SpaceX Falcon 9 Launch Schedule Uncertain — Updated

An update from Musk.

SpaceX is still trying to accomplish a static fire on an upgraded Falcon 9 on the launch pad at Cape Canaveral. The company had originally planned a test on Wednesday with a launch on Saturday.

The launch vehicle includes a series of upgrades, including liquid oxygen chilled to a much colder temperature than on previous flights. SpaceX CEO Elon Musk tweeted yesterday that engineers were having issues with this improvement.
