MER-B Science Planning Sols 1820-1821: Friday, March 6: 8:00 PST
Science Kick-Off/SOWG:
We had an excellent drive and have received data from both ODY and MRO. Rover
Planners reported that we drove 40 meters to the southwest, are on hard soil and there are
no concerns. For today’s drive, we will head south and stop near a small crater we are
calling "Resolution." The second sol will be remote sensing.
From the TDL report using sol 1816 data from two UHF passes: 497 Whrs on the arrays;
505 Whr predict; 2575 data products in flash; 1008 mbits available; 151 mbit delete.
The TUL said we could do an 80 meter drive (backwards) today -- possibly do a QFA,
but it will take time out of the drive. She decided to put a QFA in the plan, but will
remove it downstairs if needed.
The sol 1819 pass will not come down in time for Friday planning, so we have to be
careful with priorities as our critical exceeds the first sol’s 52 mbit downlink.
Rob Sullivan suggested we take a look at a dark patch that is northeast of our current
location. He asked for a 4x1 Pancam at L1 without a caltarget, but not if it is going to
take time out of the drive. The Chair said color would help distinguish the materials in
that area. The L1 was changed to an L257. Rob also suggested we bump up the rearward
Navcam to 3bpp since we have the bits.
Tim Parker suggested imaging a patch of cobbles seen in a HiRISE image which might
be outcrop fragments from a buried impact crater. It is to the east of us located 22.5
meters from our present position. The Chair said we should add this to the plan as a 3
filter single frame.
LTP Report:
We had an approximately 40 meter drive on sol 1816 and will continue driving from this
point farther south. There are some ripples to cross and some outcrop to go by. The dark
object in the post-drive imaging might be the rim of a crater – a possible target for a
drive-by shooting. There are a couple cobbles in the field of view of the foreground
survey, but mostly typical Meridiani surface. We will concentrate on driving in the sols
ahead. We will plan two sols on Friday and return to nominal planning on Monday. Per
the TUL, we will start using MRO on Monday and will not be relying on ODY for the
next three planning sols. We are in good shape in flash. The recommendation is 160
mbits, but we can go higher.
Long Term Liens:
-MI Sky Flats (after 15:00 LST – 2 lossless images, ~10 mbits total)
-Seismology Observation (last done sol 1809)
-Cobbles (IDD, Pancam 13F loco 1/16 subframe)
-IDD (APXS) typical (spherule-poor) soil
-IDD fine soil (thick dust deposit)
-MTES dust mitigation
-Bedrock pavement (IDD, multi-filter Pancam)
-Atmospheric observations, including Ar
-Pancam albedo pan (last done sol 1798)
PDL Reports:
PC: Healthy; all products down including the 4x1 drive direction mosaic and full
resolution frames from the sol 1814 foreground survey.
MT: No new data.

APAM (11:00)
Before APAM, priorities for the Navcam 5x1 were center frames at 22, wings at 29 taken
left to right, then the four Pancams at 26 left to right. Later, the Chair notified the ECAM
PUL the left three Navcams should come down before the right two. Priorities are now
22,22,22,29,29.
Before APAM, The Pancam PUL notified the Chair that the total time for the pre-drive
Pancams with color added is 14.2 minutes.
The RPs said that today we will head south to set up for a drive-by shooting of the crater
“Resolution” on Friday. The rover will travel 20 meters and then turn due south and
proceed another 60 meters. The Chair said “Resolution” is a “fresh” crater that might be
part of a crater cluster.
At the end of APAM, there was an extensive discussion about the elevated currents on
the right front wheel. RPs said we saw an improvement when we took a week off. We
have not seen an improvement now that we are driving every day, so there is interest to
do a prolonged rest. If we do not drive Friday, we would have three sols of rest, then
drive on Monday and check the currents to see if that strategy made any difference. The
remainder of the discussion was offline.

Master Submaster Walkthrough (14:15)
Before Master Submaster, the PI spoke with the Chair about the issue of the right front
wheel. He also consulted with Jake Matijevic offline.
The drive will be 80 meters of blind driving with 3 slip checks.
After Master Submaster, RPs raised the issue of something in the sol 1816 downlink rear
hazcams (right eye) that looks like a loose cable tie. Matt H. went to the testbed and
found it to be a piece of material held in place with lacing cord. It looks like the lacing
cord frayed open and he feels it is not a concern.
