An article published in the journal “Geophysical Research Letters” describes a research on the implications of multiple asteroid impacts on the Moon some four billion years ago. Using data collected by NASA’s GRAIL (Gravity Recovery and Interior Laboratory) twin space probes, a team of scientists led by MIT (Massachusetts Institute of Technology) discovered a significant porosity in the lunar surface and a network of large seams below it.
A few hours ago, cosmonauts Gennady Padalka and Aidyn Aimbetov and Danish astronaut Andreas Mogensen came back to Earth on the Soyuz TMA-16M spacecraft, landed without problems in Kazakhstan. Padalka spent just over five months on the International Space Station, where he arrived on March 28, 2015 as part of Expedition 43. Aimbetov and Mogensen spent only a few days on the Station, where they arrived on September 4, 2015.
NASA has released a new image of the now famous white spots of Ceres, one of the most mysterious geological features found on this dwarf planet. The Dawn space probe is currently mapping its surface from an altitude of 1,470 km (915 miles) and that allowed to take pictures much more detailed than the ones previously available. These new images have a resolution of 140 meters (450 feet) per pixel and are providing new information about the white spots waiting for in-depth analyzes.
In recent days, the Japanese Suzaku space observatory has been deactivated. On August 26, 2015, JAXA, the Japanese space agency, communicated the decision to terminate the mission of this satellite specialized in X-ray astronomy. Communications between the mission control center and Suzaku had become intermittent since June 1, 2015 and JAXA, after trying to restore them, decided to start the deactivation procedures.
ESA has released an image created using data from the Planck Surveyor satellite offering a very special portrait of an interstellar filament and the Magellanic Clouds. Those are two dwarf galaxies that are part of the Milky Way’s neighborhood and Planck detected the dust between the stars within them during its mission. The main purpose of this satellite was to study the cosmic microwave background radiation (CMB or CMBR), but the data collected are also useful to map the galaxies’ dust and magnetic fields.
