Nasa’s Dart probe to smash into asteroid in first Earth defence test | Asteroids

Most mission scientists would wince at the thought of their spacecraft being smashed to smithereens. But for those behind Nasa’s Dart probe, anything short of total destruction will be chalked up as a failure. The $330m (£300m) spacecraft is due to slam head-on into an asteroid about 11m kilometres above the Indian Ocean soon after … Read more

NASA will intentionally crash a spacecraft into an asteroid at 15,000mph on Monday

In just a few days’ time, NASA will intentionally crash a spacecraft into an asteroid at 15,000mph. Such a mission may evoke memories of a Hollywood disaster movie such as Armageddon or Deep Impact, but this is very much real and is actually part of the US space agency’s first ever planetary defence test. Of course, there … Read more

Nasa delays Artemis 1 moon rocket launch again as tropical storm Ian looms | Nasa

Nasa is skipping Tuesday’s launch attempt of its new moon rocket over concerns about a tropical storm headed to Florida that could become a major hurricane. It’s the third delay in the past month for the lunar-orbiting test flight featuring mannequins but no astronauts, a follow-up to Nasa’s Apollo moon-landing program of a half-century ago. … Read more

A New FRB Signal Has Buzzed Nearly 2,000 Times in Just Two Months, Raising a Mystery : ScienceAlert

We have detected a strange new signal from across the chasm of time and space. A repeating fast radio burst source detected last year was recorded spitting out a whopping 1,863 bursts over 82 hours, amid a total of 91 hours of observation. This hyperactive behavior has allowed scientists to characterize not just the galaxy that … Read more

Super-Earths Are Bigger and More Habitable Than Earth, and Astronomers Are Discovering More of the Billions They Think Are Out There

Astronomers now routinely discover planets orbiting stars outside of the solar system— they’re called exoplanets. But in summer 2022, teams working on NASA’s Transiting Exoplanet Survey Satellite found a few particularly interesting planets orbiting in the habitable zones of their parent stars. One planet is 30 percent larger than Earth and orbits its star in … Read more

‘Baby’ island appears in Pacific Ocean after underwater volcano erupts

The new baby island emerged in the southwest Pacific Ocean, where underwater volcanoes are plentiful. One of these submerged volcanoes awoke on September 10, spewing lava, steam, and ash, according to a statement from the NASA Earth Observatory. Just eleven hours after the volcano began to erupt, a new island had emerged above the water’s … Read more

Mars is already TRASHED: Humans have left more than 15,000 pounds of debris on the Red Planet

Humans have left more than 15,000 pounds of trash on Mars in the last 50 years and not a single person has ever stepped foot on the red planet. Cagri Kilic, a postdoctoral research fellow in robotics at West Virginia University, analyzed the mass of all rovers and orbiters sent to Mars and subtracted the … Read more

‘Planetary defence’: NASA targets asteroid in space collision | Space News

After NASA deliberately smashes a car-sized spacecraft into an asteroid next week, it will be up to the European Space Agency’s Hera mission to investigate the “crime scene” and uncover the secrets of these potentially devastating space rocks. NASA’s Double Asteroid Redirection Test (DART) aims to collide with the asteroid moonlet Dimorphos on Monday night, … Read more
