I missed some interesting news a couple months ago, and I'm guessing you did, too. The launch of China's Tianwen-2 on May 28 took place without much fanfare. Just one space probe among many. Except, it isn't—China is flexing its muscles with an ambitious two-in-one mission, which will not only expand the nation's scientific knowledge... Continue Reading →
Michael Collins: The Man Who Didn’t Walk on the Moon
56 years ago today1, Apollo 11 made the first manned landing on another world. Ask the average American about it, and they'll likely be able to name the mission's commander, Neil Armstrong, who famously made his “one small step” speech as he climbed out of the Lunar Module Eagle; they might also remember Edwin “Buzz”...

Book Review – Extraterrestrial (Avi Loeb)
Avi Loeb believes aliens are real, and they've visited our Solar System. But this man is no fringe conspiracy theorist, dressed in ratty flannels and a tinfoil hat, broadcasting rants from a pirate radio station in the wilderness—he's a Harvard University professor, who has done world-renowned research on cosmology and astrophysics. This is a serious... Continue Reading →
The Moons, Ranked
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 →
The Planets, Ranked
Not all the worlds in our solar system are created equal. Some are enormous, some are vanishingly small; some are scorching hot, others freezing cold; some (one) are clement to human life, while some (all the rest) are inhospitable deathtraps. And if I may be frank---some are just better than others. For today's post, we... Continue Reading →
Apollo 18, 19, and 20: The Moon Missions That Weren’t
Some of you may remember my previous posts about secret Apollo missions: Apollo 18, the ill-fated landing which fell victim to rock spiders, and Apollo 20, a joint US-Soviet effort which recovered a living alien from the far side of the Moon. Both are fictional, of course. One is a horror movie, the other a... Continue Reading →
Russia’s Troubled Decade in Space
The 1990s were not a good time in the former Soviet Union. When the central government fell, it wasn't just a political collapse, but a collapse of just about everything---the military, the economy, society itself. Ethnic tensions erupted into raging civil wars; rushed free-market reforms threw countless millions into poverty; amid political turmoil, President Boris... Continue Reading →
Explorations in Old Space Books
Very early on, my family instilled in me a love of coffee table books: hefty, hardcover volumes, large enough to double as paperweights or even footstools1, bedecked with photographs and artwork from front to back. Instead of reading straight through, you could open one to whatever page you fancied. They covered all sorts of topics,... Continue Reading →
Luna 3: First to the Far Side
It was on October 7, 1959, that the dark side of the Moon finally came into the light. Mind you, it was never "dark" in a literal sense; all parts of the Moon undergo a complete day/night cycle, with the far or "dark" side being lit when the near one is in shadow, and vice...
