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 Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt, DLR) have come to this conclusion in a scientific paper published in the journal Nature Astronomy. The results are based on high-resolution measurements of the surface temperature with the DLR radiometer MARA on board the German-French Mobile Asteroid Surface Scout (MASCOT) lander. On 3 October 2018, as part of the Japanese Hayabusa2 mission, MASCOT descended onto the almost one-kilometre-diameter asteroid Ryugu and sent spectacular images and physical measurements from the surface back to Earth.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2019-07-small-fragments-carbon-rich-asteroids-fragile.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Small fragments of carbon-rich asteroids too fragile to survive atmospheric entry<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ryugu and other asteroids of the common &#8220;C-class&#8221; consist of more porous material than was previously thought.
