A History of Spaceflight

The history of spaceflight starts not in a cleanroom but in a Baltic forest. In October 1942, a German A-4 ballistic missile — soon renamed the V-2 — climbed to an altitude of about 84 kilometres on its third test flight from Peenemünde, becoming the first object built by human hands to cross what we now consider the boundary of space. The vehicle was a weapon, designed to deliver a one-tonne warhead to London at supersonic speed; the engineering breakthroughs that made it work — gimballed exhaust, regenerative cooling, inertial guidance — became the entire foundation of the rocketry that followed.

When the Second World War ended, the people who had built the V-2 became one of the most aggressively pursued resources of the early Cold War. The United States smuggled Wernher von Braun and roughly 1,600 other German scientists out under Operation Paperclip and put them to work in Huntsville, Alabama. The Soviet Union pulled in a smaller cohort and a much larger pile of hardware. Both programs spent the next decade quietly turning what had been a terror weapon into the basis of a civilian space program — and a parallel intercontinental nuclear-delivery system.

By 1957 both superpowers had heavy lift vehicles flying. The Soviets were ahead and they knew it; the world was about to find out.

On 4 October 1957, an R-7 rocket lifted off from Tyuratam in Kazakhstan carrying a polished aluminium sphere about the size of a beach ball. Sputnik 1 weighed 84 kilograms, transmitted a simple beep on two radio frequencies, and orbited the Earth 1,440 times before re-entering. The political effect was wildly disproportionate to the spacecraft itself: the United States, which had assumed it was the world's pre-eminent technological power, suddenly discovered it was second.

What followed was the most concentrated period of progress in the history of any technology. In a single decade humanity went from being unable to put anything in orbit to walking on the Moon. The cadence of "firsts" between 1957 and 1969 is almost incomprehensible: first satellite, first animal, first human, first spacewalk, first orbit of the Moon, first soft landing — every milestone fell in less time than it now takes to develop a new launch vehicle.

The race was as much about institutional design as engineering. NASA was founded in 1958 as a deliberately civilian agency with the explicit goal of separating spaceflight from military operations. The Soviet program kept its civilian and military branches tangled, which gave it speed but cost it the institutional memory it needed when its chief designer Sergei Korolev died unexpectedly in 1966. By the time Saturn V flew, the Soviets were three steps behind; by the time Eagle landed in the Sea of Tranquility on 20 July 1969, the race was effectively over.

Apollo 11 was both a peak and a turning point. By 1972, public interest had cooled enough that Apollo 17 — still the last crewed mission to leave low Earth orbit — landed and returned with little of the live-television fanfare of its predecessors. NASA's budget, which had peaked at over 4 percent of federal spending in 1966, was on its way to the under-1-percent floor it has occupied for the past forty years.

But what looked like retrenchment from the outside was, in engineering terms, one of the busiest decades in the history of spaceflight. The Soviet Union, having effectively conceded the Moon, pivoted to long-duration crewed flight and put the world's first space station — Salyut 1 — in orbit in 1971. The United States flew Skylab, retired Apollo, and started bending metal for the Space Shuttle. Both superpowers fielded a fleet of robotic probes that visited every planet in the inner solar system and started reaching the outer worlds. Mariner 9 became the first orbiter of another planet. Pioneer 10 and 11 punched outward through the asteroid belt. Voyager 1 and 2 launched in 1977 on what was supposed to be a four-year tour and is, as of 2026, still returning data from interstellar space.

By the end of the decade the United States had not flown a crewed mission in nearly six years and had no operational launcher of its own. The Shuttle was running years late and several billion dollars over budget. The bill for the Apollo era had come due.

On 12 April 1981 — exactly twenty years after Gagarin — Columbia lifted off from Pad 39A on the first orbital flight of the Space Shuttle. The vehicle had been in development for nearly a decade, was still nominally a prototype, and carried a crew of two on a mission whose fundamental purpose was to find out whether the spacecraft worked.

It mostly did. Over the following 30 years, the Shuttle fleet flew 135 missions, deployed Hubble, repaired Hubble five times, launched the Galileo and Magellan and Ulysses planetary probes, and — most importantly — assembled the International Space Station piece by enormous piece. Whether any of this was good value for money is a question the engineering community will still argue about a hundred years from now. The Shuttle never came close to its cost-per-flight projections. It killed two crews. But for thirty years it was the only spacecraft on Earth capable of hauling a school-bus-sized payload to orbit and bringing one back.

The 1980s also saw a quieter revolution: commercial communications satellites became big enough business to justify a private launch industry, the first space-based interferometers and infrared telescopes opened entirely new astronomical windows, and the Soviet Union flew Mir, the first modular long-duration station. By the time Atlantis landed on 21 July 2011 to end the Shuttle program, two American astronauts had spent more than a year continuously aboard the ISS. The torch was already being passed.

On 4 June 2010, a thin black-and-white rocket lifted off from Cape Canaveral. Falcon 9 reached orbit on its first attempt — a feat the Saturn family, the Shuttle, the Atlas V and the Delta IV had all failed to achieve on their respective debut flights. Two years later, in May 2012, the Dragon capsule launched on Falcon 9 became the first privately built spacecraft to dock with the International Space Station.

What followed was the most consequential structural change in spaceflight since Apollo. SpaceX spent the first half of the decade learning to land the first stage of its rocket — first on a barge, eventually on the launch pad — and demonstrating that a Falcon 9 booster could fly, return, refurbish and fly again. The cost-per-kilogram to orbit, which had been roughly stagnant for fifty years, started falling sharply. Other operators were forced to respond: ULA, Arianespace, JAXA, Roscosmos, ISRO, the new Chinese commercial-launch sector all started reusable-vehicle programs of their own.

The wider commercial-space economy followed. Planet flew the first commercial Earth-observation constellation. Iridium and OneWeb began LEO communications constellations. By 2019, SpaceX had launched the first sixty satellites of what would become Starlink — the largest satellite constellation in history. Investors who had spent forty years dismissing space as a money-losing government enterprise started writing serious cheques. The "NewSpace" label, originally the name of a small annual conference, became the umbrella term for an industry that, by the end of the decade, was tracking close to a hundred billion dollars in annual revenue.

The Apollo program was a contest between two countries. The Shuttle era was a partnership between two countries (the U.S. and Russia, eventually) plus a handful of European customers. The Constellation and Artemis programs of the 2010s and 2020s have been a partnership of dozens — but they are no longer the only game in town.

In February 2021 the United Arab Emirates entered Mars orbit on its first interplanetary mission, becoming the fifth space program ever to do so. Two days later China followed with Tianwen-1, deploying the Zhurong rover to the surface in May. India landed Chandrayaan-3 near the lunar south pole in 2023, becoming the fourth nation to soft-land on the Moon and the first to do so south of 70°. The European Space Agency operates JUICE on its way to Jupiter, Hera on its way to a binary asteroid, and the joint NASA–ESA Hubble and Webb telescopes that have between them rewritten cosmology.

The same period restructured the private sector. SpaceX has launched more mass to orbit than every other nation combined for several years running. Rocket Lab matured into a full space-systems company. Blue Origin finally flew New Glenn. The IPO pipeline — Rocket Lab, Astra, Planet, AST SpaceMobile, Astroscale, Sidus, Spire, Redwire — created a public-market space sector for the first time since the COMSAT era. By 2025 the global space economy was on track to pass half a trillion dollars in annual revenue, with launch finally cheap enough that proposals to do industrial-scale work in orbit no longer felt absurd.

Spaceflight in 2026 looks profoundly different from anything in its history. There are now well over 10,000 active satellites in orbit. Launch cadence has crossed two flights per week for SpaceX alone. The U.S. Space Force is the youngest branch of the American military and is operating its own dedicated launch and constellation programs. China has a permanently crewed space station and has announced firm timelines for its own crewed lunar landing before 2030.

The Artemis II crewed flight took place in April 2026, the first humans to leave low Earth orbit since 1972. SpaceX confidentially filed its S-1 with the SEC on 1 April 2026, in what — if it lists at the rumoured $1.75 trillion valuation — will be by some distance the largest IPO in history. The James Webb Space Telescope is mid-way through its primary mission. Europa Clipper, JUICE, Hera, Psyche, ESCAPADE and OSIRIS-APEX are all in flight to their respective targets. Ten new commercial space stations are in some stage of design, manufacturing or test.
