A moon lander game with six worlds and a daily mission
Rocket Landing: Moon Lander is an arcade rocket-landing game. Keep a falling rocket over the pad and touch down before the fuel runs out. Fly 59 missions across six worlds: Earth, the Moon, Mars, Titan, Europa and a tower-catch world, each with its own gravity, drag and wind. A new daily mission is the same for every pilot on that date, and online you can race a ghost of another pilot's run. After a crash, read your apology letter to Elon. Free with ads; one optional purchase removes them.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
