The essential ingredients are carbon atoms, titanium, and a good coating of graphite.
researchers believe they could use that knowledge to build better materials here on Earth.
, an astrophysicist at the Carnegie Institution for Science in Washington, DC, who was not an author of the study.The study authors peered into a unique kind of dust grain with a core of titanium carbide—titanium and carbon, combined into durable, ceramic-like material that’s nearly as hard as diamond—wrapped in a shell of graphite. Sometimes, tens or even hundreds of these carbon-coated cores clump together into larger grains.
Still, that brief flight was enough for the rocket’s components to gain more than a taste of the microgravity that astronauts experience in orbit. One of those components was a contraption inside which scientists could incubate dust grains and record the process., a physicist at Hokkaido University in Japan, and one of the paper’s authors.Just over three hours after launch, including six and a half minutes of microgravity, the rocket landed about 46 miles away from its launch site.
