Loading contentFrom the first beep of Sputnik to footprints on the Moon and robots at the edge of the Solar System — the history of spaceflight, told as a connected timeline of eras, events, milestones, and records.
Every landmark event of spaceflight, from Sputnik to Artemis, in chronological order.
57 entriesThe great periods of the space age — the Space Race, the golden age of planetary exploration, the Shuttle and ISS eras, and beyond.
7 entriesThe milestone achievements — the first satellite, the first human in space, the first Moon landing, and more.
15 entriesThe standing records of spaceflight — the most distant, fastest, and longest-lived of humanity's craft and crews.
7 entriesThe crewed milestones — first flights, spacewalks, and space stations.
13 entriesThe great robotic firsts — flybys, orbiters, landers, aircraft, and the missions that returned samples.
26 entriesThe opening of the space age, from the launch of Sputnik 1 to the first probes toward the Moon — the moment humanity's machines first left the Earth.
The Cold-War contest between the Soviet Union and the United States that carried the first humans into orbit and on to the Moon, culminating in the Apollo landings and the détente of Apollo–Soyuz.
The decades in which robotic probes first reached every planet — Mariner, Pioneer, Viking, and the two Voyagers that toured the outer Solar System and reached its edge.
Thirty years of the reusable Space Shuttle — building space stations, launching and repairing great observatories, and marked by the losses of Challenger and Columbia.
The era of continuous human presence in orbit aboard the International Space Station — the largest structure ever built in space and a laboratory for living and working off Earth.
The modern era of spaceflight — reusable and commercial rockets carrying cargo and crew to orbit, alongside a new generation of robotic explorers reaching Mars, the comets, Pluto, and interstellar space.
The return to the Moon — NASA's Artemis program and its international and commercial partners working to land the next humans on the lunar surface and build a sustained presence.
Each era, event, milestone, and record is a first-class knowledge-graph entity resolved through the Scientific Data Engine, reusing the missions, mission programs, astronauts, agencies, stations, telescopes, and worlds already in the graph. Curated from NASA, ESA, and national space-agency records. Dates are given only to the precision that is well established; unknown values are left blank. See source quality.
