Orbital Sciences CYGNUS CRS Flight 13, is the 14 flight of the Orbital ATK unmanned resupply spacecraft Cygnus and its 13 flight to the International Space Station under the Commercial Resupply Services contract with NASA. Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation System (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital′s industrial partner Thales Alenia Space.

On Feb 15, 2020 Cygnus mission NG-13, the S.S. Robert Lawrence, was launched on an Antares from Wallops Island on a mission to deliver cargo to the ISS.
Cygnus NG-13, the S.S. Robert Lawrence, was grappled by Canadarm-2 at 0905 UTC Feb 18 and berthed at Unity nadir at 1116 UTC.
NG-13′s pressurized cargo of 3466 kg includes;
- ColKa, a Ka-band antenna package to be EVA-installed on Columbus. (ESA, built by MDA-UK; 120 kg)
- RED-EYE 2, a DARPA satellite (100kg class, Kaber deployer)
- Nanoracks NRCSD-18 deployment with 2 known cubesats:
  DeMi, a 6U cubesat with a DARPA deployable mirror experiment, led by Aurora Flight Sciences (10 kg class)
  TechEdSat-10, a 1x6U cubesat (0.6 x 0.1 x 0.1m) with a controllable aerobrake for targeted reentry (Ames/San Jose State, 10 kg class)
NG-13′s external cargo of 167 kg is an NRCSD-E deployer carrying unknown cubesats.
The S.S. Robert E. Lawrence, the Cygnus NG-13 cargo ship, was unberthed from the Unity module at about 1300 UTC May 11, 2020 by the Canadarm-2, which released it into orbit at 1609 UTC. It then raised its orbit to 475 x 483 km, where it remains as of May 24.
Cygnus NG-13 was deorbited over the Pacific on May 29, 2020 with reentry at 1930 UTC.
