Science fiction spaceships, travel to other planets, Star Wars, Star Trek - in my opinion, this series can very well be complemented by the word laser. But instead of destroying spaceships or entire planets with lasers, you can actually use lasers to propel spaceships. With laser propulsion, there is actually already a technology today with which we would basically be able to send probes to neighboring stars like Alpha Centauri within a generation. And that's exactly what NASA and a private initiative launched by Stephen Hawking and Mark Zuckerberg want to do.
The idea for today's video came to me through a cooperation with Andreas from Yggis Kosmos: • Doku: Interstellare An... On his channel you can find a video about interstellar future propulsion, in which I participated with a short intermezzo about laser-based photon sails. Have a look! Andreas channel Yggis Kosmos : / @yggiskosmossterneundu...
My video today is about different concepts that use lasers to power spacecraft, and how lasers work.
