Is deflection a good business tactic?

Politicians are especially deft at deflection, which is the tactic of answering a question with a question that steers the conversation in a different direction. It's not an easy skill, but former President Donald Trump mastered ...

Different neutron energies enhance asteroid deflection

A research collaboration between Lawrence Livermore National Laboratory (LLNL) and the Air Force Institute of Technology (AFIT) investigates how the neutron energy output from a nuclear device detonation can affect the deflection ...

Image: A shadowy selfie taken 280 million km from Earth

On 21 September 2018, 280 million km from Earth, a roughly 1.5 square-metre cube descended towards a primitive space rock. After years of planning and 4 years in flight, this tiny spacecraft captured this 'shadow selfie' ...

Are asteroids humanity's 'greatest challenge'?

Throughout its 4.5-billion-year history, Earth has been repeatedly pummelled by space rocks that have caused anything from an innocuous splash in the ocean to species annihilation.

These space rocks could save the planet

The box was inconspicuous, but Lawrence Livermore National Laboratory (LLNL) postdoctoral researcher Megan Bruck Syal immediately knew its contents: two meteorites around the size of walnuts. They formed about 4.6 billion ...

Could a laser weapon save earth from killer asteroids?

Potentially hazardous asteroids are still looming large in the minds of scientists engaged in planetary defense issues. Numerous strategies describing deflection of near-Earth objects (NEOs) have been proposed, including ...
