JPL-Caltech/NASAWater is ubiquitous on Earth – about 70% of Earth’s surface is covered by the stuff. Water is in the air, on the surface and inside rocks. Geologic evidence suggests water has been stable on Earth since about 4.3 billion years ago. The history of water on early Mars is less certain. Determining when water first appeared, where and for how long, are all burning questions that drive Mars exploration. If Mars was once habitable, som…

Earth and Mars were very similar in their youth. Four billion years ago, both planets had vast, warm seas. But while Earth retained its oceans, the waters of Mars evaporated away or froze beneath its dusty surface. Exactly why these two worlds took such divergent paths is unclear, though it may lie in the origins of their water.  Based on geological studies, we know that Earth’s water cycle seemed to have stabilized early. From about 4.5 billion…

There was Hot Water on Mars 4.45 Billion Years Ago

Welcome back to the Abstract! As snow begins to fall and chilly weather becomes the norm, let’s mentally sink into the hot baths that existed on the surface of ancient Mars. Scientists presented unprecedented evidence of these Martian hydrothermal systems inside an ancient crystal found in the Sahara. Of course, all ancient crystals from the Sahara are special, but it turns out this extraterrestrial one is particularly full of wisdom.  Then, ind…

An Ancient Crystal from the Sahara Reveals a Lost World of Martian Water

A Martian meteorite nicknamed Black Beauty Carl B. Agee (University of New Mexico)    Crystals inside a Martian meteorite hint that there may have been plentiful hot water on Mars when the rock formed 4.45 billion years ago. The rock, nicknamed Black Beauty, was blasted into space by an impact on the surface of Mars before ultimately crashing into the Sahara desert. Much has already been learned about Mars from studying the meteorite, which was …

4.45 billion-year-old time capsule from Mars: Evidence of a watery world.Water has always been a defining feature of Earth, covering 70% of its surface and influencing every aspect of our planet's life and geology for billions of years. But did you know water might have played a significant role on Mars almost as far back as its formation? A groundbreaking study now suggests that Mars may have been wet as early as 4.45 billion years ago, paintin…
