美发射三枚新探测器 研究太阳风与空间天气

Core Points - NASA and NOAA launched three space probes to study solar wind and space weather impacts on Earth and the solar system [1][2] - The probes include NASA's Interstellar Mapping and Acceleration Probe (IMAP), the Karelian Coronagraph, and NOAA's Space Weather Follow-On satellite SWFO-L1 [1] - The launch occurred on September 24, 2023, at 7:30 AM ET from Kennedy Space Center, with the probes expected to reach the first Lagrange point in January 2024 [1] Group 1 - The IMAP mission will focus on studying the solar wind boundary region and its interactions with nearby galaxies, providing real-time monitoring of solar wind and high-energy particles [1] - Data from IMAP will enhance predictive capabilities regarding space weather impacts, helping to prevent issues like power grid failures and satellite malfunctions caused by solar storms [1] Group 2 - The Karelian Coronagraph is a small satellite named after American space physicist George Karelian, which will continuously observe the Earth's outer atmosphere, the exosphere, to understand its characteristics and changes over time [2] - The SWFO-L1 satellite will monitor solar activity and solar wind in real-time, providing critical data and early warning for potentially destructive space weather events affecting Earth [2]
