Just assigned ISBNs and requested Library of Congress numbers for the paperback and ebook versions of the forthcoming book. Things are finally getting real.
Illustration for next book
Illustration for the next Generation Mars book is coming along nicely. Here’s a sample.
This is what Cas sees from inside her helmet as she walks through a dust storm. Note the cool head-up display. (great work by Luis Peres)
Areography
Atlas Pro has created a really cool video on areography–the “geography” of Mars. It’s a brief but thorough survey of the surface of Mars and well worth a watch.
I really want a print of the map presented at 3:00.
Starship SN-5 successful hop!
Thanks to Everyday Astronaut for the coverage and the contagious enthusiasm.
Lots of space stuff going on!
I’ve been a little caught up in day-to-day living and not posted anything about all the cool stuff going on in space right now.
Mars is getting new robots!

And Endeavour is bringing Bob and Doug home this weekend!
Audiobook available!
At long last, the audiobook version of Scratching the Surface has been approved and is now available. Read by Emily Lakdawalla, Senior Editor and Solar System Specialist for The Planetary Society, the audiobook includes a downloadable pdf containing illustrations and background material.

Fire from space
The Bighorn Fire has been burning in the mountains near Generation Mars HQ for almost a month. You can see the edge of the city along the bottom and left sides of this image.
It’s an interesting experience to watch a DC-10, flown like a crop duster, painting orange stripes across your mountains, as smoke from the fireline advances toward your city. This satellite image really brings home just how massive this fire is.
How many people?
This is an interesting paper estimating the minimum number of people required for a self-sufficient colony on Mars. Using a mathematical model to estimate work time requirements vs. work time capacity, the researchers come up with a surprisingly low number: 110.
In the forthcoming second book of the Generation Mars series, I peg the colony population at around 5000, so I think I’m good there.
Nature Lightning
A new study suggests lightning may be weak or nonexistent in Martian dust storms. Researchers vibrated basalt grains at various atmospheric pressures to test their ability to build up charge.
Lightning in a dust storm plays a role in my forthcoming book, Air: Generation Mars, Book One. Hard science fiction is a moving target. Still, the fictional strike in question is weak and only damaging to electrical equipment, so I think it’s plausible.
Launch day
In about two hours, if the weather allows, SpaceX will be launching two astronauts in a Crew Dragon capsule to the ISS for the first time. This is a big deal.
Nine years ago, I watched the last shuttle launch with my kids. The oldest was three years old, and the other was one, so they have no recollection of this. Since then, they have grown to awareness in a world in which the US is incapable of launching its own astronauts into space.
This launch means that will now change. But this launch goes beyond just returning human-launch capability to US soil. That’s cool and all, but focusing on it is a bit short-sighted. This launch marks a turning point in humankind’s relation to space.
SpaceX, with its rapid development of Cargo Dragon, Falcon 9, and Falcon Heavy, has managed to decrease the cost of getting things to space by orders of magnitude. When it is possible to launch lots of stuff cheaply, we’ll launch lots of stuff. Now, with Crew Dragon, SpaceX is going to do that for humans. And when it becomes possible to launch lots of humans cheaply, we’ll launch lots of humans.
Lots of humans and lots of stuff in space means, well, it could mean anything. But mostly, it’s a critical step toward becoming a space-faring civilization. And that’s why this is a big deal.
