Will we ever be able to teleport? - Sajan Saini
Adults ScienceIs teleportation possible? Could a baseball transform into something like a radio wave, travel through buildings, bounce around corners, and change back into a baseball? Oddly enough, thanks to quantum mechanics, the answer might actually be yes... sort of! Sajan Saini explains.
Why It's HARD To Land on Mars
Adults ScienceThis video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you can do a powered descent in a flimsy tinfoil spacecraft like the Lunar Module, and when there's plenty of atmosphere you can do an unpowered descent via heat shield and parachutes like the space shuttle, Apollo command module, Soyuz, Huygens, etc. But on Mars with its thin air, you have to do both powered & unpowered descent, getting the worst of both worlds.
