Spectrometer Helps NASA Detect Water in Excavated Moon Matter

QE65000 Spectrometer Ocean Optics Dunedin, FL 727-733-2447 www.oceanoptics.comAn Ocean Optics QE65000 spectrometer has contributed measurements to the Lunar Crater Observation and Sensing Satellite (LCROSS) mission, helping NASA scientists to officially confirm the presence of water on the Moon. The spectrometer, dubbed ALICE, was custom re-engineered by Aurora Design & Technology to withstand the extreme temperature, radiation, shock, and vibration of space.

Near-Infrared Cameras Indicate Signature of Water on the Moon

InGaAs shortwave infrared (SWIR) cameras Sensors Unlimited, Goodrich Corp. Princeton, NJ 609-520-0610 www.sensorsinc.comShortwave infrared (SWIR) cameras from Sensors Unlimited were instrumental in NASA’s LCROSS mission to find water on the Moon. The cameras were selected for the mission more than three years ago, and were integrated into the imaging payload of the shepherding spacecraft.

Connector Improves Reliability, Cuts Cost on Engine Production Line

HARTING North America was recently asked to solve some of the problems associated with power distribution and motion control on a vehicle manufacturer’s long conveyor and engine block production line. The line’s system integrator needed to reduce installation costs to be competitive with other potential suppliers, and the end customer was looking for higher reliability and ease of maintenance.

Taking COTS to the Next Level in Vetronics Subsystems

Embedded vetronics (vehicle electronics) subsystems for rugged deployed ground vehicles have long benefited from the reduced risk, faster time to market, and long lifecycle support offered by COTS board vendors. Recent advances in open standards developments, namely the OpenVPX/VITA 65 specification that defines system-level interoperability profiles for VPX architecture boards and backplanes, promise to take the COTS model from the board to the subsystem level, enabling faster deployment of proven, standards-based fully integrated enclosures.

Wafer-Level Lens Alignment

Over one billion cell phones with cameras are sold every year, and this number has been increasing annually at a rate of about 15 percent for the past 7 years. Approximately 80 percent of cell phones now have embedded cameras, with about 20 percent of new cell phones having two cameras – one on the back for taking photographs and one on the front for videoconferencing.

Software Aids Design of Ares V Composite Shroud Structure

NASA’s Ares V space launch vehicle makes significant use of composites, and during flight, the shroud of the Ares V will separate into four petals to release the Lunar Lander. In the design of the structure, the aerodynamic pressure on the shroud is resolved into internally distributed forces. A combination of two software packages — HyperSizer structural sizing software and Abaqus FEA (finite element analysis) software from SIMULIA (Providence, RI) — was used to model and simulate this process.
