Asteroid Ryugu is a “Fragile Rubble Pile”

When Japan’s Hayabusa 2 spacecraft arrived at asteroid Ryugu in June 2018, it carried four small rovers with it. Hayabusa 2 is primarily a sample-return mission, but JAXA (Japan Aerospace Exploration Agency) sent rovers along to explore the asteroid’s surface and learn as much as they could from their visit. There’s also no guarantee that the sample return will be successful.

They chose Ryugu because the asteroid is classified as a primitive carbonaceous asteroid. This type of asteroid is a desirable target because it represents the primordial matter that formed the bodies in our Solar System. It’s also pretty close to Earth.

The sample from Ryugu, which will make it to Earth in December 2020, is the big science prize from this mission. Analyzing it in Earth-based laboratories will tell us a lot more than spacecraft instruments can. But the rovers that landed on Ryugu’s surface have already revealed a lot about Ryugu.

Watch this Amazing Video of Hayabusa 2 Picking Up a Sample from the Surface of Ryugu

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.

The Japanese asteroid-hunter had another photo opportunity when it dropped a target marker on asteroid Ryugu

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.

Here’s the Video of Hayabusa2 Bombing Asteroid Ryugu

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.

Japan’s Hayabusa2 spacecraft has completed an important part of its mission to asteroid Ryugu. The spacecraft descended to the surface of the asteroid to collect two samples with its sampling horn. We don’t know for sure if samples were successfully collected, but all indications are that the sampling mission went well.

Japan’s Hayabusa2 is About to Shoot Up the Surface of Ryugu with Tiny Impactors so they can Collect a Sample

Japan’s Hayabusa2 mission is about to get down to business. After arriving at asteroid Ryugu at the end of June 2018, and dispatching its tiny rovers to the surface, the spacecraft is about to approach the surface of the asteroid and get some samples.

Weekly Space Hangout: Jan 23, 2019: Marco Parigi, Asteroid/Comet Whisperer

Hosts:
Fraser Cain (universetoday.com / @fcain)
Dr. Morgan Rehnberg (MorganRehnberg.com / @MorganRehnberg & ChartYourWorld.org)

Marco is a self-declared Asteroid/Comet whisperer. He’s dabbled in citizen science for years, and he most recently flagged many changes on 67P when this was directly requested through the Rosetta Blog:
http://blogs.esa.int/rosetta/2016/06/03/the-changing-comet-call-for-contributions/ He is currently working on finding evidence for out gassing and stretch at Ultima Thule (similar to 67P), predicting an outburst for RYUGU when an impactor is fired into it in March, and helping with the engineering and physics of a propellant-less thruster based on capacitors called the IMFAB. Marco can be found on twitter at @marcoparigi1.

The Path that MASCOT Took Across Asteroid Ryugu During its 17 Hours of Life

The tiny hopping-robot MASCOT completed its 17 hour mission on the asteroid Ryugu in early October. Now the German Aerospace Center (DLR) has released an image of MASCOT’s path across the asteroid. Surprised by what MASCOT found on the surface, they’ve named the landing spot “Alice’s Wonderland.”
