German educational design studio Kurzgesagt explores an alternative means of getting to space. To wit:
Getting to space is incredibly hard, expensive and needs a lot of resources.A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.
An image of five Saturnine moons above the ring plane captured in 2011, by the Cassini spacecraft’s narrow-angle camera. To wit:
Left to right are small moons Janus and Pandora respectively 179 and 81 kilometres across, shiny 504 kilometre diameter Enceladus, and Mimas, 396 kilometres across, seen just next to Rhea. Cut off by the right edge of the frame, Rhea is Saturn’s second largest moon at 1,528 kilometres across. So how many moons does Saturn have? Twenty new found outer satellites bring its total to 82 known moons, and since Jupiter’s moon total stands at 79, Saturn is the Solar System’s new moon king.The newly announced Saturnian satellites are all very small, 5 kilometres or so in diameter, and most are in retrograde orbits inclined to Saturn’s ringplane.
YouTube education channel Kurzgesagt explores the increasing hazard caused by every new rocket we launch into space and the deadly cloak of debris that may one day make space travel too dangerous to attempt.
