First Lunar Landing 40 Years Later and Stuck Spirit Rover

Astronaut Edwin E. Aldrin near a leg of the Lunar Module [Editor] For crying out loud. Two weeks later, and I finally notice the title of my post was 20 years off! Its the 40th anniversary, not the 20th. Sheesh! [/Editor] It’s hard to believe that such a tremendously historic scientific and cultural event is celebrating its 20th Anniversary this month! On July 20, 1969, Apollo 11 astronauts “Buzz” Aldrin and Neil Armstrong became the first humans to set foot on the Moon. [Astronaut Edwin E. Aldrin near a leg of the Lunar Module.

One of the first featured articles I published on GeoPrac was a remarkable narrative by my NCS Consultants, LLC colleague, Dr. Ed Nowatzki, sharing his recollections of his work on the geotechnical (soils engineering)aspects of the design of the first lunar lander or LM. I was doubly reminded of his article recently, first because of the milestone anniversary, but also because a different spacecraft was having some soil-related trouble on the Planet Mars.

ASTM Updates June 2009

American Society of Testing Materials Logo - ASTMD5434 – “Standard Guide for Field Logging of Subsurface Explorations of Soil and Rock” and D4429 – “Standard Test Method for CBR (California Bearing Ratio) of Soils in Place” are two standards revised this month that may be of interest to geotechnical engineers. Those in the construction services and materials testing business should take a look at a number of changes to relevant standards. This month there are also a few revised standards related to detection of different ions in water. I also see that there are a number of geothermal and solar standards that were reapproved this month, most of them seem to have been last modified in the late 1980’s and early 1990’s. Click through for the full list of new, revised and reapproved ASTM standards from June.

Trimble Yuma Field Tablet PC has Pricing Info

Trimble Yuma ruggedized tablet PC

I introduced this ruggedized field tablet PC by Trimble here back in March, but there wasn’t any pricing information available at that time. To refresh, it has a military grade ruggedized design to keep out dirt and water, 32GB solid state drive (no moving parts), built in GPS, Wi-Fi, bluetooth 2.0, 2 integrated digital cameras with geotagging functionality (why 2?), Windows Vista Business, and a 7″ sunlight readable screen all in a 2.6-lb package. Read on for the $$.
