The threat from near-Earth asteroid 2024 YR4 may have subsided, but discoveries of other hazardous space rocks are set to ...

"Sending multiple smaller impactors not only results in a higher asteroid push but also potentially saves operational cost and increases tactical flexibility for deflection." Ferrari agrees with ...

In reality, even as the near-Earth asteroid 2024 YR4 was moving away, ground-based telescopes were able to gather enough observations to get a better handle on its orbit. So we can safely take a deep ...

William Lucas, who has died aged 102, was the director of Nasa’s Marshall Space Flight Center in Huntsville, Alabama, the ...

The ‘gravity tractor’ method of asteroid deflection involves flying a spacecraft close enough to an asteroid so its gravitational attraction gradually pulls the body off course ...

The Hera probe has swung around Mars, using the planet’s gravitational pull to fling itself toward its asteroid target.

Deimos is about 15,000 miles from Mars. Scientists have previously speculated that it may actually be a piece of asteroid, not a moon. Hera got as close as 1,000 kilometers, or about 620 miles ...

The worldwide tech leading Dutch firm, cosine, is making a big impact in space exploration. The company is playing a key role in the European Space Agency’s (ESA) Hera mission by providing a ...

Only one asteroid deflection test has ever taken place in space. In 2022, Nasa sent its Dart (Double Asteroid Redirection Test) spacecraft to crash into Dimorphos, a 525ft-wide “moonlet” which ...
