Kinneas participates in NASA Press Conference
Today at noon EDT NASA held a teleconference to discuss the ‘Conditions at the Edge of the Solar System’ with the IBEX team and our very own Kinneas was invited to participate as a member of the press and call in his question for the team.

IBEX Spacecraft Finds Discoveries Close to Home
Imagine floating 35,000 miles above the sunny side of Earth. Our home planet gleams below, a majestic whorl of color and texture. All seems calm around you. With no satellites or space debris to dodge, you can just relax and enjoy the black emptiness of space.
But looks can be deceiving.
In reality, you’ve unknowingly jumped into an invisible mosh pit of electromagnetic mayhem — the place in space where a supersonic “wind” of charged particles from the Sun crashes head-on into the protective magnetic bubble that surrounds our planet. Traveling at a million miles per hour, the solar wind’s protons and electrons sense Earth’s magnetosphere too late to flow smoothly around it. Instead, they’re shocked, heated, and slowed almost to a stop as they pile up along its outer boundary, the magnetopause, before getting diverted sideways.
Space physicists have had a general sense of these dynamic goings-on for decades. But it wasn’t until the advent of the Interstellar Boundary Explorer or IBEX, a NASA spacecraft launched in October 2008, that they’ve been able to see what the human eye cannot: the first-ever images of this electromagnetic crash scene. They can now witness how some of the solar wind’s charged particles are being neutralized by gas escaping from Earth’s atmosphere.
