NASA has signed up to test SpinLaunch's extraordinary whirl 'n' hurl space launch technology, which accelerates a launch vehicle to hypersonic speeds using an electric centrifuge instead of a rocket, ...

SpinLaunch has released on-board footage from its eighth suborbital flight test, giving us a unique opportunity to imagine what it'd be like to be hurled skyward out of a centrifugal accelerator at ...

The idea sounds like pure science fiction: a giant cannon that hurls satellites toward orbit at 28,400 km/h, using raw kinetic energy instead of towering rockets. Yet a new generation of space ...

Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

I have kind of a mental disconnect when trying to understand how orbits work. I know, from doing a lot of reading, that a spacecraft in orbit around a body like Earth can increase its orbital height ...

DULLES, Va.--(BUSINESS WIRE)--Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced today that the company was awarded a $16 million contract with options for the ...

Orbital-free density functional theory (OFDFT) represents a promising reformulation of quantum mechanics for materials and molecular simulations. By expressing the kinetic energy solely as a ...

DULLES, Va.--(BUSINESS WIRE)--Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, announced today that the M829E4 Advanced Kinetic Energy 120mm tactical tank cartridge ...
