The Parker Solar Probe is a NASA observatory spacecraft investigating the Sun’s outer atmosphere, the corona. Launched in 2018, it utilizes an innovative design to repeatedly approach closer to the Sun than ever before. This allows scientists to study solar activity and its effects on the heliospher...
SOHO is a space-based observatory operated jointly by NASA and the European Space Agency. It monitors the Sun’s activity, including solar flares and coronal mass ejections, providing crucial data for understanding these events and their impact on Earth's space environment. Scientists studying heliop...
The Solar Dynamics Observatory (SDO) is a space-based observatory operated by NASA. It provides continuous ultraviolet imaging of the Sun, allowing scientists to study solar flares, coronal mass ejections, and other energetic events. This data is crucial for understanding how the Sun impacts Earth’s...
The Advanced Composition Explorer (ACE) is a NASA space mission designed to study the composition of matter from the solar wind and cosmic rays. Launched in 1997, the spacecraft operates at the Sun-Earth L1 Lagrange point, where the gravitational forces of the Earth and the Sun are balanced. Its sui...
STEREO (Solar TErrestrial RElations Observatory) is a NASA solar observation mission launched in 2006. It utilizes two nearly identical spacecraft placed in heliocentric orbits ahead of and behind Earth. This orbital configuration allows the observatories to capture stereoscopic images of the Sun an...
TIMED (Thermosphere, Ionosphere, Mesosphere, Energetics, and Dynamics) is a NASA heliophysics mission launched in 2001 to study the boundary between Earth's lower atmosphere and space. The spacecraft investigates how solar energy and chemical dynamics influence the Mesosphere and Lower Thermosphere/...
