A little while ago, NASA astronaut Terry Virts, Russian cosmonaut Anton Shkaplerov, and Italian astronaut Samantha Cristoforetti, returned to Earth on the Soyuz TMA-15M spacecraft, landed without problems in Kazakhstan. The three of them spent nearly six and a half months on the International Space Station, where they arrived on November 24, 2014. They were initially part of the Expedition 42, in the second half of their stay they were part of Expedition 43 with Terry Virts as Station commander.
The journal “Astronomy and Astrophysics” will publish an article that illustrates a discovery about the atmosphere of the comet 67P/Churyumov-Gerasimenko generated by the sublimation of the ice it contains. Water, but also carbon dioxide, are turned into steam but thanks to the instrument Alice of the space probe Rosetta it was possible to discover that these molecules get broken and that this happens in two stages.
The scientists of the Rosetta space probe’s OSIRIS camera’s team discovered a curious rock formation in the region called Aker of the comet 67P/Churyumov-Gerasimenko. They look like the balancing rocks existing in various places on Earth and precisely these are three rocks that seem to have very little contact with the comet’s surface.
The schedule for the International Space Station crew rotation has been officially changed. Following the mishap with the Russian spacecraft Progress M-27M it was decided to postpone the launch of the next three members so the three ones of the Expedition 42/43 – Samantha Cristoforetti, Terry Virts and Anton Shkaplerov – will remain on the Station at least until the beginning of June.
Between April 28 and 29, 2015 a solar flare produced a filament that spread to a really huge distance. The result is that the images of the space probe SOHO (Solar and Heliospheric Observatory) that captured the filament, to include it cover a wide area of 45 million kilometers (about 30 million miles).
