Bad Astronomy | Asteroid impacts on Mars heard by NASA InSight lander | SYFY WIRE

On Sept. 5, 2021, NASA's InSight lander "heard" the impact of an asteroid slamming into the surface of Mars — in fact the space rock broke into three pieces, each hitting the planet and creating a crater.

It gets better: The HiRISE camera on Mars Reconnaissance Orbiter (or MRO) found the craters left behind by the impactor .

Countdown to DART: Will We Move an Asteroid? | The Planetary Society

We are less than a week from the DART spacecraft's impact on asteroid moonlet Dimorphos as this episode is published. Mission Coordination Lead Nancy Chabot gives us a status update and a preview of what to expect during the September 26 encounter.

What is the approximate diameter of the crater made by the Deep Impact spacecraft when it impacted comet Tempel-1? Use the estimate enabled by a later spacecraft that flew by.

A History of Tiny Asteroid Impacts Forced Our Moon to 'Wander' on Its Axis : ScienceAlert

"Based on the Moon's cratering history," says planetary scientist Vishnu Viswanathan of NASA's Goddard Space Flight Center, "polar wander appears to have been moderate enough for water near the poles to have remained in the shadows and enjoyed stable conditions over billions of years."

An asteroid and volcano 'double punch' doomed the dinosaurs: study | Space

Major volcanic eruptions could have caused mass extinctions throughout Earth's history, including the one that wiped out the dinosaurs around 66 million years ago. 

Currently, the leading theory to explain the mass extinction that saw the end of the dinosaurs suggests that it was triggered when a massive asteroid impacted Earth in what is now the Chicxulub region of the Gulf of Mexico.

NASA Is About to Deliberately Crash the DART Probe Into an Asteroid: What to Know

NASA's deep space exploration robots are marvels of engineering that are often built to last. You have the Voyager probes, at the end of the solar system, still operating decades after launch .

DART isn't destined for decades of solar system science. The spacecraft launched in November 2021 and, by next week, it will be no more.
