Jet Propulsion Laboratory - Managed for NASA by the California Institute of Technology, JPL is the leading U.S. center for robotic exploration of the solar system. NASA's Origins Program - Seeks to answer the fundamental questions about the Universe: Are we alone in the Universe? How did we get here? What is the origin of the Universe? Is there another Earth-like planet in our celestial neighborhood? Ocean Surface Topography from Space - Seeks to study the sea surface height. Maintaining a database of ocean surface topography can help predict short-term changes in weather and longer-term patterns of climate. JPL DIAL - NASA's Jet Propulsion Lab Digital Image Animation Laboratory is an advanced computer animation, and software engineering facility with broadcast quality video recording and editing capabilities. The DIAL was created and is continually developed by the Visualization and Earth Science Applications group. MASTER - The MODIS/ASTER Airborne Simulator - The primary objective is to support the ASTER and MODIS instrument teams in the areas of algorithm development, calibration and validation. ASTER: Advanced Spaceborne Thermal Emission and Reflection Radiometer - A high resolution imaging instrument that is flying on the Terra satellite. Obtains detailed maps of land surface temperature, emissivity, reflectance and elevation of the Earth. Near-Earth Object Program - Established in mid-1998 to help coordinate, and provide a focal point for, the study of those comets and asteroids that can approach the Earth's orbit. Near-Earth Asteroid Tracking (NEAT) - An autonomous celestial observatory developed by the Jet Propulsion Laboratory and funded by NASA to study asteroids and comets. The facility is a cooperative effort between the NASA Jet Propulsion Laboratory and the United States Air Force designed to complete a comprehensive search of the sky for near-Earth asteroids and comets. Asteroid Radar Research - This web site is primarily a data-organization and communications tool that supports ongoing research by JPL scientists and our colleagues. JPL Solar System Dynamics - Provides detailed information related to known bodies in orbit around the sun. Ephemerides, physical parameters, Earth close-approaches, observer tools, etc. Deep Space Network (DSN) - NASA's worldwide antenna network to support the exploration of the solar system. Mars Exploration Rover Mission - Latest news, press releases, and photos from Spirit and Opportunity. Laser Interferometer Space Antenna -- LISA - The NASA mission studies the mergers of supermassive black holes, tests Einstein's Theory of General Relativity, probes the early Universe, and searches for gravitational waves——the primary objective. Jet Propulsion Laboratory: Table Mountain Facility - Scientific and engineering research facility. Projects, accommodations, history, and staff contacts. Wrightwood, California.
