The LAMP mission, short for Loss through Auroral Microburst Pulsations, launched on Saturday, Marc 5, 2022, aboard a Black Brant IX suborbital sounding rocket. The mission will study an often overlooked kind of aurora, called a pulsating aurora, and test a theory on what causes them.

Like all aurora, a pulsating aurora is set alight by electrons (and occasionally protons) from near-Earth space. These electrons plunge into our atmosphere and collide with atoms and molecules, causing them to glow in their distinctive colors – red and green by oxygen, blue by nitrogen – as they release their excess energy.
