NASA is moving ahead with plans to put a long-armed lander on Mars’ icy north pole to search for cluesfor water and possible signs of life.
The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samplesto analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.
Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbesexisted in the ice.
Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.
True to its name, Phoenix rose from the ashes of previousmissions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction.
The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.

Microsoft founder Bill Gates said that he planned to give away almost all of his vast fortune, largely to the cause of global health, during the course of his lifetime. With an estimatedworth of more than $ 40 billion, according to Forbes, the project will be no small featfor Gates. Having already provided the Bill & Melinda Gates Foundation with $ 24 billion to address global health issues, Gates said that eventually his entire fortune will be put towards the cause except “a few percent left for the kids.”
So what has made the richest man in the world to channel his resources so heavily into one interest? Gates believes that “the equality of opportunity” in which Americans take such pride needs to extend to other nations around the world. Improving the health of the populations, he says, has proven to be an essential method in helping poor countries to be financially successful. “National borders allow inequalities,” said Gates, “We all need to take a more global view, rather than just saying my country is doing well. We have to step up these health issues, knowing how few resources are going into them.”
Gates said that both his parents set good examples to him as a child. His father, William H. Gates, was the head of the local Planned Parenthood, and his mother, Mary, volunteered for the United Way. As he gathered his fortune, Gates knew he would eventually want to give back as well, but he didn’t expect to devote himself whole-heartedly to one project until he was about 60.
However, Gates, 47, began to question his ability to wait that long. “It seemed there was a real time urgency,” Gates said, “I started to think, how many lives could I save before then?”
