Northrop Grumman’s Cygnus On Its Way to ISS, But With a Stuck Solar Array
Northrop Grumman successfully launched its Cygnus cargo spacecraft to the International Space Station this morning, but one of the two solar arrays did not deploy. The company is troubleshooting the problem while NASA assesses what issues could arise when berthing Cygnus to ISS in that condition. Cygnus is carrying equipment needed for a spacewalk next week, so those plans could change if berthing is not possible.
