NASA delays launch of spacecraft

STORY HIGHLIGHTS
  • An equipment problem delays launch aimed at scanning for hidden cosmic objects
  • Mission is now scheduled to launch Monday morning
  • Wide-field Infrared Survey Explorer mission will circle Earth over the poles

(CNN) -- An equipment problem forced NASA early Friday to delay the launch of a spacecraft aimed at scanning the entire sky to discover hidden cosmic objects, the U.S. space agency said.

The Wide-field Infrared Survey Explorer mission is now scheduled to launch Monday morning.

NASA crews will tackle an anomaly in the motion of a booster steering engine by removing and replacing a suspect component on Friday, the agency said on its Web site.

"The WISE spacecraft will circle Earth over the poles, scanning the entire sky one-and-a-half times in nine months. The mission will uncover hidden cosmic objects, including the coolest stars, dark asteroids and the most luminous galaxies," NASA said.
