Why we love space

OK – we agree it's not exactly the same as other, more famous 'GO/NOGO' roll calls – but we still think this is pretty cool!

This is the pre-launch GO/NOGO roll call in the Main Control Room at ESOC, 13 December 2013. The roll call was conducted by Flight Director Andreas Rudolph just prior to the Centre declaring itself ready to support Gaia liftoff, which took place at 09:12GMT / 10:12 CET.
