It COULD be achievable within our lifetime! But, how would an interstellar rocket-ship work? On this week's episode of Space Time, Matt talks options for interstellar travel - from traditional rocket fuel to antimatter drives, could we travel to other star systems?

The final question for Dr. Tyson's Lecture/Q&A at Millett Hall, Miami University.

Is Time Travel Really Possible?

We've all wondered at some point whether time travel is actually possible like it is in the movies. Second Thought is here to find out!

Voyager 1 & 2 UPDATE-Where Are They?+ Brief Mission Recap (Short Version)

Begins with a brief recap of the Voyagers mission then describes the probes current location, what they are finding, and what their future holds. For full long version please click this link. https://youtu.be/IS-P8mkGLS4 www.carolmeiervoiceover.com

SLAM - America's Big Stick & Doomsday Weapon

Just before ICBM's became the de facto delivery system of choice, the US created what could be called the doomsday weapon of the cold war. It was deemed so dangerous that the same government that commissioned it, cancelled it before it went into production. This is the story of Project Pluto and SLAM the unstoppable nuclear-powered cruise missile it created.

Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light?

This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default.

For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive is left out until it's proven with actual reproducible results in space.

Project Daedalus and the updated Project Icarus represent sound concepts for fusion spacecraft. IKAROS was the first successful demonstration of solar sail technology but hopefully the planetary society is not far behind with their LightSail cubsat (not covered in this video).

But what appears to have the most potential to reach the nearest star to our own, Proxima Centauri and it's newly discovered planet Proxima b is Breakthrough Starshot. Thousands of super lightweight laser sail nanocraft will be launched into space then the light beamer, a ground based laser array will propel these spacecraft to 20% light speed within minutes.
