Pentagon to Assemble Nuclear Rocket in Orbit by 2020

Posted by in categories: energy, military

According to the report, the Defence Advanced Research Projects Agency (DARPA) has requested at least $10 million for its Reactor on a Rocket (ROAR) programme.

The Defence Advanced Research Projects Agency intends to assemble a nuclear thermal propulsion (NTP) system in orbit, Aviation Week reported, citing the Pentagon’s 2020 budget.

“The program will initially develop the use of additive manufacturing approaches to print NTP fuel elements… In addition, the program will investigate on-orbit assembly techniques (AM) to safely assemble the individual core element subassemblies into a full demonstration system configuration, and will perform a technology demonstration”, the budget document says.

NASA publishes images of the meteor no one saw

Posted by in categories: energy, military, space

NASA on Friday published satellite photos of a powerful meteor which appeared just above the Bering Sea on December 18 but went unnoticed until months later.

The explosion unleashed around 173 kilotons of energy, more than 10 times that of the atomic bomb blast over Hiroshima in World War II.

The U.S. Military is Buying a Brutal-Looking Powered Exoskeleton

Posted by in categories: cyborgs, military

The partnership could greatly enhance the productivity of a single officer in the field and decrease fatigue or strain — but the USSOCOM didn’t reveal the exact intended use case for the exoskeleton, which lets the wearer heft 200 pounds (90 kg).

Forklift Arms

It’s the latest sign that exoskeletons are finally hitting the mainstream. Automobile manufacturers are already considering the use of simpler exoskeletons on factory floors. And the Food and Drug Administration approved a lower-body exoskeleton last year for use by people with lower limb disabilities.

Project aims to tame noise from supersonic military jets with ‘swirl’ technology

Posted by in categories: engineering, health, military

It’s cliché to describe something very noisy as “louder than a jet engine.” But supersonic jet engines, like those powering fighters flown by the U.S. military, are so much louder than regular jet engines that scientists have a special term for their sound—” broadband shock-associated noise.”

Now, a team of faculty and students from the Department of Aerospace Engineering at the University of Kansas will design and test to cut noise from supersonic military jets. The U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP), the DoD’s environmental science and technology program, is supporting a one-year, $200,000 effort at KU, with the potential to expand that support in the years ahead.

Pentagon Wants to Test A Space-Based Weapon in 2023

Posted by in categories: existential risks, military, particle physics, satellites

Defense officials have asked for $304 million to fund research into space-based lasers, particle beams, and other new forms of missile defense next year.

Defense officials want to test a neutral particle-beam in orbit in fiscal 2023 as part of a ramped-up effort to explore various types of space-based weaponry. They’ve asked for $304 million in the 2020 budget to develop such beams, more powerful lasers, and other new tech for next-generation missile defense. Such weapons are needed, they say, to counter new missiles from China, Russia, North Korea and Iran. But just figuring out what might work is a difficult technical challenge.

So the Pentagon is undertaking two studies. The first is a $15 million exploration of whether satellites outfitted with lasers might be able to disable enemy missiles coming off the launch pad. Defense officials have said previously that these lasers would need to be in the megawatt class. They expect to finish the study within six months.

Deep-Sea Explorers Discover Wreck of WWII Aircraft Carrier USS Wasp

Posted by in category: military

More than 70 years after it was torpedoed and sunk during the World War II Battle of Guadalcanal, the aircraft carrier USS Wasp has been discovered in the Coral Sea.

Wasp was spotted on the seabed, in 14,000 feet of water, by the research vessel (RV) Petrel, part of a research organization established by Microsoft Corp. co-founder Paul Allen, in January.
