It’s about a year until ICON launches, and all teams—science, instruments, mission operations and modeling teams—are moving forward with laser focus. There is little time to rest when so much goes into making a NASA satellite ready for launch in June 2017. Systems need to be tested to ensure they can download and process the data that ICON will be generating nearly continuously, orbit after orbit, in Earth’s upper atmosphere. Current data processing testing is making use of the data that the flight instruments are already producing as they undergo ground testing—it's a great way to see how everything's flowing through the data pipeline. In fact, the mission and instrument operations teams worked together recently to perform a “day in the life” test with the instruments, where they ran them through a 24 hour long sequence of commands, to simulate what they will do over a full day's worth of orbits.
