It turns out there wasn't much to resolve, with no significant issues reported in the countdown, which aborted moments before a mock launch time of 1 p.m. EDT (1700 GMT). The ULA launch team has finished assembling and testing MAVEN's Atlas 5 rocket, and technicians moved the two-stage booster from its Vertical Integration Facility to the launch pad at Complex 41 on Monday. The rocket is missing its payload and nose shroud, which will be added to the Atlas 5 next week. Controllers powered up the Atlas 5 early Tuesday, tested flight and ground systems required for the countdown, and filled the rocket with kerosene and cryogenic propellants. The wet dress rehearsal is a risk reduction exercise for the Atlas 5 and its support team. The test is designed to expose any potential anomalies that could show up on launch day, giving engineers time to fix the problems. With the rehearsal complete, ULA will return the Atlas 5 rocket to the barn to await the arrival of MAVEN, which is finishing up preparations in a clean room at Kennedy Space Center's Payload Hazardous Servicing Facility. Workers pumped fuel into the spacecraft last week, and plans call for MAVEN to be lifted and mated Friday to the adapter that will connect the orbiter to the Atlas 5 rocket's Centaur upper stage. MAVEN will be enclosed inside the rocket's four-meter diameter payload fairing beginning Saturday, with the second half of the clamshell-like aerodynamic shroud to be added Monday. The payload will be trucked to the towering Atlas 5 integration building Nov. 6 to be hoisted and attached to the top of the 189-foot-tall rocket. Launch is on schedule for Nov. 18 in a two-hour window opening at 1:28 p.m. EST (1828 GMT). Received on Tue 29 Oct 2013 03:08:41 PM PDT |
