BOULDER, Colo. –

The University of Colorado will host a public lecture Tuesday on NASA’s Themis mission, which was designed to study the magnetic storms responsible for causing auroras at Earth’s poles.

Understanding these “magnetospheric substorms” can help astronomers understand full-scale space storms, which can disable spacecraft, radio communication, GPS navigation and power systems.

Astronomer Xinlin Li will discuss the Themis mission beginning at 7:30 p.m. at the Laboratory for Atmospheric and Space Physics, 1234 Innovation Drive, Boulder.
