NASA has decided to close down the Wide-field Infrared Survey Explorer (WISE), an orbiting telescope that has been a crucial part of space observation. Despite its past contributions, the aging telescope will be decommissioned.
Background of WISE
Launched in December 2009, WISE was designed to map the sky in infrared light, discovering celestial objects such as asteroids, stars, and galaxies. Its mission was vital in expanding our understanding of the universe.
Achievements and Contributions
Throughout its operational period, WISE discovered over 34,000 asteroids and comets and identified hundreds of thousands of stars and galaxies. Its data significantly contributed to various fields of astronomy and space science.
Reasons for Decommissioning
The decision to close WISE stems from its aging technology and the limitations it now faces in terms of functionality. The telescope’s instruments have gradually worn out, reducing its effectiveness in conducting scientific observations.
Future Implications
The decommissioning of WISE marks the end of an era in infrared space observation. NASA continues to focus on newer, more advanced technologies to replace the capabilities once offered by WISE.
