Here are a few stunning views of the Curiosity Rover’s current location, Mont Mercou in Gale Crater on Mars. This towering outcrop provides a great look at layered sedimentary rock structures. On Earth, it’s common to find layered rock like the ones within this cliff face, especially where there were once lakes. The pancake-like layers of sediment are compressed and cemented to form a rock record of the planet’s history.Continue reading “Mont Mercou on Mars”
What do coal, crude oil, and truffles have in common? Go ahead. We’ll wait.
The answer is thiophenes, a molecule that behaves a lot like benzene. Crude oil, coal, and truffles all contain thiophenes. So do a few other substances. MSL Curiosity found thiophenes on Mars, and though that doesn’t conclusively prove that Mars once hosted life, its discovery is an important milestone for the rover. Especially since truffles are alive, and oil and coal used to be, sort of.Continue reading “Curiosity Finds Organic Molecules That Could Have Been Produced by Life on Mars”
The Curiosity rover on Mars has captured the most detailed panoramic image ever taken of the Red Planet’s surface. The image is made from over 1,000 images, containing 1.8 billion pixels of the Martian landscape, with 2.43 GB of high-resolution planetary goodness.
“This is the first time during the mission we’ve dedicated our operations to a stereo 360-degree panorama,” said Curiosity Project Scientist Ashwin Vasavada.Continue reading “Curiosity’s Latest Mars Panorama, Captured in 1.8 Billion Glorious Pixels”

NASA’s Curiosity Mars rover experienced a technical glitch last week, causing it to temporarily lose its sense of direction and freeze in its tracks. But the talented rover repair team back on Earth enabled a fix, and Curiosity is now back in action.Continue reading “A Glitch Caused Curiosity to Freeze in Place. But It’s Better Now”
An atmospheric drama has been playing out on Mars lately. Up until now, the main actor has been methane, and its unusual, spiking behaviour. But now Oxygen is taking the stage, and performing some theatrics of its own.Continue reading “Molecular Oxygen on Mars is Behaving Unusually Through the Seasons. A Sign of Life?”
If the Curiosity rover was paranoid, would it feel like it was being watched? Well, it is being watched, by its brother in orbit, the Mars Reconnaissance Orbiter. The MRO watched Curiosity as it travelled through the ‘Clay-Bearing Unit‘ in Gale Crater, during June and July, 2019.Continue reading “There’s the Curiosity Rover, On the Move, Seen from Space”
What happened to Mars? If Mars and Earth were once similar, as scientists think, what happened to all the water? Did there used to be enough to support life?
Thanks to the Mars Science Laboratory (MSL) Curiosity, we’re getting a better picture of ancient Mars and what it went through billions of years ago. A new study published in Nature Geoscience says that Mars likely underwent alternating periods of wet and dry, before becoming the frigid, dry desert it is now. Or at least, Gale Crater did.Continue reading “Curiosity Finds A Region of Ancient Dried Mud. It Could Have Been an Oasis Billions of Year Ago”
It’s all about the detail.
In a way, Mars looks like a dusty, dead, dry, boring planet. But science says otherwise. Science says that Mars used to be wet and warm, with an atmosphere. And science says that it was wet and warm for billions of years, easily long enough for life to appear and develop.
But we still don’t know for sure if any life did happen there.Continue reading “Pictures from Curiosity Show the Bottom of an Ancient Lake on Mars, the Perfect Place to Search for Evidence of Past Life”
Since it landed on Mars in 2012, one of the main scientific objectives of the Curiosity rover has been finding evidence of past (or even present) life on the Red Planet. In 2014, the rover may have accomplished this very thing when it detected a tenfold increase in atmospheric methane in its vicinity and found traces of complex organic molecules in drill samples while poking around in the Gale Crater.
About a year ago, Curiosity struck pay dirt again when it found organic molecules in three-billion-year-old sedimentary rocks located near the surface of lower Mount Sharp. But last week, the Curiosity rover made an even more profound discovery when it detected the largest amount of methane ever measured on the surface of Mars – about 21 parts per billion units by volume (
Clay is a big deal on Mars because it often forms in contact with water. Find clay, and you’ve usually found evidence of water. And the nature, history, and current water budget on Mars are all important to understanding that planet, and if it ever supported life.Continue reading “Curiosity has Found the Mother Lode of Clay on the Surface of Mars”
