Chinese space station Tiangong-1, will fall to Earth on April 1, later than expected, because of the weaker sun activity, Space.com reports.
What happened: Per Space.com, the sun's activity results in "charged particles" that hit Earth's atmosphere. The particles can increase gas density in space, which impacts the drag on the space station. Because the sun's activity has been weak, there have been fewer particles, and therefore weaker drag, which will make Tiangong-1 "descend more slowly than expected."
