"From the Ted Talk by Dave Brain: What a planet needs to sustain life"

Unscramble the Blue Letters

Well, one idea is it escaped away to scape. Atmospheric particles got enough energy to break free from the gravity of the planet, escaping away to space, never to return. And this happens with all bodies with atmospheres. Comets have tails that are incredibly viisble reminders of atmospheric escape. But Venus also has an atmosphere that epacess with time, and Mars and ertah as well. It's just a matter of degree and a matter of salce. So we'd like to fgurie out how much escaped over time so we can explain this transition.

Well, one idea is it escaped away to space. Atmospheric particles got enough energy to break free from the gravity of the planet, escaping away to space, never to return. And this happens with all bodies with atmospheres. Comets have tails that are incredibly visible reminders of atmospheric escape. But Venus also has an atmosphere that escapes with time, and Mars and Earth as well. It's just a matter of degree and a matter of scale. So we'd like to figure out how much escaped over time so we can explain this transition.
