Getting up to speed, part 2. (Space update)

Legacy NTS atomic test

Halfway into the 21-st Century aughts, I landed a job as a scientist in the Environmental Restoration program at the Nevada Test Site.  This amounted to the study, clean-up, and documentation of contamination left over from the glory days of above-ground nuclear weapon tests.  I wanted fieldwork that other astronaut-hopefuls wouldn’t be getting, and boy did I get it, (in addition to a few fortuitous space-exploration-related surprises.)

First and foremost, learning to deal with, comfortably work around, and analyze radioactivity was a boon.  High-energy radiation from the Sun is one of an astronaut’s primary threats.  Shielding techniques and real-time measurements of dose rates and activity in a remote field environment – You don’t get experience like that in a university.

Secondly, for obvious reasons, getting used to performing scientific and technical work in and around the unique, high-density network of craters left over from testing was also highly advantageous from a planetary science fieldwork perspective.  I’m not the only one to make that connection, either.

As fate would have it, the astronauts who would walk on the Moon on Apollo 14, Apollo 16, and Apollo 17 trained in the same area for the same reasons nearly four decades earlier.

By happy coincidence, I simultaneously had the opportunity to jump into “field” Mars research on the side by being invited to assist the scientist who first discovered dust devils on Mars with fieldwork just outside of Las Vegas.  You see, dust devils seem like no big deal on Earth, but on Mars your average dust devil is a mile wide and eight miles tall.  You can see them from space.  Seriously.  So, using chase trucks and custom-built instrumentation, we chased whirlwinds across dry desert lakebeds to get precious readings from within a dust devil’s core – an area that is not typically easy to access – in order to better understand how dust devils are currently shaping the surface of Mars.

Think the space-geek version of storm chasers.  It was awesome.

Then, in early 2006, I discovered through the course of my work at the Nevada Test Site that NASA and the U.S. Atomic Energy Commission had partnered in a little-known 1960s test program conducted at the site called NERVA.  What they achieved in only a few years is staggering: A series of successful, fully-functional nuclear rocket engines that used liquid hydrogen for fuel, emitted simple hydrogen and water vapor as exhaust, and were nearly twice as powerful as our best chemical rockets today(!).

This will be the subject of a much longer post or posts in the future, but let me just say that the program was not shut down due to safety concerns or failures to successfully produce – NERVA was canceled simply for lack of funds and interest (we stopped going to the Moon and canceled plans for following up to Mars).  My involvement was both exhilarating and heart-breaking, because the reason I became versed in the history and details of the program was to help tear down its last remnants.  Saving knowledge from this program became a sort of personal quest – I find the idea of lost advanced (and superior!) rocket technology sickening – and thus began my side foray into space-era industrial archaeology… but that’s another story.

Work in the environmental program at the test site began to wind down in 2007, and I soon found myself in a new position as a senior hydrogeologist with the Southern Nevada Water Authority – a position I still hold today.  A perfect blend of extremely remote fieldwork combined with intensely analytical science, the job entails measuring every spring and stream and obtaining rainfall measurements across a nearly 1,400-square mile project area and making sense of it meteorologically and geologically.  Why?  We need to determine how much water is in the region in order to lay the foundation for a future 300-mile long freshwater pipeline to supply Las Vegas with much-needed water.  With the program, I’ve covered nearly 100,000 miles of territory (1/3 of the way to the Moon) in the last two years, all of it with a population density of less than 1 person per square mile.  (Might as well have been the Moon in many cases.)  Considering the safety mentality you’re required to develop when you’re really on your own, the logistics of being away from sources of, well, anything, and lots of travel time in cramped quarters with field partners (I calculated it – I saw my field partner more than my wife in 2008) – I look at my time with SNWA as planetary scientist boot camp.

During this time, I also became a part-time Logistics Officer with Nevada’s federal Disaster Medical Assistance Team (DMAT), figuring that emergency response and logistics would also be valuable and unique experience from a future astronaut candidate perspective.  While I haven’t had a deployment since I’ve been on the team roster, I have had plenty of useful training opportunities.  We’ll see.

That essentially brings us up to speed.  With some significant “boots on the ground” experience under my belt, change is in the air.

The game is afoot.
