On 2 August 1971, near the end of Apollo 15’s final moonwalk, David Scott stood before a television camera holding a 1.32-kilogram geological hammer in one hand and a 30-gram falcon feather in the other. He released them together, and in the Moon’s near-vacuum they struck the dust simultaneously—dramatically demonstrating what Galileo had predicted nearly four centuries earlier.
1+ hour, 5+ min ago (503+ words) Apollo 15 turned a geological tool and a falcon feather into a televised demonstration of equal gravitational acceleration in the Moon’s near-vacuum....
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.
3+ day, 11+ 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....
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.
6+ day, 20+ hour 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, 1+ 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....
Scientists found a 3.7-billion-year-old chemical fingerprint in Australia’s oldest rocks that lines up with Apollo samples when traced back through time — strengthening evidence that Earth and the Moon were mixed together in a giant ancient impact
1+ week, 1+ day ago (381+ words) A distant lunar sample and Earth's most ancient rocks are telling the same isotopic story—one that only makes sense if a catastrophic collision once scrambled our planet and its future Moon together....
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, 3+ 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....
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, 5+ 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…...
On Venus, the atmosphere presses down with 92 times Earth’s sea-level pressure—the equivalent of standing about 900 metres beneath the ocean—while the surface remains near 465°C, hot enough to keep lead permanently molten.
2+ week, 2+ day ago (1061+ words) Venus combines ocean-depth pressure with furnace heat, but its supercritical carbon-dioxide atmosphere is stranger than either comparison suggests....
Deimos may owe both its enormous south-polar depression and strangely smooth surface to a single 300-metre asteroid impact — a blow whose debris spread around the entire moon and would mean Mars’s smaller satellite is essentially a porous rubble pile
2+ week, 5+ day ago (1186+ words) A 320-metre oblique impact can reproduce Deimos's giant polar cavity while redistributing debris across the moon, implying an extremely weak and porous interior....
A microwave-oven-sized experiment inside NASA’s Perseverance rover made history in 2021 by extracting oxygen from Mars’s carbon-dioxide atmosphere—the first demonstration of producing a usable resource from the environment of another planet.
3+ week, 4+ hour ago (1493+ words) MOXIE's first hour on Mars yielded only 5.4 grams of oxygen, but it crossed a larger threshold: another planet had become the source of a useful consumable. By Space Daily Editorial Team · Edited by Lachlan Brown Published August 23, 2026 · How we edit…...
