Traveller LIFTOFF "Did you know..." challenge

We are picking up on an idea of one of our forum users: TrippyHippy

He suggested making Traveller LIFTOFF educational. While we probably won't print any equations it's a great idea to spark interest in physics and the world around us. So we will be inserting small fun facts in LIFTOFF such as this one:

"Did you know...
...that there's a permanent storm at Saturn's northpole in the shape of a perfect hexagon and so far no one as found out why?"
To get the best questions we are starting the Traveller LIFTOFF "Did you know..." challenge. You send us your "Did you know..." question and everyone who participates will take part in a drawing for a very limited PDF edition of Traveller Crew for Hire: Scientists. This limited edition will only feature Hiver and will not be sold anywhere. Only the five winners - whose name we will put inside - will have access to it and are free to spread it accross the community or keep it as a prized collectors edition to themselves.
Send your questions to This email address is being protected from spambots. You need JavaScript enabled to view it. with LIFTOFF as keyword. Deadline is 31 May 2014.
Good luck!
PS: TrippyHippy, your name is the challenge for the idea.
