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.

QA 52: Could Satellites With Lasers To Clear Debris Be Weapons Too? And More...

Thu, 12 Apr 2018 00:12:00 PST

In this week's questions show, Fraser explains how space debris hunting satellites could also be used as weapons, why his green screen is always set to Endor, and ways to find nearby places for stargazing.

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.

QA 51: Could We See Ourselves in the Past? And more..

Thu, 29 Mar 2018 00:12:00 PST

In this week's QA, I wonder if we could use the speed of light to see ourselves in the past, how the Mars rovers clean their solar panels, and if aliens would infect us with their bacteria and viruses.

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?

346: Which Are The Real Pictures of Space? What’s a Photo and What’s An Illustration?

Wed, 21 Mar 2018 00:12:00 PST

With modern computer graphics, it’s sometimes hard to know which is an actual photograph of space, and what’s an illustration or a 3D rendering. Some really fascinating discoveries don’t have a pretty picture to go along with them, so illustrations are created to help us understand.


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.

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

Fri, 09 Mar 2018 00:12:00 PST

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.

Tue, 13 Feb 2018 00:13:00 EST

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.

Tue, 14 Nov 2017 00:53:12 +0100

In order to get the large scale structure of the Universe we see today, cosmologists have proposed the idea of inflation, that the Universe expanded an enormous amount in the earliest moments. But if inflation really happened, then it has even stranger implications for the nature of the Universe and the search for multiverses.
