This informational poster from AVIC shows the launch sequence of the artillery UAV. It's deployed from a 155mm shell (PLZ-04 howitzer) or 300mm rocket (A-100 rocket launcher), and when nearing deployment, the shell deploys a drag parachute to slow down. At the slower speed, the shell splits open so the drone can safely deploy. Despite the drone's small size, its sensors are capable enough of detecting specific targets like the M1A2 Abrams tank.

There's nothing quite like that first bite of a fresh fruit. The range of aromas and flavors offer a momentary respite from everyday life and provide to body with a plethora of nutrients to improve overall health. But there is a dark side manifested in the presence of a number of speck-sized flying frustrations better known as fruit flies.

So there are a couple of—let's say, health outcomes—that are popularly associated with unusual snowfall. One is heart attacks: It's commonly believed that shoveling snow can over-strain the heart. The other is pregnancy: Couples stuck indoors, it's thought, may find themselves in a certain mood.

The science of blizzards and how to overcome them have been a part of Popular Science since at least the magazine's second decade. In an 1883 treatise on poorga”, the Russian term for the same phenomenon, of a “blinding snowstorm against which nor man nor beast may stand,” never caught on the way blizzard did.

As folks in the U.S. East Coast prepared for a major blizzard yesterday, the sky offered a little gift: Large snowflakes that look like macroscopic versions of what snow normally looks like under a microscope.

Deep within the bowels of our Milky Way Galaxy, there is another solar system that is like a miniature replica of our own. Except this planetary system is just a tad older — by about 7 billion years.

On January 27, 1967, spacecraft 012 was mated to its service module and Saturn IB rocket, and the whole stack was on the launch pad. At one o'clock in the afternoon, the spacecraft's crew, Gus Grissom, Ed White, and Roger Chaffee climbed inside the spacecraft for the plugs out test, a routine test NASA ran before all its missions that ran a simulated countdown with the spacecraft running on its own internal power. The hatch was closed, the cabin was pressurized, and the crew and launch teams and flight controllers took their stations at the Cape and in Mission Control in Houston.

NASA's Dawn mission has beamed back the best-ever view of a 'planet' between Mars and Jupiter. The spacecraft is just 147,000 miles and a few months shy of reaching Ceres, the largest unexplored rock between the Sun and Pluto. (Though the 590-mile-wide rock is officially classified as both a dwarf planet and the largest asteroid in the asteroid belt, Dawn's operators consider it a real planet.)

Today, the American Academy of Pediatrics is publishing a report on recreational marijuana use among kids under the age of 18. Like a good pediatrician, the report summarizes the latest research to answer kids' and parents' most pressing questions. Is pot bad for young brains? Will the newest wave of changes in American law about marijuana make things better or worse? The report ends with a recommendation for lawmakers and voters: Laws need to change so that young people aren't punished severely for recreational marijuana use.

While NASA's Dawn mission is hot on the tail of the biggest rock in the asteroid belt, researchers are still finding new things within the treasure trove of data the spacecraft collected in 2011 and 2012. Back then Dawn was visiting Vesta, the second-largest object in the asteroid belt, which scientists thought would be bone-dry.

In his State of the Union Address last week, President Obama mentioned drones exactly once. Out of respect for human dignity, he said, our use of drones should be “properly constrained.” When he said “constrained,” Obama was referring to military drones, not toy drones, but now, he might have a personal interest in constraining smaller ones. Early this morning, while the president was away visiting India, the Secret Service found a crashed drone on the south lawn of the White House.

29 million people in the northeastern United States are currently under a blizzard warning. That means 29 million people are being warned off the roads, desperately crowding grocery stores to buy bread and milk, and preparing for the inevitable arguments that will arise when the entire family is trapped together in the house for days at a time.
