Earning Its 'O'.

The article reports that the Mars Reconnaissance Orbiter (MRO) brings new propulsion design and more redundancy to Mars. MRO is to begin a two-year science mission in November, 2006, followed by two years of relaying data from surface craft that will likely be augmented by more science observations. The spacecraft is well-supplied with propellant. Lockheed Martin Corp. and NASA Jet propulsion Laboratory engineers are readying the Mars Reconnaissance Orbiter for seven months of aerobraking set to start the end of March 2006, after it was captured about the planet on March 10, 2006.
