“We don’t have records prior to 1874 that give us details about the sun. Compared to the past 130 years, our sun now is unprecedented as far as how slow this Solar Cycle 24 is taking off - or not taking off!”
- David Hathaway, Ph.D., NASA Heliospheric Team Leader
October 30, 2009 Huntsville, Alabama - For twelve years, NASA has had a satellite positioned a million miles in front of Earth with the sun about 92 million miles beyond. Its mission has been to study particles that come near Earth from our sun, the solar system and the galaxy. The satellite is called Advanced Composition Explorer, or ACE, and some of the highly energetic particles ACE has been monitoring are cosmic rays.
