BBC: Yet another Soyuz rocket launch has failed. After liftoff from Russia’s Plesetsk spaceport on Friday, 23 December, the Soyuz-2 vehicle was unable to put a communications satellite into orbit. It is one of several failed attempts this year, including Phobus-Grunt in November and the Progress cargo spacecraft, which was to take supplies to astronauts aboard the International Space Station, in August. Russia’s problems could severely impact the US, which depends on Russian rockets to carry astronauts to the International Space Station, writes Will Englund for the Washington Post. In his overview article, Englund notes how Russia has tripled its science spending over the past 10 years, “but innovation is losing out to exhaustion, corruption and cronyism.” Twenty years after the collapse of the Soviet Union, Russia is still struggling to bounce back.
