Europa isn’t just another icy moon. It’s one of the most fascinating places in our solar system—and possibly one of the best places to search for extraterrestrial life. But let’s imagine something even more personal: what if you could walk on it?
First, Getting There
Europa orbits Jupiter, nearly 628 million kilometers (390 million miles) from Earth. That’s six times farther than Mars. A robotic probe takes about 6 to 8 years to get there with gravity assists.
So you’d need a ship capable of interplanetary travel, life support for a very long journey, and heavy radiation shielding—Jupiter’s magnetic field is so intense, it can fry electronics in days and kill a human in hours without protection.
Stepping Onto Europa
Europa’s surface is made almost entirely of ice. But it’s not the snow-like ice you’d find in Antarctica. It’s hard, brittle, and razor-sharp in places, due to extreme cold and geological activity.
-
Temperature: Around −160°C (−260°F).
-
Gravity: Only 13% of Earth’s—you’d feel practically weightless.
-
Atmosphere: Essentially none. You’d need a pressurized spacesuit with heat regulation and radiation shielding just to survive a few minutes.
Walking here would feel strange: the icy ground might crack under your boots, and the silence would be absolute—until Jupiter itself rises over the horizon, a gas giant 40 times wider than the Moon in Earth’s sky.
What Lies Beneath
The most amazing part? Beneath Europa’s icy crust—perhaps just 10 to 30 kilometers thick—there’s a vast liquid ocean. Scientists believe it may contain more water than all of Earth’s oceans combined. And where there’s liquid water, there’s a chance for life.
That makes Europa more than just a frozen moon. It’s a world of mystery, with volcanic ocean floors possibly teeming with alien microbes.
So… Could You Walk There?
In theory, yes—with a proper landing, the right suit, and a lot of courage. But it wouldn’t be a stroll in the park. It would be more like stepping onto an alien ice sheet, on a world frozen in silence, hiding an ocean full of secrets.
