The Deep Space Climate Observatory (DSCOVR) is a space weather and Earth observation satellite launched in 2015 through a partnership between NOAA, NASA, and the U.S. Air Force. Positioned at the Sun-Earth L1 Lagrange point, it continuously monitors solar wind velocity and magnetic field to provide...
The Advanced Composition Explorer (ACE) is a NASA Explorer mission spacecraft launched in August 1997 to study matter from the solar wind and the interstellar medium. Positioned at the Earth-Sun Lagrange point 1 (L1), it orbits roughly 1.5 million kilometers from Earth, allowing it to sample energet...
Wind is a NASA science spacecraft launched on November 1, 1994, as part of the Global Geospace Science program. It was initially placed in a complex orbit that allowed it to sample the solar wind upstream of Earth before being moved to a stable position near the L1 Lagrange point, approximately 1.5...
DSCOVR (Deep Space Climate Observatory) is a NOAA and NASA Earth observation and space weather spacecraft launched on February 11, 2015, and stationed at the Sun–Earth L1 Lagrange point approximately 1.5 million kilometres from Earth. It carries instruments to monitor solar wind plasma and magnetic...
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...
Scheduled for launch by NASA in 2025, this heliophysics mission aims to map the boundary of the solar system and investigate the acceleration of energetic particles.
