    NASA Insignia NASA→ Read the press releases that are being released throughout the agency.
    Phoenix The Phoenix Mars Lander→ will target the Martian arctic and use a robotic arm to dig through the protective top soil layer to the water ice below and ultimately, to bring both soil and water ice to the lander platform for sophisticated scientific analysis.
    MOFFETT FIELD, Calif. -- Engineering teams are conducting final checkouts of the Lunar Crater Observation and Sensing Satellite, known as LCROSS, that will take a significant step forward in the search for water on the moon. The Mission Objectives of the Lunar Crater Observation and Sensing Satellite (LCROSS)→ include confirming the presence or absence of water ice in a permanently shadowed crater at the Moon’s South Pole.
    Picture of Moon Lunar Atmosphere and Dust Environment Explorer (LADEE)→ is a NASA mission that will orbit the Moon and its main objective is to characterize the atmosphere and lunar dust environment.
    Presat is a risk reduction and technology demonstration mission. The PreSat→ nanosatellite contains a laboratory that will use innovative environment control techniques to test space science capabilities after it is launched into orbit.
    The NanoSail-D mission will track the progress of NASA's first solar sail created for nanosatellites. The NanoSail-D mission→ will track the progress of NASA's first solar sail created for nanosatellites.
    The Lunar Reconnaissance Orbiter mission will conduct investigations that will prepare for and support future human exploration of the Moon. The Lunar Reconnaissance Orbiter→ mission will conduct investigations that will prepare for and support future human exploration of the Moon.
    CoLab NASA CoLab→ serves as an advisor and consultant to groups within NASA, building direct and open collaborations between the public, and NASA scientists and engineers.
    Kepler Kepler→ is NASA's first mission capable of finding Earth-sized and smaller planets around other stars.
    TESS Scientists and engineers at NASA’s Ames Research Center are contributing to the work on Transiting Exoplanet Survey Satellite (TESS)→ which will be studying Earthlike planets around nearby stars.
    Astrobiology The mission of the NASA Astrobiology Institute→ is to study the origin, evolution, distribution, and future of life on Earth and in the Universe.
    PharmaSat The PharmaSat→ experiment and flight system will be designed to measure the influence of microgravity upon yeast resistance to an antifungal agent.
    Mars Exploration Rover The Mars Exploration Rover→ mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet.
    Jason-1 Jason-1→ completes its 5th year on orbit on 7 December 2006. From its vantage point 1,330 kilometers (860 miles) above Earth, this follow-on to the highly successful TOPEX/Poseidon mission has provided measurements of the surface height of the world's oceans to an accuracy of 3.3 centimeters (1.3 inches).
    The Cassini spacecraft arrived at Saturn in 2004 following a 7-year, 2.2 billion mile journey. While in orbit, Cassini is sending back data on the planet, its many moons and magnificent rings. Cassini also delivered the Huygens probe to the surface of Saturn's moon Titan in January 2005. The Cassini→ spacecraft arrived at Saturn in 2004 following a 7-year, 2.2 billion mile journey.

    STS-124 Navy Cmdr. Mark E. Kelly commanded the STS-124→ shuttle mission to deliver the Pressurized Module and robotic arm of the Japanese Experiment Module, known as "Kibo" (hope), to the International Space Station.
    Hubble Space Telescope Named after the trailblazing astronomer Edwin P. Hubble (1889-1953), the Hubble Space Telescope (HST)→ is a large, space-based observatory which has revolutionized astronomy by providing unprecedented deep and clear views of the Universe, ranging from our own solar system to extremely remote fledgling galaxies forming not long after the Big Bang 13.7 billion years ago.
    NASA GLAST GLAST→ is a powerful space observatory that will explore the most extreme environments in the universe, and search for signs of new laws of physics and what composes the mysterious dark matter, explain how black holes accelerate immense jets of material to nearly light speed, and help crack the mysteries of the staggeringly powerful explosions known as gamma-ray bursts.
    NASA Earth Observatory The purpose of NASA’s Earth Observatory→ is to provide a freely-accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet.
    NASA Solar Dynamics Observatory NASA SDO HMI→ Read the latest information about solar flares, missions, and other recent developments from NASA, SOHO, and MDI.
    Desert RATS The Desert RATS→ field test activity is the culmination of the various individual science and advanced engineering discipline areas year-long technology and operations development efforts into a coordinated field test demonstration under representative (analog) planetary surface terrain conditions.
