Ron and List,
Does it appear to you that there may have been some shearing on the =
right hand side of the rock called 'Adirondack'?

        Spirit Drives to a Rock Called 'Adirondack' for Close Inspection
=09
        NASA's Spirit rover has successfully driven to its first target on
        Mars, a football-sized rock that scientists have dubbed Adirondack.
=09
        The Mars Exploration Rover flight team at NASA's Jet Propulsion
        Laboratory, Pasadena, Calif., plans to send commands to Spirit early
        Tuesday to examine Adirondack with a microscope and two instruments
        that reveal the composition of rocks, said JPL's Dr. Mark Adler,
        Spirit mission manager. The instruments are the M=F6ssbauer=20
        spectrometer and the alpha particle X-ray spectrometer.
=09
        Spirit successfully rolled off the lander and onto the martian
        surface last Thursday. To make the drive to Adirondack, the rover
        turned 40 degrees in short arcs totaling 95 centimeters (3.1 feet).
        It then turned in place to face the target rock and drove four short
        moves straightforward totaling 1.9 meters (6.2 feet). The moves
        covered a span of 30 minutes on Sunday, though most of that was
        sitting still and taking pictures between moves. The total amount
        of time when Spirit was actually moving was about two minutes.
=09
        "These are the sorts of baby steps we're taking," said JPL's Dr.
        Eddie Tunstel, rover mobility engineer.
=09
        "The drive was designed for two purposes, one of which was to get to
        the rock," Tunstel said. "From the mobility engineers' standpoint,
        this drive was geared to testing out how we do drives on this new
        surface." Gathering new information such as how much the wheels
        slip in the martian soil will give the team confidence for more
        ambitious drives in future weeks and months.
=09
        "Adirondack is now about one foot (30 centimeters) in front of the
        front wheels," he said.
=09
        Scientists chose Adirondack to be Spirit's first target rock rather
        than another rock, called Sashimi, that would have been a shorter,
        straight-ahead drive. Rocks are time capsules containing evidence of
        the environmental conditions of the past, said Dr. Dave Des Marais,
        a rover science-team member from NASA Ames Research Center, Moffett
        Field, Calif. "We needed to decide which of these time capsules to
        open."
=09
        Sashimi appears dustier than Adirondack. The dust layer could
        obscure good observations of the rock's surface, which may give
        information about chemical changes and other weathering from
        environmental conditions affecting the rock since its surface was
        fresh. Also, Sashimi is more pitted than Adirondack. That makes it a
        poorer candidate for the rover's rock abrasion tool, which scrapes
        away a rock's surface for a view of the interior evidence about
        environmental conditions when the rock first formed. Adirondack has
        a "nice, flat surface" well suited to trying out the rover's tools
        on their first martian rock, Des Marais said.
=09
        "The hypothesis is that this is a volcanic rock, but we'll test that
        hypothesis," he said.=20
=09
        Spirit arrived at Mars Jan. 3 (EST and PST; Jan.
        4 Universal Time) after a seven-month journey. In coming weeks and =
months,
        according to plans, it will be exploring for clues in rocks and
        soil to decipher whether the past environment in Gusev Crater
        was ever watery and possibly suitable to sustain life.
=09
        Spirit's twin Mars Exploration Rover, Opportunity, will reach Mars
        on Jan. 25 (EST and Universal Time; 9:05 p.m., Jan. 24, PST) to
        begin a similar examination of a site on the opposite side of the
        planet from Gusev Crater.
