Frequently Asked Questions
What period does the history cover?
It starts with how ancient astronomy and centuries of imagined voyages set the cultural stage, then covers early rocketry, the Space Race, Apollo, stations and the Shuttle, the ISS partnership and the commercial era.
Does it cover Japan's space program?
Yes, in a bonus module: ISAS and NASDA before their 2003 merger into JAXA, Japan's first satellite Ohsumi, and the two Hayabusa asteroid sample-return missions.
What was Sputnik and why did it matter?
Sputnik, launched by the USSR on October 4, 1957, was the first artificial satellite: a simple radio-beeping sphere. It mattered because the rocket that launched it was an ICBM-class booster, proof of a capability that directly tied to nuclear strike fears and triggered a US policy panic.
Who was the first human in space?
Yuri Gagarin, aboard Vostok 1 on April 12, 1961. He completed a single orbit of Earth in under two hours.
Is it free, and do I need an account?
Yes. The lessons are free and open to read without an account. There is no accreditation or certificate attached: it is a self-directed curriculum built from primary sources.
How long does it take?
Each module is sized for one sitting, and the module pages estimate 25 to 35 minutes each. All of the modules on this page add up to about 4.2 hours of reading.
