NASA-Funded Project Investigates Deep-Sea Life

The Monterey Bay Aquarium Research Institute (MBARI) in Moss Landing, CA, is using funding from organizations including NASA’s Jet Propulsion Laboratory (JPL) to develop the Environmental Sample Processor (ESP), an electromechanical/ fluidic instrument that collects discrete water samples from the ocean subsurface. It concentrates microorganisms (particulates), and automates application of molecular probes to identify microorganisms and their gene products. The ESP also archives samples so that further analyses may be done after the instrument is recovered. NASA is considering how elements of the ESP might be useful in looking for life on other planets.

CAD/Finite Element Analysis (FEA) Modeling Environment

ALGOR, Inc., Pittsburgh, PA, has released ALGOR V20, an integrated CAD/finite element analysis (FEA) modeling environment for working with imported CAD models or building original models. New features include design scenarios that let a single FEA model contain numerous analyses; a software wizard for creating bolts and fasteners; design studies and size optimization, which provide automated tools for achieving optimal designs based on user-supplied criteria; and improved meshing capabilities. Other new features are a k-epsilon turbulence model for fluid flow analysis, which allows specification of wall roughness, and a reinforced (rebar) concrete element and material model for realistic simulation of concrete structures. The software also supports multiple rotating frames of reference for 3D modeling of complex fans and similar systems, and the capability to define results-based load curves for Mechanical Event Simulation. Enhanced multiphysics analysis includes coupled unsteady fluid flow and transient heat with buoyancy effects.

Multi-Bit-Rate Switcher Is Part of High-Definition Upgrade at NASA

HANABI HVS-3800HS Multi-Bit Rate Switcher FOR-A Waltham, MA 714-867-3311 www.for-a.com NASA’s Goddard Space Flight Center (GSFC) in Greenbelt, MD, manages the Hubble Space Telescope that has, since its launch in 1990, recorded more than 700,000 images in its quest to explore the solar system. Recently, NASA announced plans for a fifth servicing mission to the Hubble in which the FOR-A HANABI switcher was used in a live press conference to produce and record the news in high-definition (HD). The images were then converted for distribution to the public via NASA-TV. “Given that the Hubble is so important, we wanted to be able to announce this in HD for historical purposes,” said Patrick Kennedy, GSFC’s TV production manager.
