Island, Nunavut, Canada
- Begin extended sun-synchronous navigation experiment
Summary and Progress
- Began extended experiment. This experiment was intended to
system by increasing the distance, exploring rougher terrain,
forcing direct conflicts between sun position and goal location.
plan was to perform a complete circumnavigation of Marine Peak,
prominent feature at the western extreme of Von Braun Planitia,
addition to the previously established circuit of the planitia.
- Experienced communication problems. The experiment started
after 3:00pmCDT, difficulty occurred first with problems establishing
stable communication link with Hyperion and then when the base
generator cut out and disabled communication. The latter was
resolved while the former was a problem through much of the
- Traversed wet, muddy terrain. In the valley to the south of
Peak, Hyperion encountered mud, snowmelt saturated soil. It
these areas without mechanical difficulty at one half nominal
Occasional false positive obstacles were detected by stereo
due to sunlight reflected on pooled water. This necessitated
back from autonomous navigation to safeguarded teleoperation
crossing. The slower speed caused Hyperion to fall behind the
- Experienced more communication problems. In the area east
Peak the radio ethernet antenna and communication bridge failed
maintain a stable link with Hyperion. (Despite a test the previous
day.) The repeater was moved to several locations before a reliable
link was established.
- Foreshadowing tomorrow's report, more difficulties and delays
encountered before Hyperion completed the circuit, on schedule
- Complete extended sun-synchronous navigation experiment
