How the puzzle works

• One space question a day, the same for everyone in the world. A new puzzle opens at 00:00 UTC. A puzzle you opened before midnight UTC still counts for its own day if you finish it after.
• Two tries. Your result is 1/2 (first try), 2/2 (second try) or X/2 (missed), and the share grid shows only that, never the answer.
• Every question was checked by hand against an official source (NASA, ESA, JAXA, NOAA, the UN and the like) on the date shown with the answer. Spotted a mistake? Tell us and we will correct it in public.
• Your streak counts the days you play (or finish a Learning Zone lesson, or watch 30 seconds of the latest SpaceNexus Daily). Every 7 days in a row earns a freeze that covers one missed day, up to 2. Freezes are earned, never sold.
• Your answers stay in this browser. We count starts, finishes and shares as daily totals, with no cookie and nothing that identifies you.
• Nothing in the puzzle is sponsored or paid for.
