NG-15 SlingShot Deployment



International Space Station – June 30, 2021

NG-15 was our 6th successful mission for L2 Solutions, Inc. - Space System Division. On June 29, 2021 Cygnus unberthed from the International Space Station (ISS) with Slingshot mounted on the PCBM of the Cygnus Vehicle. Upon departure from the ISS, Cygnus utilizes the remaining fuel to ascend to an altitude of 450km-500km. Once the specified altitude is reached, Slingshot received the signal to deploy three 6U Cubesats.


Our unique launch system allows for our customer payloads to be launched to the ISS with a soft bag ride to space. Once on station, our Astronauts mount Slingshot to the PCBM of Cygnus as well as our customer’s cubesats.


L2 Solutions, Inc. would like to thank our partners NASA, Northrop Grumman, Spaceflight Services, US Army, and other undisclosed USG customers. We are proud of our hardworking team to make this mission a success.


About CRS Mission NG-15:

The CRS mission NG-15 was named S.S Katherine Johnson in honor of Black History Month. Katherine Johnson was a pivotal figure in the first thoughts of flying to space. In her 35 yr career at NASA as an aerospace technologist she accomplished many extraordinary things. She calculated the trajectory of the first American in space, Alan Shepherd. Her calculations identified the launch window in Alan Shepherds 1961 Mercury Mission. Johnson’s calculations were also crucial in case of electronic failures, by creating backup navigation charts for astronauts. Among her other accomplishments, she calculated the trajectories of Apollo 11 and Apollo 13 Moon Missions. Northrop Grumman couldn’t have picked a better name to represent this mission.
