VANDENBERG AIR FORCE BASE, Calif. – The second stage for NASA's Orbiting Carbon Observatory-2 mission, or OCO-2, is suspended from the ceiling of the high bay of the Building 836 hangar on Vandenberg Air Force Base in California following its removal from the transportation trailer in which it arrived. OCO-2 is scheduled to launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 in July. The rocket's second stage will insert OCO-2 into a polar Earth orbit. OCO-2 will collect precise global measurements of carbon dioxide in the Earth's atmosphere and provide scientists with a better idea of the chemical compound's impacts on climate change. Scientists will analyze this data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important atmospheric gas.

VANDENBERG AIR FORCE BASE, Calif. – The lid is removed from the transportation trailer containing the fairing for NASA's Soil Moisture Active Passive mission, or SMAP, in the Building 836 high bay on Vandenberg Air Force Base in California. The fairing will protect the SMAP spacecraft from the heat and aerodynamic pressure generated during its ascent to orbit aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2. SMAP will provide global measurements of soil moisture and its freeze/thaw state. These measurements will be used to enhance understanding of processes that link the water, energy and carbon cycles, and to extend the capabilities of weather and climate prediction models. SMAP data will also be used to quantify net carbon flux in boreal landscapes and to develop improved flood prediction and drought monitoring capabilities. Launch is scheduled for November 2014.

KENNEDY SPACE CENTER, FLA. -- The canister containing the U.S. laboratory module, intended for the International Space Station, sits on a flatbed trailer after being removed from NASA's "Super Guppy" aircraft that brought it from Marshall Space Flight Center, Huntsville. The lab is being transferred to the Space Station Processing Facility for pre-launch preparations. Scheduled for launch aboard the Shuttle Endeavour on mission STS-98, the laboratory comprises three cylindrical sections with two end cones. Each end-cone contains a hatch opening for entering and exiting the lab. The lab will provide a shirtsleeve environment for research in the areas of life science, microgravity science, Earth science and space science. Designated Flight 5A, this mission is targeted for launch in early 2000

KENNEDY SPACE CENTER, FLA. -- In Hangar M on Cape Canaveral Air Force Station in Florida, the United Launch Alliance Delta II first stage is revealed after the cover was removed from the truck trailer that delivered it. The Delta rocket will be used to launch the Gamma-Ray Large Area Space Telescope, or GLAST, in May from Launch Pad 17-B on CCAFS. The GLAST is a powerful space observatory that will explore the Universe's ultimate frontier, where nature harnesses forces and energies far beyond anything possible on Earth; probe some of science's deepest questions, such as what our Universe is made of, and search for new laws of physics; explain how black holes accelerate jets of material to nearly light speed; and help crack the mystery of stupendously powerful explosions known as gamma-ray bursts.

The Mars Odyssey spacecraft is maneuvered for removal from the Air Force C-17 cargo airplane that brought it from Denver, Colo.., location of the Lockheed Martin plant where the spacecraft was built. Mars Odyssey will be moved on a transport trailer from KSC's Shuttle Landing Facility to the Spacecraft Assembly and Encapsulation Facility 2 (SAEF-2) located in the KSC Industrial Area. In the SAEF it will undergo final assembly and checkout. This includes installation of two of the three science instruments, integration of the three-panel solar array, and a spacecraft functional test. It will be fueled and then mated to an upper stage booster, the final activities before going to the launch pad. Launch is planned for April 7, 2001 the first day of a 21-day planetary window. Mars Odyssey will be inserted into an interplanetary trajectory by a Boeing Delta II launch vehicle from Pad A at Complex 17 at the Cape Canaveral Air Force Station, Fla. The spacecraft will arrive at Mars on Oct. 20, 2001, for insertion into an initial elliptical capture orbit. Its final operational altitude will be a 250-mile-high, Sun-synchronous polar orbit. Mars Odyssey will spend two years mapping the planet's surface and measuring its environment

CAPE CANAVERAL, Fla. -- The multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory (MSL) mission, enclosed in the mesh container known as the "gorilla cage," is removed from its trailer outside the Vertical Integration Facility at Space Launch Complex 41. The generator will be lifted up to the top of the rocket and installed on the MSL spacecraft, encapsulated within the payload fairing. The MMRTG will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. Heat produced by this natural decay will provide constant power through the day and night during all seasons. MSL's components include a car-sized rover, Curiosity, which has 10 science instruments designed to search for signs of life, including methane, and help determine if the gas is from a biological or geological source. Heat emitted by the MMRTG will be circulated throughout the rover system to keep instruments, computers, mechanical devices and communications systems within their operating temperature ranges. Launch of MSL aboard a United Launch Alliance Atlas V rocket is targeted for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station.

VANDENBERG AIR FORCE BASE, Calif. -- A forklift is enlisted to transfer NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), enclosed in an environmentally controlled shipping container, from the tractor-trailer on which it arrived into the airlock of processing facility 1555 at Vandenberg Air Force Base (VAFB) in California. The spacecraft arrived at 7:52 a.m. PST after a cross-country trip from Orbital Sciences' manufacturing plant in Dulles, Va., which began Jan. 24. The spacecraft will be offloaded into the processing hangar, joining the Pegasus XL rocket that is set to carry it to space. After NuSTAR is removed from its shipping container, checkout and other processing activity will begin. The spacecraft will be integrated with the Pegasus in mid-February and encapsulation in the vehicle fairing will follow. After processing is completed, the rocket and spacecraft will be flown on Orbital's L-1011 carrier aircraft to the Ronald Reagan Ballistic Missile Defense Test Site at the Pacific Ocean's Kwajalein Atoll for launch in March. The high-energy x-ray telescope will conduct a census for black holes, map radioactive material in young supernovae remnants, and study the origins of cosmic rays and the extreme physics around collapsed stars.

CAPE CANAVERAL, Fla. -- Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, a ground support technician helps position one of the sprocket shaft assemblies onto a cradle as an overhead crane lowers it down. The sprocket assembly was removed from the C truck of crawler-transporter 2, or CT-2. They will be placed into shipping cradles on pallets and positioned on a flatbed trailer. They will be sent to a vendor for inspections and refurbishment. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad.

The X-59 arrives in Fort Worth, Texas from Palmdale, California, ready to undergo some important structural and fuel tests at the Lockheed Martin facility. The bright blue wrap around the X-plane is a precautionary measure to keep the exterior of the X-59 safe as it traveled through multiple states on its way to Texas.
