What was Sputnik 1?
“The space race ended when the race to the Moon did.”
The Moon race ended in 1969, but spaceflight kept accelerating: space stations, reusable shuttles, and eventually the International Space Station — built and crewed by former rivals working together. Scrub the date dial past 1969 and the event record never goes quiet.
“Nobody is in space right now.”
Someone has been off the planet every second since November 2, 2000, when the Expedition 1 crew boarded the International Space Station. The Time Machine's continuous-presence counter has ticked up every single day since — over two decades and counting.
1.Day one of the Space Age — Sputnik 1 launches— at “?date=1957-10-04 (Sputnik)”
Look at the date dial: it's pinned almost as far left as it can go — the Time Machine simply doesn't travel much earlier, because this is where the Space Age begins. Read the arrival line together: before tonight the sky held only natural lights; after tonight a human-made moon circled the Earth, launched from Baikonur by the Soviet Union. Now point at the 'Meanwhile in space' panel: no humans were off the planet on this date. Not one. The entire cast of space history so far is a single beeping metal sphere.
2.Two humans stand on another world— at “?date=1969-07-20 (Apollo 11 Moon landing)”
We've jumped twelve years. The arrival dossier now names a place that isn't on Earth: the Sea of Tranquility, the Moon, touchdown at 20:17 UTC. Scroll to 'Off the planet on this date' and read the names — the Apollo 11 crew, in flight since July 16. Neil Armstrong and Buzz Aldrin walked on the surface while Michael Collins kept orbiting overhead in the command module. In 1957 this panel said nobody was off the planet; twelve years later, humans are standing on another world. Ask the class: is twelve years fast or slow for that?
3.A telescope launches on Christmas morning — while people live in space
Each student travels to their own birthday (?date=YYYY-MM-DD or the date dial) and reads the 'Meanwhile in space' panel. Write down every name under 'Off the planet on this date' — note the panel says 'at least', because the archive lists notable flights, not every person ever launched. If it says crew records for your date aren't in the archive, record what was 'Flying on this date' instead. Born after November 2, 2000? Also write down the continuous-presence counter: humans had already been living in space that many days when you arrived.
Christmas morning, 2021. The on-this-date record shows the James Webb Space Telescope launching on an Ariane 5 rocket from Kourou, French Guiana — the most powerful space telescope ever built, riding to space on a holiday. But the real lesson is in the 'Meanwhile in space' panel: the counter shows more than 7,700 days of continuous human presence — every second since November 2, 2000. And the 'Off the planet' list isn't empty anymore; it's the normal state of the world now. Compare this screen to the 1957 one: that's the whole arc of the Space Age in two panels.
