Scientists have theorized on the origin of the water plumes possibly erupting from Jupiter’s moon Europa. Recent research adds a new potential source to the mix.

PASADENA, Calif. (NASA PR) — Plumes of water vapor that may be venting into space from Jupiter’s moon Europa could come from within the icy crust itself, according to new research. A model outlines a process for brine, or salt-enriched water, moving around within the moon’s shell and eventually forming pockets of water – even more concentrated with salt – that could erupt.

Senate and House committees held hearings on consecutive days last week about space situational awareness (SSA) and space traffic management (STM), i.e., the ability to accurately track objects in Earth orbit and to avoid dangerous collisions that could knock out satellites and even render entire orbits unusable.

The overall conclusion was that, although progress is being made, we’re not nearly as aware as we need to be as orbital debris poses an ever bigger problem and companies prepare to launch tens of thousands of new satellites.

“Near Earth space is geo-politically contested, it’s commercially contested and it’s in dire need of environmental protection because it is a finite resource,” said Moriba Jah, an associate professor of astronautics at the University of Texas.
