Space Program is a pathway that leads to a extremely high and long ramp which leads into "space" if you make it to the top, but then you jump the ramp and careen straight into the ground.
Space Program is a good way to test the speed of vehicles on slopes. Since recent updates, the only cars able to make it to the top of the ramp are the LeDorean, the Banditt, Sweet Justice, and the Squealer.
