Summary

PREVIEW. Nuclear Propulsion, Russian Cruise Missiles, and the Future of Flight on Mars. AJ Kulhari of Astrix Corporation discusses a nuclear-powered rocket concept that generates thrust by heating intake air or other material. Russia successfully tested such a cruise missile that can fly low around the world. This same method could work on Mars, using its abundant carbon dioxide atmosphere as the substance to heat. This could allow a vehicle to travel completely around Mars using only 20 grams of fuel.

This is John Batchel. Conversation with A.J. Colhari of Astrox Corporation about a rocket that is powered by a nuclear power energy source.

0:13.6

The way it goes is it takes air in and heats it and then that turns into the thrust at the aft of the missile.

0:23.6

Russia has now successfully tested such a missile.

0:27.2

Borevznik, a cruise missile that can fly around the world with very little fuel, very low.

0:33.8

However, I learned from A.J. Colhari, this same method would work on planet Mars, even with its thin atmosphere.

0:42.6

Here he describes how.

0:45.3

All it needs is something to heat and make into thrust, and on Mars there's abundant carbon dioxide in the thin atmosphere.

0:54.9

AJ Colerre on the future of travel, flight on the planet Mars.

1:00.9

Well, a little off of it, say a thousand feet or so, where the air is thickest.

1:07.7

More of this tonight.

1:10.1

And it's flying on Mars.

1:12.0

Now, Mars has atmosphere.

1:15.1

It's mostly CO2.

1:16.5

But it's atmosphere.

1:17.3

We're not burning anything.

1:18.5

There's no combustion here.

1:19.9

So it doesn't matter if you don't have any, you know, oxygen or anything like that there.

1:25.8

But you have to have something.

1:27.4

You have to have something to heat that.

1:29.3

Basically, the idea is to heat something enough and propel it in the back so that it

1:35.3

becomes, you know, it creates stress.

1:38.3

You can do that on Mars.
