Specialty geotechnical drilling contractor, Crux Subsurface, Inc. of Spokane, Washington was acquired Quanta Services (NYSE: PWR), an S&P 500 company and a leader in infrastructure services for the electric power, pipeline and telecommunications industries according to an announcement made in Early April. Crux is well known for their difficult access drilling for geotechnical and environmental projects, but has increasingly gotten into the micropile market, particularly in support of the energy sector.

First Lunar Landing 40 Years Later and Stuck Spirit Rover
[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.
