The 40 cm diameter WISE telescope is an all aluminum optical system that will produce images of the sky with 2.75 arcsec resolution in four infrared spectral bands. Here the lead optical test engineer attaches the back-end imager optics to the afocal. This entire telescope will be mounted inside the WISE cryostat and cooled to about 17K. The WISE telescope was developed by L3 Communications-SSG.

Metal eater: Metallosphaera sedula can draw energy from a copper-iron sulfide called chalcopyrite, the black substance shown here. As it feeds, it produces copper ions (green), iron oxide (orange), and sulfur (yellow). The organism uses the energy from the sulfides to produce acetyl-CoA, a fundamental building block in cells. Researchers have been able to engineer organisms to convert acetyl-CoA into butanol and other liquid fuels. Credit: Robert Kelly, North Carolina State
