A new video shows Japan’s Hayabusa 2 sample return spacecraft collecting samples from asteroid Ryugu. The spacecraft has been at Ryugu for months now, and it’s all been leading up to this. In the video, you can clearly see airborne asteroid dust and particles swirling around in the low gravity.Continue reading “Watch this Amazing Video of Hayabusa 2 Picking Up a Sample from the Surface of Ryugu”
Why report on an asteroid that has no chance of hitting Earth? Because this asteroid, known as 2006 QV89, has a history. A history of being kind of hard to track.Continue reading “Asteroid 2006 QV89 Now Has a 0% Chance of Hitting Earth in September”
It looks like a poster of the famous Hubble Deep Field, marked with white streaks by a child, or put away carelessly and scratched in the process. But it’s not. The white streaks aren’t accidents; they’re the paths of asteroids.Continue reading “Hubble is the Ultimate Multitasker: Discovering Asteroids While it’s Doing Other Observations”
The Japanese Aerospace Exploration Agency‘s (JAXA) has made some impressive feats in recent years. Roughly one year ago, and following in the footsteps of its predecessor, their Hayabusa2 spacecraft successfully rendezvoused with a Near-Earth Asteroid (NEA) – 162173 Ryugu. Since then, it has been collecting samples from the surface in the hopes of learning more about the formation and evolution of the Solar System.
Just a few months after the spacecraft created an artificial crater with an anti-tank warhead, the spacecraft has once again descended close to the asteroid to drop another target marker. This maker, a reflective sphere that contains the names of people who’ve supported the mission, will provide a visual guide as the spacecraft attempts to collect its second sample of material from the asteroid’s surface.Continue reading “The Japanese asteroid-hunter had another photo opportunity when it dropped a target marker on asteroid Ryugu”
Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo!Continue reading “Don’t Worry About Asteroid 2006QV89. There’s Only a 1 in 7000 Chance It’ll Hit the Earth in September”

Remember when Orson Welles’ 1938 radio show called “The War of the Worlds” fooled people into thinking that Earth was actually being invaded? That was fun.
Now, the ESA (European Space Agency) is tempting fate by live-tweeting the hypothetical approach of the hypothetical asteroid 2019PDC and hypothetically planning a hypothetical response to this hypothetically destructive asteroid. In their hypothetical scenario, 2019 PDC has a 1 in 10 chance of striking Earth in 2029. And you can follow the action on Twitter.Continue reading “The World’s Space Agencies are Responding to a Hypothetical Asteroid Impact. You Can Watch it all Unfold Online.”
As part of its mission to explore the Near-Earth Asteroid (NEA)
162173 Ryugu, the Japan Aerospace Exploration Agency‘s (JAXA) Hayabusa2 spacecraft recently dropped a “bomb” on the asteroid’s surface. This explosive package, known as the Small Carry-on Impactor (SCI), was specifically designed to create a crater in the surface, thus exposing the interior for analysis.
The deployment of the SCI took place on April 5th, exactly six weeks after the spacecraft collected its first sample from the surface. Last Sunday, (April 21st, 2019), JAXA provided the video of the “bombing run” via the mission’s official twitter account. This was followed four days later by images of the crater that resulted, which revealed darker material from the interior that was now exposed to space.Continue reading “Here’s the Video of Hayabusa2 Bombing Asteroid Ryugu”
Imagine a time in the Solar System’s past where the asteroids were not solid rock, but blobs of molten iron. It sounds strange, but that may have been the case. And in the right conditions, some of those asteroids would have sprouted volcanoes. One of those asteroids, Psyche, is the destination for a NASA mission.Continue reading “Metal Asteroid Psyche Might Have Had Volcanoes of Molten Iron”
It’s become something of an action movie cliche: an asteroid is hurling towards Earth, its impact will cause a mass extinction, and the only hope for humanity is a ragtag group of astronauts and average Joes who will fly to the asteroid and blow it to pieces using nukes. The idea has been explored so many times by Hollywood that it seems like this is actually something space agencies have planned.
And in truth, they are, though the execution may be a little more sophisticated. For decades, space agencies have considered various methods for destroying asteroids that threaten Earth. But according to a new study led by researchers from John Hopkins University, incoming asteroids may be harder to break apart than we thought.Continue reading “Sorry Hollywood, it’s Going to Take a Lot More to Destroy an Asteroid”
