Why Space Gets More Dangerous the Further You Travel From Earth

Deep space gets more dangerous the further a crew travels from Earth, and this long space documentary follows one imaginary crew of four outward to see why. They leave the launch pad and pass through low Earth orbit, the Van Allen belts and the space around the Moon, then cross toward Mars and carry on past Jupiter, the outer planets, the edge of the Sun's wind and the Oort Cloud. Along the way it looks at the 1.8 millisieverts a day that Curiosity measured on its way to Mars, the two new radiation belts left behind by the May 2024 solar storm, and Voyager 1 reaching one light day from Earth in November 2026. 0:00 Introduction 1:33 Five shelters on the ground 13:25 Low Earth orbit 21:06 Through the Van Allen belts 29:06 Past the magnetic field 37:07 The open crossing 44:48 At the distance of Mars 52:47 The asteroid belt 1:00:29 Jupiter's radiation 1:08:30 Saturn, Uranus and Neptune 1:16:25 The edge of the Sun's wind 1:24:24 Into the Oort Cloud 1:32:25 The space between the stars 1:50:27 Looking back toward home Sleeping Cosmos makes long space documentaries for falling asleep to, studying beside, or simply winding down when the day is done. Each one travels slowly out into the universe and finds its way back again, a single carefully researched story at a time, gently told. Good for: 🌙 Falling asleep as a small crew drifts out past the planets 📖 Studying or reading with a long voyage beyond the Sun in the background 🌌 Unwinding at night while the Sun shrinks to one bright star To read more about what the crew meets: Radiation measured inside Curiosity's capsule on the way to Mars, Southwest Research Institute https://www.swri.org/press-release/sw...
