ACE (Advanced Composition Explorer)

The Advanced Composition Explorer (ACE) is a NASA spacecraft launched in 1997 that studies particles and magnetic fields from the Sun and space. Positioned near Earth’s orbit, it collects data on solar wind, energetic particles, and cosmic rays, helping scientists understand solar activity and space weather. This information can impact satellite operations, communications, and power grids on Earth. By monitoring the Sun’s behavior in real-time, ACE helps provide early warnings of solar storms, aiding to protect technology and astronauts in space. It’s a vital tool for understanding how the Sun influences our space environment.
