CCD Imaging Sensors Aid Hubble in Exploring the Universe

Charge coupled device (CCD) imaging sensors e2v Chelmsford, UK 44 (0)1245 493493 www.e2v.com e2v CCD imaging sensors were launched recently on the Space Shuttle Atlantis as part of a mission to upgrade and repair the Hubble Space Telescope. The imaging sensors equip the Wide Field Camera 3 (WFC3), a new instrument installed on Hubble to take largescale, extremely clear and detailed pictures of the universe over a very wide range of colors. The mission equipped the telescope to explore the universe in greater detail by replacing equipment and installing new instruments.

Assembly Machines Produce Optics for NASA’s NuSTAR Telescope

Cylindrical optics module assembly machines ABTech Swanzey, NH 603-358-6431 www.abtechmfg.com ABTech has completed the first of two cylindrical optics module assembly machines for Columbia University’s Nevis Astrophysics Laboratory. The multi-axis air bearing machine platforms are optimized for the construction of high-energy xray telescopes. The optics modules will be used to produce the telescope optics for NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) program. ABTech will provide installation and on-sight operational training to Columbia University scientists at the Nevis Laboratory and ongoing technical support during the production of the optics modules.

Laser Tracker Ensures Accurate Alignment of Ares I Components

FARO® Laser Tracker FARO Technologies Lake Mary, FL 800-736-0234 www.faro.com Making its first flights to the International Space Station by the middle of the next decade, the Orion crew exploration vehicle is part of the Constellation Program, which will send human explorers back to the Moon, and then to Mars and other destinations in the solar system. Future astronauts will ride into orbit on Ares I, Orion’s launch vehicle, which uses a single, five-segment solid rocket booster. NASA’s first test flight, called Ares I-X, will provide NASA with an early opportunity to test and prove the hardware, facilities, and ground operations associated with the Ares I.

Measuring the Color and Appearance of Special-Effect Paint

Manufacturers that design, formulate and apply coatings have struggled for years to find a rigorous and easy-to-use method that reliably measures the color and appearance of special-effect paints. Companies tried to relate measurements taken with handheld spectrophotometers that collect colorimetric data from several in-plane angles to events that occurred in production processes, but these instruments, by their nature, could not collect the essential data points to yield reliable results. Other companies have tried to skirt the problem by creating a coarseness index or “sparkle” metric that relies on photographic images taken in-plane, but this method is easily confused and insufficient for rigorous analysis.
