SpaceX ISS Cargo Mission CRS-11 Live Stream: Watch Falcon 9 Take Off On NASA Mission, If Weather Permits

Elon Musk's company SpaceX will attempt to launch a Falcon 9 rocket Saturday evening, in a bid to send a refurbished Dragon cargo spacecraft to the International Space Station (ISS). The CRS-11 mission is the eleventh for the commercial space company and was originally scheduled for Thursday evening, but had to be postponed due to weather conditions. The weather could play spoilsport once again Saturday, which has an instantaneous launch window at 5:07 p.m. EDT. According to forecast by meteorologists with the U.S. Air Force 45th Weather Squadron, announced Friday morning, there was a 60 percent chance of favorable weather at the time of the planned launch. That forecast was worse than the 70 percent favorable forecast announced Thursday night. "The primary weather concerns for Saturday's launch are anvil clouds, cumulus clouds and flight through precipitation," the forecast announcement on NASA's website said.
