Two SpaceX Falcon 9 rockets have completed back-to-back Starlink launches less than 24 hours apart, successfully delivering 106 Starlink satellites to low Earth orbit (LEO).

Originally scheduled just a handful of hours apart, slight delays eventually saw Starlink 4–13 and Starlink 4–15 settle on 6:07 pm EDT, May 13th and 4:40 pm EDT, May 14th, respectively. Entering the final stretch, launch preparations went smoothly and both Falcon 9 rockets ultimately lifted off without a hitch.

The series began with Starlink 4–13 on Friday. SpaceX chose Falcon 9 B1063 to support the Starlink launch and the booster did its job well, wrapping up its fifth launch since November 2020 with a rare landing aboard drone ship Of Course I Still Love You (OCISLY). Since SpaceX permanently transferred OCISLY from the East Coast to the West Coast in mid-2021, the drone ship has only supported five booster recoveries. Save for an unusual East Coast Starlink launch in May 2021, Falcon 9 B1061 has also primarily been tasked with supporting SpaceX’s West Coast launch manifest. With only one older pad – Vandenberg Space Force Base’s (VSFB) SLC-4 complex – available to SpaceX, the company’s West Coast Falcon launches are also considerably rarer than its East Coast missions.

Anyone else find it fascinating that we have all this tech and still can’t compete with nature?

A trio of researchers at City University of Hong Kong has developed a tiny drone based on the maple seed pod. In their paper published in the journal Science Robotics, Songnan Bai, Qingning He and Pakpong Chirarattananon, describe how they used the maple seed pod as an inspiration for increasing flight time in under 100-gram drones.

Maple seed pods are well known for their helicopter-type design. As they fall from the tree, they spin like a helicopter with no engine, increasing their distance from the tree as they are blown afar. In this new effort, the researchers sought to take advantage of the efficiency inherent in the structure of the maple seed pod to increase for tiny . To that end, they built a tiny drone that can spin like the maple seed pod to keep aloft. The resulting drone could fly for nearly twice as long as those with a traditional four-rotor design.

Most drones have spinning rotors to provide lift. This new design features two tiny rotors at the tips of the wings to make them spin—the lift comes courtesy of the spinning wings, which accounts for its improvements in efficiency. The researchers also added electronics and a battery at the center of the drone. The whole thing weighs less than 35 grams and spins at approximately 200 rpm. Testing showed it capable of hovering in the air for up to 24 minutes. The researchers note that due to the inherent stability of the design, no stabilizing microprocessor is needed. They also noted that they were able to realize position-controlled flight by manipulating the speed of the tiny rotors.

A technological demonstration from China recently presented the power of super drones that track objects and people with high precision. The remote-powered vehicles, developed by scholars from Zhejiang University, were deployed into a thick bamboo forest to test their capabilities.

A video released by the researchers shows that the drones maneuvered effectively over the complex obstacles of the forest. The demonstration of the machines creeped out many audiences, as the precision and navigation of the drones exceeded far more than those of the technologies we see today.

Engineers from China developed what might be the most advanced drone swarm to date. Learn more about the autonomous machines and how they performed in tests.

A swarm of 10 bright blue drones lifts off in a bamboo forest in China, then swerves its way between cluttered branches, bushes and over uneven ground as it autonomously navigates the best flight path through the woods.

The experiment, led by scientists at Zhejiang University, evokes scenes from —and the authors in fact cite films such as “Star Wars,” “Prometheus” and “Blade Runner 2049” in the opening of their paper published Wednesday in the journal Science Robotics.

“Here, we take a step forward (to) such a future,” wrote the team, led by Xin Zhou.

That’s 25 times faster, at 80 percent the cost of conventional means.

Combating climate change and biodiversity loss is a complicated matter, causing prolonged and perhaps tedious conversations. But what if there was a cooler way to achieve all that?

Enter Australian start-up AirSeed Technology and their swarms of seed-firing drones that are planting 40,000 trees a day to fight deforestation. The company and its incredible technology were featured Wednesday on * Euro Green News*. drone that can plant 40,000 trees a day could be essential in fighting deforestation.

Drones with ion drive. now if could rig it up with indefinite batteries and solar power skin and a tesla wave receiver system.

Undefined Technologies has revealed the new design of its ion drone MIAMI, APRIL 18, 2022 – Undefined Technologies, a Florida-based tech startup, has unveiled the new aesthetic design of its silent eVTOL drone powered by ion propulsion. The concept vehicle named “Silent Ventus™” uses proprietary technology to fully use the ion cloud surrounding the craft to generate high levels of ion thrust in atmospheric air. “Silent Ventus™ is a vivid example of our intent of creating a sustainable, progressive, and less-noisy urban environment,” says Tomas Pribanic, Founder and CEO of Undefined Technologies. “The design brings us closer to our final product and enables us to showcase the dual-use of our technology.”
