We continue to hear good things about the construction economy. In a new article in our sister publication, Machine Control Magazine, Marco Cecala mentions this, and although the article mostly pertains to buying used equipment, the opening paragraph still represents a positive indication about construction activity.
In particular, the Oil Patch is positively booming, with surveying jobs available from Texas to Alberta. And this in spite of the administration's blockage of the Keystone Pipeline. Years ago, I learned that there's still plenty of recoverable oil in our country, it just depends on the per barrel price. That is, when the price is high enough, the exploration begins.
As evidence of this, because of the success of shale gas exploration, the price of natural gas is less than half what it was in 2008. Reacting to the law of supply and demand, one of the major gas companies, Chesapeake Energy, recently called a halt to some of its activities. And now we're hearing that it's not only gas they're finding in the shale, but oil as well, so maybe our energy future isn't so bleak after all.
As always, please don't hesitate to contact me if you've got a project or story you'd like to share. Thanks for your support.
Until next time,

feature If you're like me, perhaps one of the things you like about surveying is the opportunity to be precise and accurate. Whenever we make a measurement, we strive to make it to the best of our ability. The vast majority of us will never be able to participate in ultra-precise work, but we still like reading about it.

Several years ago, NASA launched the Gravity Recovery and Climate Experiment (GRACE). This fascinating endeavor involved twin washing-machine-sized satellites chasing each other in orbit. As they travel in orbit, gravity effects from the Earth causes the lead satellite to speed up or slow down, and ultra-precise tracking between the two detects this relative movement.

The spinoff for us has been that this detection of global gravity has allowed researchers to refine geoid models, and indeed, when I inquired to one of the NGS gravity experts, Dr. Dan Roman, and asked, "Has the GRACE mission data been useful to NGS in its geoid determinations?", he said, "Very useful. It underlies all our models and will be the basis for determining a global datum."

Last year, NASA launched another gravity experiment, this time to the Moon. The experiment will allow us to determine the make-up of the Moon's inner core. Dubbed GRAIL (Gravity Recovery and Interior Laboratory), it is basically identical to GRACE. But here's the cool measurement part: Even though the two spacecraft will range between 40 and 140 miles apart, the Ka-band radar NASA is using to make the measurements can resolve the distance between them to less that the size of a red blood cell, or a few tenths of a micron per second in their relative velocities.

The image above, courtesy of NASA/JPL-Caltech, shows an artist's conception of the GRAIL satellites in orbit around the Moon. And as a side note, the Ka-band radar is the same radar the police use in their speed guns. Except for the earliest units in the fifties, X-band (10.525 Gigahertz) was the only frequency used for police radar until the mid-1970s. K-band was developed for police use in 1976 and currently over 60% of all the police radar guns use this frequency. Ka-band is the latest generation. I don't know if it has to do with Ka-band, but it wasn't until I stopped using a radar detector that I stopped getting speeding tickets!
