‘This one’s for the dinosaurs’: how the world reacted to Nasa’s asteroid smashing success | Space

The crashing of a spacecraft is, for once, a cause for celebration. The Dart (Double Asteroid Redirection Test) mission on Tuesday marked humanity’s first ever attempt at moving an asteroid in space. Scientists at Nasa and Johns Hopkins University applauded and hugged each other on Tuesday after Dart, the size of a vending machine, successfully … Read more

Nasa Dart mission: Spacecraft slams into asteroid in first-ever planetary defence effort

At 7.14pm EDT, Nasa made history by slamming a spacecraft into an asteroid, marking the first time life on Earth has altered the course of a heavenly body. Nasa’s Double Asteroid Redirection Test spacecraft, or Dart, slammed into the asteroid Dimorphos at 14,400 miles per hour to test whether the impact can alter the asteroid’s … Read more

Mars may have experienced episodic FLOODING millions of years ago, radar image reveals

A new image of the surface of Mars has revealed the planet may have experienced episodic flooding millions of years ago. The Zhurong Mars rover has returned ground-penetrating radar data of the Utopia Planitia basin – an impact crater thought to have once hosted an ancient ocean. The image was constructed from the data by scientists from … Read more

Artificial intelligence reduces a 100,000-equation quantum physics problem to only four equations

A visualization of a mathematical apparatus used to capture the physics and behavior of electrons moving on a lattice. Each pixel represents a single interaction between two electrons. Until now, accurately capturing the system required around 100,000 equations—one for each pixel. Using machine learning, scientists reduced the problem to just four equations. That means a … Read more

Nasa prepares to crash spacecraft into asteroid in ‘planetary defense test’ – live | Nasa

Here’s a few more details from Nasa about the target of tonight’s “planetary defense test”, the 525ft (160 metre) diameter Dimorphos. It’s length is about the same of 1.5 football fields, and is the smaller of two asteroids in a double-asteroid system that the agency deems perfect for the mission. Dimorphos orbits the larger asteroid, … Read more
