7 de may. de 2024 · Past Mars Investigations. Like the Earth, the climate of Mars has changed over time. Today, Mars is cold and dry and liquid water is not stable on the surface. However, very early in the planet’s history (more than 3.5 billion years ago), climatic conditions appear to have been favorable for the presence of liquid water on the surface.
