In an unfortunate twist of fate, the first non-SpaceX commercial payload since the Falcon 9 anomaly has malfunctioned! Northrop Grumman Cygnus, packed with vital ISS supplies, has failed to enter the proper trajectory twice!

Perhaps the headline should have been Northrop Grumman's Cygnus spacecraft has a hiccup? 

The issues were resolved and it is scheduled to berth at ISS tomorrow.

The Falcon 9 second stage issue was because of a change a customer requested, an extra oxygen sensor's line cracked and allowed an oxygen leak.

"Cygnus spacecraft suffers glitches after launch

>

In a NASA statement issued nearly six hours after liftoff, the agency said that the spacecraft failed to perform a maneuver called targeted altitude burn, or TB1, 42 minutes after liftoff “due to a late entry to burn sequencing.” The burn was rescheduled for 50 minutes later, but also did not take place because of a “slightly low initial pressure state” in the engine.

“Cygnus is at a safe altitude, and Northrop Grumman engineers are working a new burn and trajectory plan,” NASA stated, adding that the plan should still allow Cygnus to arrive for a capture by the station’s robotic arm at 3:10 a.m. Eastern Aug. 6. NASA added that solar array deployment was completed about three hours after liftoff, as expected.
