“Occator Crater on Ceres is home to the brightest area on the entire dwarf planet. At 57 miles (92 kilometers) wide and 2.5 miles (4 kilometers) deep, Occator displays evidence of recent geologic activity. NASA’s Dawn mission found that the bright spots may have been produced by upwelling of salt-rich liquids after the impact that formed the crater. Pan and zoom as you fly over the crater with Dawn in this 360-degree animation made with observations from the spacecraft.”

ESA dixit:

“As a result of a deep cracking cutting across the Larsen C ice shelf, a huge iceberg was spawned on 12 July 2017. Europe’s Copernicus Sentinel-1 mission was used to monitor the rift’s progress, a network of fractures in the ice and the calving event. Since then, the large tabular iceberg – known as A68 – has drifted about 5 km from the ice shelf. Images from Sentinel-1 also show that a cluster of more than 11 smaller icebergs have now also formed, the largest of which is over 13 km long. These ‘bergy bits’ have broken off both the giant iceberg and the remaining ice shelf.

ESA dixit:

“Having detailed knowledge of the shape of the seafloor is essential for generating nautical charts for navigation. It is also needed for exploration, fishing, coastal management and for understanding ocean currents that transport heat, nutrients and pollutants. While mapping the seafloor was traditionally carried out using sonar on ships, optical satellite data provide global, high-resolution maps that show ridges, valleys and sediments.”

“On 18 September 2017, ESA astronaut Paolo Nespoli shot this beautiful time-lapse showing the Moon rising above the Earth’s horizon together with Mercury, Mars, the star Regulus, and Venus. ESA astronaut Paolo Nespoli is currently working and living on board the International Space Station as part of his long duration Vita mission.”

NASA dixit:

“NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days from launch, they are confident the shoebox-sized satellite Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science. Dellingr will study how the ionosphere, a region in Earth’s upper atmosphere, interacts with the Sun. Before launch, Dellingr is required to visit to the Magnetic Test Facility at NASA Goddard to test the spacecraft’s magnetometers – key instruments for measuring the direction and strength of the magnetic fields that surround Earth. The spacecraft is scheduled to launch this August aboard a SpaceX Falcon 9 rocket to the International Space Station where it will be deployed later into a low-Earth orbit.
