Back in February I handed down the definitive ranking of all the planets in our Solar System. Today, I'm going to finish the job with a corresponding ranking of the Solar System's moons—rich and varied worlds in their own right, some larger than the smallest planets. This will not be an exhaustive list. Jupiter alone... Continue Reading →
Book Review – The Case for Space (Robert Zubrin)
Robert Zubrin is a persistent man. An engineer, author, and above all, space advocate, he's lobbied for a human voyage to Mars for about three and a half decades now, even as the US government has dilly-dallied its way through various questionable exercises in pork-barrel spending. It's 2025 and human boots haven't even returned to... Continue Reading →
Book Review – How to Mars (David Ebenbach)
How to Mars is like Andy Weir's The Martian, if The Martian had been written by a humanities major instead of an engineer. It is also, not coincidentally, a better book. Now, the subject of today's review was something of a happy accident on my part. I was at my local library---the same library where... Continue Reading →
Book Review – A Princess of Mars (Edgar Rice Burroughs)
Ah, to live in the old Solar System, before our nosy little space probes pushed back the veil and revealed the other planets to be absolute shitholes. Venus was, beneath its clouds, a steamy paradise world full of lush vegetation and primordial beasts; Mars, meanwhile, was one vast desert crisscrossed by canals, pockmarked by the...

Secrets of the Valles Marineris
The first and only time I ever saw the Grand Canyon was when I was eight years old, traveling through the southwestern United States on a family road trip. I knew roughly what it looked like, of course, but nothing had prepared me for the sheer scale of that thing. It was a sculpted, dizzyingly... Continue Reading →
The Star-Spangled Cosmos: America’s Exceptional Future in Space
Happy Fourth of July, everyone! I have a special post for y'all, in the patriotic spirit of this great holiday. Right now, we're at a critical juncture in space history---any month now, we're supposed to see SLS and Starship take flight, after many years of waiting---and it's clear that there's a different energy in the...

Sci-Fi Film Review – The Angry Red Planet (1959)
One afternoon in tenth grade, when I was home sick with a nasty cold, I curled up beneath some blankets and watched an old 1950s sci-fi movie about a mission to Mars. I ended up drifting in and out of consciousness through most of it. Afterwards, I only recalled bits and pieces, but the images... Continue Reading →
Cradle of Humanity
A think piece for today: If you want to get a rise out of space nerds, bring up Mars colonization1. These days it's the subject of countless op-eds and heated Facebook discussions. The Elon Musks and Robert Zubrins of the world are fierce proponents, viewing the expansion of humanity as a matter of survival; on... Continue Reading →
The Decline and Fall of Mars One
Sometimes, the underdog really does win against the odds. Sometimes, a small, plucky band of visionaries, armed only with a dream, really can rise to dizzying heights and reshape the world into something better. Sometimes, their success is so profound and transformative that later generations think it was inevitable all along. Mars One was not... Continue Reading →
TMK-E: The Nuclear Mars Train
Last week I posted a review of the 1963 film A Dream Come True, about a Soviet expedition to Mars, and today I'm going to share the Mars mission the Soviets were actually planning when that movie came out. It was... ambitious, to say the least. "Nuclear-powered Mars train from pole to pole" levels of ambitious.... Continue Reading →
