Aquarius is a focused satellite mission to measure sea surface salinity (salt levels).
To explore the beginning of time, a "Big Bang Observer" will attempt to directly measure gravitons from the early universe still present today. The image at left comes from WMAP, which observed the Big Bang's "afterglow," the cosmic microwave background.
The goal of the Black Hole Imager mission will be to calculate the aspects of matter that fall into a black hole.
The Constellation-X Observatory is a combination of several X-ray satellites orbiting in close proximity to each other and working in unison to generate the observing power of one giant telescope.
The Beyond Einstein program has three linked elements which will be designed to observe two phenomena: to detect directly gravitational wave signals from the earliest possible moments of the Big Bang, and to image the event horizon of a black hole.
Glory will be the first mission dedicated to understanding the effects of aerosols and solar variability on climate.
GOES satellites provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.
The Global Precipitation Measurement mission is one of the next generation of satellite-based Earth science projects that will study global precipitation (rain, snow, ice) levels.
The James Webb Space Telescope is a large, infrared-optimized space telescope that is designed to study the earliest galaxies and some of the first stars formed after the Big Bang.
The Landsat Data Continuity Mission is the future of Landsat satellites. It will continue to obtain valuable data and Earth imagery to be used in agriculture, education, business, science and government.
As the first dedicated space-based gravitational wave observatory, the Laser Interferometer Space Antenna will detect waves generated by binary stars within our galaxy and by massive black holes in distant galaxies.
The NPOESS Preparatory Project Mission is designed to function as a bridge between the NASA EOS program and NPOESS for the development of Visible/Infrared Imager Radiometer Suite (VIIRS).
The Solar Dynamics Observatory will further our understanding of the sun's influence on Earth and near-Earth space by studying the solar atmosphere on small scales of space and time, and in many wavelengths simultaneously.
The Tracking and Data Relay Satellite System consists of a constellation of geosynchronous satellites and associated ground systems that operate as a bent-pipe relay system between customer platforms and customer ground facilities. Future TDRS satellites will help replenish the fleet.
