Let's Get Off This Rock Already!
Musings on space travel, science fiction, and the radiant future
A couple weeks ago, I wrote a piece on the next steps for American space travel, and speculated about a permanent lunar base within the next two decades. Today I have another guest post from my friend Eamon Minges, following up on my speculation with some hard numbers---he definitely has a knack for that sort... Continue Reading →
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...

Nuclear power has had a long and complex history in outer space. Starting in the 1960s, both the US and USSR deployed full-on fission reactors aboard Earth-observing satellites; more recently, high-profile probes---Cassini, Curiosity, New Horizons---have all used safer but far less powerful radioisotope thermoelectric generators (RTGs), which extract energy from the waste heat of decaying...

When I was young, Ceres and Pluto were the biggest blank spots on the map of the Solar System. Most of the other interesting places had been long since explored, from Mercury all the way out to the moons of Neptune, but when I opened my astronomy books to the two minor planets, I saw...

I originally had another topic planned for today---it was written and scheduled, and of course I will still upload it at some point---but then my area had a rare winter storm, blanketing everything in ice and snow, and I thought to myself that it would be appropriate to do a blog post on Europa, one...

Another short post this week1. Today, we will be exploring what has become a common theme on this blog, or rather a common destination: Neptune. Neptune is indisputably the Spooky Planet. If the Solar System had a haunted house, this would be it---a cold, dark, storm-wracked world made extra fascinating by its sheer remoteness. Only... Continue Reading →
A couple posts ago, I reviewed a book about an expedition to Titan---arguably the most interesting celestial body in the Solar System---and I'd like to continue in that theme this week, turning my attention to a real, official Titan exploration project under development at NASA: the Dragonfly mission. Dragonfly will be a quadcopter aircraft sent... Continue Reading →
Oddball mission studies are my jam. Sometimes, they are NASA's jam, too---the agency is not afraid to occasionally explore the more speculative topics, spacecraft which rely on advanced technologies and are many decades away from ever seeing implementation. I stumbled across one such study when I was doing some reading on Pluto the other day.... Continue Reading →
After decades of messing around in low Earth orbit, and several false starts (I shed a tear for Project Constellation), the 2020s may finally be a spaceflight renaissance. NASA's always-ambitious plans are now backed up by real, concrete progress in the private space sector. SpaceX has a feasible roadmap to go to Mars, though the... Continue Reading →
Somewhere between the current human presence in the space—zilch, save for three people aboard the ISS—and the most ambitious, wide-eyed, optimistic visions for colonization—Musk's million people on Mars, Bezos' trillions throughout the solar system—there's a middle ground where we work on and explore other planets, but inhabit them only in the same sense that we...
