DESCENT
A FIELD GUIDE TO LUNA & THE MOON RACE

Ten chapters on the two very different strategies — one robotic, one crewed — that two nations used to reach the same 384,400 kilometres, and on the new race now heading back to the same coordinates. Scroll to begin the mission.

BEGIN — CHAPTER 01
CH.01 / 10ESCAPING TO THE MOON

Not quite escape velocity — just enough

A spacecraft bound for the Moon doesn't need the full second cosmic velocity — it only needs enough speed to raise its orbit until the Moon's own gravity takes over. That threshold sits close to 10.9–11.0 km/s from a low parking orbit: comfortably above first cosmic velocity, just under full Earth escape.

Adjust the trans-lunar injection burn below and see where the same spacecraft ends up.

CH.02 / 10THE LUNA PROGRAM

Twenty-four missions, five firsts

Between 1959 and 1976, the Soviet Union flew 24 uncrewed Luna missions — 15 of them successful — and claimed nearly every early lunar milestone before a single human ever left Earth orbit. Scrub through the program.

CH.03 / 10APOLLO & THE RACE

Six landings, twelve boot prints

Where the Soviet Union sent machines, the United States sent people. Apollo 11 landed the first crew on July 20, 1969; five more landings followed through Apollo 17 in December 1972, each carrying more science and staying longer than the last.

CH.04 / 10LANDING ON THE MOON

A robotic lander, taken apart

Luna 16, the first robotic sample-return mission, combined a landing stage, a drill, and a small rocket-powered return capsule in a single spacecraft. Select a component.

CH.05 / 10LUNOKHOD — THE FIRST ROVERS

Driven from a room in Crimea

Lunokhod 1 landed with Luna 17 in November 1970 — the first robotic rover on another world, driven in real time by a five-person crew on Earth watching a slow-updating video feed. Lunokhod 2 followed in 1973 and drove 42 kilometres, a distance record that stood for over four decades. Select a part.

CH.06 / 10TWO STRATEGIES, ONE GOAL

Send a person, or send ten machines

Neither approach was cheaper or safer in any simple sense — each traded one kind of risk and cost for another.

CH.07 / 10BRINGING THE MOON HOME

Grams against kilograms

Three Luna missions drilled and returned lunar soil entirely without a crew; six Apollo missions carried astronauts who could choose, by eye, which rocks were worth the weight.

CH.08 / 10THE FAR SIDE AND THE POLES

The two places nobody had seen

CH.09 / 10LUNA 25 AND THE NEW RACE

Half a century later, back at the pole

Figures below reflect the state of active programs as of mid-2026; schedules for crewed and robotic lunar missions shift often, so treat dates as current plans, not fixed facts.

CH.10 / 10LEGACY

From Luna 1 to whoever lands next

Every lunar program since has stood on this one's shoulders — including the robotic and crewed missions now heading, once again, toward the poles.
