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.

It was almost noon yesterday in Kazakhstan when the MexSat-1 satellite, also called Centenario to celebrate the centenary of the Mexican Revolution, was launched on a Proton-M rocket from the Baikonur Cosmodrome in Kazakhstan. After about 10 minutes, however, something malfunctioned in the rocket’s third stage, causing the loss of the satellite.

A new radio telescope was recently activated in California, based at Caltech’s Owens Valley Radio Observatory (OVRO). It’s the Owens Valley Long Wavelength Array (OV-LWA), a set of 256 small antennas developed by a consortium led by Caltech that includes NASA’s JPL, Harvard University, the University of New Mexico, Virginia Tech, and the Naval Research Laboratory. Its purpose is to observe the entire sky 24/7 at long radio wavelengths.

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.
