The NASA Solar Dynamic Observatory (SDO) was successfully launched this morning. The SDO satellite includes 5 Radiation Hardened Coldfire CPUs running RTEMS. The Coldfire/RTEMS computers run many of the I/O functions and one of the instruments. A very nice graphic of the mission is here. The following is the description of the project from the SDO Project Site:
SDO: The Solar Dynamics Observatory is the first mission to be launched for NASA's Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.Congratulations to the folks at NASA Goddard on a successful launch and good luck in meeting their science goals. I look forward to the new insights we will gain into the Sun.
SDO's goal is to understand, driving towards a predictive capability, the solar variations that influence life on Earth and humanity's technological systems by determining
- how the Sun's magnetic field is generated and structured
- how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in the solar irradiance.
