These measurements should reveal the size, matter content, age, geometry and fate of the universe. They will also reveal the primordial structure that grew to form galaxies and will test ideas about the origins of these primordial structures. The MAP instrument will be continuously shaded from the Sun, Earth, and Moon by the spacecraft. It is a product of Goddard Space Flight Center in partnership with Princeton University

KENNEDY SPACE CENTER, FLA. - A worker from Ball Aerospace and Technologies Corp. examines the High Resolution Imaging Science Experiment (HiRISE) camera that is launching on the Mars Reconnaissance Orbiter Aug. 10. HiRISE is designed to take high-resolution images of the surface of Mars from orbit provide unprecedented image quality, resolution and coverage at sub-meter scales. The MRO will search for evidence of water, study the climate record, and identify landing sites for future missions. The MRO is scheduled for launch aboard an Atlas V rocket from Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The MRO is an important next step in fulfilling NASA’s vision of space exploration and ultimately sending human explorers to Mars and beyond.

KENNEDY SPACE CENTER, FLA. - The Space Shuttle Columbia, undergoing final preparations for launch at Pad 39A, is reflected in the waters of the nearby ocean lagoon. The Rotating Service Structure is in the retracted position for launch.

KENNEDY SPACE CENTER, FLA. - KSC Deputy Director Woodrow Whitlow Jr. (left) escorts distinguished guests to the VIP viewing site at NASA Kennedy Space Center. First Lady Laura Bush is in front (right) with Noelle Bush, the daughter of Florida Gov. Jeb Bush and Columba Bush behind her. They are attending the historic launch of Space Shuttle Discovery on Return to Flight mission STS-114, scheduled to lift off at 10:39 a.m. EDT from Launch Pad 39B with a crew of seven. Mrs. Bush is only the third First Lady to witness a Space Shuttle launch at KSC. On this mission to the International Space Station the crew will perform inspections on-orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure. The 12-day mission is expected to end with touchdown at the Shuttle Landing Facility on Aug. 7.

KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility, the Hyster lift backs away from the orbiter Discovery after placing a Space Shuttle Main Engine (SSME) into position for installation. Discovery is the vehicle designated for the Return to Flight mission STS-114. Overall, an SSME weighs approximately 7,000 pounds. An SSME operates at greater temperature extremes than any mechanical system in common use today. The liquid hydrogen fuel is -423 degrees Fahrenheit, the second coldest liquid on Earth. When the hydrogen is burned with liquid oxygen, the temperature in the engine's combustion chamber reaches +6000 degrees Fahrenheit -- that's higher than the boiling point of Iron. The maximum equivalent horsepower developed by the three SSMEs is just over 37 million horsepower. The energy released by the three SSMEs is equivalent to the output of 23 Hoover Dams.

KENNEDY SPACE CENTER, FLA. - The NOAA (National Oceanic and Atmospheric Administration) weather station, seen here at the Shuttle Landing Facility’s midfield on NASA’s Kennedy Space Center in Florida, has a new neighbor. A climate-observing network that will drastically improve the nation's awareness of how weather impacts our lives has been established at the site. NASA, NOAA and the U.S. Air Force will work together on the U.S. Climate Reference Network, which will examine climate trends and change throughout the nation and its surrounding regions for the next 50 years. Instruments that are being provided include a solar radiation measuring device and an infrared surface temperature instrument. This gives Kennedy a unique opportunity to compare its sensor system with the NOAA site that is approximately 100 feet away.

KENNEDY SPACE CENTER, FLA. - In the back transfer aisle of the Orbiter Processing Facility bay 3, a worker checks paperwork for the Thermal Protection System (TPS) blanket to be wrapped around the Orbiter Boom Sensor System (OBSS). The installation of the insulation concludes TPS closeout prior to installation of the boom in the orbiter Discovery. The OBSS is one of the new safety measures for Return to Flight, equipping the Shuttle with cameras and laser systems to inspect the Shuttle’s Thermal Protection System while in space. Discovery is designated as the Return to Flight vehicle for mission STS-114, with a launch window of May 12 to June 3, 2005.

KENNEDY SPACE CENTER, FLA. -- With STS-110 Mission Specialists Jerry Ross (far left) and Steven Smith (third from left) on board, Commander Michael Bloomfield scatters dust as he practices driving the M-113 armored personnel carrier. The driving is part of Terminal Countdown Demonstration Test activities, which include emergency egress training and a simulated launch countdown. The TCDT is held at KSC prior to each Space Shuttle flight. Scheduled for launch April 4, the 11-day mission will feature Shuttle Atlantis docking with the International Space Station (ISS) and delivering the S0 truss, the centerpiece-segment of the primary truss structure that will eventually extend over 300 feet
