KENNEDY SPACE CENTER, FLA. - The canister is lifted off the Mars Exploration Rover 1 (MER-B) in the gantry on Launch Complex 17-B, Cape Canaveral Air Force Station. The second of twin rovers being sent to Mars, it is equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow it to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans can't yet go. MER-B is scheduled to launch June 26 at one of two available times, 12:27:31 a.m. EDT or 1:08:45 a.m. EDT.

ISS010-E-05266 (28 October 2004) --- The Al Khufrah Oasis is featured in this image photographed by an Expedition 10 crewmember on the International Space Station (ISS). Green circles in the desert frequently indicate tracts of agriculture supported by center-pivot irrigation. The Al Khufrah Oasis in southeastern Libya (near the Egyptian border) is one of Libya’s largest agricultural projects, and is an easy-to-recognize landmark for orbiting crewmembers aboard the Station. The center-pivot irrigation system pumps water under pressure into a gantry or tubular arm from a central source. Anchored by a central pivot, the gantry slowly rotates over the area to be irrigated, thereby producing the circular patterns. Although the field diameters vary, these fields are approximately 0.6 mile (1 kilometer) in diameter. Darker colors indicate fields where such crops as wheat and alfalfa are grown. Lighter colors can indicate a variety of agricultural processes: fields that have been harvested recently; fields that are lying fallow; fields that have just been planted; or fields that have been taken out of production.

KENNEDY SPACE CENTER, FLA. -- READY FOR FLIGHT - On level three of gantry on pad 5, Project Mercury astronaut Virgil I. 'Gus' Grissom pauses briefly while a technician completes final adjustment in the Liberty Bell 7 spacecraft, which carried Grissom 118 miles into space on Friday, July 21, 1961. The craft's large trapezoidal observation window can be seen behind the pilot. The Pilot Observer Camera, which brought the astronaut's head and shoulders into view, was to reflect the lights on the flight events sequence panel through the 5-inch plexiglas parabolic mirror attached to Grissom's suit, to provide and accurately time record the pilot's voice communications, eye scan pattern and arm motions. The spacecraft sank on landing and has not been recovered. (NASA Photo)
