Joel Levine: Why we need to go back to Mars

Hello everybody today I am going to talk about a object. This is not a ordinary object. Guess what it is? It's a plane in space. It looks like a UAV in space. It's really big because it has to sustain all of the preasure in space. This will change ways of things because this thing can take really good photos zoomed in. So we can figure out if things are alive on earth. Because they have signs of methane in space so 99.99 percent of humans breath in methane.
