Orbital LEOStar-2 and -3 spacecraft platforms are designed to support a variety of multispectral, visible and thermal imaging payloads. A list of commercial imaging satellites built by Orbital is provided next. GeoEye-1 (originally known as OrbView-5) OrbView-4 OrbView-3 OrbView-2 OrbView-1 Earlybird-1 Science and environmental satellites Orbital built Science and Environmental satellites conduct astrophysics, Remote sensing/Earth Observation, heliophysics, planetary exploration and technology demonstration missions. These satellites are built on Orbital's LEOStar-1,-2, or -3 satellite platforms depending on the mission requirements and budget. Astrophysics satellites Orbital's current and heritage astrophysics satellites are as listed below: Transiting Exoplanet Survey Satellite (TESS) for NASA/ MIT- launched in 2018 Nuclear Spectroscopic Telescope Array (NuSTAR) for NASA/ JPL- launched in 2012 Fermi Gamma-ray Space Telescope for NASA GSFC- launched in 2008 Swift Gamma-Ray Burst Mission for NASA GSFC- launched in 2004 Galaxy Evolution Explorer (GALEX) for NASA GSFC- launched in 2003 Far Ultraviolet Spectroscopic Explorer (FUSE) for NASA/ Johns Hopkins University- launched in 1999 Extreme Ultraviolet Explorer (EUVE) for NASA- launched in 1992 Remote sensing/Earth observation Orbital's current and heritage Remote Sensing/Earth Observation satellites are as listed below: Ionospheric Connection Explorer (ICON) for NASA GSFC- launched in 2019 Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) for NASA GSFC- launched in 2018 Orbiting Carbon Observatory-2 (OCO-2) for NASA/JPL- launched in 2014 Landsat 8 for NASA/USGS- launched in 2013 Glory for NASA GSFC- launched in 2011 (did not achieve orbit due to a launch failure) Orbiting Carbon Observatory (OCO) for NASA/JPL- launched in 2009 (did not achieve orbit due to a launch failure) Aeronomy of Ice in the Mesosphere (AIM) for NASA/Hampton University- launched in 2007 FORMOSAT-3/COSMIC for National Space Organization Taiwan- launched in 2006 Coriolis for Naval Research Laboratory and Air Force Research Laboratory- launched in 2003 QuikTOMS for NASA GSFC- launched in 2001 (did not achieve orbit due to a launch failure) SeaStar for NASA/ORBIMAGE- launched in 1997 MicroLab-1 for NASA/UCAR- launched in 1995 TOPEX/Poseidon for NASA/CNES (France)- launched in 1992 Upper Atmosphere Research Satellite (UARS) for NASA- launched in 1991 Landsat 5 for NASA/USGS- launched in 1984 (the satellite holds Guinness World Record for longest operating earth observing satellite) Landsat 4 for NASA/USGS- launched in 1982 Heliophysics Orbital's heritage Heliophysics satellites are as listed below: Interstellar Boundary Explorer (IBEX) for NASA/SwRI- launched in 2008 Solar Radiation and Climate Experiment (SORCE) for NASA/LASP- launched in 2003 Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) for NASA/
