Why Launch Solar Panels When You Can Print Them Directly In Space? Printing Perovskite Panels

solar energy is the ideal way to power a spacecraft there’s no weather there’s no pesky atmosphere just pure photons streaming from the Sun to harvest for whatever you need well as long as you’re within the inner solar system but solar panels are complicated and fragile made of sensitive electronics and glass and not […]

Surviving On Venus. Is It Time To Go Back To That Awful Place?

if you’ve watched this channel enough you might get the impression that I hate Venus it’s possible just possible that I’ve even suggested that the planet is so terrible it should be pushed into the Sun the reality of course is that it’s an incredibly fascinating world the closest twin to the earth that we […]

Earth To Mars In 100 Days? The Power Of Nuclear Rockets

The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets. Of course, launching a rocket powered by radioactive material has its own risks […]

Can We Launch Nuclear Waste Into the Sun? Why This is a Terrible Idea

When I look at the Sun, I don’t see a warm life-giving orb, nourishing all living creatures here on Earth. No, I see that fiery ball as a cosmic garbage compactor. A place I can dump all my household garbage, to make room for new impulse purchases. I mean, the Sun is right there, not […]

How Do Ion Engines Work? The Most Efficient Propulsion System Out There

People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do? Good news, there are other, exotic science fiction-sounding propulsion systems out there which use electromagnetic fields to accelerate atoms, allowing their spacecraft to accelerate for months at a time. I’m talking […]

A Spacecraft Is Going To Build Its Own Solar Panels In Space: Archinaut One

As I’ve mentioned in several episodes now, humanity is in a bit of a transition period, a time when it makes sense to launch material up and out of Earth’s gravity well into orbit, and beyond. But it’s really expensive, costing up to $10,000 per pound you want in orbit, and 10 times if you […]

The Problem of Power in Space. NASA’s New Kilopower Reactor

Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention all the power to run scientific instruments and the transmitters to send that […]
