Designing an airplane that can fly on Mars! First we put a rover on Mars, then a helicopter (Ingenuity). But what about airplanes? This study describes the design of special wings that will help airplanes fly in the thin Martian atmosphere

Can #airplanes fly on #Mars? Maybe! Find out the perfect wing shape for flying in the thin Martian atmosphere.

Early Martian life may have used sulfur as an energy source Using an environment on Earth that simulates early Mars conditions, researchers found an abundance of bacteria that get their energy from sulfur-containing molecules, suggesting a new focus in the search for biosignatures on the Red Planet.

How would we establish a society on Mars? Humans are not built for Mars. Or rather, Mars isn't built for us. Understanding the sacrifices such a massive undertaking needs is important to its success.

We aren’t that far off from Mars colonies. But humans are not built for Mars. Or rather, Mars isn’t built for us, yet. Understanding the sacrifices such a massive undertaking needs is important to its success.
