<p>Since Andrew's notes got eaten I will post my Scribblenotes of yesterdays teleconference. Some of this has been discussed already</p><p>Peter Smith, PI, Ray Arbidson Co Investigator Robotic Arm from WUSTL, Pat Woids Sr Engineer Phoenix</p><p>PS: I was worried 5 years ago about not having wheels, but it's a thrill we're at a great location to do the science we came for. Polygons are a clue there's ice. "Holy Cow" (bright material beneath lander) is a flat bright surface, sure looks like ice. (Question asked later can you scoop it- answer is no; arm cannot access that area)</p><p>We've had first interactions. "Yeti" was a press down into the soil by the scoop.</p><p>Later a dig and dump to the left of National Park. Trench dug, material scooped and examined by arm camera, showing white material that could be ice, or Kiesterite, MgSO4-H20 (rare on earth)- Evaporate.</p><p>TEGA Filament problem----. Switched to backup filament, worked fine. In response to a question, is first filament dead? Maybe not. It presented as an intermittent problem during 0G, now is hard short. Possibly a contaminant particle. If needed they can try and shake it loose, a nearby solenoid can be used to vibrate it. Prefer not to do that, but if needed we can try) Filament is used to ionize gas from heated material so it can be magnetically transported to the mass spectrometer.</p><p>First dig was above Yeti, first samples (that will now go to TEGA as originally planned) will be Baby Bear, Mama Bear and Papa Bear to right of Yeti. (Ray gets to name them as he and Peter exchanged glances, Peter said hey, it's his scoop, he gets to name them.) 3 Adjacent samples one each to each of the 3 analysis instruments. Looks like that will be Sol 9 or 10 so next day or two. Full TEGA analysis takes 4 or 5 days. First it's heated to ~ 100C to melt and evaporate any ice. Then next heating is to 1000C to drive out even the most recalictrant materials from the soil. Last is reheat to 1000C as a baseline after all material has been heated once.</p><p>First dig materials were dumped in an inaccessable area to left from height of ~ 50 CM.</p><p>Questions about Yeti. Why does it look like that? Scoop pressed down into sloped surface. So it wasn't intentional? A: No. Q? So no conspiracies then? No, "We don't have time for conpiracies"
PS</p><p>3D images will be done of Holy Cow, as well as images during different lighting conditions. Probably too far away for LED's to allow color images; besides the sun never goes down, so unless you are close, color images are too hard.</p><p>Pitting on Holy Cow? Maybe some, unclear whether from melting or pebbles being dislodged. Thrusters likely didn't melt much since contact was so brief (Remember Phoenix was falling at ~ 2.5 meters per second-MW)</p><p>Soil is pretty much what expected, loose soil and some "duracrust or Duricrust" cementing the surface together. Seems pretty cohesive, preserves slopes when scooped.</p><p>Response to "Too Much Salt for Life" Harvard paper? No, too busy to read papers and respond.</p><p>20C difference between your head an feet (head is colder) During night, stable layers, during day lots of convective mixing. Makes Temp reading noisy as parcels of air pass by at different temps.</p><p> </p><p>-------------------------</p><p>That's about it for me, I'mm be back to correct speeling, grammer, etc shortley. Trying to find where today's teleconference can be heard.</p><p> </p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
