We welcomed Dr. Jason Reimuller to the program to discuss Project PoSSUM (Polar Suborbital Science in the Upper Mesosphere).  For more information, please visit their website, www.projectpossum.org. In the first segment of this 1 hour 29 minute discussion, Dr. Reimuller started off by telling us the history of Project PoSSUM and its focus on noctilucent clouds.  Jason described noctilucent clouds and their importance.  I also suggest you read about them on their website at http://projectpossum.org/2015-possum-nlc-campaign/about-noctilucent-clouds.  We talked about the high latitudes, the short window for observing these clouds, and the interest in using the XCOR Lynx vehicle as the RLV of choice though other suborbital RLVs are also being considered.  We talked about funding as a NASA Flight Opportunities Program and down the road a specialized Kickstarter program.  Jason also described the payloads, missions and the Aeronomy Lab, the PoSSUM observatory and much more.  He described the types of experiments the scientists want to do during the suborbital flight. Jason also pointed out the use of a general aviation turbo-Mooney aircraft for noctilucent cloud observation, plus the rocket flight profile for maximum viewing and studying during the science mission.

In the second segment, we talked about how Project PoSSUM can enable and influence science globally plus the international interest in science missions to study these clouds.  Here, Jason pointed out that their choice vehicle was actually the Lynx Mark II.  A listener asked if the clouds were also present in the deep southern latitudes and they are during the southern hemisphere summer as they are in the northern hemisphere summer.  Given that Jason had worked on the NASA Constellation program, I asked him questions about Constellation of which he had much to say.  He also expressed a concern regarding the private rocket companies and their astronaut rescue and recover programs. He talked about the Constellation rescue and recovery program, the trades they had to consider, plus all the variables that had the potential to impact a crew rescue & recovery attempt. He also described the infrastructure in place to aid in rescue and recovery for government missions but that this infrastructure may not be applicable or available to private launch vehicles and commercial astronauts.  Connie wanted to know if there was any difference in the noctilucent clouds over land as compared to the oceans.  We also talked about science mission conclusions regarding climate change issues.
