Apollo's 1202 Alarm

Minutes before landing on the Moon, the computer started flashing errors

Minutes from the Moon, the landing computer starts flashing a code no one aboard knows by heart. Do you land, or turn back?

You'll find out

  • What the computer was telling the crew
  • The radar that was stealing its time
  • Why the landing could keep going

Why it matters

Phones and cars run on the same idea today: when there's too much to do, drop what can wait and protect what can't.
