Cryogenic Seal for Space Launch System Handles Extreme Pressure Conditions

OmniSeal® RACO™ Spring-Energized Seals Saint-Gobain Seals Garden Grove, CA 800-544-0080 www.seals.saint-gobain.com Saint-Gobain Seals produced a cryogenic seal measuring more than six feet wide for NASA’s Space Launch System (SLS) project. Although this launch system replaced the retired space shuttle, it was built using proven hardware from the space shuttle era and previous successful exploration programs, as well as cutting-edge tooling and manufacturing technology in order to reduce development time and cost. SLS’ first mission, Exploration Mission 1 (EM-1), will go into space in late 2018, and uses Saint-Gobain seals.

NASA-Developed Platform Integrates Sensors with Smartphones

Carbon-nanotube-based gas detectors paved the way for interchangeable smartphone-savvy sensors. In 2007, when the Department of Homeland Security (DHS) issued a call for a sensor that could equip a smartphone with the ability to detect dangerous gases and chemicals, NASA Ames Research Center scientist Jing Li had a ready response. She had been developing the use of single-walled carbon nanotubes that respond to various gases and compounds for use in NASA applications such as evaluating planetary atmospheres, detecting chemicals around rocket launch pads, and monitoring the performance of life-support systems. Her proposal was awarded funding in 2008, but she needed a way for the device to “sniff” the air for samples, and a system that would allow it to interface with a smartphone.

Editor's Choice: March 2016

Algae can produce valuable products such as biofuels. A new method using forward osmosis incorporates photobioreactor tubes filled with wastewater that float in seawater. The forward osmosis removes the wastewater and concentrates the algae for harvesting, and also cleans the water released back into the seawater, creating a beneficial environmental impact.
