The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.

We don’t know much about the target asteroid of Nasa’s imminent Dart mission, so it’s hard to predict what will happen when we crash into it.
The Double Asteroid Redirection Test is the first planetary defense experiment ever attempted.
Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
Rovers on Mars frequently come across debris – like this heat shield and spring – from their own or other missions.
Discarded pieces of landing gear, crashed spacecraft and wear and tear have produced a lot of debris that is now scattered around the Martian surface.
Astronomers think the most likely place to find life in the galaxy is on super-Earths, like Kepler-69c, seen in this artist’s rendering.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
Artemis I launch has been ‘scrubbed’ a couple of times now. Why is a launch window so important, and what does scrubbing mean, anyway?

Why is humanity going back to the Moon after 50 years? Because we can, and we should.
NASA is going back to the Moon.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.

Will humans be back on the Moon by 2025? It depends on how well the imminent launch of Artemis-1 goes.
Making territorial claims in space is illegal under international law.
The era of lunar resource use is quickly approaching. But with legal and practical issues still looming, nations are starting to think about sustainable ways to mine and protect the Moon.
Private companies have launched dozens of imaging satellites – like the two small boxes in the middle of the photo – into orbit in recent years.
Private satellite companies have boomed in recent years, and many experts have wondered what role they would play in a conflict. They have proved to be invaluable to Ukraine in recent months.

With decades of images and data from the same locations, these satellites can show changes over time, including deforestation, changes in waterways and how loss of trees corresponds to urban heat.
In the excitement, it’s easy to forget the James Webb Space Telescope’s namesake has been the subject of controversy.
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
