| 0:00.0 | Hello, SFIA audio listeners. |
| 0:02.5 | In this month's Nebula exclusive, big alien theory, |
| 0:05.2 | we're asking the reason alien civilizations might be rare is because most aliens are huge. |
| 0:10.5 | To hear it and every episode early and ad-free, plus hours of bonus content, |
| 0:15.1 | check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur. |
| 0:21.0 | The red planet beckons us toward it, and the day draws closer when humans will walk on its dusty surface, |
| 0:27.7 | and the moons of Mars may be our gateway to that future. |
| 0:33.9 | Today we are taking a look at the two Martian moons, Phobos and Demos, named after the |
| 0:38.8 | horses that drew the god of war's chariot, and as we'll see, they could potentially play |
| 0:43.9 | a critical role in transport to and from Mars, in keeping with their mythological namesakes. |
| 0:50.6 | Probably the two biggest differences between Mars and the Moon, for the purposes of visiting |
| 0:54.6 | exploring them, are how long it takes to get there, and how much harder it is to get back |

| 1:00.5 | The Moon is more than an order of magnitude further away from Earth than any place on Earth |
| 1:05.2 | is from another, but Mars is too more beyond that, moving for a quarter of a million miles |
| 1:10.7 | away to more like |
| 1:11.7 | a hundred. Neither has much gravity compared to Earth, but Mars has more. It also has a scanty |
| 1:18.8 | atmosphere, just enough to make landing there cheaper in fuel than on airless place, and also |
| 1:23.7 | a bit of a pain to get off of. This is our core issue today, because Mars is so far from Earth that any mission sent there |
| 1:30.9 | is out of luck for a supply and needs to hang out there for many months, not days like the |
| 1:36.6 | moon missions. |
| 1:37.8 | But so long as a mission has access to power and water, it can't basically keep going |
