Week 6: Cosmic Horizons

Visual clue. Each stamp clearly displays a rocket launching vertically into the sky with exhaust flames or smoke trailing below.

The hook. These stamps celebrate the liftoff phase of space missions as launch vehicles blast off from Earth into space.

Visual clue. Each stamp depicts a large inhabited orbital outpost or space station floating above planet Earth.

The hook. These designs depict long-duration orbital habitats including Salyut, Skylab, and Mir where crews live and conduct research in orbit.

Visual clue. Each stamp presents a close-up portrait of a single astronaut or cosmonaut wearing a flight helmet.

The hook. These stamps honor famous early space pioneers from the Mercury and Vostok eras, such as Scott Carpenter, Yuri Gagarin, Gherman Titov, and Virgil Grissom.

Here's the trap we set. Players naturally want to lump all space travelers together. These four specifically present close-up head-and-shoulders portraits wearing helmets, separating them from stamps depicting moonwalks.

Visual clue. Each stamp depicts astronauts standing, walking, or descending onto the lunar surface with lunar landers or craters visible.

The hook. These issues illustrate human exploration on the surface of the Moon, commemorating the historic Apollo lunar landings and early lunar visions.

Here's the trap we set. Resolves the split-species trap. Rather than a generic astronauts category, these four tiles share the specific setting of walking or landing on the Moon.
