Spacecraft Draw Closer to MarsPublication: National Geographic News Date: December 12, 2003 View Article
Spacecraft from three different space missions are drawing closer to Mars. Over the next six weeks, landers and rovers are scheduled to touch down on the red planet’s surface. Together with orbiting spacecraft, the probes will poke, scratch, sniff, and image the Martian environment for clues to the existence of past or present life.
Mission scientists will clear a significant hurdle to see their spacecraft simply reach Mars.
