ClockEndGooner writes "A giant coronal mass ejection from the Sun yesterday has resulted in a higher than normal level of radioactivity, and in turn, forced Orbital Sciences to postpone their first mission launch of the Cygnus space truck to the International Space Station. Citing concerns of the effect increased levels of space radiation may have on the Antares launcher and Cygnus avionics, the NASA and Orbital launch team is now evaluating if conditions will improve for a launch on Thursday, which would have Cygnus arriving at the ISS on Sunday morning."
In other ISS news, the Orlando Sentinel is reporting that NASA has gotten approval from the White House to extend the ISS's mission for another four years
, pushing the end date back to 2024. An official announcement is expected later this week.
