Small fragments of carbon-rich asteroids too fragile to survive atmospheric entry

Ryugu and other asteroids of the common “C-class” consist of more porous material than was previously thought. Small fragments of their material are therefore too fragile to survive entry into the atmosphere in the event of a collision with Earth. This has revealed the long-suspected cause of the deficit of this meteorite type in finds on Earth. Researchers at the German…

Japan’s Hayabusa2 Probe Makes Second Touchdown On Distant Asteroid

Japan’s Hayabusa2 probe touched down on a distant asteroid on Thursday, the space agency said, on a mission to collect samples that could shed light on the history of the solar system. The Japan Times reports: “The control room received Doppler data showing that the probe appears to have touched down successfully,” Japan Aerospace Exploration Agency spokesman Takayuki Tomobe said. “But…

Hayabusa2 drops target marker at asteroid Ryugu

The Japanese Aerospace Exploration Agency (JAXA) has made some impressive feats in recent years. Roughly one year ago, and following in the footsteps of its predecessor, the Hayabusa2 spacecraft successfully rendezvoused with a near-Earth asteroid (NEA) called 162173 Ryugu. Since then, it has been collecting samples from the surface in the hopes of learning more about the formation and evolution of…

Earth vs. asteroids: humans strike back

Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan’s Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu. A much bigger asteroid impact is planned for the coming decade, involving an international…
