversation via his own iPhone 4, and is attached to this article.Atlanta Man Tweets for NASA: MyFoxATLANTA.com

ATLANTA - One local man is sharing his view of the historic mission - one tweet at a time.
Charles Atkeison of Atlanta saw the very first space shuttle launch as a boy. It's an experience he says inspired his love of space and science.
He now writes about the shuttle program professionally. But for the shuttle's final voyage Atkeison took on a different title - space "tweep."
NASA selected him from more than 5,000 applicants worldwide to tweet about what he sees and hears to his 881 followers.
Charles Atkeison's tweeting duties aren't over. He'll head to the Johnson Space Center and mission control to detail Atlantis' return to earth.
As the first booster arrived at noon, it received a heroes welcome as a small fire boat pumped water up and out in a salute to the first arriving craft, Liberty Star.
Standing on a pier next to the captain's wife and over forty on lookers, applause broke out and waves to the crew as the Liberty Star broke the quietness of the ocean's waves.
NASA boats Liberty Star and Freedom Star towed the twin boosters from behind and across the choppy waters of the Atlantic Ocean.
Waves and rain fall delayed retrieval efforts some 140 miles northeast of the Kennedy Space Center, off the coast of Jacksonville.
Each booster was then shifted to the side of the ship in which the booster had flown during launch. The Liberty Star carried the right hand booster on the ship's right or starboard side.
The 149-foot tall solid-fueled boosters produce a 700-foot golden flame, and carried Atlantis up to an altitude of 145,000 feet on July 8 before separating 125 seconds into the flight.
These were the final boosters to be towed in for years to come as the space shuttle program come to an end with this final flight.

If you are unable to attend the historic final space shuttle launch this week, north Georgia's Tellus Science Museum will host a special launch day event for the public.The first launch was that of Columbia in April 1981, and since then the space shuttle's huge payload bay allowed NASA to launch space telescopes and planetary probes, link up with Russia's Mir space station and construct the International Space Station.
The price of the launch viewing is free to members and is included in the normal admission price for visitors.
The museum's theater can support nearly 200 guests, and large television monitors outside the theater will also broadcast the final space shuttle launch.
Located northwest of Atlanta just off exit 293 and I-75 in Cartersville, this science museum is open seven days a week from 10 a.m. to 5 p.m. The center is closed on July 4th, Thanksgiving Day, Christmas Day and New Years Day.
With the arrival of summer, Tellus is a fun-filled, inexpensive option for those looking for a short day trip with the children.
Visit the Tellus web site for the latest on membership, guest pricing, directions and schedule information.

A pair of apple iPhone 4's will launch into earth orbit in July aboard the final space shuttle flight and will be used by astronauts during a series of experiments aboard the International Space Station. 
A NASA spacecraft is speeding out and away from our solar system and will make the first leap into interstellar space at any moment according to scientists at the Jet Propulsion Laboratory in California.
