Aurora Delivers NASA Space Suit Simulator
Special To The Packet
Aurora Flight Sciences announced that it has delivered a completed Space Suit Simulator (S3) to NASA following the successful completion of a Phase II Small Business Innovative Research effort. Aurora collaborated with Professors Dava Newman and Jeffrey Hoffman of the Massachusetts Institute of Technology (MIT) Department of Aeronautics and Astronautics, as well as Professor Grant Schaffner from the University of Cincinnati, for this program.
The S3 was developed to meet NASA’s research and training needs. Pressurized space suits impose high joint torques on the astronaut, reducing mobility for upper and lower body motions. Because of the highly altered mobility capabilities and metabolic cost of movement when wearing a space suit, it is necessary for suits to be worn during many aspects of astronaut training and ground-based research. Using actual space suits is problematic due to the expense, bulk, weight in Earth’s gravity, and difficulty in donning/doffing.
Aurora has developed a low-profile, lightweight, space suit simulator to provide high-fidelity emulation of NASA’s Extra-Vehicular Mobility Unit, the EMU. “An astronaut experiences resistance from the space suit primarily in his or her joints, such as the knees, hips, and shoulders. We have developed an exoskeleton that includes actively controlled resistive elements at each of the lower body joints,” said Dr. Jessica Duda, Aurora’s Principal Investigator for this project. “By using active control, we are also able to calibrate the joint torques for current or future space suits.” The current EMU requires very high metabolic costs (fatigue and calories burned) due to the energy required to bend the pressurized limbs. Future suit designs will focus on reducing joint torques. The S3 provides a means of measuring the metabolic costs of various joint torque configurations to aid in developing an optimized design.
Working with MIT, Aurora tested each of the joint concepts on an anthropometric robot with instrumented joints and verified the torques provided by each of the joints. The completed S3 is adjustable for human subjects up to 95th percentile male and is expected to be used in university field trials this summer.
ReMax Expands To Starkville
Special To The Packet
RE/MAX Partners is proud to announce the opening of a second office location in Starkville, MS. RE/MAX Partners is well-established, real estate leader in Columbus and is expanding to Starkville to better serve Buyers and Sellers in the full Golden Triangle. Broker/Owners Michael and Kris Davis have been associated with the RE/MAX network since 2008, during which time they were recognized as RE/MAX Mississippi’s Broker/Owners of the Year.
RE/MAX Partners’ Broker/Owner, Michael Davis, says the expansion to the Starkville area was a natural progression. “We service so many Buyers coming to the Golden Triangle area, that it is critical to have a working knowledge and presence in both Starkville and Columbus. Our ability to work in both markets gives us an edge with our Buyer and Seller clients, as well as the HR Managers and Relocation Directors for companies located in the Golden Triangle.”
Joining the RE/MAX Partners’ team is Kay Regimbal, Vice President of Development for Tabor Construction & Development. Kay, a licensed REALTOR since 2001, specializes in the sale of condominiums and commercial land, with properties like Belle Grove, University Club, The Lofts of Central Station and Myrtle Creek Business Park, among her listings.
RE/MAX Partners’ Starkville location is conveniently located in The Lofts of Central Station on South Montgomery Street. For more information, please visit www.rmx partners.net or contact Michael Davis at 662-327-7705 or michael. davis @remax.net.
