While you’re busy working on the ATV reboost homework questions posted by Rhett Allain (reminder: there are prizes!) – or if you’re looking for, uhmmm, a somewhat less challenging challenge – here is Question 1 in this week’s fabulous ATV-4 Mission Quiz (we’ll post three questions this week). Thanks to the team at EAC and especially ATV training specialist Lionel Ferra for the inspiration!

First, the intro crescendo…

And here’s Question 1:

ATV transports to the ISS

Hint: Both sources may be near the same city…
