CAPE CANAVERAL, Fla. -- Technicians in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, prepare crawler-transporter 2, or CT-2, for removal of the roller bearing assemblies. After inspections, new assemblies will be installed. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades to CT-2 so that it can carry NASA’s Space Launch System heavy-lift rocket and new Orion spacecraft to the launch pad. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.

CAPE CANAVERAL, Fla. -- Kennedy Space Center Employees and guests placed wreaths and flowers at the Space Mirror Memorial at the spaceport's Visitor Complex during NASA's Day of Remembrance. The annual event took place on the 10th anniversary of the loss of the space shuttle Columbia and its crew and was hosted by the Astronauts Memorial Foundation. The ceremony also honored the astronauts of Apollo 1, who perished in 1967, and the shuttle Challenger, lost in 1986, as well as other astronauts who lost their lives while furthering the cause of exploration and discovery. Dedicated in 1991, the names of fallen astronauts are emblazoned the monument's 4.5-foot-high-by-50-foot-wide polished black granite surface which reflects the sky and has been designated by Congress as a National Memorial.

CAPE CANAVERAL, Fla. – – In high bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a worker examines the Ares I-X crew module simulator as it is lowered onto a stand. Ares I-X is the test flight for the Ares I. The I-X flight will provide NASA an early opportunity to test and prove hardware, facilities and ground operations associated with Ares I. The launch of the 327-foot-tall, full-scale Ares I-X, targeted for July 2009, will be the first in a series of unpiloted rocket launches from Kennedy. When fully developed, the 16-foot diameter crew module will furnish living space and reentry protection for the astronauts. Photo credit: NASA_Tim Jacobs
