"Russian news agencies are quoting a top space official as saying Russia won't permit a U.S. commercial spacecraft to dock with the International Space Station until it is satisfied the ship conforms to safety standards. The California-based Space Exploration Technologies Corp. has asked NASA for permission to send an unmanned cargo capsule to the space station later this year. The hookup also would need Russian clearance."
Keith's note: What a great way to continue a monopoly on access to the ISS. Curiously, the "digital" Soyuz was allowed to dock despite its ongoing problems.
