Frequent questions

What evidence has been found on Mars that suggests the existence of liquid water in the past or present?

Strong evidence suggests that liquid water existed on Mars in the past and may still exist today. Here are some key findings:

1. Surface Features: The presence of ancient dried-up riverbeds, canyons, and deltas on the Martian surface indicates that water once flowed on the planet. These features resemble those formed by liquid water on Earth.

2. Polar Ice Caps: Mars has polar ice caps composed mostly of water ice. These caps consist of layers that were formed over time, suggesting periods of freezing and melting.

3. Recurring Slope Lineae (RSL): RSL are dark, narrow streaks that appear on certain slopes during warm seasons and fade during colder periods. These features are believed to be caused by the flow of briny water, although the exact mechanism is still under investigation.

4. Seasonal Changes: Observations from orbiters and rovers have shown seasonal changes in the Martian landscape. Dark patches that grow and shrink with the seasons have been interpreted as transient liquid water seeping out onto the surface.

5. Presence of Minerals: Some minerals detected on Mars, such as hydrated salts, are indicative of past or present interactions with liquid water. These minerals have been found in various locations, including recurring slope lineae and ancient lakebeds.
