NASA Turns to 3D Metal Printing for SLS Propulsion Program

Direct Metal Laser Sintering (DMLS) Stratasys Direct Manufacturing Valencia, CA 888-311-1017 www.stratasysdirect.comNASA’s Marshall Space Flight Center is currently leading the development of the Space Launch System (SLS) program, which is building a heavy-lift launch vehicle to carry human explorers and science payloads to new frontiers. Today, one important technology being explored by the team at Marshall is additive manufacturing, or 3D printing, as it relates to manufacturing hardware and propulsion for the SLS rocket. The center dedicated resources to materials and technologies research, using their latest liquid rocket injector development as one optimal project for testing out the capabilities, costs, and benefits of additive manufacturing processes. One goal of additive manufacturing is to consolidate parts to reduce labor and weight, and create an overall more efficient part with increased complexities that help optimize injectors for future applications.

NASA Leverages Analytical Modeling to Improve Astronaut Mission Readiness

Probabilistic modeling Charles River Analytics Cambridge, MA 617-491-3474 www.cra.comNASA has contracted with Charles River Analytics to develop a system to measure and assess astronaut workload. The system for Cognitive Assessment and Prediction to Promote Individualized Capability Augmentation and Reduce Decrement, or CAPT PICARD, will measure, assess, and predict cognitive workload to assist astronauts or mission control in responding more effectively. Astronauts sent on manned NASA missions face long periods of minimal cognitive workload followed by sudden, fast-tempo operations. In addition, disrupted sleep, long-term motion exposure, and lack of normal gravity may impair cognitive and psychomotor functioning, resulting in fatigue, stress, and decreased mood.

Highway Sensor Deployment Gives Valuable Data to ‘Connected’ Drivers

In an effort to improve traffic flow, driver safety, and asset management, the Michigan Department of Transportation (DOT) has installed 17 sensors on a 50-mile stretch of one of the state’s busy Interstate highways. The “connected corridor” deployment will provide useful data for drivers of cars equipped with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication technology.
