I'd never seen this NASA photo of Apollo 17 astronaut Gene Cernan before. It was taken after one of his three moonwalks with crewmate Harrison Schmitt, though you could be forgiven for assuming that Cernan just came in from a shift at the coal mine rather than a jaunt across the surface of the Moon.
At the Life, Unbounded blog, Caleb Scharf writes about the Moon dust you can see clinging to Cernan, describing it as sticky, abrasive, and gunpowder-scented. It's also not something we totally understand yet — at least, we still have a lot to learn about how Moon dust behaves on the Moon. On September 6, NASA is launching a satellite to study this very phenomenon. One thing it might figure out: Whether electrically charged particles of Moon dust might form an extremely thin and vanishingly temporary "atmosphere" that hovers and falls over the Moon's surface.
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
This is so amazing. Watch what happens when a blacksmithing anvil is lowered into a large vat of pure liquid mercury. Update: One of our readers posted the link to the original video in the comments. I have replaced the animated GIF. Thanks, Crispy75. [H/t Alberto Gaitán via Bryce Lynch] Image: Screengrab from GIF
Two-thirds of American adults drink coffee every day. On average, they’re each drinking about three cups per day, which works out to nearly 400 million cups downed each and every day. We don’t have stats on what percentage of those cups are God awfully bad, but you have to assume with so many ways to […]
For those with a writing flair, the thought of building a career as a professional copywriter should probably have some appeal. Thankfully, it’s also an in-demand job skill with the average copywriter making a healthy $60,000 a year for their efforts. But even if you have a way with words, you still need the industry […]
While we all love our iPhones and iPads, celebrating the releases of their latest and greatest versions, it’s amusing to consider how much we at the same time HATE the main item that keeps these little tech marvels powered up and working. No, Lightning cables don’t exactly inspire feelings of awe and wonder. It’s more […]
