Last month, NASA's Mars InSight lander started digging into the Red Planet. Its HP3 (Heat Flow and Physical Properties Package) instrument was designed to burrow and measure Mars from underground, uncovering new geological evidence about how heat flows through the Martian soil. The part of this instrument that actually burrows into the ground is known as the mole. It was meant to penetrate up to 16 feet deep. But it stopped just hours after it starting digging.

Over the last half century, spacecraft have visited every planet and their major moons, as well as two dwarf planets and more than a dozen asteroids and comets. Thanks to high-res images, we know these worlds intimately and can appreciate what makes each of them unique. These days, fewer than 3 in 10 Americans are old enough to recall a time when our neighboring worlds were indistinct dots in even the most powerful telescopes.
And yet, even before there were spacecraft to show us, in the ...read more
Age 116, Kane Tanaka of Japan was recently crowned the oldest person on Earth. She’s six years shy of the longest human life on record: 122 years and 164 days reached by a French woman, Jeanne Louise Calment, before her death in 1997.
While turning 100 can get you a shout out on the Today show, there’s nothing newsworthy about surviving into your 70s. That’s just expected based on life expectancy. In the United States, on average, newborn males live to 76 years and female ...read more
Have you ever wished for eyes in the back of your head? How about your rear end?
Researchers at the University of Adelaide in Australia have been studying “seeing” tails among several species of Australian sea snakes. That includes the olive sea snake, Aipysurus laevis, pictured here.
Their long tails make a tempting target for predators, but evolution has endowed at least three species of these sea snakes with a neat trick: the skin on their tails can sense light.
The scientists ...read more
After more than 60 years, McMurdo Station, Antarctica’s main research center, is set to begin its first major infrastructure update. In February, the National Science Foundation got the green light to start construction on the so-called Antarctica Infrastructure Modernization for Science, or AIMS, project.
As first reported by Antarctic Sun, the continent's NSF-funded newspaper, the project will consolidate the sprawling research station’s some 100 buildings into just six prima ...read more
