There are nine Rutherford engines on the first stage and one vacuum-optimized version on the second stage. [26] [27] [28] The first stage engines deliver 162 kN (36,000 lb f) of thrust and the second stage delivers 22 kN (4,900 lb f) of thrust. Almost all of the engines' parts are 3D printed to save time and money in the manufacturing process ...
Northrop offered a "minimal" 6.1-meter (20 feet) by 3-meter (9.8 feet) design based on the Cygnus spacecraft, as well as a larger 7-meter (22.9 feet) by 4.4-meter (14.4 feet) design also based on the Cygnus, [7] [12] to the outside of which radial docking ports, body-mounted radiators (BMRs), batteries and communications antennae will be added ...
