July 16 marks the 50th anniversary of the Apollo 11 launch, when Neil Armstrong and Buzz Aldrin set out to become the first humans to land on the moon.

In the years since that crowning moment, the US space program has witnessed countless other achievements: the landing of a spacecraft on Mars, the launch of the Hubble telescope, and the permanent occupancy of the International Space Station.

It also also managed to improve the culinary experience for astronauts. While today's astronauts still eat packaged meals, their food has a lot more variety and flavor than what Armstrong and Aldrin ate in 1969.

Take a look at the evolution of astronaut food from the 1960s to now.
