Commercial Astronaut Training

Although Brien Posey is best known for his Information Technology related accomplishments, he is also currently training as a Commercial Scientist-Astronaut Candidate. To date, Brien has completed extensive suborbital space flight training through the Association of Spaceflight Professionals (formerly Astronauts for Hire) and Project PoSSUM (the first private, manned suborbital research program). In addition, Brien leads the Association of Spaceflight Professionals' Technology and Engineering group, which has been tasked with developing new technologies that may eventually fly in space.

Spacesuit and Simulator Technician Qualification Program

Daytona, Florida - October 2017

  • Qualified to pilot the PoSSUM suborbital spaceflight simulator on noctilucent cloud tomography missions
  • Trained in the safe donning, doffing, and operational procedures for a Final Frontier Design, Intra-vehicular Activity (IVA) spacesuit

Microgravity Spacesuit Evaluation

Ottawa Canada, October 2017

BIO-103 was the third series of microgravity flight testing for the Final Frontier Design IVA spacesuit. Referred to internally as the "visor down test", this was the first parabolic flight campaign in which the spacesuit's visor was closed and the suit was pressurized. Test objectives included:

  • Test the ability of the suited subject to operate the PoSSUM science instruments in microgravity
  • Test the subject's ability to operate flight controls
  • Test the suited subject's ability to accurately pressurize and depressurize the spacesuit to a predetermined pressure.
  • Test the subject's ability to open and close the visor
  • Test the suited subject's ability to release and refasten the five point harness while weightless

My role in this flight campaign was that of suited subject, and I was therefore responsible for performing the various tests while wearing a spacesuit.

Space Medicine and Human Performance

Project PoSSUM / Project OTTER, September 2017

Space Medicine and Human Performance (EVA-101) focused primarily on post landing contingencies following an off-nominal spacecraft landing in a remote area. In addition to learning about  spaceflight physiology and space medicine, the team learned how to triage and treat injuries stemming from an off-nominal landing.

Project OTTER (Operational Tools and Techniques for Extravehicular Research)

Brien Posey is a member of the inaugural Project OTTER class (EVA-101). Project OTTER is a cooperative effort between Project PoSSUM and Final Frontier Design, with the goal of developing and testing EVA spacesuits. The program will culminate in a series of underwater EVA research missions. The Project OTTER requirements include:

  • Project PoSSUM Scientist-Astronaut Qualification Program (prerequisite)
  • EVA-101: Space Medicine and Human Performance
  • EVA-102: Saturation Diving and EVA Operations
  • EVA-103: Lunar and Martian Geology and Analog EVA
  • EVA-104: Underwater EVA Suit Operations
