Board Game Contact: Signals from Outer Space

In the collaborative space adventure game Contact, you follow a signal while knowing neither exactly where it comes from, nor who sends it out. This signal wants to lead you to a certain planet, but instead of space coordinates, you receive only a strange sequence of flight instructions for your spaceship.

Can you identify the right target planet from this signal? And what will you find when you get there?

During the game, you follow a signal and travel from planet to planet. Each round a different player takes the role of 'the Source' of the signal. He wants his fellow players to reach the planet from where he is sending his signal. They, as the Crew, therefore have to decode the Sources signal which he performs as a kind of flight simulation using his hand with 'taps' as stopover landings on planets on the way.
In this cooperative game players loose if fuel runs out (6 incorrect guesses at the target planet), or win together if they managed to follow the signal with their rocket to 12 (different) planets.
The game includes a variant for professionals, and helper cards to adjust difficulty in addition to the starting difficulty
level.

The person giving hints can only 1) show the length of the flight by 2) how long he keeps his hand above the table
