When the Japanese Hayabusa mission visited the space rock in 2005 (Hayabusa’s sample return capsule is set to return to Earth on June 13th by the way), it noticed the asteroid was composed of smaller bits of rubble, rather than one solid chunk. Although this isn’t a surprise in itself...
Meteorites: Why study them? What can they teach us about finding life beyond Earth? Universe Today has explored the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, and cosmochemistry, and how this ...
In a flyby of Earth,the Osiris-Rex spacecraftreleased the sample capsule from 63,000 miles (100,000 kilometers) out. The small capsule landed four hours later on a remote expanse of military land, as the mothership set off after another asteroid. “We hav...
