Episode 425: QA 56: Is Everything We See Long Dead? And More...

When we look out into space, are we really just seeing stars, planets and galaxies which are long dead, ghosts from eons ago? Can black holes consume dark matter? Can we repair Kepler and other dead satellites, and more. Support Universe Today Podcast

Episode 416: Open Space 1: Live QA on YouTube

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.

Episode 415: 349: Farewell Kepler. Welcome TESS And The Quest To Find Earth 2.0

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.

Episode 413: 348: Living Underground on Other Worlds. Exploring Lava Tubes

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: ...

Episode 411: 347: Searching for Life on Europa? Going Under the Ice

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? Support Universe Today Podcast

Episode 407: 345: What Will It Take To Make Artificial Gravity? Surviving in Space Forever

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.

Episode 406: QA 48: Is Falcon Heavy More Powerful Than Space Shuttle? And More...

In this week's QA, I compared apples to apples and look at the launch capability of the Falcon Heavy versus the Space Shuttle. The answer may surprise you. We also look at extracting energy from a black hole, and if launching satellites from the Earth's poles will avoid a Kessler Syndrome. Support Universe Today Podcast

Episode 399: 341: The Rocket Engines Carrying Us to Space. The SLS RS-25 (aka The Space Shuttle Main Engine)

There are few rockets more iconic than the RS-25, also known as the Space Shuttle main engine. Even though it’s been around in some form since the 1970s, it’s been improved and upgraded several times, making it the most efficient liquid fuel rocket engine going today. And now the RS-25 is going to see a new chapter in its history, working to carry NASA’s new Space Launch System back to deep space, beyond Earth orbit. Support Universe Today Podcast...
