Russia has fixed Site 31 at Baikonur Cosmodrome, the only pad supporting the nation's human spaceflight missions. It had been out of commission since late November.
Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we’ve found so far - which in turn makes them interesting for astrobiological surveys. However, there’s a catch - astrobiologists aren’t sure the light from these stars can actually support oxygen-producing life. A new paper, available in pre-print on arXiv, by Giovanni Covone and Amedeo Balbi, suggests that they might not - when it comes to stellar light, quality is just as important as quantity. And according to their calculations, Earth-like biospheres are incredibly difficult to sustain around red dwarfs.
