Log Book for March 16, 2006
EVA Report
Crew 46 Reporting
Start EVA: 1053 hrs
End EVA: 1500 hrs
CDR Zabala-Aliberto: Geologist
Menkes van den Briel: Chief Engineer
Madeline Zabala: Science Officer
Todd Romberger: HSO
Destination Name: Box Canyon
EVA Goals: To familiarize the F.L.A.M.E. crew with the local geology and test out prototype suits for smaller members of the crew. To instruct the HSO and Chief Engineer on the protocols of geological field investigations. To know which samples are important to take back to the MDRS Science Laboratory. To continue training for crew on ATVs for extended periods of time. To search for more concretion-bearing layers beyond the MDRS site.
Results: Soil sampling techniques were stressed on this EVA as well as photogeology and soil sampling. Concretions were also found at/near the Box Canyon Site.
Special Notes: Crew interaction on EVA has improved and communication techniques in the field have been refined.
Lessons Learned: "Geology is a magnificent discipline ... you get to see the outdoors, wear a spacesuit and learn the history of a planet with a simple stroll out of the airlock", V.A. Zabala-Aliberto, CDR, F.L.A.M.E.
EVA-2 Report:
Stacy T. Sklar
Start EVA: 1150 hrs
End EVA: 1400 hrs
Stacy T. Sklar
Angelina Zabala
Gino Zababla
Destination Name: Hab Ridge Gryphaea Fossil Bed
EVA Goals: To further map the Gryphaea fossil bed and to teach the younger crew members how to document paleontological sites.
Results: A .5m square transect of the northeastern part of the Gryphaea fossil bed was completed. Mapping the lateral extant of the fossil bed continued.
Special Notes: Sklar was impressed by the images taken by the younger members of the crew. Many of the images you see on today's photos section are taken by Anglina and Gino.
Lessons Learned: You must mental go over your field equipment list the night before the EVA. This way you can write down the items you may need without forgetting or waiting until the last minute to remember. Always adding to your equipment list at the last minute takes away valuable time in the field.
EVA-3 Report:
Todd Romberger Reporting
Start EVA: 1053 hrs
End EVA: 1500 hrs
CDR Zabala-Aliberto: Geologist
Menkes van den Briel: Chief Engineer
Madeline Zabala: Science Officer
Todd Romberger: HSO
EVA-003: Site #1
Waypoint: 12 S 0518574 / 4252684
Altitude: 1380 m
EVA-003: Site #2
Waypoint: 12 S 0518558 / 4252716
Altitude: 1373 m
EVA-003: Site #3
Waypoint: 12 S 0518566 / 4252694
Altitude: 1375 m
EVA-003: Site #4
Waypoint: 12 S 0519990 / 4256318
Altitude: 1420 m
EVA Goals: To collect samples and take moisture and PH readings at varying sites within ATV range from the Hab and to continue lessons in geology for the HSO and the Chief Engineer.
Results:
EVA-003: Site #1
Waypoint: 12 S 0518574 / 4252684
Altitude: 1380 m
Comments: A seasonal low energy flow regime. Gully walls have evidence of possible Cretaceous worm borrows in overlying layers with lightly oxidized concretions below. Large oxidized outcrops on upper layer. Gully walls composed of clay like material. PH readings varied greatly between two samples taken at the site. Slightly acidic readings taken in a small body of standing water at the base of the gully contrast a very basic reading on the north wall of the gully. The soil composition, solar energy, and endoliths create a chemical regime that is acidic in the body of water. On the north facing wall however, the lack of moisture and low solar energy contribute to a more basic PH level.
EVA-003: Site #2
Waypoint: 12 S 0518558 / 4252716
Altitude: 1373 m
Comments: Dried lakebed near bottom of gully. Soft, clay-like material with small cracks covering the lakebed. The moisture/PH probe encountered resistance at 7 inches deep which indicates higher density material below the surface. Moisture levels increased with depth while PH levels varied from slightly acidic at the surface to more basic at 8 inches depth.
EVA-003: Site #3
Waypoint: 12 S 0518566 / 4252694
Altitude: 1375 m
Comments: Washed out base of gully with small bodies of standing water. Overlying layer indicates possible cretaceous worm borrows mixed with pebble to cobble sized stones. Varying color layers of clay at lower levels.
EVA-003: Site #4
Waypoint: 12 S 0519990 / 4256318
Altitude: 1420 m
Comments: Top of Jurassic-Morrison formation consisting of conglomerates and sandstone with sand dunes at the base which appear to be migrating to the south which indicates an active aeolian regime. Rocks on upper layer are varying in size and heavily oxidized. Area is higher in elevation than immediately surrounding landscape, and rises nearby indicate continuous layers. A nearby rise has a large layer of light sand on the leeward side again indicating an active aeolian regime.
Special Notes: This was an excellent full-sim EVA which included long range ATV use, sample taking and data collecting. Data collected will be plotted and analyzed further. All crew members did a great job!
Lessons Learned: Sometimes ATV's don't start. Be prepared!
