Noctilucent Cloud and Aeronomy Research

Noctilucent clouds are rare ‘space clouds’ that are believed to be sensitive indicators of global climate trends. Too high to reach by aircraft yet too low to reach by satellite, Project PoSSUM will explore these clouds using balloons and suborbital manned spacecraft.

What are the dynamics of our upper-atmosphere and what can this say about our changing global climate? In December 2017, PoSSUM instrumentation will fly as part of NASA’s ‘PMC Turbo’ mission to better answer this question by studying noctilucent cloud features over Antarctica. Students from around the world can participate! (credit: NASA)

Are noctilucent clouds a harbinger of climate change? Can manned suborbital spacecraft help us better understand this? NASA thinks so! PoSSUM Scientist-Astronauts will fly instruments around these clouds to build extremely precise 3D models of our upper atmosphere which can help us better address these key questions.

Bioastronautics and Human Factors Research

How well can man perform in space? PoSSUM Members work with Final Frontier Design and Integrated Spaceflight Services to test and evaluate new spacesuits and emerging space technologies in analog environments.

How can we understand how well prototype spacesuits will perform once needed in space? To help answer this, PoSSUM members evaluate spacesuits in analog environments here on Earth including microgravity, high-G, and high-altitude environments!

Operability and Human Factors Research

Dr Sarah Jane Pell prepares to test functionality of the Final Frontier IVA spacesuit in a Mooney research aircraft, an analog operational environment to a spacecraft.

How well can one operate a spacesuit in a cramped operational environment like in a Soyuz or Dragon capsule? PoSSUM members perform comparable procedures in research aircraft and in simulated spaceflight to find out!

Analog Terrestrial Environment Research

How can an astronaut plan for and perform procedures after a contingency landing? How well can an astronaut in a spacesuit escape from a distressed spacecraft? How can tools be designed that will function well on the Moon or Mars? These are questions that PoSSUM members seek to answer by studying spacecraft egress methodology, post-landing environments, and analog terrestrial environments.
