Endless Summer? |
 |
Both Mars Exploration Rovers are fighters, beating the count a handful of times on Earth and on Mars. Having flown in the face of "old age" and impending demise, Spirit and Opportunity might also be able to resist the reduction of direct sunlight and Mother Nature?s minions of martian winter clouds.

About Face: Rover Engineers Change the Rules for Driving |
 |
With Spirit?s right front wheel showing signs of age, engineers are finding creative ways to keep the rover moving. They?re inventing a whole new rule book, such as driving forward in reverse and turning the wheels to go straight.

Spacecraft Will Examine Mars in Greater Detail than Ever Before |
 |
| The Mars Reconnaissance Orbiter is a little over a year away from its date with destiny, when it will ride atop a rocket into space, bound for the Red Planet. After arriving at Mars, the orbiter will "follow the water" like other NASA missions to Mars, spending several years collecting a treasure trove of data about martian geology, mineralogy, and climate. This is the first of three articles about the Mars Reconnaissance Orbiter. Stay tuned for the other two.

 |
| Less than two weeks after Spirit landed on Mars, rover engineers and scientists were already planning
Spirit's itinerary on the surface. "Go To That Crater And Turn Right" read the headline of a
January 13 press release. Needless to say, generically referring to features as "that crater," "this rock," or "these hills" could quickly
become confusing.

The Odyssey of Odyssey's 10,000 Orbits |
 |
| Like a sweet, older sibling standing quietly to the side as the baby of the family gets all
the "ooh's" and "aah's," the 2001 Mars Odyssey orbiter has blended into the background noise
of cheers for the Mars Exploration Rover discoveries. But Odyssey deserves her own praise and
applause this Saturday as she reaches a major milestone.

How Did Navigators Hit Their Precise Landing Target on Mars? |
 |
| To land in a precise location on Mars after traveling over 300 million miles, navigators at the Jet Propulsion Laboratory (JPL) had to overcome the head-spinning challenges of calculating the exact speeds of a rotating Earth, a rotating Mars, and a rotating spacecraft, while they all simultaneously are spinning in their own radical orbits around the Sun.
