President Barack Obama and his family will attend NASA's planned launch of the space shuttle Endeavour on April 29, according to a White House official.

Obama and the first family are expected to watch Endeavour launch on its 25th and final mission before the shuttle - the youngest in NASA's fleet - is retired and sent to a California museum for public display. Endeavour is slated to blast off at 3:47 p.m. EDT (1947 GMT) on Friday, April 29 from NASA's Kennedy Space Center in Cape Canaveral, Fla. [ Photos: Shuttle Endeavour's Last Mission ]

"We are a White House agency - we always welcome a visit from the president," Kennedy Space Center spokesman Allard Beutel told

Obama last visited the Kennedy Space Center a year ago, in April 2010, to make a speech to employees about the new direction he was proposing for NASA. Obama cancelled NASA's moon-oriented Constellation program in favor of human missions to an asteroid and eventually Mars.

Next week's presidential visit will likely require extra security and arrangements during an already complex launch day at the seaside spaceport.

"When he came here last April, that took a lot of special arrangements," Beutel said. "It's the president. It's safe to say there always have to be special arrangements."

And Obama won't be the only high-profile attendee at the launch.

Wounded Congresswoman Gabrielle Giffords, D-Ariz., wife of Endeavour's commander Mark Kelly, also hopes to attend. Giffords is recovering at a Houston hospital after being shot in the head outside a Tucson grocery store in January.

However, Giffords' attendance will depend on her health and the advice of her doctors, Kelly and NASA officials have said. [ Video: Endeavour's Final Mission ]

Endeavour's STS-134 mission to the International Space Station will include four spacewalks to install spare parts and upgrade the orbiting laboratory. The shuttle will deliver a $2 billion astrophysics experiment, called the Alpha Magnetic Spectrometer, to the station.

The shuttle mission is scheduled to last 14 days, but NASA may decide to extend the flight by up to two extra days to fit in more work, mission managers have said.

The liftoff of Endeavour will be the second-to-last space shuttle launch before NASA retires its 30-year-old shuttle fleet . After the mission, Endeavour will be sent to the California Science Center for public display. Its sister orbiters, Discovery and Atlantis, will be retired at other museums.

Endeavour made its first flight in 1992.

The final space shuttle mission, the STS-135 flight of Atlantis, is targeted for June 28.
