This is slightly older news, but the shuttle Discovery’s launch that was set for Wednesday has been posponed due to a hydrogen gas leak. The new launch date has been set for Monday the 16th. Discovery is slated to deliver the last truss segment and the last set of solar panels to the International Space Station. A replacement part to the urination recycling unit delivered in November is also supposed to go up. The solar panels and urination system will allow the ISS crew to grow from 3 to 6 persons.
