Robert PearlmanLaunch abort! Today's (Feb. 9) launch attempt has been scrubbed. From Northrop Grumman, via Twitter:
We have aborted today's launch attempt of our NG-13 mission due to off-nominal data from the ground support equipment.
Robert PearlmanNorthrop Grumman update
Northrop Grumman scrubbed tonight's [Feb. 9] Antares launch after off-nominal readings from a ground support sensor. Northrop Grumman and NASA have set the next launch attempt to no earlier than February 13 at 4:05 p.m. EST [2105 GMT], due to an unfavorable weather forecast over the next two days, and time required to address the ground support issue. Teams will refresh 24-hour late load cargo the day before. The Antares rocket and Cygnus spacecraft remain healthy.
Robert PearlmanNASA update
Northrop Grumman and NASA have set the next launch attempt for [Friday] Feb. 14 at 3:43 p.m. EST [2043 GMT] to take advantage of an improved weather forecast, to provide time for testing the replaced ground sensors and to allow for refresh of critical late load science. The weather forecast calls for 80% favorable weather conditions.

NASA Science, Cargo Heads to Space Station on Northrop Grumman Mission

A Northrop Grumman Cygnus resupply spacecraft is on its way to the International Space Station with more than 8,000 pounds of science investigations and cargo after launching at 3:21 p.m. EST Saturday [Feb. 15] from NASA's Wallops Flight Facility in Virginia.

The spacecraft launched on an Antares 230+ rocket from the Virginia Mid-Atlantic Regional Spaceport's Pad 0A at Wallops and is scheduled to arrive at the space station at about 4:05 a.m. Tuesday, Feb. 18.

Expedition 62 astronaut Andrew Morgan of NASA will use the space station's robotic arm to capture Cygnus, and NASA's Jessica Meir will monitor telemetry during rendezvous, capture, and installation on the Unity module’s Earth-facing port. The spacecraft is scheduled to stay at the space station until May.

This delivery, Northrop Grumman's 13th cargo flight to the space station, the second under its Commercial Resupply Services 2 contract with NASA and designated NG-13, will support dozens of new and existing investigations.

Expedition 62 flight engineers Drew Morgan and Jessica Meir on Tuesday (Feb. 18) used the International Space Station's Canadarm2 robotic arm to grapple Northrop Grumman's NG-13 Cygnus, the S.S. Robert H. Lawrence.

The Cygnus was captured at 4:05 a.m. EST (0905 GMT).

The cargo vehicle was then attached to the Earth-facing port of the Unity module at 6:16 a.m. EST (1116 GMT) while the space station was flying over south of New Zealand.

SS Robert Lawrence departs space station

Northrop Grumman's NG-13 Cygnus spacecraft, the "S.S. Robert Lawrence," departed the International Space Station on Monday (May 11) at 12:09 p.m. EDT (1609 GMT), three months after arriving at the orbiting lab to deliver 7,500 pounds of supplies and scientific experiments to the orbiting laboratory.

With Expedition 63 commander Chris Cassidy monitoring from aboard the station, ground controllers in Houston sent commands to the Canadarm2 robotic arm to release the cargo spacecraft after it was remotely unbolted from the Earth-facing port of the Unity module and maneuvered into its release position.

Within 24 hours of its release, the Cygnus will begin its secondary mission – hosting the Spacecraft Fire Safety Experiment–IV (Saffire-IV), which provides an environment to safely study fire in microgravity. It also will deploy a series of cubesats before Northrop Grumman flight controllers in Dulles, Virginia initiate the Cygnus' deorbit to burn up in Earth's atmosphere on May 29 or May 30.
