Hi all,
The following is a status update on the Pele Rover Mission. The Pele
lunar rover mission concept is a proposal developed by a joint team of
the University of Hawaii, NASA Ames Research Center, NASA Johnson
Space Center, McDonnell Douglas Aerospace, the Lavochkin Association,
and Brown University. The mission concept proposes to explore issues
in lunar science and planetary volcanism that were left unanswered by
Apollo. The Pele team is currently conducting field trials with a
Marsokhod rover in the Kilauea Volcano, Hawaii. A major focus of these
tests is to evaluate the use of advanced teleoperations methods (e.g.,
virtual environment based control, high-fidelity stereo video based
telepresence) for operating the rover from geographically distributed
remote control stations.

Pele Mission Status Report
Hawaii Volcano Observatory -- Kilauea, Hawaii
27-Feb-1995
On the first day of JASON field operations, the Marsokhod is beginning
to show signs of structural wear and tear after three weeks of daily
operations in the rugged environment of the Kilauea volcano. The lava
also impacted operations by forcing the team to re-locate the vehicle
from its initial site before the last scheduled demonstration.
Over the weekend, the on-site team geared up for today's ops by
supporting several JASON rehearsal efforts. These led to the
identification of a stressed cable harness in the vehicle's power
system, which may in part be associated with the higher operating
temperatures that are now being experienced near the lava flows ( at
times exceeding 120 F as the winds come off the active flows that are
only tens of feet away from the vehicle). The situation was nominal
this morning (5 a.m. HI time) until a bracket connecting the rear axle
to the chassis failed, rendering the vehicle essentially immobile.
Student operators at the designated PIN sites in later demos were able
to control the pan-tilt camera assembly and the manipulator arm.
A repair for the bracket piece is now under way at a local machine
shop in Hilo and the plan is to get the rover back into full operation
by tomorrow (Tuesday). A key consideration will be the selection of a
demonstration site that is both educationally challenging and not
excessively hard on the rover, given that there are still eleven full
days of operations to go. Such a selection in turn will have to be
continually monitored to minimize threats to operations and the
vehicle itself as the lava flows shift over time.
