FASTER? PLEASE! Breakthrough rocket engine could accelerate to 99% the speed of light.

Burns’ concept, called the “helical engine,” is not a single closed loop. Instead, it’s a helical structure that resembles a stretched-out spring. Burns described the engine as accelerating ions confined in a loop to moderate relativistic speeds, and then varying their velocity to make slight changes to their mass.

The engine moves ions back and forth along the direction of travel to generate thrust. Notably, the engine has no moving parts, except for ions that travel in a vacuum line and are trapped inside electric and magnetic fields.

This concept sounds impressive in theory, but it has some significant practical challenges to overcome. According to New Scientist, the helical chamber would have to be quite large, precisely around 200 meters (656 feet) long and 12 meters (40 feet) in diameter.

Generating 1 newton of thrust would require producing 165 megawatts of energy, which is equivalent to the power output of a power station required to accelerate a mass of 1 kilogram per second squared. Therefore, despite the enormous input, the output is incredibly small, making it a terribly inefficient process.

But in the vacuum of space? It just might work. “The engine itself would be able to get to 99 per cent the speed of light if you had enough time and power,” Burns told New Scientist.

How much time and how much power aren’t exactly trivial questions.

If just for once the people in charge of Biden and all the rest of the Democrat Legion of Destruction would come out and say, ‘We hate you, we hate America, and we want to destroy you, your family, and everything you love. Then we’ll rebuild what’s left using our socialist playset so we can enjoy looking down at you from our after-party in Aspen while your children fetch us another drink.'”

THAT’S GENERAL BERGER, NOT SOCK DOC THIEF SANDY BERGER: Berger Goes Salamander:

Again because it can never be said enough; our military will not be able to meet the challenge of this century until:

We replace Goldwater-Nichols.
We redefine the definition and emphasis of “joint” as it is now practiced, especially in the acquisitions arena.
The COCOM is re-baselined.
On the last part at least, Berger is with me.

HERE’S HOW THAT SPACE PROGRAM IS COMING ALONG: ‘Swarm of boulders’ in space shows the gory aftermath of NASA’s asteroid-smashing DART mission.

On Sept. 26, NASA’s Double Asteroid Redirection Test (DART) spacecraft disintegrated as it smashed into the asteroid Dimorphos, which is 7 million miles (11 million kilometers) from Earth, successfully changing the asteroid’s trajectory.

Now, by using Hubble to study the impact, astronomers have found that DART’s roughly 14,540 mph (23,400 km/h) impact on the asteroid produced a “swarm of boulders.” The rocks, which range from 3 to 22 feet (0.9 to 6.7 meters) in diameter, were most likely shaken loose from the asteroid’s surface during the impact. The researchers published their findings July 20 in The Astrophysical Journal Letters.

“This tells us for the first time what happens when you hit an asteroid and see material coming out up to the largest sizes,” David Jewitt, a planetary scientist at the University of California, Los Angeles, said in a statement. “The boulders are some of the faintest things ever imaged inside our solar system.”

One small step for planetary defense, one giant leap for Hubble imaging.

THE LEFT LOOKS AFTER ITS OWN: Leftist prosecutor booted from office gets $210,000 job at UC Berkeley: ‘If Boudin was hired to relate his experience, the only take could be how to destroy a city’s criminal justice system piece by piece,’ critic says. Plus, a reminder: “The new law center director is the son of Kathy Boudin and David Gilbert, who both served time in prison for murder and robbery.” They’re former members of the Weather Underground. Boudin got a cushy setup with Columbia and a private foundation after getting out of prison; Gilbert got out of prison early thanks to Andrew Cuomo.
