Star Trek: Enterprise - Terra Nova Season 1 Episode 6
Over 75 years ago the spaceship Conestoga left Earth on a nine-year one-way mission to establish the first human colony outside the solar system, called Terra Nova. The colony thrived on their beautiful new planet, and was such a success the Space Agency on Earth decided to send another vessel. The colonists protested and angry messages were traded, then one day all transmissions from Terra Nova ceased. Decades later the Warp 5-capable Enterprise NX-01 is dispatched to find out what happened to that lost colony.
