Sample Character Sheet:

Name: Harold Sampson
Sex: Male
Age: 32
Planet of origin: Earth
Position/Rank: Captain/pilot/geologist
Skills: Geology, piloting, meteorology, basic stellar physics (to fly through space, you have to have it.), inorganic chemistry, basic quantum physics.
Personality: Analytical, precise. He likes to analyze a situation as fully as possible before making a decision. He demands excellence of himself and, to a lesser extent, of those under his command.
Why did they come on this mission, knowing they might never return to Earth? "It is difficult to truly excel when billions of others are around to try to surpass you. Sure, there is the additional drive caused by competition, but those who can't excel make it harder for the ones that can, generally with laws, rather than competition, as they have numbers on their side."
History/Story: He grew up in a large city, seeing his parents always try to scrape by at a factory, or an office, or wherever they worked. He decided that that wasn't for him, so even as a child he pushed himself harder than any other child. When he graduated from high school as Valedictorian, he went to college on a scholarship, studying mineralogy, hoping to get a position on one of the colonist ships heading to Mars, where he would search for minerals. When it came down to recruiting people, however, he was overqualified for the position he wanted, and they didn't need another scientist of his caliber yet.
He got a job working for one of the under-water mineral survey corporations, analyzing the data of the probes to better guide them in their search. He worked there for several years until he learned of the colony program, sending a few ships of humans through the wormhole to colonize a new world, he signed up.

Name: Phil Green
Sex: Male
Age: 26
Planet of Origin: Mars
Position/Rank: Co-pilot/engineer
Skills: piloting, stellar and quantum physics, electrical engineering, Aerospace engineering
Personality: Determined. He may not always succeed, but he always tries his best.
Why did they come on this mission, knowing they might never return to Earth? "I'm not from Earth, but that doesn't matter. I don't want to die, just being a worker on a world of workers. This colony will let be be myself, the best "me" I can be. My life will have meaning."
History/Story: He grew up on Mars, the son of a ship repair technician and a hydroponics worker. Like most people on Mars, his parents weren't very monogamous (a cultural trait of the Martians, as it diversifies the gene pool), and therefore never got married, but that didn't matter. He started living with his dad at the age of ten, which is when he discovered his love for machines. By the age of twelve, he was helping his dad fix ships, and by the age of sixteen he had officially joined the maintenance staff at the dock.
He worked on his education while trying to save up enough money to buy his own cargo ship, or at least be a partial owner of one. When he learned of the colonization efort on Earth, though, he spent his savings on treatments and rehabilitation to readjust his body to Earth-normal gravity. Once he was finished, he took a shuttle to Earth to join up.

Name: Janet Yealor
Sex: Female
Age: 28
Planet of Origin: Earth
Position/Rank: Medical officer/biologist
Skills: medicine, surgery, cellular biology
Personality: annoyed, bored. She is always looking for a challenge, but claims to have never found one.
Why did they come on this mission, knowing they might never return to Earth? "Maybe a place where humans have never been, but is filled with life, will test my skills."
History/Story: A Military brat, United North American Army was easy. She studied to be a doctor, as she had always liked studying the mystery that was life, and became a battlefield surgeon on the frontlines in the war against the Middle Eastern Alliance, a war precipitated by the coup that placed terrorist leaders at the head of the Alliance. There she made a name for herself finding cures for the outcome of the use of ever-more-clever biological, chemical, and radiological weapons. She, however, found it a bit boring, the only times she really pushed herself being the first 18-24 hours of a new pathogenic outbreak.
The colonization effort offered her something she couldn't find anywhere else, millions or billions of new, possibly hostile, lifeforms.

Name: Angeline La'Rouche
Sex: [s]I don't really know you that well.[/s] Female
Age: 29
Planet of Origin: Earth
Position/rank: Architect/structural engineer
Skills: Architecture, Painting, Music, History (ancient world), structural engineering, materials tech (building materials and artistic materials)
Personality: Joker. She takes few things that aren't dangerous seriously. One must be careful what they say around her, lest she twist what they say.
Why did they come on this mission, knowing they might never return to Earth? "Are you kidding? It's an entirely new world, with new challenges, and I get to be instrumental in the development of it's style for generations to come."
History/story: She grew up in the suburbs, and went to college on a music scholarship, playing violin in the schools symphony. There she studied architecture, with a minor in ancient history, believing that the Greeks and Romans were some of the best architects in history. When she graduated, she designed buildings for the many growing cities and towns around the world. She never felt like she had a truly blank canvas, to produce her art with, so when the colonization effort started, she signed up, hoping that a new world would be a much more open medium for her art.
