Each day, Spirit logs a reduction in the total amount of solar energy collected as the sun sinks lower on the planet's northern horizon.

    The science team's objective is to do as much science as possible while concentrating on a drive campaign that will move the rover to the north-facing slopes of "McCool Hill." The team has already begun mapping routes to McCool, where Spirit will attempt to survive a second Martian winter with its solar panels tilted toward the sun." <p> <b>Opportunity Status: Opportunity Continues to Skirt Erebus Crater</b> - <i>sol 735-743, Feb 24, 2006</i> <p> "After completing work at the outcrop called "Olympia," Opportunity proceeded around the western edge of "Erebus Crater" toward an outcrop dubbed "Payson." After performing diagnostic tests on Martian day, or sol, 735 (Feb. 17, 2006), the rover team decided to increase rotor resistance from 65 ohms to 80 ohms for stowing and unstowing the robotic arm. Opportunity successfully stowed and unstowed the arm on both sols 740 and 741. As long as the robotic arm remains in calibration, the higher resistance value provides no additional risk." <p> <a href="http://marsoweb.nas.nasa.gov/landingsites/">Landing sites</a> <p> Visit the <a href="http://marsrovers.jpl.nasa.gov/home/index.html">Mars Exploration Rover<a/> page. </font></td> </tr> <tr> <td valign=top align=center width=15%><img src="http://home.att.net/~bfa3/Graphics/mro-space.jpg"></td> <td><font size=+1><b><font size=+2>M</font>ars Reconnaissance Orbiter</b> - February 24, 2006 - NASA's Next Leap in Mars Exploration Nears Arrival</b> <p> "As it nears Mars on March 10, a NASA spacecraft designed to examine the red planet in unprecedented detail from low orbit will point its main thrusters forward, then fire them to slow itself enough for Mars' gravity to grab it into orbit.
