Image Sensors Provide Mission-Critical Data for Space Flight

Kodak CCD image sensors Eastman Kodak, Image Sensor Solutions Rochester, NY 585-722-4385 www.kodak.com/go/imagers Kodak digital technology was used on the Space Shuttle Discovery, which was launched on May 28, to capture critical images and help safeguard the well-being of shuttle astronauts during re-entry back to Earth. The image sensors are a key component of the Orbiter Boom Sensor System (OBSS), an inflight imaging system attached to the end of a 50-foot robotic arm used by shuttle astronauts to scan the underside of the orbiter for possible damage before landing.

Image of Spacecraft Landing on Mars Captured by Image Sensors

e2v CCD image sensors e2v technologies plc Elmsford, NY 914-592-6050 www.e2v.com NASA’s Mars Reconnaissance Orbiter (MRO) is currently on Mars using the probe’s High Resolution Imaging Science Experiment (HiRISE) instrument to gather data on the planet’s climate, composition, and surface features. On May 25, 2008, e2v CCD image sensors incorporated into the HiRISE captured an image of NASA’s Phoenix Mars Lander suspended from its parachute, as the lander successfully arrived on Mars. This is the first time a spacecraft has captured an image of another spacecraft landing on a planetary body. HiRISE normally points downwards, but the whole orbiter was tilted up in order to capture the image of the lander as it approached Mars.

Front Panel Hardware Considerations For ATCA, AMC, and MicroTCA Telecom Equipment

Acceptance of telecom industry standards for rack-mounted server equipment — in the form of the PCI Industrial Computer Manufacturer’s Group (PICMG) standards — is gaining momentum throughout global market channels. The objectives of those standards are certainly attractive in terms of streamlining economy and efficiency for both carriers and telecom equipment manufacturers across a number of areas. Their aim is to reduce development time and costs, as well as to help reduce the total cost of ownership. They are also intended to offer high levels of modularity and configurability while delivering high levels of service availability (99.999% and greater) and supporting appropriate scalability of system performance and capacity.

Nanophotonics Principles and Applications

The term “nanophotonics” is used to encompass the scientific study of the interaction of matter and light at the nanometer scale. It is possible to design nanometer scale devices to slow down, enhance, produce, or manipulate light by understanding how light behaves as it travels through, or otherwise interacts with, materials at the nanometer scale. Two applications where nanophotonics have had an impact on society are devices used in optical switching for telecommunications and Organic Light Emitting Diodes (OLEDs) used in display technology and lighting.

Real-Time Web-Based Image Distribution Using an Airborne GPS/Inertial Image Server

The use of geo-referenced imagery across the Internet is becoming prevalent thanks to the development of Web-based location servers such as Google Earth, TerraServer, and Yahoo Local. But users of these services are continually asking for more timely high-resolution data. Civil agencies such as firefighters, search and rescue teams, law enforcement, 911 emergency operations, border patrol operations, traffic monitoring systems, and geological survey crews — as well as the military — could benefit from a near-real-time, Web-based geospatial visualization capability.

NASA Probes Gather Solar Information

STEREO observatories and Solar Probe Johns Hopkins University Applied Physics Laboratory Laurel, MD 240-228-5000 www.jhuapl.edu NASA’s Solar Terrestrial Relations Observatory (STEREO) is comprised of two nearly identical spacecraft that were launched in 2006. They will gather images of the Sun simultaneously from different angles. These images will then be combined to produce three-dimensional pictures of coronal mass ejections. These eruptions can blow 10 billion tons of the Sun’s atmosphere into space, and can trigger severe magnetic storms on Earth that cut off electric power and communications.

Spacecraft Leak Detection System Uses Ultrasonic Sensors

Spacecraft leak detection system Invocon Conroe, TX 281-292-9903 www.invocon.com NASA has selected a spacecraft leak detection system from Invocon that would sense and locate air leaks in pressurized space stations or lunar habitat modules caused by micrometeoroid and space debris impact events. Low-cost, ultrasonic sensor arrays developed by Iowa State University are used in the system. The spacecraft structure would be monitored for leak-generated, surface- borne ultrasound by means of a flexible and modular electronics package with fully integrated data sensors, data acquisiti
