The Mars Phoenix Lander is busy digging even deeper into the arctic ground, trying to find out if the depth it can reach will produce different results from those it has already obtained by digging down about seven inches.
Phoenix, though, is not the only exploration project currently operating on the surface of Mars. Both Mars rovers, Spirit and Opportunity, are still hanging tough. Spirit will remain stationary for a few more months as it builds up its power reserves after a long Martian winter, but is taking panoramic photographs of its surroundings in the meantime. Opportunity, on the other hand, is still literally rolling along. It is beginning its climb out of Victioria Crater, which it has been exploring for about the past Earth year.
Add the probes orbiting Mars, and this is a remarkable time for the fourth planet from the Sun's interaction with humanity.
