Now that the onboard supply of frozen coolant enabling NASA's Wide-field Infrared Survey Explorer spacecraft to map the infrared sky has run out, a "warmed up" WISE will now focus on its secondary targets: the asteroids and comets traveling together with our solar system's planets around the sun. The NEOWISE Post-Cryogenic Mission is designed to complete the survey of the solar system and finish the second survey of the rest of the sky at its new warmer temperature of about minus 334 degrees Fahrenheit using its two shortest-wavelength detectors. The survey extension will last one to four months. Interviewee is Hashima Hasan, WISE Program Scientist, NASA Headquarters.
