Northrop Grumman has launched its Cygnus cargo ship to the International Space Station along with 7.5K pounds of research and scientific payload as part of the NG-13 mission for NASA.
NASA said Sunday the Antares 230+ launch vehicle lifted off from the agency's Wallops Flight Facility in Virginia at 3:21 p.m. EST on Saturday and was slated to arrive at the station at 4:05 a.m. on Tuesday.
Cygnus carried five experiments including a miniature electron microscope, bacteriophage technology, fire production research and bone-loss examination studies.
The Cygnus spacecraft for the NG-12 mission that launched in November departed from the ISS on Jan. 31.
NG-13 serves as Northrop's 13th Cygnus flight to the station and second under NASA's Commercial Resupply Services 2 contract.
