Περίληψη:

Space weather is a fascinating applied-science field which has been rising in prominence since it is related to many real-world problems in astrophysics and engineering. Space weather has the potential to impact technologies in space and on the ground, and importantly place humans, such as astronauts and airline crews, at risk. Early warnings of solar and interplanetary activity are therefore valuable to spaceflight managers, satellite operators, electric power-grid managers, and others. NOAA, in collaboration with NASA, is planning for missions to several different orbits to cover these needs, starting with missions to Lagrange 1. I will discuss the Space Weather Follow On at Lagrange 1 (SWFO-L1) mission which will replace the earlier ACE, DSCOVR, and SOHO spacecraft to provide operational data including coronal images. Other NOAA initiatives include collaborations with ESA on the Vigil spacecraft to Lagrange 5, as well as other development of other missions for observations closer to Earth. I will discuss these programs with emphasis on the orbit design and physical measurements.
