Northrop Grumman to launch Antares Cygnus Cargo to the ISS #NG15​

Streamed live Feb 20, 2021

As part of the Commercial Resupply Services (CRS), Cygnus will carry nearly 3,600 kg (~ 8,000 lb) of science experiments, crew supplies and hardware to the ISS. The crew of Expedition 64 will catch, and Mission Control will berth the Cygnus spacecraft on February 22 to the bottom of the Unity module. NG-15 will mark Northrop Gumman’s 15th ISS resupply mission.

The Antares 230+ is a two stage expendable rocket that can carry up to 8,000 kg (~17,600 lb) into Low Earth Orbit (LEO). With dimensions of 42.5 m (~139 ft) and 3.9 m (~13 ft), the Antares 230+ is about the same height and diameter as the first stage of SpaceX’ Falcon 9. With two Russian RD-181 engines on the first stage, the rocket lifts off the pad with 3,844 kN (~864,000 lbf). Its first stage is propelled by Rocket Propellant 1 (RP-1) and liquid oxygen (LOX). The second stage on the other hand is a Castor-30XL solid rocket motor. Fueled by hydroxyl-terminated polybutadiene (HTPB) and aluminum, it produces 474 kN (~107,000 lbf) of thrust.
