MRO to leave Lockheed Martin in Denver tomorrow. Hopes high for new Mars craft being sent to NASA this week

Jefferson County - Engineer Kevin McNeill compares the Mars Reconnaissance Orbiter to his two children, who recently left home for college.
"You're hopeful everything you've done in 18 years of raising that child has prepared him for life on his own," McNeill said Wednesday, hours before he and his colleagues boxed the school-bus-size craft for shipping.
On Friday, McNeill and the rest of his Lockheed Martin team will send their $500 million baby to Florida. NASA is expected to launch the craft Aug. 10.The unmanned craft will take nearly seven months to reach Mars on a mission that will cost $720 million.
"We're sending up the most capable instrumentation we've ever sent to another planet," said Jim Graf of NASA's Jet Propulsion Laboratory. Previous Mars missions have performed well, he said, but raised more questions than they answered. The Mars Reconnaissance Orbiter, which will return more science data than all past Mars missions combined, should answer many of those questions, he said.
One previous Mars craft captured pictures of what may be gullies running down a crater. The new orbiter will shoot far more detailed photographs of the region, probably nailing down whether wind erosion or water carved the features, Graf said. Because water almost certainly flowed over Mars in the past, the planet is the best place to search for life, said Lockheed scientist Ben Clark.
The new Mars mission may also help solve a 6-year-old mystery: Where is the Mars Polar Lander? That spacecraft, also built by Lockheed, apparently crashed into Mars in 1999 after its landing rockets shut down prematurely. The new orbiter has such sophisticated cameras, it might be able to see evidence of the crash, Graf said.
Lockheed has had mixed success with Mars missions. Mars Odyssey and Mars Global Surveyor were successes, delivering data and images that hinted at a watery past on Mars, for example. But the Polar Lander and Mars Climate Orbiter failed.

I don't know if they are sending MRO by air (which would take a day) or via road convoy (several days).
