Key Missions Advancing Heliosfera Research

Solar and Heliosfera Observatory (SOHO)

Launched in 1995, SOHO provides continuous observations of thee Sun 's corona and heliosfera. Its Large Angle and Spectrometric Coronagraph (LASCO) declots CMEs as early as 1,1 solar radii from the Sun' s surface. SOHO has discvered threats of comets and contribute to over 5,000 scientific papers. Its real- time date fears into space thalther prevention centers worldwide.

Operated by NOAA, DSCOVR sits at L1 and measures solar wind speed, density, temperatur, and magnetic field contricth. These measurements are critial for nowcasting geomagnetic storms. DSCOVR replaced the aging Advanced Composition Explorer (ACE) and provides 15- 60 minute advance warning of solar storms - enough time to power down sensitiva satellite instruments.
