... 1.3 Diffuse Interstellar Clouds Diffuse clouds are dominated by photochemistry. Such clouds have moderate extinctions (<1 mag) and densities of roughly 100-300 cm-3. Interstellar extinction is measured in magnitude (mag) at a given wavelength and reflects the starlight which is absorbed and scattere ...

THE SOLAR WIND INTERACTION WITH VENUS AND MARS
... ENA is large enough so that we can ignore gravity effects. Then the ENAs travel in straight lines since they are unaffected by magnetic and electric fields. Near Mars and Venus there are several processes that produce ENAs. Solar wind protons interact directly with the planetary neutrals and produce ...

Advanced Composition Explorer

Advanced Composition Explorer (ACE) is a NASA Explorers program Solar 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 is used by the NOAA Space Weather Prediction Center to improve forecasts and warnings of solar storms. The ACE robotic spacecraft was launched August 25, 1997 and entered a Lissajous orbit close to the L1 Lagrangian point (which lies between the Sun and the Earth at a distance of some 1.5 million km from the latter) on December 12, 1997. The spacecraft is currently operating at that orbit. Because ACE is in a non-Keplerian orbit, and has regular station-keeping maneuvers, the orbital parameters at right are only approximate. The spacecraft is still in generally good condition in 2015, and is projected to have enough fuel to maintain its orbit until 2024. NASA Goddard Space Flight Center managed the development and integration of the ACE spacecraft.
