The sensitive spacecraft, the centerpiece of a $453 million mission to probe the Martian atmosphere, will be continuously purged with pure nitrogen to keep the environment inside the container clean. The transport team, comprised of Lockheed Martin, NASA, and University of Colorado officials, says the temperature inside the box is about 70 degrees Fahrenheit with a humidity of less than 30 percent. Those parameters are acceptable for shipment. The box measures about 14 feet tall, 14 feet wide and 7.5 feet long. The spacecraft will take a road trip to Buckley Air Force Base, where a U.S. Air Force C-17 cargo plane waits. Later this morning, technicians will offload the container with MAVEN and place it inside the C-17's cargo hold. Guy Beutelschies, MAVEN's program manager at Lockheed Martin, says the company has shipped more than a half-dozen interplanetary spacecraft from Denver to Florida over the last 15 years. Much of the team has worked most or all of those operations, Beutelschies said. ------------------------------------------ THURSDAY, AUGUST 1, 2013 A NASA spacecraft set to launch to Mars this fall will take a cross-country plane ride Friday in the belly of a U.S. Air Force cargo jet, and we've been invited along for the ride. It's an all-day ordeal, starting early Friday at Lockheed Martin's satellite factory in suburban Denver and ending Friday night at the Kennedy Space Center in Florida, where the Mars orbiter will be placed inside a clean room for final launch preparations. The Mars Atmosphere and Volatile Evolution Mission, or MAVEN, is the first spacecraft to be dispatched to the red planet specifically to study the desert world's thin atmosphere. "We've never sent a spacecraft to Mars just to explore its upper atmosphere," said Bruce Jakosky, MAVEN's chief scientist from the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics. "If you imagine Mars as having had a thicker, warmer atmosphere early in its history, where did the atmosphere ago? Where did the water go?" The job of the $453 million MAVEN mission is to find out, answering one of the most fundamental questions about the red planet: Why did the climate change on Mars? Built by Lockheed Martin, MAVEN will launch from Cape Canaveral, Fla., on Nov. 18 aboard a United Launch Alliance Atlas 5 rocket. If all goes well, the craft will slide into orbit around Mars in September 2014. But before it rockets away to Mars, some logistics are in order - like moving the delicate custom-built spacecraft from Colorado to Florida. An Air Force C-17 cargo plane will do the job, jetting MAVEN from a military base outside Denver to the Shuttle Landing Facility runway at KSC. All along the way, MAVEN will be hooked up to a purge system to keep the satellite and its three sensor packages pristine during the journey. And several dozen Lockheed Martin engineers and technicians will accompany MAVEN on the trip to help load and unload the craft from the C-17 and babysit the orbiter. It takes meticulous planning to pull off such a move in a single day, with every move carefully choreographed well in advance. We'll be there to chronicle the job, offering a look into a rarely-seen part of all space missions. We'll be posting updates here throughout the day Friday and Saturday, when workers will open the crate housing MAVEN inside the KSC clean room. Received on Fri 02 Aug 2013 12:54:43 PM PDT |
