NASA 3D Models: Aquarius

Aquarius is making NASA's first space-based global observations of ocean surface salinity, flying 657 kilometers (408 miles) above Earth in a sun-synchronous polar orbit that repeats every seven days. This NASA Earth System Science Pathfinder mission is mapping global changes in ocean surface salinity with a resolution of 150 kilometers (93 miles), showing how salinity changes from month to month, season to season and year to year. Scientists are combining Aquarius data with in-water measurements to generate operational maps of ocean salinity distribution.

NASA 3D Models: GRACE

GRACE (Gravity Recovery and Climate Experiment), twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems. These discoveries could have far-reaching benefits to society and the world's population.

NASA 3D Models: Hubble Space Telescope Servicing Mission 4 (SM4)

Hubble Space Telescope (HST) Servicing Mission 4 (SM4) Carriers: For more information about the carriers see http://asd.gsfc.nasa.gov/archive/sm4/multimedia/gallery3.html#carriers

NASA 3D Models: Aeronomy of Ice

AIM is a two-year mission to study Polar Mesospheric Clouds (PMCs), the Earth's highest clouds, which form an icy membrane 50 miles (80.4 km) above the surface at the edge of space.

NASA 3D Models: Vehicle Assembly Building (VAB)

The Vehicle Assembly Building (VAB) is one of the largest buildings in the world. It was originally built for assembly of Apollo/Saturn vehicles and was later modified to support Space Shuttle operations. Polygons: 3528 Vertices: 3388

NASA 3D Models: Advanced Crew Escape Suit

The Advanced Crew Escape Suit (ACES) is a full pressure vessel providing an atmosphere of protection. Polygons: 44656 Vertices: 44684

NASA 3D Models: Landsat 7

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. Since 1972, Landsat satellites have collected information about Earth from space.

NASA 3D Models: Aura

Aura observes the chemical content of the atmosphere to track the state of the ozone layer and the dispersion of airborne pollution. Polygons: 6 Vertices: 4

NASA 3D Models: OSTM/Jason-2

OSTM/Jason-2's primary payload includes five instruments similar to those aboard Jason-1, along with three experimental instruments. Its main instrument is an altimeter that precisely measures the distance from the satellite to the ocean surface. Its radiometer measures the amount of water vapor in the atmosphere, which can distort the altimeter measurements. Three location systems combine to measure the satellite's precise position in orbit.

NASA 3D Models: CloudSat

Launched in April 2006, CloudSat monitors the state of the Earth’s atmosphere and weather with a sophisticated radar system. The instrument, jointly developed with the Canadian Space Agency, can predict which clouds produce rain, observe snowfall, and monitor the moisture content of clouds.

NASA 3D Models: Cassini Assembly

Includes orbiter from CAD models. Accurate (to a fault) except no thermal blanketing is shown (this would cover most of the central structure of the spacecraft). Polygons: 478358 Vertices: 237633

NASA 3D Models: Terra

NASA launched the Earth Observing System's flagship satellite Terra, named for Earth, on December 18, 1999. Terra has been collecting data about Earth's changing climate.

NASA 3D Models: James Webb Space Telescope

The James Webb Space Telescope (JWST) will be a large infrared telescope with a 6.5-meter primary mirror. The project is working to a 2018 launch date. The JWST will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

NASA 3D Models: Global Hawk

The ability of the Global Hawk air vehicle to autonomously fly long distances and remain aloft for extended periods of time means that measuring, monitoring, and observing remote locations of the Earth's surface are now possible. Polygons: 19140 Vertices: 18620

NASA 3D Models: CALIPSO

The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite provides new insight into the role that clouds and atmospheric aerosols (airborne particles) play in regulating Earth's weather, climate, and air quality.

NASA 3D Models: AcrimSAT A

ACRIMSAT studies the sun's energy output with uniform sensitivity to improve knowledge of the sun's role in global change.

NASA 3D Models: Deep Impact

NASA 3D Models: Aqua

Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional variables also being measured by Aqua include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures.
