atmosphere in 1995. During the parachute-assisted descent, contact with the probe was lost when it overheated. The probe melted in the following hours. The main spacecraft stayed in orbit around Jupiter until 2003 when it was deliberately sent into Jupiter's atmosphere by ground controllers as a measure to prevent contamination of the moon EuropaEuropa (moon)Europa Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and probably has an iron core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is composed of ice and is one of the smoothest in the Solar System. This surface is striated by cracks and...
