NASA published the first topographic maps of the dwarf planet Ceres made using data collected by its Dawn space probe. They show a very diverse surface, full of craters and mountains with differences between the bottom of the craters and the mountain peaks that can reach 15 kilometers (about 9 miles). Meanwhile, the IAU (International Astronomical Union) approved a series of names for various geological features of Ceres.

In recent days, the Mars Rover Curiosity deviated from its programmed route to examine a rock particularly rich in silica. It’s a material composed of silicon and oxygen common in terrestrial rocks in the form of quartz. On Mount Sharp, where Curiosity is working, on its way it took a sample near the area called “Marias Pass”. The results of the analysis were so interesting that the mission team decided to turn it back.

The scientists working at NASA’s New Horizons mission keep on analyzing the photographs that the spacecraft is sending after its July 14, 2015 flyby with the dwarf planet Pluto. The ones received in recent days show that in the heart-shaped area there are flowing glaciers and that in the atmosphere there are thick layers of haze that reach an altitude of 130 kilometers (about 80 miles).

NASA announced the discovery of the planet Kepler-452b made using the Kepler space telescope. It has an orbit similar to that of the Earth around a star similar to the Sun. This puts it well within the habitable zone of its star system because the star Kepler-452 is just a little bigger and brighter than the Sun so if on the planet Kepler-452b there was an atmosphere similar to the Earth’s, water could exist in liquid form.

A few hours ago the Soyuz TMA-17M spacecraft blasted off from the Baikonur Cosmodrome in Kazakhstan and after almost exactly six hours reached the International Space Station carrying Kjell Lindgren, Oleg Kononenko and Kimiya Yui. The Soyuz traveled on the fast path normally used. There were a couple of little problems because one of the spacecraft’s solar panels didn’t deploy and after the arrival it took longer than expected to balance the air pressure with the Station but in the end everything went well.
