10/18/2019
More
In this week's questions show, I explain why we'll never know which stars have no planets. How we could prevent a catastrophe to Earth, and why aliens might still be a threat to us.

Episode 578: Open Space 49: How Can Planets Capture Asteroids? And More...

10/15/2019
More
No guest this week, just a live QA with me and the audience about all things space and astronomy. People had questions about how planets can capture asteroids to turn them into moons, what rocket James Webb will use to fly to space, and why you can't use antimatter to destroy a black hole. 05:45 How can a planet capture an asteroid? 07:21 Why are quasars so far from us? 09:26 How could you make a black hole of photons? 11:25 Would I rather live a year on the Moon or Mars? 12:46 What will...

Episode 577: AstroClipper: Plans For A Two-Stage, Fully Reusable Spaceplane

10/15/2019
More
Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again. Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what...

Episode 576: What Comes After LUVOIR? Three Extreme Ideas For Space Telescopes

10/11/2019
More
While we’re all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved. (Please get approved, please get approved.) We’re going to need a way to pass the time. So let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes. Unless you’ve been crawling through scientific journals like me, I guarantee you’ve never heard of any of them. But when I’m...

10/11/2019
More
In this week's questions show, I explain why Starship probably won't contribute to human carbon emissions, if there's a galactic Prime Directive, and if SpaceX has finally perfected the single-stage to orbit. Featuring Tony Darnell from Deep Astronomy and the Space Junk Podcast https://www.youtube.com/user/tdarnell https://optcorp.com/blogs/podcast 00:30 Won't Starship cause global warming? 02:33 Do we live in a Galactic Zoo? 04:45 Has SpaceX perfected SSTO? 07:17 How will Starship's thermal...

Episode 574: Venus Could Have Supported Life For Billions Of Years. First Habitable Planet In The Solar System?

10/10/2019
More
After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more. But was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally...

Episode 570: What Will It Take To Feed A Million People On Mars?

10/1/2019
More
In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects it’ll take to create a self-sustaining civilization. The number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement...

Episode 571: Starship Takes Shape. Are We Months Away From A Fully Reusable Rocket System?

10/1/2019
More
On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel. As part of his presentation, Musk showed off the history of the company’s developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when they’re fully operational. It was actually a pretty short presentation, and there weren’t a...

Episode 569: Open Space 46: Dr. Robert Zubrin and the "Case for Space"

9/27/2019
More
One of my most requested guests is Dr. Robert Zubrin, engineer and founder of the Mars Society. It was Dr. Zubrin's "Case for Mars" that helped inspire me to get into space journalism in the first place. We had a wide-ranging interview that updated the Case for Mars, looked at what comes next, and how current efforts are stumbling in their efforts to return humans to the Moon, and then on to Mars.

This week I was joined in a livestream with Dr. David Kipping from Columbia University. We had a great interview about his research into exomoons, what new observatories will do for this field. We also talked about his idea of the Terrascope, using the Earth's atmosphere as a lens to study the Universe. And we talked about how scientists can better use the internet to communicate directly with the public about their research. Subscribe to Dr. Kipping's YouTube Channel here:...

Episode 566: Better Than Earth? Are There Superhabitable Worlds In The Milky Way?

9/23/2019
More
I’ve said many times in the past that the Earth is the best planet in the Universe. No matter where we go, we’ll never find a planet that’s a better home to Earth life than Earth. Of course, that’s because we, and all other Earth life evolved in this environment. Evolution adapted us to this planet, and it’s unlikely we could ever find another planet this good for us. However, is it the best planet? Are there places in the Universe which might have the conditions for more diversity of life?...

Episode 563: Want To Explore Mars? Send Humans To The Moons Of Mars First: Phobos And Deimos

9/17/2019
More
Humans to Mars. That’s the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. It’s a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least. But there are two places humans can go which are a stepping stone between Earth and Mars. Base camps that would let us gather our resources in relative...

Episode 561: Water Vapor Seen In the Atmosphere Of An Exoplanet. It Might Even Be Rain

9/13/2019
More
We’re learning more and more about extrasolar planets, and for the first time, astronomers have discovered water vapor in the atmosphere of a planet orbiting another star. The planet is located in the habitable zone of its star, so this might even be rain. Of course, it’s not all good news, it’s much more massive than Earth, with higher gravity, and is probably bathed in radiation from its red dwarf star. But, it’s a good start in the search for habitable places in the Universe, places where...
