NG-15 Cygnus takes aim on the ISS after successful launch

Northrop Grumman’s NG-15 Cygnus cargo spacecraft has been sent on its way to the International Space Station after soaring into orbit atop an Antares 230+ rocket.

The autonomous NG-15 Cygnus spacecraft, dubbed SS Katherine Johnson, is carrying some 3,700 kilograms of crew supplies and experiments for the space station’s seven-person Expedition 64 crew.

After nearly three months at the International Space Station, the NG-12 Cygnus spacecraft was unberthed, released and commanded to depart the vicinity of the outpost to begin its post-ISS mission.

The spacecraft, named SS Alan Bean, was detached from the Earth-facing port of the Unity module during the morning of Jan. 31, 2020. Several hours later, at about 14:35 UTC, Cygnus was released and slowly drifted away.

Northrop Grumman’s NG-11 Cygnus departed the International Space Station following its 3.5-month stay aboard the orbiting laboratory, beginning a multi-month free-flying secondary mission. Using the robotic Canadarm2, the spacecraft was unberthed Aug 6, 2019, from the Earth-facing port of the Unity module and positioned about 10 meters below the Destiny laboratory module and released to slowly move away from the ISS.

NG-10 Cygnus ends post-ISS mission after deploying satellites

Having launched Nov. 17, 2018, and spent 81 days attached to the International Space Station, the NG-10 Cygnus, named SS John Glenn by Northrop Grumman, was unberthed Feb. 8 to perform a two-week stand-alone mission. That post-ISS flight came to an end at about 09:00 UTC Feb. 25, 2019, when the spacecraft’s engine performed a deorbit burn to lower its orbit enough for Earth’s atmosphere to drag it down, safely burning it up of the Pacific Ocean.
