Ikea is known for designing furniture that people can put together themselves. Recently, a team from the Swedish company spent time inside a Mars research center to get new design ideas. For three days, five Ikea designers lived inside the Mars Desert Research Station in the U.S. state of Utah. The center is operated by the Mars Society. It simulates a Mars environment for humans taking part in experiments and training. Real astronauts have spent long periods of time inside the research center to prepare for space flights.
