An article published in the magazine “The Astronomical Journal” describes a research on the exoplanet 55 Cancri e. This super-Earth is one of the most studied among the planets in other solar systems but its extreme characteristics and the often experimental nature of the studies carried out provided partial and sometimes contradictory results. Now a analysis of data gathered using NASA’s Spitzer Space Telescope convinced a team of researchers that 55 Cancri e has an atmosphere and could have a composition similar to that of the Earth.

A little while ago the JPSS-1 satellite blasted off atop a Delta 2 rocket in its 7920 configuration from the Vandenberg base. After almost one hour it successfully separated from the rocket’s last stage and entered a Sun-synchronous orbit, meaning it will fly over every area of ​​the Earth’s surface at the same local time, at an altitude of about 824 kilometers (512 miles).

A little while ago Orbital ATK’s Cygnus spacecraft blasted off atop an Antares rocket from the Mid-Atlantic Regional Spaceport (MARS), part of NASA’s Wallops Flight Facility (WFF) on Wallops Island. After about nine minutes it successfully separated from the rocket’s last stage went en route to its destination. This is its eighth official mission, called Orbital-8 or simply Orb-8 but also CRS OA-8, to transport supplies to the International Space Station for NASA.

NASA has published a series of images taken by its Mars Rover Curiosity in the Gale Crater area of Mars called the Vera Rubin Ridge created putting together photos taken using filters that allow the mission scientists to identify some minerals. The instruments that have this capability are the MastCam (Mast Camera) and ChemCam (Chemistry and Camera). On this occasion, the MastCam allowed to highlight an iron oxide called hematite.
