Here's a Cool Tip: Dock SpaceX Dragon to the ISS.
Most browser games reward fast clicks. SpaceX’s Dragon docking simulator punishes them.
That is what makes it such a clever Cool Tip.
Instead of racing, blasting, or collecting points, your job is to line up a Crew Dragon spacecraft with the International Space Station using small, careful movements. SpaceX says the simulator uses controls based on the actual interface NASA astronauts use to manually pilot Dragon 2 to the ISS.
The goal is simple to understand but surprisingly hard to master: keep the spacecraft aligned, centered, and moving slowly enough to dock safely.
