SPIRIT UPDATE: Spirit Drives to 'Larry's Outcrop' - sol 483-489,
May 20, 2005
Spirit finished work at the target "Reef." Over the weekend (May 14 and
15), Spirit performed work using the instruments on the robotic arm on
a
target informally called, "Davis" on "Jibsheet." Work included use of
the microscopic imager, the rock abrasion tool brush, a long alpha
particle X-ray spectrometer integration, and a long M?ssbauer
spectrometer integration. Spirit spent 2 sols (May 17 and 18) driving
to
"Larry's Outcrop." Upon arrival, Spirit took detailed navigation camera
and panoramic camera observations in support of possible robotic arm
work on Larry's Outcrop. Spirit remains in excellent health.
Total odometry as of May 19, 2005, is 4,368.07 meters (2.71 miles).

OPPORTUNITY UPDATE: Moving Slowly in the Dune - sol 467-470,
May 20, 2005
Opportunity continues to make inch-by-inch progress toward getting out
of the dune where it has been dug-in since sol 446 (April 26).
Sol-by-sol summaries:
Sol 467 (May 17):
Opportunity was commanded to rotate its wheels enough to have rolled 4
meters (13 feet) if there were no slippage. It advanced 2.1 centimeters
(0.8 inch) through the loose material of the dune.
Sol 468:
A commanded motion of 8 meters (26 feet) was executed this sol. Forward
progress was about 4 centimeters (1.6 inches).
Sol 469:
A 2-meter (7-foot) drive was commanded, and Opportunity advanced about
1
centimeter (0.4 inch).
Sol 470 (May 20):
The rover was sent commands for a 12-meter (39-foot) drive. This drive
incorporates larger step sizes, lower current limits for the drive
motors, and a lower bogie angle limit.
