As many have said, 8 billion humans live there. But let’s not forget, we’ve identified less than 2 million other species of the estimated many millions to billions of species we share the planet with. We are only 1 species of the life on this tiny blue dot. #Earth #Orion
A small experiment on a NASA rover is tinkering with the alien atmosphere.
Millions of miles away on Mars, in a barren crater just north of the equator, a rover is wandering around, carrying a gold-coated gadget the size of a toaster. The machine inhales the Martian air and strips away contaminants. It splits the atmospheric gas into constituent parts, takes what it needs, and then reassembles that blend to create something that is in very short supply on Mars: oxygen. Real, breathable oxygen, the kind you took in as you read these sentences.
After a bit of analysis, the machine puffs out the oxygen, harmlessly releasing the molecules into the Martian environment. The act makes this very sophisticated toaster, situated in the belly of NASA’s Perseverance rover, the closest thing to a small tree on Mars.
I just watched the International Space Station fly overhead. Soundtrack: “ISS - Is Somebody Singing” by Chris Hadfield. 🤓🛰😍 Visit NASA’s spot the station to sign up for alerts.
