Asteroid mining economics: start with the 121.6 grams
The best-funded asteroid sample return in history brought back about a quarter pound. Here's what that tells you about metal-asteroid pitches.

Nobody is hiring 'space miners.' Plenty of companies are hiring the people who will build the machines. What we see on our own jobs board.

Seventy-seven countries have signed a non-binding document about the Moon. Two sections matter if you plan to dig.

Lunar helium-3 has signed customers now. They want it for quantum fridges, not fusion. Here's what's contracted and what isn't.

Find it, dig it, cook it, use it. The chemistry has been demonstrated. Prospecting is the bottleneck.

In-situ resource utilization, explained from the mass budget up. Start here if you read nothing else.

What Moon soil is made of, why it's mostly oxygen by weight, and what makes it miserable to handle.

Martian soil is chemically more interesting than the Moon's and also more hostile. Here's what the landers found.

A side-by-side comparison of the three frontiers on distance, feedstock, demonstrated hardware and who's paying. Our pick, with reasons.

Where the Moon's ice is, how we know it's there, and the one unknown that decides whether it's worth mining.

122 grams of oxygen on Mars, read carefully. The scale-up gap from a toaster-sized demo to a propellant plant.

The 1967 Outer Space Treaty, the 2015 U.S. Commercial Space Launch Competitiveness Act and the Artemis Accords, read in order.

What 100-plus tonnes to orbit really buys on the lunar surface, why refilling is the whole game, and the per-kilogram number to watch.

A working map of the companies and agencies with hardware, contracts or customers. If it's only a rendering, it isn't on the list.

We counted every open posting at 11 space companies. About 2.6 percent had AI or machine learning in the title. Where they are and how to get one.

Most of the jobs on a rocket company's board aren't titled 'aerospace engineer.' Which degrees and backgrounds map onto them, and how to prove it.

Coming from another industry? Map what you already do onto a job these companies post, close one gap with one project, and skip the second degree unless a rule requires it.

A short list, checked against what the jobs ask for: MIT OpenCourseWare, the official ROS 2 tutorials, NAR rocketry certification and the FAA mechanic route.

NASA OSTEM and Pathways, SpaceX and Blue Origin, the Brooke Owens and Patti Grace Smith fellowships, and the Isakowitz scholarship. What's open, what closed, and who qualifies.

Why so many aerospace postings ask about citizenship, who actually qualifies, and what non-citizens can still apply for.

The four kinds of robotics jobs that are actually hiring, the free material that teaches the core stack, and how a planetary rover career usually starts on Earth.

Three project types that hardware recruiters recognize, how to scope each so you actually finish, and what to write up afterward.

A map of the 32 companies on our jobs board by field and city. Southern California and the Bay Area dominate. Here's the rest.
