NASA spacecraft reactivated to hunt for asteroids: Probe will assist agency in search for candidates to explore

A NASA spacecraft that discovered and characterized tens of thousands of asteroids throughout the solar system before being placed in hibernation will return to service for three more years starting in September, assisting the agency in its effort to identify the population of potentially hazardous near-Earth objects, as well as those suitable for asteroid exploration missions.

The Wide-field Infrared Survey Explorer (WISE) will be revived next month with the goal of discovering and characterizing near-Earth objects (NEOs), space rocks that can be found orbiting within 45 million kilometers (28 million miles) from Earth’s path around the sun. NASA anticipates WISE will use its 16-inch (40-centimeter) telescope and infrared cameras to discover about 150 previously unknown NEOs and characterize the size, albedo and thermal properties of about 2,000 others—including some of which could be candidates for the agency’s recently announced asteroid initiative.

“The WISE mission achieved its mission’s goals and as NEOWISE extended the science even further in its survey of asteroids. NASA is now extending that record of success, which will enhance our ability to find potentially hazardous asteroids, and support the new asteroid initiative,” said John Grunsfeld, NASA’s associate administrator for science in Washington. “Reactivating WISE is an excellent example of how we are leveraging existing capabilities across the agency to achieve our goal.”

NASA’s rodent habitat, developed at Ames Research Center in Moffett Field, California, serves as a home away from home for mice on the International Space Station. Previous rodent experiments aboard space shuttles contributed to the development of new drugs now fighting osteoporosis on Earth.
