Open Space 1: Live QA on YouTube

Wed, 18 Apr 2018 00:12:00 PST

Once a week I'll be opening up the livestream on my YouTube channel and taking questions from the audience, as well as inviting special guests to join me. I didn't think about turning into this into a podcast, so I apologize. Next time I'll be more careful about making sure I read out the questions carefully for audio listeners.

349: Farewell Kepler. Welcome TESS And The Quest To Find Earth 2.0

Tue, 17 Apr 2018 00:12:00 PST

We’re now entering the final days for NASA’s Kepler Space Telescope. It’s running out of fuel and already crippled by the loss of its reaction wheels. In just a few months NASA will shut it down for good. That is sad, but don’t worry, NASA’s next planet hunting spacecraft, the Transiting Exoplanet Survey Telescope is on the launchpad and ready to fly to space to take over where Kepler left off. Finding Earth-sized worlds in the Milky Way.

348: Living Underground on Other Worlds. Exploring Lava Tubes

Wed, 11 Apr 2018 00:12:00 PST

The Moon and Mars will probably be the first places in the Solar System that humanity will try to live after leaving the safety and security of Earth. But those worlds are still incredibly harsh environments, with no protection from radiation, little to no atmosphere, and extreme temperatures. Living on those worlds is going to be hard, it’s going to be dangerous. Fortunately, there are a few pockets on those worlds that’ll make it a tiny little bit easier to get a foothold in the Solar System: lava tubes.

Media Files:

347: Searching for Life on Europa? Going Under the Ice

Tue, 27 Mar 2018 00:12:00 PST

We’re now learning that icy worlds seem to be the best places in Solar System where life could be hiding. Worlds like Europa and Enceladus, which have vast oceans of liquid water beneath a shell of water ice. Clearly we need to explore these worlds, to go deep down beneath the ice to explore the ocean depths. But how do you drill through kilometers of ice to reach it?

Media Files:

345: What Will It Take To Make Artificial Gravity? Surviving in Space Forever

Wed, 14 Mar 2018 00:12:00 PST

If we want to live and work in space for long periods of time, we’ll need to conquer the lack of gravity and its effects on the human body. We’ll want to come up with some kind of artificial gravity. Futurists imagine huge rotating space stations, but realistically there are strategies that could provide artificial gravity for the times that we need it, and allow us to survive in space forever.
