Asteroid which whizzed past Earth exposes ‘blind spot’ in our planetary defence
Astronomers have warned that an asteroid that whizzed past Earth harmlessly last week has highlighted a blind spot in our ability to spot dangerous space rocks.
"How many natural hazards are there that we could actually do something about and prevent for a billion dollars? There's not many."
Rubble pile asteroid is 4.2 billion years old and nearly indestructible
Based on just three particles of dust, Australian researchers have determined that a near-Earth asteroid is 4.2 billion years old — and practically indestructible.
The knowledge gap: Asteroids can broadly be divided into two types: monolithic (one big rock) or rubble pile (many rocks held together by gravity).
The Space Review: Our solar system is filled with asteroids that are particularly hard to destroy
Well, maybe. But there appears to be one type of asteroid that might be particularly hard to destroy.
In our new study published last week in the Proceedings of the National Academy of Sciences , we discovered that rubble pile asteroids are an extremely resistant type of asteroid and hard to destroy by collision.
Asteroid mining startup AstroForge to launch first missions this year - SpaceNews
WASHINGTON — A startup with plans to mine asteroids for metals says it will launch its first two missions this year, including one that will fly by a near Earth asteroid.
AstroForge announced Jan. 24 that it will launch a cubesat into low Earth orbit in April to test its refinery technologies.
NASA's Record-Breaking Lucy Spacecraft Has a New Asteroid Target

The Lucy team realized that, by adding a small maneuver, the spacecraft would be able to get an even closer look at this asteroid. So, on January 24, the team officially added it to Lucy's tour as an engineering test of the spacecraft's pioneering terminal tracking system.

Psyche is made up of mostly iron and nickel, unlike other asteroids which tend to be mostly rock and ice.
However, it is one of the largest asteroids in the solar system and, with an average diameter of 220km, it makes up one per cent of our galaxy's asteroid belt.
Asteroid warning! 239-foot asteroid discovered speeding towards Earth by NASA | Tech News
Asteroids have time and again impacted Earth and changed the course of history. Some of these space rocks even triggered an extinction-level event. One of the major asteroid-related events in history was when one struck the Earth nearly 65 million years ago.
Although nearly not as dangerous, NASA has warned that another asteroid is heading for a close approach with Earth today.
TOWN TRADITIONS: Searching For Clues To Healdsburg's Asteroid Mystery | Healdsburg, CA Patch
HEALDSBURG, CA — Ten years ago, a geologic discovery in Healdsburg changed how Sonoma State University geologists look at the Northern California landscape.
A resident donated a box of strange-looking stones, running from palm-sized to pebble-sized, many oval-shaped stones with strange pitting and even charred-looking exteriors. When held to the light, many are opaque, like dark obsidian glass.
Asteroid's sudden flyby shows blind spot in planetary threat detection | Technology News,The ...
The discovery of an asteroid the size of a small shipping truck mere days before it passed Earth on Thursday, albeit one that posed no threat to humans, highlights a blind spot in our ability to predict those that could actually cause damage, astronomers say.
NASA for years has prioritized detecting asteroids much bigger and more existentially threatening than 2023 BU, the small space rock that streaked by 2,200 miles from the Earth's surface, closer than some satellites.
