HETE-2 (Explorer 79) →. IMAGE ( Imager for Magnetopause-to-Aurora Global Exploration, Explorer 78 or MIDEX-1) is a NASA Medium Explorer mission that studied the global response of the Earth's magnetosphere to changes in the solar wind. It was believed lost but as of August 2018 might be recoverable.
NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite ( TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [6] It was launched on 18 April 2018, atop a Falcon 9 launch vehicle and ...
Wide-field Infrared Survey Explorer. Wide-field Infrared Survey Explorer ( WISE, observatory code C51, Explorer 92 and MIDEX-6) is a NASA infrared astronomy space telescope in the Explorers Program launched in December 2009. [2] [3] [4] WISE discovered thousands of minor planets and numerous star clusters.
Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field.High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data for modelling the geomagnetic field and its interaction with other physical aspects of the ...
STEREO ( Solar TErrestrial RElations Observatory) is a solar observation mission. [2] Two nearly identical spacecraft ( STEREO-A, STEREO-B) were launched in 2006 into orbits around the Sun that cause them to respectively pull farther ahead of and fall gradually behind the Earth.
PACE mission logo. Plankton, Aerosol, Cloud, ocean Ecosystem ( PACE) is a NASA Earth-observing satellite mission that will continue and advance observations of global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE will be used to identify the extent and duration of phytoplankton blooms and ...
Interstellar Boundary Explorer ( IBEX or Explorer 91 or SMEX-10) is a NASA satellite in Earth orbit that uses energetic neutral atoms (ENAs) to image the interaction region between the Solar System and interstellar space. The mission is part of NASA's Small Explorer program and was launched with a Pegasus-XL launch vehicle on 19 October 2008. [3]
For the U.S. Army training course, see Ranger School. The Ranger program was a series of uncrewed space missions by the United States in the 1960s whose objective was to obtain the first close-up images of the surface of the Moon. The Ranger spacecraft were designed to take images of the lunar surface, transmitting those images to Earth until ...
