The 7-year journey to Saturn began with the liftoff of a Titan IVB/ Centaur carrying the Cassini orbiter and its attached Huygens probe. After a 2.2-billion mile journey that included two swingbys of Venus and one of the Earth to gain additional velocity, the two-story tall spacecraft will arrive at Saturn in July 2004. The orbiter will circle the planet for 4 years, its compliment of 12 scientific instruments gathering data about Saturn's atmosphere, rings and magnetosphere and conducting close-up observations of Saturnian moons. Huygens, with a separate suite of 6 science instruments, will separate from Cassini to fly on a ballistic trajectory toward Titan, the only celestial body besides Earth to have an atmosphere rich in nitrogen. Scientists are eager to study further this chemical similarity in hopes of learning more about the origins of our own planet Earth. Huygens will provide the first direct sampling of Titan's atmospheric chemistry and the first detailed photographs of its surface. The Cassini mission is an International effort involving NASA, the European Space Agency (ESA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI).

Atlas-1 flew in a series of Spacelab flights that measured long term variability in the total energy radiated by the Sun and determined the variability in the solar spectrum.

Jet Propulsion Research Lab (JPL) workers use a borescope to verify the pressure relief device bellow's integrity on a radioisotope thermoelectric generator (RTG) that has been installed on the Cassini spacecraft in the Payload Hazardous Servicing Facility. The activity is part of the mechanical and electrical verification testing of RTGs during prelaunch processing. RTGs use heat from the natural decay of plutonium to generate electrical power. The three RTGs on Cassini will enable the spacecraft to operate far from the Sun where solar power systems are not feasible. They will provide electrical power to Cassini on it seven year trip to the Saturnian system and during its four year mission at Saturn.

The journey back to Mars begins with a liftoff of the Mars Global Surveyor atop a Delta II 7925A expendable launch vehicle from the Cape Canaveral Air Station. After an approximate 10-month interplanetary odyssey, the spacecraft will arrive at Mars and begin a 4-month aerobreaking phase, an irnovative technique first demonstrated during the Magellan mission to Venus, to achieve a mapping orbit. It will take about 2 Earth years for Surveyor to circle above most of the planet, its suite of sophisticated remote-sensing instruments building a comprehensive global portrait of Mars by mapping its topography, magnetism, mineral composition and atmosphere. Among the locations the Surveyor will pass over are the landing sites where the two U.S. Viking landers have stood since 1975 as silent monuments to the most recent successful U.S. missions to Mars. The Global Surveyor is the first of a trio of spacecraft being launched to Mars; next is Russia's Mars `96 spacecraft, followed by the U.S.'s Mars Pathfinder.

Hinode (Sunrise), formerly known as Solar-B before reaching orbit, was launched from the Uchinoura Space Center in Japan on September 23, 2006. Hinode was designed to probe into the Sun’s magnetic field to better understand the origin of solar disturbances which interfere with satellite communications, electrical power transmission grids, and the safety of astronauts traveling beyond the Earth’s magnetic field. Hinode is circling Earth in a polar orbit that places the instruments in continuous sunlight for nine months each year and allows data dumps to a high latitude European Space Agency (ESA) ground station every orbit. NASA and other science teams will support instrument operations and data collection from the spacecraft’s operation center at the Japanese Aerospace Exploration Agency’s (JAXA’s) Institute of Space and Aeronautical Science facility located in Tokyo. The Hinode spacecraft is a collaboration among space agencies of Japan, the United States, the United Kingdom, and Europe. The Marshall Space Flight Center (MSFC) managed development of three instruments comprising the spacecraft; the Solar Optical Telescope (SOT); the X-Ray Telescope (XRT); and the Extreme Ultraviolet (EUV) Imaging Spectrometer (EIS). This image of a sunspot, taken by Hinode, is a prime example of what the spacecraft can offer.

An international effort to learn more about the complex interaction between the Earth and Sun took another step forward with the launch of WIND spacecraft from Kennedy Space Center (KSC). WIND spacecraft is studded with eight scientific instruments - six US, one French, and one - the first Russian instrument to fly on a US spacecraft - that collected data about the influence of the solar wind on the Earth and its atmosphere. WIND is part of the Global Geospace Science (GGS) initiative, the US contribution to NASA's International Solar Terrestrial Physics (ISTP) program.

Microbiologist Dr. Elena V. Pikuta, and Astrobiologist Richard Hoover culture extremophiles, microorganisms that can live in extreme environments, in the astrobiology laboratory at the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama. The scientists recently discovered a new species of extremophiles, Spirochaeta Americana. The species was found in Northern California's Mono Lake, an alkaline, briny oxygen-limited lake in a closed volcanic crater that Hoover believes may offer new clues to help identify sites to research for potential life on Mars. Hoover is an astrobiologist at NASA's Marshall Space Flight Center (MSFC), and Pikuta is a microbiologist with the Center for Space Plasma and Aeronomy Research Laboratory at the University of Alabama in Huntsville. The NSSTC is a partnership with MSFC, Alabama universities, industry, research institutes, and federal agencies.

This photo (rear view) is of one of many segments of the Eastman-Kodak mirror assembly being tested for the James Webb Space Telescope (JWST) project at the X-Ray Calibration Facility at Marshall Space Flight Center (MSFC). MSFC is supporting Goddard Space Flight Center (GSFC) in developing the JWST by taking numerous measurements to predict its future performance. The tests are conducted in a vacuum chamber cooled to approximate the super cold temperatures found in space. During its 27 years of operation, the facility has performed testing in support of a wide array of projects, including the Hubble Space Telescope (HST), Solar A, Chandra technology development, Chandra High Resolution Mirror Assembly and science instruments, Constellation X-Ray Mission, and Solar X-Ray Imager, currently operating on a Geostationary Operational Environment Satellite. The JWST is NASA's next generation space telescope, a successor to the Hubble Space Telescope, named in honor of NASA's second administrator, James E. Webb. It is scheduled for launch in 2010 aboard an expendable launch vehicle. It will take about 3 months for the spacecraft to reach its destination, an orbit of 940,000 miles in space.

In this photo, the Gravity Probe B (GP-B) space vehicle is being assembled at the Sunnyvale, California location of the Lockheed Martin Corporation. The GP-B is the relativity experiment developed at Stanford University to test two extraordinary predictions of Albert Einstein’s general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth’s rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. Launched April 20, 2004 , the GP-B program was managed for NASA by the Marshall Space Flight Center. Development of the GP-B is the responsibility of Stanford University along with major subcontractor Lockheed Martin Corporation. (Image credit to Russ Underwood, Lockheed Martin Corporation).
