At the 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences in National Harbor, Maryland, A research was presented about Phobos, a moon of Mars. Terry Hurford of NASA’s Goddard Space Flight Center led a team of scientists who analyzed the grooves on Phobos surface. The conclusion is that these are the first signs of structural failure that will lead to the destruction of this moon.
NASA’s New Horizons mission team is presenting the latest findings on the dwarf planet Pluto at the 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences in National Harbor, Maryland. The data collected by the spacecraft during its July 14, 2015 flyby made it possible to identify possible cryovolcanoes. Data on small moons of Pluto are limited but suggest more and more that at least Cerberus and Hydra are the result of the merger of two or more asteroids.
Two articles, one published in “Journal of Geophysical Research: Space Physics” and one published in the journal “Icarus”, describe a research on ultraviolet auroras detected on Mars by ESA’s Mars Express space probe. Jean-Claude Gérard and Lauriane Soret of the University of Liege, Belgium, led a team of scientists who examined ten years of data that were analyzed to understand the mechanisms of creation of these auroras.
Two magazines host a number of articles describing the results of a year of the mission of NASA’s MAVEN space probe, “Science” and “Geophysical Research Letters”. The conclusions about why Mars lost most of its atmosphere were also explained in a NASA press conference held yesterday. Simply put, it was solar wind, which could take away the atmosphere thanks to the absence of a protective magnetic field transforming a planet that was originally similar to Earth in the desolate red planet we know today.
A few hours ago the first test launch of the Super Strypi rocket in the mission referred to as ORS-4 was conducted but ended in failure. The rocket regularly blasted off from the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii but after about a minute lost control and after a few seconds broku up with the consequent destruction of the 13 satellites it was supposed to put in orbit.
