Season 1, Episode 26 - "Shockwave Part 1"
22 May, 2002
Enterprise discovers a mining colony of the Paraagans. The crew gets an invitation for a meeting on the surface and a shuttle pod tries to break through the atmosphere. All of the sudden a giant explosion begins just under the shuttle and scorches the earth beneath. All 3600 colonists are reported dead. After examination Enterprise finds the explosion was caused by the shuttle igniting the atmosphere, but Lieutenant Reed is sure he closed the plasma vents that would have led to the ignition. After conversations with admiral Forrest of Starfleet Command, captain Archer learns Enterprise' mission is canceled and they must return home, not to return to space for another ten or twenty years. When the ship has altered course, crewman Daniels, a time traveler, pays a visit to captain Archer and tells him things are not as they seem.
