Behind Goldin is astronaut Doug Wheelock; behind Jonathan is his mother, Penny. Jonathan suffers from erythropoietic protoporphyria, a rare condition that makes his body unable to withstand ultraviolet rays. The suit allows him to be outside during the day, which would otherwise be impossible. Jonathan's trip was funded by the Make-A-Wish Foundation and included a visit to Disney World. He and his family were among a dozen VIPs at KSC to view the launch of STS-99

Morgan; on Bush’s right is Joseph Rothenberg, associate administrator, Office of Space Flight; on the far right is Bill Readdy, manager at Johnson Space Center. Liftoff of Endeavour occurred at 10:06:01 p.m. EST. Endeavour and its five-member crew will deliver U.S. solar arrays to the International Space Station and be the first Shuttle crew to visit the Station’s first resident crew. The 11-day mission includes three spacewalks. This marks the 101st mission in Space Shuttle history and the 25th night launch. Endeavour is expected to land at KSC Dec. 11 at 6:19 p.m. EST

In the background, between them, are Jonathan's mother, Penny; his grandfather, John Janocka; and his sister, Jaimie.. At left is Mrs. Goldin. Jonathan suffers from erythropoietic protoporphyria, a rare condition that makes his body unable to withstand ultraviolet rays. The suit allows him to be outside during the day, which would otherwise be impossible. Jonathan's trip was funded by the Make-A-Wish Foundation and included a visit to Disney World. He and his family were among a dozen VIPs at KSC to view the launch of STS-99

CAPE CANAVERAL, Fla. -- At the Banana River Creek VIP viewing area at NASA's Kennedy Space Center in Florida, youngsters delight in meeting NASA astronaut Doug Wheelock before the launch of space shuttle Atlantis' STS-135 mission to the International Space Station. Atlantis with its crew of four; Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandy Magnus and Rex Walheim, lifted off at 11:29 a.m. EDT on July 8, 2011 to deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts for the International Space Station. Atlantis also will fly the Robotic Refueling Mission experiment that will investigate the potential for robotically refueling existing satellites in orbit. In addition, Atlantis will return with a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 is the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.

In addition, Atlantis will return with a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 is the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.
