About 4:25 p.m. EST Friday the $720 million spacecraft will reduce its speed by 2,200 mph, and begin to orbit Mars, The Washington Post reported Monday.
If all goes well -- 21 Mars missions have ended in disaster -- after six months of course and speed corrections, it will settle into a "science orbit" between 199 and 158 miles above the Martian surface, joining three currently operating satellites -- two from NASA and one from the European Space Agency, the Post said.
There it will remain for two years, using inspecting the planet. After that time it will be sent into a higher orbit to become a communications relay satellite.
The Mars Reconnaissance Orbiter has been operating flawlessly since its launch in August. "But we are getting into the dangerous portion of the mission," says Jim Graf of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "A lot can go wrong, and if we don't succeed, we will fly right by the planet."

Moon water discovered: Dampens Moon-formation theory
Using new techniques, scientists have discovered for the first time that tiny beads of volcanic glasses collected from two Apollo missions to the Moon contain water. The researchers found that, contrary to previous thought, water was not entirely vaporized in the violent events that formed the Moon. The new study suggests that the water came from the Moon's interior and was delivered to the surface via volcanic eruptions over 3 billion years ago. The finding calls into question some critical aspects of the "giant impact" theory of the Moon's formation and may have implications for the origin of possible water reservoirs at the Moon's poles. The research is published in the July 10, 2008, issue of
Nature.
