Hayabusa2 Races Toward Asteroid 1998 KY26 as Researchers Study Its Motion
Japan’s Hayabusa2 spacecraft is currently racing toward a target that defies standard orbital physics. As the probe travels toward the near-Earth object 1998 KY26, researchers are struggling to identify the source of the asteroid’s anomalous acceleration. "Our temperature model results indicate that the water outgassing rate on 1998 KY26 would be too high to maintain … Read more
