Post navigation White sharks have an unexpected friend – the pilot fish. The pilot fish can act as a guardian of the white shark, eating parasites from its skin and even chasing away predators. This peaceful relationship between white sharks and pilot fish supports the idea that some shark species can be very social. ESA’s Hera and Juventas-Jura mission seeks to place two small spacecrafts in lunar orbit to investigate the surface of the moon. They will create 3D images of asteroids by using radar instruments to provide information about their mass, shape, and origins. Ultimately, the mission aims to help us better understand the history and formation of the Solar System.
