LASP researchers have discovered an atmospheric escape route for hydrogen on Mars, a mechanism that may have played a significant role in the planet’s loss of liquid water.
The findings describe a process in which water molecules rise to the middle layers of the planet’s atmosphere during warmer seasons of the year and then break apart, triggering a large increase in the rate of hydrogen escape from the atmosphere to space in a span of just weeks.

I admit that I love giving presentations on New Horizons to public audiences. It’s the killer combination of Pluto and space exploration. Everyone digs it. The best are astronomy clubs—just bursting with enthusiasm. And my favorite group of all time is the Rocky Mountain Star Stare (RMSS). Based in Colorado Springs, RMSS meets every year on a piece of land close to the Colorado–New Mexico border that is far from city lights. The trek is worth it—the Milky Way blazes across the sky.And these guys have brought along the most amazing astro-geek equipment.
