ALT A picture of a massive, silver, statuesque piece of hardware inside a cavernous testing chamber. The image is mostly dark, with an illuminated section in the lower center half of the picture. The hardware has two large, vertical silver metal posts on either side of it, and two silver metal posts that cross horizontally between them. In the center of those posts is a large portion of silver thermal blanketing that is gathered toward the middle. White lights shine upward from the base of either side of the hardware. A line of six, small, white lights with a blueish starburst effect crown the hardware. Credit: NASA/Bill Stafford

ALT An artist's concept shows the Wide-field Infrared Survey Explorer, or WISE spacecraft, in its orbit around Earth. The spacecraft is about the height and weight of a big polar bear, only wider. It measures 2.85 meters tall (9.35 feet), 2 meters wide (6.56 feet), 1.73 meters deep (5.68 feet) and weighs 661 kilograms (1,433 pounds). It is composed of two main sections: the instrument and the spacecraft bus.
ALT About two dozen representatives from NASA, FEMA, and the planetary defense community are in a conference room seated at large tables with laptop computers open. They watch a speaker deliver a presentation, with two large screens displaying a Powerpoint slide showing information about the exercise in the background.
