WASHINGTON — NASA’s first look at a tiny asteroid shows the space rock is more moist and studded with boulders than originally thought.
MOSCOW — Two Russian cosmonauts were preparing to venture outside the International Space Station Tuesday to inspect a section where a mysterious leak has been discovered.
WASHINGTON — Scientists think they’ve figured out the falling dominoes that led to Earth’s largest mass extinction and worry that human-caused climate change puts the planet on a vaguely similar path.
CAPE CANAVERAL, Fla. — After a two-year chase, a NASA spacecraft arrived Monday at the ancient asteroid Bennu, its first visitor in billions of years.
CAPE CANAVERAL, Fla. — Minutes after touching down on Mars, NASA’s InSight spacecraft sent back a “nice and dirty” snapshot of its new digs. Yet the dust-speckled image looked like a work of art to scientists.
The photo revealed a mostly smooth and sandy terrain around the spacecraft with only one sizable rock visible.
CAPE CANAVERAL, Fla. — A NASA spacecraft’s six-month journey to Mars neared its dramatic grand finale Monday in what scientists and engineers hoped would be a soft precision landing on flat red plains.
The InSight lander aimed for an afternoon touchdown, as anxiety built among those involved in the $1 billion international effort.
WASHINGTON — Cat lovers know when kitties groom, their tongues are pretty scratchy. Using high-tech scans and some other tricks, scientists are learning how those sandpapery tongues help cats get clean and stay cool.
The secret: Tiny hooks that spring up on the tongue with scoops built in to carry saliva deep into all that fur.
ANCHORAGE, Alaska — The first formal count of polar bears in waters between the United States and Russia indicates they’re doing better than some of their cousins elsewhere.
OAKFIELD, N.Y. — Cows that can withstand hotter temperatures. Cows born without pesky horns. Pigs that never reach puberty.
A company wants to alter farm animals by adding and subtracting genetic traits in a lab. It sounds like science fiction, but Recombinetics sees opportunity for its technology in the livestock industry.
