While the world’s major powers are locked in an arms race to develop the best and most advanced hypersonic weapons, missiles capable of flying faster than Mach 5 and are thus able to defeat missile defense systems and radars, the Defense Advanced Research Projects Agency (DARPA) has been flying at these speeds for more than a decade.

The history of hypersonics go back much, much further than the 21st century. Nazi Germany’s V-2 rockets were able to reach speeds of Mach 4.3 after takeoff, but when they struck targets, they were often exceeding Mach 5. By 1949, the United States had adopted German rocket technology, which allowed rockets to exceed Mach 5 on takeoff for the first time.

Through this development, the U.S. was able to build its intercontinental ballistic missile arsenal, all of which were capable of speeds above Mach 5 upon reentry. It wasn’t until 1980 that hypersonic research began to focus on glide maneuvering and carrying people. This led to the creation of the X-15 rocket plane, a manned craft that could reach those speeds but was launched from a B-52 “mother ship.” An X-15 holds the official world record for the highest speed ever recorded by a crewed, powered aircraft when it reached Mach 6.7 in 1967.

To check that atomic weapons work, scientists run simulations of explosions using high-energy lasers—and Russia is building the strongest one of all.

But as I describe in my book “Spark: The Life of Electricity and the Electricity of Life,” even before humanmade batteries started generating electric current, electric fishes, such as the saltwater torpedo fish (Torpedo torpedo) of the Mediterranean and especially the various freshwater electric eel species of South America (order Gymnotiformes) were well known to produce electrical outputs of stunning proportions. In fact, electric fishes inspired Volta to conduct the original research that ultimately led to his battery, and today’s battery scientists still look to these electrifying animals for ideas.

Prior to Volta’s battery, the only way for people to generate electricity was to rub various materials together, typically silk on glass, and to capture the resulting static electricity. This was neither an easy nor practical way to generate useful electrical power.

In December 2019, the United States established its new space force: the United States Space Force. A logical step in a globalized and digitized world whose infrastructure depends on satellites in space. This infrastructure is under threat. Also by a resurgence of conflict between East and West. This episode of Spacetime describes how the military conquered space and why the world is in a new arms race in Earth orbit.

Blake Lemoine, the Google engineer fired for violating the company’s confidentiality policy, has now expressed concerns about the risks associated with AI-driven chatbots like Microsoft’s Bing AI.

The latest AI models, according to him, are the most potent technological advancement since the atomic bomb and can alter the course of history fundamentally.

Beijing is also in a position to maintain a monopoly in some of these areas, the report warned.

A cybersecurity technique that shuffles network addresses like a blackjack dealer shuffles playing cards could effectively befuddle hackers gambling for control of a military jet, commercial airliner or spacecraft, according to new research. However, the research also shows these defenses must be designed to counter increasingly sophisticated algorithms used to break them.

Many aircraft, spacecraft and weapons systems have an onboard computer network known as military standard 1,553, commonly referred to as MIL-STD-1553, or even just 1553. The network is a tried-and-true protocol for letting systems like radar, flight controls and the heads-up display talk to each other.

Securing these networks against a cyberattack is a national security imperative, said Chris Jenkins, a Sandia cybersecurity scientist. If a hacker were to take over 1,553 midflight, he said, the pilot could lose control of critical aircraft systems, and the impact could be devastating.

Alan Thompson, AI Consultant and Former Chairman of Mensa International, examines the latest trends in artificial intelligence, as well as its applications to finance, professional services, and military. He discusses the possibility that AI could become sentient and even dangerous with David Lin, Anchor and Producer at Kitco News.
