Shulou( Report--, December 21 (Xinhua)-- NASA recently issued a press release announcing that the near-Earth object wide area Infrared Survey probe (NEOWISE) is gradually out of orbit due to solar activity and is expected to re-enter the Earth's atmosphere in 2025, completely burning up.

NEOWISE resumed its mission on December 13, 2013, observing more than 3000 near-Earth objects, strengthening the international planetary defense strategy and supporting another NASA mission with distant asteroids.

The existing astronomical consensus is that the sun experiences a cycle of increased activity about every 11 years, called the solar maximum.

During this period, solar activity such as solar flares and coronal mass ejections became more frequent and heated our planet's atmosphere, causing it to expand, increasing the resistance of satellites orbiting Earth and causing it to slow down. learned from the report that NASA said that in the middle of this solar maximum, NEOWISE can no longer maintain its orbit above the atmosphere and will gradually get out of orbit and burn into the Earth's atmosphere.

Launched in 2009, NEOWISE has recorded more than 200 new near-Earth objects and observed more than 3000 objects.
