OTTAWA, Ont., October 29, 2015 (ISS PR) — Integrated Spaceflight Services LLC (‘ISS’) of Boulder, Colo. announced today that it has completed the first zero g evaluation of a commercial spacesuit. The 3G IVA spacesuit, manufactured by Final Frontier Design (‘FFD’) of Brooklyn, N.Y., was tested through four zero g flights on a specially-modified Falcon 20 research aircraft..

ISS offers reduced gravity services to the research and education community and coordinates zero g testing, high-G testing, egress and operability testing, mission simulation, and human factors testing of FFD’s spacesuits through its upper-atmospheric research and education program, Project PoSSUM.

“This was the first step in an extensive test plan that will evaluate the FFD IVA spacesuit in conditions that best approximate the environments in which they were designed to operate.” said Dr. Jason Reimuller, President of ISS, “This was a complicated test protocol; we want to make sure that our methodology is well established before we advance to other tests.”

According to ISS, the Falcon 20 aircraft was chosen for its exceptional quality of zero g that best approximates the orbital environment, as well as a cabin interior that best replicates several space vehicles being produced. On each of the four flights, a series of parabolic maneuvers were conducted in which the test subjects would perform range of motion tests, fine motor skills tests, seat egress and ingress tests, and assisted seat ingress tests. On-board suit pressurization and monitoring systems were also evaluated in flight.

The 14 participating Project PoSSUM graduates had all been previously trained in spacesuit and microgravity operations and rehearsed in teams of five prior to flight. Spacesuit test subjects included Dr. Shawna Pandya of Edmonton, Alta; Callum Wallach of Auckland, New Zealand, Gavin James of Daytona Beach, Fla., Deniz Burnham of Fairfield, Calif.; Dr. Ross Lockwood of Edmonton, Alta., Dr. Ulyana Horodyskyj of Boulder, Colo.; Michael Mastin of Ketchikan, Alaska; and Jim Kuhl of Syracuse, N.Y. The tests were directed by Kari Love of Brooklyn, N.Y. and Dr. Jason Reimuller of Boulder, Colo.

“FFD is consistently impressed by the credentials and commitment of Project PoSSUM graduates. Data collected on suit performance helps build our case on the road to human rating and spaceflight.” said Kari Love, co-owner of FFD.

The next stage of spacesuit evaluations is planned for April 19-22, 2016. Interested persons should contact Project PoSSUM at
