A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace’s aircraft does go supersonic on a later date, it will be powered by a Rotating Detonation Rocket Engine (RDRE).

Supersonic drones may sound like something bleeding edge, but they’re surprisingly old hat as a basic concept. As far back as the early 1950s, the US Air Force was fielding remote-controlled supersonic jets for targets to test air defenses, as platforms for reconnaissance in dangerous areas, or as weapons armed with conventional or nuclear warheads.

A Japanese rocket by startup Space One has exploded in spectacular fashion following a launch attempt earlier today.

It’s yet another major setback for the company, which was hoping to become Japan’s first commercial entity to launch a satellite into orbit, the New York Times reports.

Drone footage shows the dramatic scene. At first, everything appears to go fine as the solid-fuel rocket dubbed Kairos lights its engines. But it doesn’t take long for the rocket to seemingly veer off path, erupting into a massive cloud of smoke just seconds later, causing major pieces of debris to rain down on the launch pad and engulf parts of the facility and a neighboring forest in flames.

Mr. Xia further noted the expanding utility of unmanned technologies across various domains, including aerial, maritime, underwater, and terrestrial operations, underscoring their revolutionary impact on future military engagements.

“A drone costing just a few thousand dollars can effectively neutralize an advanced tank worth over 5 million dollars,” Mr. Xia said, illustrating a remarkable disparity in warfare economics.

Drones’ ease of manufacture, low detection and radar interception rates, and precision targeting via satellite data further accentuate their tactical viability. Importantly, drones facilitate offensive operations without compromising soldier safety, marking a significant evolution in how military objectives are pursued.

EVTOL battery analysis reveals unique operating demands. Researchers at the Department of Energy’s Oak Ridge National Laboratory are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically.

These aircraft, commonly called eVTOLs, range from delivery drones to urban air taxis. They are designed to rise into the air like a helicopter and fly using wing-borne lift like an airplane. Compared with helicopters, eVTOLs generally use more rotors spinning at a lower speed, making them both safer and quieter.

The airborne EV’s aren’t just flying cars, and ORNL researchers conclude that eVTOL batteries can’t just be adapted from electric car batteries. So far that has been the dominant approach to the technology, which is mostly in the modeling stage. ORNL researchers took a different tack by evaluating how lithium-ion batteries fare under extremely high power draw.

DoorDash and Wing (an Alphabet company) have announced their first joint drone delivery service in the United States. Targeted at select customers in Christiansburg, Virginia, eligible DoorDash orders from Wendy’s can now be delivered via Wing drone.

Wendy’s orders will be delivered using a Wing drone, which can travel up to 65 mph. Upon reaching its destination, the drone will lower the order to the doorstep using a tether.

Tesla continues to make progress on its upcoming diner, drive-in theater and Supercharger in Los Angeles, with recent drone footage showing new water runoff infrastructure, preparations for stucco installation on the first-floor walls, and seemingly, materials for the start of some interior construction.

In a drone video update shared by YouTube channel 247Tesla on Sunday, you can see new stacks of sheetrock both inside and outside of entrances to the Tesla diner building, as construction prepares to begin focus on interiors. The video also shows a new rectangular area dug roughly five feet deep into the ground, which the video’s host says will likely be used to control water runoff.

FCC cracks down on retailers like Amazon allegedly selling illegal signal jammers. Investigations are underway.

Uh-oh, Amazon. Looks like the Federal Communications Commission (FCC) is not playing around when it comes to selling illegal signal jammers. The agency just went public with an investigation into Amazon and other major retailers for allegedly pushing these dodgy devices that can block your cell signal, GPS, and more.

Typically advertised as “drone deterrents” or “privacy tools”, these nefarious gadgets are specifically designed to block radio frequencies. This has serious ramifications, cutting off cellular devices and GPS units and impacting emergency communication channels.

“The challenge is getting into those hidden places,” says Machado. “It’s rare that Aedes aegypti breeding areas are found out in the open, like on a sidewalk, because when people see them, they destroy them. But with drones, we can get into areas we just can’t otherwise.”

Birdview has carried out studies with several partners since 2021, including the United Nations, the University of São Paulo (USP), and the state-owned Brazilian Agricultural Research Corporation (Embrapa), to better understand the effectiveness of releasing the disease-fighting mosquitoes with drones. First they looked at how the mechanism of the drone and outside conditions, like wind turbulence, affected the survival rate of the mosquitoes and their ability to fly.

The results were positive, so they moved on to flight-and-release tests in the Brazilian states of Pernambuco and Paraná, as well as Florida, where they’ve been working with the Lee County Mosquito Control District to see how far the mosquitoes spread upon release. They used the “mark, release and recapture” method, which involves sterile male mosquitoes being marked with a certain color before being released and later recaptured with traps so the team could see how far they had flown. They also set traps where eggs could be laid and monitored.

Researchers claim to have combined the benefits of rolling robots with those of flying drones by creating a device that rotates along the ground but hops over obstacles.
