A Cygnus cargo spacecraft arrived at the International Space Station Thursday morning after a one-day delay. The station’s robotic arm grappled the NG-23 Cygnus spacecraft at 7:24 am EDT (1124 GMT), and will berth the spacecraft to the Unity module later today. The Cygnus was scheduled to arrive at the station Wednesday morning but suffered early shutdowns of its main engine during two orbit-raising maneuvers on Tuesday. NASA and Northrop Grumman later found that a “conservative safeguard in the software settings” caused the shutdowns and not a problem with the thruster itself.
