Plans to launch a private rocket to the International Space Station Wednesday were delayed due to a huge solar flare, according to NBC News.
The flare erupted from a sunspot seven times the size of the earth Tuesday at 1:32 p.m. EST. It followed a series of recent sun storms.
Orbital Sciences called off the scheduled launch of a cargo delivery flight to the ISS, "due to an unusually high level of space radiation," officials said in a statement.
The launch has been delayed multiple times and was originally scheduled to take off in mid-December.
NBC reports that the solar flare poses no threat to the six-man crew on the ISS.
