Future of Interstellar Travel

Space – I came across the article “Here Is the Future of Interstellar Spacecraft” yesterday and thought it was a good overview of the propulsion technologies that are likely to take future spacecraft beyond the Solar System.

In short the alternatives that are covered are:

  1. Thermonuclear propulsion
  2. Lightsail
  3. Bussard ramjet
  4. Antimatter rockets
  5. NASA’s Eagleworks Lab “Warp bubble” drive

None of these are really going to be ready in the near future, with possibly the exception of the Lightsail. I am glad to see though that the ideas are being kept in front of people, particularly those budding STEM students who will lead the way over the next few decades.
