Cygnus NG-13 (aka Robert H. Lawrence) was unberthed from the Unity Module on the International Space Station at 1300 GMT on 11 May using the space station’s robot arm. It was carrying away the HDEV experiment which had been earlier loaded (on 7 May) onto its outside by the Dextre robot for disposal. After a short wait, the arm released the spacecraft at 1409 GMT.  The Cygnus NG-13 craft went on to release a Lynk cubesat (flown to ISS on Dragon Spx 20) from its slingshot deployer (previously attached to the front of Cygnus by ISS astronauts) at 2325 GMT on 13 May. The craft operate a Lynk antenna payload attached to it.
