General Dynamics’ Stryker Will Counter Drone Swarms With a Microwave Weapon

Posted by in categories: drones, military, robotics/AI

In service since 2,002 the Stryker combat vehicles have been constantly upgraded in light of changing warfare techniques. When deployed in Iraq, these combat vehicles had to be protected from the rocket-propelled grenades but were recently found to be lacking against unmanned aerial vehicles (UAVs) in Europe. As warfare moves at lightning speed from drones to drone swarms, General Dynamics, the manufacturer of Stryker vehicles, is looking to arm the vehicle with a directed energy weapon.

To accelerate the pace of this upgrade, the defense manufacturer has teamed up with Los Angeles-based Epirus Inc., which has developed a counter-electronics system, Leonidas, capable of handling single as well as multiple threats.

Jeff Bezos’ Blue Origin Will Launch an Orbital ‘Space Business Park’

Posted by in categories: business, space travel

We might be witnessing the start of the private space station race.

Dare we say that a new type of space race is heating up? Blue Origin, the space tourism firm founded by billionaire Amazon founder Jeff Bezos, announced a partnership with Sierra Space and Boeing to build and launch a commercial space station called Orbital Reef by the end of the decade, a press statement reveals.

SpaceX to launch Emirati imaging satellite

Posted by in category: satellites

DUBAI, U.A.E. — SpaceX has won a contract to launch an Emirati high-resolution imaging satellite on a Falcon 9 rideshare mission in 2023.

The Mohammed Bin Rashid Space Centre (MBRSC) announced at an Oct. 27 press conference here, held during the 72nd International Astronautical Congress, that it selected SpaceX to launch its MBZ SAT satellite in the second half 2023. The center did not disclose the value of the contract.

Salem AlMarri, deputy director general of MBRSC, said the center looked at several launch providers for the mission. “At the end of the day, we look, for each mission, what is best. For this mission, SpaceX was the best.”

An Ultra-Precise Clock Shows How to Link the Quantum World With Gravity

Posted by in categories: particle physics, quantum physics, space

The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It’s a well-known but perplexing result: Time slows if you’re moving fast.

Gravity does the same thing. Earth — or any massive body — warps space-time in a way that slows time, according to Albert Einstein’s general theory of relativity. If Alice lived her life at sea level and Bob at the top of Everest, where Earth’s gravitational pull is slightly weaker, he would again age faster. The difference on Earth is modest but real — it’s been measured by putting atomic clocks on mountaintops and valley floors and measuring the difference between the two.

Physicists have now managed to measure this difference to the millimeter. In a paper posted earlier this month to the scientific preprint server arxiv.org, researchers from the lab of Jun Ye, a physicist at JILA in Boulder, Colorado, measured the difference in the flow of time between the top and the bottom of a millimeter-tall cloud of atoms.

Tube-in-tube structure going strong

Posted by in category: materials

Similar to grass stems, Lawrence Livermore National Laboratory (LLNL) scientists have created nanostrut-connected tube-in-tubes that enable stronger low-density structural materials.

Porous materials with engineered stretching-dominated lattice designs, which offer attractive mechanical properties with ultra-light weight and large surface area for wide-ranging applications, have recently achieved near-ideal linear scaling between stiffness and density.

In the new research, the team developed a process to transform fully dense, 3D-printed polymeric beams into graphitic carbon hollow tube-in-tube sandwich structures, where, similar to grass stems, the inner and outer are connected through a network of struts. The research is on the cover of the Oct. 25 issue of Nature Materials.
