Thanks Cpt Ric and Frewfrux for asking these questions -- I had exactly the same question.
To make the jump cost abundantly clear to me...is this correct?:
My ship has a

of 1 and I'm pursuing a contract with

3. When I first decide to pursue the contract, I draw one card from the top of my deck, see it's 2

, discard it, draw another card, see it's 1

, discard it, and now I'm effectively "on site". Correct? (And instead of drawing cards from my deck, I could have also used cards from my hand)
