Mission: Space opened in 2003 in what was then Future World East(now World Discovery), in the location originally occupied by the Horizons pavilion. Mission: Space is a motion simulator attraction that allows guests to experience astronaut training for the first manned trip to Mars. After riding Mission Space guests can explore the Advanced Training Lab which features a competition game and interactive exhibits.

The fastest attraction in Disney World, Test Track opened on December 19, 1998 in what was then Future World East(now World Discovery). Test Track replaced the World of Motion attraction, which had been open from 1982 until 1996. The attraction allows guests to design their own cars and then test them on the "SimTrack". The apex of the attraction is a 65 MPH speed test that concludes the attraction. General Motors has sponsored the pavilion in both its World of Motion and Test Track forms.
