Garnet had never been confirmed in a Martian meteorite until researchers examining NWA 8171 at the Royal Ontario Museum found andradite inside a fragment smaller than one millimetre. Some surrounding minerals carry Martian chemistry, but scientists cannot yet tell whether it records an unknown magma, ancient fluid alteration, metamorphism—or debris from an asteroid that struck Mars.
13+ hour, 50+ min ago (766+ words) Andradite in the NWA 8171 Martian breccia is secure, but its tiny host clast could record Martian magma, alteration, metamorphism or material delivered by an impactor.

Opportunity’s solar panels were mysteriously getting cleaner long before the rover ever saw the suspected culprit: it did not photograph its first Martian dust devil until six and a half years after landing.
3+ day, 18+ hour ago (1267+ words) Opportunity’s changing power output recorded repeated wind-cleaning events years before its camera caught a dust devil. The six-and-a-half-year gap reveals the difference between detecting an effect and identifying its cause. By Mission Notes · Edited by Lachlan Brown Published September 10, 2026 · How…...
Olympus Mons grew so massive that parts of its lower flanks catastrophically collapsed, sending broken rock sliding hundreds of kilometres across the Martian plains—possibly lubricated when hot lava melted buried ice.
4+ day, 21+ hour ago (718+ words) Orbital evidence links Olympus Mons's aureole to immense flank failures. Water or ice may explain the long runout, but lava-driven melting remains one proposed mechanism....
In 2008, a team hauled 1,478 lunar data tapes and four obsolete drives to NASA Ames to recover pictures from the 1960s — and the laboratory where they restored those original views of the Moon in greater detail was an abandoned McDonald’s restaurant.
5+ day, 14+ hour ago (309+ words) The Lunar Orbiter Image Recovery Project restored old tape drives inside a former McDonald’s to retrieve detail preserved in recordings from the 1960s....
Despite being only about half Earth’s diameter, Mars has nearly as much total surface area as all of Earth’s continents combined—the difference is that oceans cover 71% of our planet, while modern Mars has no permanent bodies of liquid water.
1+ week, 1+ day ago (980+ words) Mars has about 97% as much surface area as Earth’s dry land, a geometrical coincidence created by the oceans covering most of the larger planet....
Nearly every element in your body except hydrogen was forged by stars—the calcium in your bones and much of the iron in your blood came through ancient supernovae, while the hydrogen flowing through you was born before the first star existed.
1+ week, 2+ day ago (982+ words) Hydrogen predates the stars, while generations of stellar fusion, supernovae and galactic recycling supplied the heavier elements now arranged into living bodies....
By the age of eight, a girl in northeastern Brazil was working through sky-survey images on two computer screens and had logged 18 preliminary asteroid detections; if confirmed, they would make her younger than Luigi Sannino, who was 18 when he set the r
1+ week, 2+ day ago (592+ words) A Brazilian girl's methodical scan of deep-space data threatens to upend a record that's stood for a quarter century, raising questions about who gets access to the tools of discovery. By The Daily Orbit · Edited by Mal James Published September…...
Hollywood exaggerates Martian storms in a specific and measurable way: because Mars’s atmosphere is roughly 100 times thinner than Earth’s, a 60-mph gust would push an astronaut about as hard as a gentle 6-to-8-mph breeze on Earth.
1+ week, 5+ day ago (1221+ words) Wind loading depends on air density and speed squared. In Mars's thin surface atmosphere, a 60 mph gust exerts roughly the same push as a 6-to-8 mph Earth breeze, while dust remains a serious hazard to power and machinery....
Venus comes nearer to Earth than any other planet, yet averaged over time the closest planet to Earth is Mercury — and by the same arithmetic Mercury is also the closest planet to Neptune, because a body hugging the Sun can never wander far from anyone
1+ week, 6+ day ago (290+ words) The planet we think is closest to Earth isn't—and neither is any other planet what it seems when you average the numbers correctly....
For most of human history, anyone standing beneath a clear, moonless sky could see the Milky Way. Electric light began erasing that view little more than a century ago—and today, artificial skyglow hides our galaxy from more than one-third of humanity.
1+ week, 6+ day ago (1528+ words) The one-third figure comes from a 2016 global model using 2014 satellite data and 35,000 ground checks. Later naked-eye reports suggest the visible night has continued to brighten. By Deep Field · Edited by Lachlan Brown Published August 31, 2026 · How we edit Wait long enough…...
