?It?s a wonderful morning to go to Mars,? NASA?s Phoenix project manager Barry Goldstein, of the agency?s Jet Propulsion Laboratory (JPL), just before liftoff. As predicted, weather conditions were pristine for the early morning space shot. The launch was delayed 24 hours earlier this week due to bad weather during rocket fueling.

"It was a great launch, so it means we're going to reach a high northern latitude site on Mars and actually sample ice for the first time," Arvidson said. "Now we can get on with the business of doing great science on mars."
Bound for Mars
The $420 million Phoenix mission is built on the ashes of NASA?s canceled Mars Surveyor 2001 Lander and the ill-fated Mars Polar Lander, which crashed during landing in December 1999. Much of the 772-pound (350-kilogram) probe and its seven science instrument packages are built from hardware based on or recycled from those two missions, mission managers have said.
"I started working on this spacecraft in 1997, so it's incredibly gratifying to watch it finally go up," Gasparrini said. "It's not often that you get a second chance in life."

If successful, the landing will mark the first soft touchdown on Mars since NASA?s massive Viking lander missions in the 1970s.

?As smart as we like to think we are, we?re not clearly as smart as we need to be,? Goldstein said before launch, calling Mars a spacecraft eater. ?It really is a difficult job. No matter how many times we land successfully, it will never be routine.?
