The prototype thruster is enclosed in a condensable metal propellant (CoMeT) vacuum facility at NASA's JPL. NASA/JPL-Caltech NASA engineers recently tested a next-generation electric propulsion system that could one day power a crewed mission to Mars. NASA fired up a prototype of its electromagnetic thruster inside a vacuum chamber, reaching power levels of up to 120 kilowatts—the highest achieved in U.S. tests of an electric propulsion system. That’s over 25 times the power of the electric thrusters aboard the current Psyche mission, which launched in 2023 on a journey to explore a metal-rich asteroid.

In 1963, USS Thresher imploded at test depth killing all 129 aboard—the Navy blamed a "piping failure" and closed the case. But declassified documents from the 2000s revealed the submarine had over 800 documented defects before diving, whistleblower testimony proved inspectors were pressured to approve faulty welds, and acoustic analysis of the final moments shows the crew knew they were dying for nearly 5 minutes as water flooded in. The Navy knew Thresher wasn't safe, sent her down anyway, then spent 60 years hiding that 129 men died from institutional negligence, not accident. 26 Minute VIDEO AT LINK...............

Anthropic just published a study mapping exactly which jobs its own AI is replacing right now. The workers most at risk are not who anyone expected. They are older. They are more educated. They earn 47% more than average. And they are nearly four times more likely to hold a graduate degree than the workers AI is not touching. The argument is straightforward. Anthropic built a new metric called "observed exposure." Not what AI could theoretically do. What it is actually doing right now in professional settings, measured against millions of real Claude conversations from enterprise users. For computer and...

A man taken into custody after gunfire rang out at the White House Correspondents’ Assn. dinner on Saturday was identified by law enforcement sources as 31-year-old Cole Tomas Allen, of Torrance. Allen was first identified by the Associated Press, which cited unnamed law enforcement sources. Another official not authorized to speak publicly about the ongoing investigation told The Times that Allen was the suspect and that authorities were in the process of obtaining warrants to search addresses associated with him in Torrance. U.S. Atty. for the District of Columbia Jeanine Pirro says the suspect is being charged with two counts...

If you’ve been curious how to become an AI Engineer, the first thing to know is the job has evolved rapidly since generative AI went mainstream. A few years ago, AI engineering looked a lot like traditional machine learning — building and training models from scratch. Today, companies are hiring AI Engineers who can integrate powerful pretrained models, deploy LLM‑powered applications, and ship real AI features that solve real business problems. The job description has changed and so have the skills employers expect. To keep up with this shift, we built a brand‑new AI Engineer career path at Codecademy. Our...

The Obama administration has lifted longtime restrictions on Libyans attending flight schools in the United States and training here in nuclear science, according to a final amendment of the ban recently approved by the Office of Management and Budget (OMB).

History has been made by Stratolaunch, a hypersonic flight test research company headquartered in Mojave, California. The fully autonomous Talon-A2, equipped with landing gear, has successfully exceeded speeds of Mach five and completed its second autonomous landing at Vandenburg Space Force Base. This mission documentary follows the first recovered flight of TA-2, the result of five years of effort and dedication marking a pivotal moment in sustainable hypersonic flight test for our country. Congratulations to the Stratolaunch team and partners on this success! Next steps: fly TA-2 again and again, increasing the cadence of hypersonic flight tests for the United...

In 2003, former McDonnell Douglas executive Harry Stonecipher became the CEO of Boeing and described the company as "run like a business rather than a great engineering firm." Stonecipher made the fateful decision to reject proposals to design a clean-sheet airplane to replace the aging Boeing 727, 737, and 757. By 2011, Boeing's aging 737 was losing to rival Airbus's A320neo, but instead of a new aircraft, the decision was made to upgrade the 737 NG to the 737 MAX. This would allow it to stay within the FAA's original type certification and operate with the same flying characteristics. It...

Four Danish engineering students have captured global attention with their groundbreaking 3D-printed drone that can fly through the air and swim underwater, switching between both with ease. The drone has the potential to reshape search-and-rescue missions, as well as ocean research. The innovative machine was built by applied industrial electronics students Andrei Copaci, Pawel Kowalczyk, Krzysztof Sierocki and Mikolaj Dzwigalo at Aalborg University. It became an internet hit through viral videos showing the drone taking off from beside a pool, diving underwater, swimming around and then flying back up into the air without any help from humans. The secret is...

House Republicans are calling on the Office of the Director of National Intelligence (ODNI) to expedite a national security review of Chinese drone manufacturers like Shenzhen Da-Jiang Innovations Sciences and Technologies Company Limited (DJI Technologies) pursuant to the 2025 National Defense Authorization Act. In a letter to ODNI signed by representatives Elise Stefanik, R-N.Y.; Rick Crawford, R-Ark.; and John Moolenaar, R-Mich., the lawmakers requested timely execution of the review as drone technology quickly accelerates. President Donald Trump signed an executive order last month prioritizing the accelerated integration of Unmanned Aircraft Systems (UAS) into U.S. national airspace. But before that fully...

The dam, which will be located in the lower reaches of the Yarlung Tsangpo river, could generate three times more energy than the Three Gorges Dam, currently the world's largest hydropower plant. ... The Three Gorges hydropower dam required the resettlement of 1.4 million people. Reports indicate that the colossal development would require at least four 20km-long tunnels to be drilled through the Namcha Barwa mountain, diverting the flow of the Yarlung Tsangpo, Tibet's longest river. ... Shortly after China announced its plans for the Yarlung Tsangpo dam project in 2020, a senior Indian government official told Reuters that India's...

Approximately 14,000 years ago, the unprecedented solar event—now judged to be the most powerful known to have occurred—marked Earth’s transition into the Holocene epoch, according to the findings of an international team of scientists. The team traces the event to around 12,350 BC using a new climate-chemistry model specifically designed to reconstruct ancient solar particle activity. This expands the known timeline for ancient solar storms and raises the bar on the upper boundaries of their intensity. Although the event in question was already known from past observations of radiocarbon spikes in ancient wood samples, its scale and magnitude remained unknown....

If your goal is to make money right after college, majoring in engineering is one of the safest bets.

Unless young students learn the predicate mathematics for calculus, our nation will grind to a halt. While Democrats focus on the liberal arts, which train students to be leftist activists beginning in grade school, it is the STEM studies that keep America functioning. As students ascend that ladder of mathematical logic, calculus becomes central to their ability to maintain our systems and invent new ones. Sadly, though, our schools are failing students, not just in teaching calculus but in teaching everything preceding calculus. It is widely recognized among today’s undergraduates that the STEM field is at once among the most...

Voyager 1 is once again returning data from two of four science instruments onboard. Things are looking better for one of NASA’s longest running deep space missions. After a several-month period of problems, engineers have announced that the Voyager 1 spacecraft is not only back online but also transmitting useful data from two of four science instruments. Work is now underway to bring the remaining two instruments up to operational status. Problems began last November, when Voyager 1 suddenly began sending a repeating gibberish signal instead of the science and engineering data it typically sends. Troubleshooting on the 46-year-old spacecraft...

John Barnett had one of those bosses who seemed to spend most of his waking hours scheming to inflict humiliation upon him. He mocked him in weekly meetings whenever he dared contribute a thought, assigned a fellow manager to spy on him and spread rumors that he did not play nicely with others, and disciplined him for things like “using email to communicate” and pushing for flaws he found on planes to be fixed. “John is very knowledgeable almost to a fault, as it gets in the way at times when issues arise,” the boss wrote in one of his...

Crucial science topics will no longer be taught to a large swath of Indian students, according to new government guidance. Most young learners in India will no longer be exposed to key science topics in school textbooks — unless they voluntarily major in science in higher classes. On June 1, India cut a slew of foundational topics from tenth grade textbooks, including the periodic table of elements, Darwin's theory of evolution, the Pythagorean theorem, sources of energy, sustainable management of natural resources and contribution of agriculture to the national economy, among others. A small section explaining Michael Faraday’s contributions to...
