Massive Australian Precambrian/Cambrian Impact Structure Massive Australian Precambrian/Cambrian Impact Structure The Massive Australian Precambrian/Cambrian Impact Structure also known as MAPCIS is a proposed impact structure based upon arguments presented by Daniel P. Connelly at Geological Society of America meetings. Its center is located approximately equidistant between Uluru (Ayers Rock) and Mount Conner in Australia's Northern Territory. The structure is approximately in diameter. However, a hypothetical outermost ring in diameter is claimed to be the result of undefined far field stresses. Connelly argues that the age of this hypothetical impact is approximately 545 mya which puts it just before the Cambrian explosion (542 mya) of the
Mission to Mars (attraction) After sponsorship ended, logos referring to the company were removed from the attraction, but the outline of the stylized tail fin in the McDonnell-Douglas logo still remains part of the building's facade as the Redd Rockett's Pizza Port restaurant. The show was designed in cooperation with NASA and was basically a revised and updated version of the previous attraction Flight to the Moon. Guests would now be launched on a spacecraft into space and then approach the surface of the red planet Mars. Guests would first enter a viewing area known as "Mission Control", which was modeled after a typical
