The dwarf planet Ceres Thrills as a dying visitor ends

Ceres is the Queen of the Belt 39; asteroids. His first land visitor approaches his last days in a spectacular style. Dawn's director of mission and chief engineer, Marc Rayman, returns with great images taken just 35 kilometers or 22 miles above the dwarf planet, and a glimpse of the last days of the spacecraft. Bruce Betts, chief scientist of the Global Society, has a summer guide on the night sky, looks at the history of space exploration and delivers another document on random space. He and Mat Kaplan also have a new space issue for listeners.

Crater

This simulated perspective view shows the Occator crater, measuring 92 miles (92 miles) across and 2.5 miles (4 kilometers) deep, which contains the brightest area of ​​Ceres. This area has attracted keen interest since Dawn's approach to the dwarf planet early 2015. This north-facing view was made from images of low-level orbit mapping. altitude of Dawn, 385 kilometers above Ceres. The still mysterious bright regions are now known to be sodium carbonate.

Ceres Limb

En route to its final final orbit, NASA's Dawn spacecraft observes Ceres and returns new compositional data (infrared spectra) and images of the surface of the dwarf planet, such as this dramatic image of the Ceres member

Juling Crater

This view of NASA's Dawn mission shows where ice has been detected in the north wall of Ceres' Juling Crater, which is in almost permanent shadow. This simulated perspective view was made using images of the low-altitude mapping orbit of Dawn, 240 miles (385 kilometers) above Ceres
