  • Introduction to Video Content
  • In the latest episode of For All Mankind, titled 'Happy Valley', the science behind traveling to Mars takes center stage. With a distance of 56 million kilometers separating us from the Red Planet, the traditional means of propulsion alone won't bridge this gap. However, there is a potential solution lurking in the untapped force of light. In this article, we will delve into the science behind harnessing light for space travel.Light, we know, is made up of photons. While photons themselves are massless, they possess momentum. Individually, a single photon floating through space would have little impact. Yet, when we consider the vast number of photons emitted by the Sun—trillions per second—then their collective momentum becomes significant. This is especially true in the absence of gravity.The question then arises: How can we harness this momentum to propel space vehicles? The answer lies in utilizing a large and reflective structure that can bounce light. Enter the solar sail, made of a thin and reflective material called mylar. When photons collide with the reflective surface of the sail, they transfer their momentum, effectively pushing the ship forward.Naturally, the more photons a solar sail captures, the greater its momentum. Thus, to propel a spacecraft the size of NASA's Sojourner, an incredibly large sail would be required. Constructing such a sail poses numerous challenges and the launch would necessitate even more fuel. Nevertheless, with a large enough sail, a spacecraft could theoretically ride the sunlight all the way to Mars.While the concept of riding photons through space may sound like science fiction, it is indeed grounded in scientific principles. In fact, researchers are currently investigating the use of lasers and lighter materials to maximize the potential of solar sails. Furthermore, we are already witnessing the proof of concept with a toaster-sized spacecraft orbiting the Earth, propelled solely by a solar sail.As the race to Mars intensifies in the world of For All Mankind, the intriguing possibilities of light-based propulsion present themselves. Will our characters seize this unexpected advantage? Only time will tell. In the meantime, let us marvel at the fascinating science behind the fictional journey to the Red Planet.
  • Subtitles section
  • There are at least 56 million kilometers standing between us and Mars.
  • That's a long way to travel, But what if there was something that could help?
  • An untapped force all around us that could give us an extra push.
  • I'm Wren Schmidt, and we're exploring the science behind For All Mankind.
  • With The journey to Mars heating up between NASA, Helios, and the Soviet Union, we wanted to create a thrilling come-from-behind surprise.
  • What could give someone an unexpected edge in this literal space race?
  • The answer led us into the light.
  • Light is made up of photons.
  • Photons don't have any mass, but they do have momentum.
  • A single photon soaring through space can't do much.
  • But the sun pumps out trillions of photons per second.
  • And all these photons in zero gravity, well, they can pack a punch.
  • So how can we harness them?
  • We need something large and reflective.
  • Something that can bounce light.
  • A solar sail made of mylar can do just that.
  • The photons bounce off the reflective sail, transferring their momentum, pushing the ship forward.
  • More photons means more momentum.
  • The impact may be small, but it's steady.
  • It's a little boost that can really add up.
  • To push a ship as big as NASA's Sojourner, you'd need a really big sail.
  • Making a sail that big would be challenging, and the bigger the sail, the more fuel you'd need to launch.
  • But a ship with a large enough sail could ride the sunlight all the way to Mars.
  • Riding photons through space may sound like fiction, but it's science.
  • Scientists are currently exploring how the use of lasers and thinner, lighter materials could open up new possibilities.
  • Even now, there's a toaster-sized spacecraft orbiting the Earth by solar sail.
  • While solar sails that could propel a ship as massive as Sojourner aren't reality just yet, a future of space exploration fueled by the sun is certainly a powerful idea.
