The Solar Radiation and Climate Experiment (SORCE) was a 2003–2020 NASA -sponsored satellite mission that measured incoming X-ray, ultraviolet, visible, near-infrared, and total solar radiation. [2] These measurements specifically addressed long-term climate change, natural variability, atmospheric ozone, and UV-B radiation, enhancing climate ...
The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [ 6 ] is a NASA space probe launched in 2018 with the mission of making observations of the outer corona of the Sun. It will approach to within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ][ 8 ] from the center of the Sun, and by 2025 will ...
The Terra satellite, launched in December 1999, carried two (Flight Module 1 (FM1) and FM2) and the Aqua satellite, launched in May 2002, carried two more (FM3 and FM4). A fifth instrument (FM5) was launched on the Suomi NPP satellite in October 2011 and a sixth (FM6) on NOAA-20 in November 2017. With the failure of the PFM on TRMM and the 2005 ...
Explorer 7. Explorer 7 was a NASA satellite launched on 13 October 1959, at 15:30:04 GMT, [1] by a Juno II launch vehicle from Cape Canaveral Air Force Station (CCAFS) to an orbit of 573 × 1,073 km (356 × 667 mi) and inclination of 50.27°. [2] It was designed to measure solar X-ray and Lyman-alpha flux, trapped energetic particles, and heavy ...
Advanced Composition Explorer (ACE or Explorer 71) is a NASA Explorer program satellite and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources. Real-time data from ACE are used by the National Oceanic and Atmospheric Administration (NOAA) Space Weather ...
The Space Weather Prediction Center is one of the nine National Centers for Environmental Prediction (NCEP) and provides real-time monitoring and forecasting of solar and geophysical events, conducts research in solar-terrestrial physics (i.e. heliophysics), and develops techniques for forecasting solar and geophysical disturbances.
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra (EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002. MODIS has now been replaced by the VIIRS ...
Because the solar EUV cannot be monitored from the ground, the joint NASA-ESA Solar and Heliospheric Observatory (SOHO) spacecraft was launched and has provided solar EUV images beginning in 1995. SOHO is a main source of near-real time solar data for both research and space weather prediction and inspired the STEREO mission.
