Space Ark.

It's 6 months, 1 week, and 4 days since the earth was destroyed by an asteroid. 200 humans survive on board a huge 'Space Ark'. Their mission? To find a new planet where the human race can be re-established. The ship is populated by the finest minds the earth had to offer, plus an inept crew, an android-bear pilot and a member of the public who won his place by lottery. In the pilot episode the crew encounter a seemingly friendly alien race, whose space craft has broken down. What could possibly go wrong?
