Astley Spakes is a sexy doctor on board the Raptor, and part of its elite hitsquad. His drive is to meet sexy aliens (though he is not opposed to becoming captain).
He is “best characterized by a man leaning back with his arms crossed” and, on the scale of Brad Pitt to George Clooney, is closer to the Brad Pitt end. He is described as being slightly older and slightly tan, with an angular nose, and having three day’s worth of beard. He has short, thick black hair which is about 20% grey hair, with more grey in his beard than his hair. He has a slightly receding hairline, which he's not self conscious about, so it works.
