Launch Day: Solar Dynamics Observatory
This morning the Solar Dynamics Observatory, the first mission of the Living With A Star program, successfully launched this morning. It was a beautiful launch, covered on NASA TV and the SDO web site.
SDO's mission is to chronograph the Sun over the life of the probe, making a detailed record of it's variability, so we may understand more about how the Sun works and how it affects the Earth. SDO runs VxWorks on the flight computer, a radiation-hardened PowerPC RAD750. The science packages are Rad-Hard Coldfire chips running RTEMS.
I managed to come across a blog of a VxWorks developer / space enthusiast who was watching the launch this morning... (reprinted with permission from the original author).
