Having an unashamedly good time stealing a few moments between talks inside the XCor Lynx spacecraft mockup parked behind NSRC 2013.

I recently had the great pleasure to give a talk (and serve as co-author for a second) at the fourth annual Next Generation Suborbital Researchers Conference (NSRC), held this year in Boulder, Colorado.

As a one-of-a-kind collection of researchers, entrepreneurs, spacecraft providers, students, and government representatives, NSRC’s intent is to foster collaboration of a sort that will enable the research world to fully utilize what amount to a fleet of new spacecraft looking to come online within the next 24 months.  In all, exciting to be amongst like-minded folks, great to see familiar faces again, and a thrill to forge new alliances.

Two Radiation Take-Homes for the Suborbital Space Community

IMG_4535So, what was I doing there?  In brief, on behalf of my spaceflight consulting firm, Astrowright, I made a daring and ill-advised attempt to shove a 40-slide presentation into 10 minutes, with (based on positive feedback) it seems at least a small amount of success.  (I wouldn’t have even made such a blitzkrieg attempt unless it was absolutely necessary in the context of my talk.)

The intent?  To give a broad enough overview of radiation detector theory so that I had a prayer of communicating to this very select audience two imminent realities of space radiation dosimetry:

  1. The private/commercial spaceflight world, particularly in the suborbital context, is primed to (mis)use off-the-shelf radiation dosimeters designed for the commercial nuclear world; these instruments will not deliver complete or ultimately meaningful numbers without applying specific scaling algorithms to the results, in essence calibrating them for the space environment.  User beware!
  2. The greatest benefit of bothering to outfit suborbital astronauts with radiation dosimeters might not be to the spaceflight participants themselves, (who would receive in all but the most extraordinary circumstances a practically immeasurable radiation dose).  Instead, the greatest effect may be to improve Earth-based low-dose modeling and safety standards, the researchers engaged in which would benefit immeasurably from having a completely new population group to study who are intentionally exposing themselves to low-dose, high-intensity radiation.  This is also, *hint hint*, a completely untapped research funding angle (contact me if interested in collaborating – seriously!).

So, there you have it.  If not taking advantage of my own firm’s radiation dosimetry services, my message to the suborbital spaceflight world was to at least engage in planning one’s own flight experience armed to understand that accurate dosimetry in the space environment is not something one can just pull off a shelf and slap on the outside of a pressure suit!

Space Training Roadmap

The second talk, which was expertly given by co-conspirator Dr. Mindy Howard of Inner Space Training, involved a task-based assessment of potential spaceflight tasks for suborbital spaceflight participant.  The objective there?  The development of a spaceflight training “roadmap” to help participants decide which training amongst the many types offered by providers is relevant and necessary for their personal flight goals.

The power to decide which training is or is not relevant to an individual should not, in my opinion, be left up to the spacecraft providers (who may and likely will not have your specific goals in mind)!  That’s where our roadmap research comes in.

Please feel free to contact me or Dr. Howard for any additional details along those lines.

Lingering Thoughts

Well, the pulse at the conference was that the next twelve months appear to be crucial.  With business plans starting to kick in and metal finally being flight tested, I feel as though there are two distinct options for NSRC 2014: It will either be aflood with the excitement borne of the dawn of commercial suborbital spaceflight, or attendance will plummet as cynicism and a fear of perpetual development cycles sets in.

For now, the future looks bright, and that’s good news!

Until next time, NSRC.  Cheers!

A shotgun blast of suborbital science

15 03 2012

I’m pleased to report that I recently had the fortune to represent my spaceflight consulting firm Astrowright as a sponsor of, as well as present research at, the Next-Generation Suborbital Researcher’s Conference this past February 26-29 in Palo Alto, CA.  

Ashley presenting our voluntary "Flight Readiness" certification service at NSRC 2012!

Specifically, after nearly a year of research and client-training-data-mining together with my friend/ballet-dancer/anthropologist/excercise-scientist/astronaut-trainer/partner-in-crime Ashley Boron, our presentations centered this year on our frontier fitness services – Astrowright’s custom preflight fitness training program for space passengers-to-be and a “flight readiness” benchmark testing and certification program intended to help aspiring spaceflight pros demonstrate that they’ve got the Right Stuff

The three-day event was intense – with a flurry of presentations covering everything from spacecraft development and mental stress training to planetary science and research payload design.  If that weren’t enough, beyond the research presented at the conference, (for the interested, the program is available here,) the meeting was an explosion of exciting commercial spaceflight activity, from keynote speaker Neil Armstrong’s comparison of early X-15 flights to the current activity in civilian spacecraft testing to XCOR’s giveaway of a trip to space!

Unfortunately, I had only a single day to fly out there and fly back – one of the pitfalls of too many irons in the fire – but the experience in even that short amount of time, like the last one, was thrilling.  The conference smashed both attendance and support records, as well – Further evidence that the suborbital science community is nothing shy of a force of nature blasting the doors off the hinges of civilian spaceflight.

Like many of us have been championing for a while now, a paradigm shift truly feels in-progress.  Many networking and potential research and business opportunities arose as a result of NSRC 2012… and I can’t wait to tell everyone about them at NSRC 2013!

Semper exploro!





Solar System’s “Planet X” lost in space?

21 10 2011

Well, the intriguing possibilities affecting the likelihood of a mysterious companion in our Solar System continue to blossom.

First, the actions of comets suggested that there may be a large “Planet X” named Tyche beyond the Oort Cloud.  Then, we discovered planets around distant stars with highly elliptical, highly inclined orbits, giving us more potential places (oblique orbits) to look for distant, cool companions in our own system.

Now, SwRI researcher David Nesvorny recently published research indicating that our Solar System likely did have another giant planet in its youth that was flung into space as the planets matured and settled into their current orbits.

Why?  Well, as it turns out, computer modeling of star systems with only four giant planets, (read: Jupiter, Saturn, Uranus, and Neptune,) doesn’t tend to settle into a Solar System that looks anything like our own.  However, adding a fifth, giant icy world into the primordial mix appears to generate systems like ours, though this Planet X is ejected into interstellar space in the process.

So, according to this new research, there may indeed have been a Planet X in our planetary past, though not one that could ever return to fulfill doomsday prophesies.

Might the cold, shadowy deep beyond the prying eyes of our best infrared telescopes conceal large worlds awaiting the heady thrill of human exploration?  Research continues to tease us with the possibility.

I for one believe our star system has big surprises yet in store.  Time will tell.





Future SwRI astronauts stomp on the accelerator

A quick note today on the further development of the worlds’ first commercial scientist-astronauts!  The Southwest Research Institute‘s (SwRI) suborbital research program, after its stunning announcement last spring of the purchase of several research seats on upcoming suborbital spaceflights, is showing no signs of slowing.

Recently, after their three commercial scientist-astronauts-in-training, (specifically termed payload specialists,) completed basic astronaut training, they announced the release of their project mission patch (at left).

I’m not sure if anyone else feels the same way, but I’ll be brave enough to admit that something as technically irrelevant as a patch can make an endeavor feel suddenly very real.

According to their recent statements, the team is moving out of the phase of training and the construction of their spaceflight experiments to fine-tuning their payloads and integrating them with future spacecraft.  With SwRI and Dr. Alan Stern leading the way, the advent of commercial civilian scientist-astronauts is upon us, and I couldn’t be more thrilled.  I hope to follow right behind.

Ad astra, SwRI!





T-minus 1 week: Aiming for NASTAR

I’m coming up on a positively Everest-ian milestone in my ongoing quest to become a commercial astronaut, and it’s been a long time coming:  Astronaut training.

Supported by my spaceflight consulting firm, Astrowright Spaceflight Consulting LLC, I’m heading out in a week to attend highly specialized training offered by the only FAA-certified civilian spaceflight training outfit around.

The location?  Philadelphia, PA, at the National AeroSpace Training and Research (NASTAR) Center.

Among the NASTAR Center’s many aerospace services, not only do they provide generalized spaceflight training for the many civilian tourist “spaceflight participants” who are planning sub-orbital jaunts in the next couple of years, (e.g., on Virgin Galactic’s spacecraft,) but they also offer specific sub-orbital scientist training designed to prepare researchers to withstand the forces and avoid the distractions of spaceflight so that they can do what they’ve been wanting to do for (at least in my case) an entire career:

Perform quality science off-world.

For a taste of what the training is like, (which was developed in part by SwRI and NSRC civilian scientist-astronaut forerunner Dr. Alan Stern,) check out this excellent article written by Space.com contributor Clara Moskowitz, where she chronicles her experiences attending the program last October.

In addition to more traditional classroom instruction, the program involves thrilling (to me, anyway) “right stuff” rigors, such as oxygen deprivation training, high g-force (centrifuge) simulations of spacecraft launch and re-entry, and an array of supplemental components.

Needless to say, this training will help to round out our firm’s technical expertise so that we can begin offering expanded service beyond our current pre-flight fitness training and radiation dosimetry services into full-fledged (atmospheric) microgravity and sub-orbital payload specialist territory.

Many thanks to the family and friends that have helped me to get to this point, and it goes without saying that I’ll be blogging like a maniac as I head through the program.  Expect more on this in about a week.

T-minus 168 hours and counting…





Chasing Mars through Eldorado Valley

28 06 2010

This past Friday I was fortunate enough to reunite with my friend Dr. Steve Metzger of the Planetary Science Institute (PSI) to participate in another field season of dust-devil-chasing with a platoon of Mars researchers.  The crew this year included Dr. Asmin Pathare of PSI,  Dr. Lori Fenton of the SETI Institute, Tim Michaels of the Southwest Research Institute, graduate students from the University of Michigan, and a bevy of others from institutions both local and abroad.

As always, it was blisteringly hot and completely awesome.

The objective?  Characterize meteorological conditions and geomorphological events here, (particularly dust devils,) so that we might better understand them on Mars.

Despite how insignificant dust seems, the way that dust is moved in a planetary atmosphere affects most everything, from cloud formation, global warming, and weather patterns to the raw density of the air.  And, aside from the more intellectually-lofty goals of understanding the history of Mars and understanding climate here on Earth, NASA really cares about the density of the Martian atmosphere simply because we need to know that to calculate how to land things there.

The location, Eldorado Valley, is a vesicularbasalt-ridden desert playa between Las Vegas and Boulder City, Nevada that just happens to be a spitting analog for several aspects of the Martian surface.

Fortuitously, it also just happens to be in my neighborhood.

In the arsenal of instrumentation today were several different equipment packages and setups, from massive meteorological towers to smaller future Mars-lander instrument stations, and from sensor-laden “storm chaser” trucks and remote operated mini-trucks to observation waypoints complete with various types of recording equipment.  Believe you me, the science was out in force.

I partnered up with Steve in the chase truck, running as data-logging copilot for a portion of the day as we barreled across the playa, jumping on leads from the spotters and chasing down dust devils in a mad attempt to swing in front of them, thereby getting a clean slice of data through the vortex interiors with the sensors on the outside of the truck.

Despite it being windy enough to threaten blowing dust devils apart, we managed to nail quite a few by the end of the day, soaking up gobs of data on pressure, temperature, and the sediment content of the air.

I even had the chance to fire off one of the military-grade smoke grenades I brought along (to see if they actually work) in preparation for a future trip I’ve been planning.  While I didn’t get this one into a dust devil, the plan is to try and lob a grenade right in front of an approaching devil and record video of the inflow patterns across the leading edge of the vortex.  In my book it never hurts to test mathematical models with some real-world experiments.

In any event, it was a thrill and quite a privilege to jump into this, my third time out with Dr. Metzger in five years.  The team will be out in the field all of this next week, and with any luck I might end up back out with them next Friday.

Is it Mars?  Not quite.  But it is definitely close enough to whet the appetite.





Dawn of the Corporate Scientist-Astronaut

14 05 2010

For those of you who have known me a while, who have had to endure my many rants during the last decade-and-a-half about the future and the promise of corporate space exploration, I have four words:

I told you so.

It’s with an almost electric sense of expectation that I am pleased to report a change in the tide of space exploration.  It’s a change that history has never seen before.  -With the advent of private spacecraft, (e.g., Virgin Galactic, SpaceX, Orbital Sciences, XCOR Aerospace, Armadillo Aerospace,) a critical mass must be near or already achieved, because suddenly the Corporate Scientist-Astronaut has taken shape.  Companies are stepping up to provide training, and pioneers are filling out the flight suits I hope to one day wear.  It’s thrilling.

For example, the Federal Aviation Administration’s Office of Commercial Space Transportation has recently awarded safety approval to a private firm to offer astronaut training – known as the National AeroSpace Training and Research (NASTAR) Center, it’s the first of its kind.  Their services include centrifuges, hyperbaric chambers, technical training, and custom flight simulators, and they’re state-of-the-art.

Then, there’s Starfighters, Inc. – the first company of its kind to get both the FAA and NASA’s approval to provide live suborbital training to corporate astronaut-hopefuls using a small fleet of F-104 Starfigher jet aircraft.

Meanwhile, the Southwest Research Institute (SwRI), a non-profit applied research and development organization, has started taking advantage of these training opportunities for its own scientists to prepare for the new corporate space opportunities as they arise.  Dr. Daniel Durda, one of the first SwRI scientists to participate, says, “We’re finally arriving at the day when space scientists can conduct their research ‘in the field’ in the same way that botanists, geologists and oceanographers have been doing all along. We hope many of our fellow researchers and educators in the diverse disciplines that will benefit from frequent access to space will also get in line to fly.”

And, then there’s the Astronauts4Hire initiative – with a collection of young up-and-coming space scientists vying to get their training at the aforementioned facilities sponsored so that they too can “get in line to fly.”  They’re marketing themselves as burgeoning commercial suborbital payload specialists, the idea being that when companies/universities/etc. want to perform suborbital research using the new spacecraft around the corner, it’ll be cheaper to hire these guys than to train and certify their own staff for spaceflight.  -I think it’s a fantastic idea.  Heck, I’d be jazzed to sign up with them one day if the opportunity arose.

The market is so ripe that company Orbital Outfitters, a private spacesuit manufacturer, has formed to offer standardized “get me down” spacesuits to supply suborbital researchers.  Known as the Industrial Suborbital Spacesuit, or IS^3, the suit provides at least 30 minutes of emergency life support at at an altitude of 90 miles and offers imbedded communication equipment and biometric sensors, enhanced visibility, and can even be integrated into a parachute harness.

The future is now, and it looks like my dream of becoming a corporate astronaut is more realistic than ever.  All I have to do is find the right way to get my foot in the door…. er, airlock.
