Cygnus Orb-1

Later that day, due to the need for a series of spacewalks to fix a faulty coolant system on the International Space Station, NASA directed Orbital Sciences to stand down the Antares rocket.

[15] NASA Wallops and Orbital Sciences announced the launch attempt on 8 January 2014 was scrubbed due to "an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket's electronic systems are not impacted by a harsh radiation environment".

[15] Orbital later revised this, stating that a more extensive review of the radiation environment found it to be "within acceptable limits" of the Antares program, and that a launch would be attempted on 9 January 2014.

[19] Cygnus was filled with 1,260 kg (2,780 lb) of supplies for the ISS, including science experiments and hardware to expand the research capability of the station, crew provisions and spare parts.

The spacecraft reentered the atmosphere and burned up on 19 February 2014 over the southern Pacific Ocean, disposing of approximately 1,470 kg (3,240 lb) of trash.
