US defence giant Northrop Grumman has tested an underwater drone that looks like a monster manta ray. The drone is capable of carrying multiple payloads of various sizes, and the machine is autonomous and war-ready.

Northrop Grumman and Umbra have been awarded small contracts by the Defense Advanced Research Projects Agency (DARPA) to continue to the second phase of a program designed to collect data from radar-equipped satellites flying in formation and develop innovative algorithms to process the data for military applications.

Umbra’s contract under the Distributed Radar Image Foundation Technology (DRIFT) program is for $6 million and will last for six months and Northrop Grumman’s is for $2 million and covers one year, a DARPA spokesperson said.

The demonstration is a key milestone in the Air Force Research Laboratory’s Defense Experimentation Using Commercial Space Internet, or DEUCSI — a program launched in 2018 to explore augmenting military communications by leveraging the growing commercial satellite internet industry.

DARPA just tested an autonomous tank that could help keep soldiers safe — and even more self-driving military vehicles are on the horizon. If autonomous vehicles prove capable enough for the battlefield, the tech could someday start finding its way over to civilian uses, too.

The challenge: Tanks have played an important role in the US military for more than 100 years, thanks to their tremendous firepower and armor, but every time the Army puts a soldier into a tank and sends them into combat, it’s putting their life at risk.

Even if the tank is never attacked by an enemy, there’s some evidence that simply firing a tank can cause brain damage for the operators inside, potentially leading to problems with cognition and mental health.

A solar geoengineering experiment in San Francisco could lead to brighter clouds that reflect sunlight. The risks are numerous.

CLIMATEWIRE | The nation’s first outdoor test to limit global warming by increasing cloud cover launched Tuesday from the deck of a decommissioned aircraft carrier in the San Francisco Bay.

Yesterday, Boston Dynamics announced it was retiring its hydraulic Atlas robot. Atlas has long been the standard bearer of advanced humanoid robots. Over the years, the company was known as much for its research robots as it was for slick viral videos of them working out in military fatigues, forming dance mobs, and doing parkour. Fittingly, the company put together a send-off video of Atlas’s greatest hits and blunders.

But there were clues this wasn’t really the end, not least of which was the specific inclusion of the word “hydraulic” and the last line of the video, “‘Til we meet again, Atlas.” It wasn’t a long hiatus. Today, the company released hydraulic Atlas’s successor—electric Atlas.
