If you thought you saw a UFO on the Vidalia and Natchez highways Tuesday morning, you were almost correct. A test version of NASA’s Orion spacecraft was escorted through the Miss-Lou from White Sands, N.M., to Kennedy Space Center in Florida. The crew module spent the night at the Vidalia Walmart parking lot waiting for an escort to take them across the Mississippi River Tuesday morning. The full-scale test vehicle was used by ground crews in advance of the other tests that took place in New Mexico in 2010. Orion will serve as the vehicle that takes astronauts beyond low-Earth orbit.
