The cable was connected to a cylindrical weight inside a tube. The weight rested on a lever controlled by a pneumatic solenoid valve. When the valve was actuated from the Launch Control Center (LCC), the pneumatic pressure of 600 psi (4,100 kPa) GN2 (nitrogen gas) rotated the lever down allowing the weight to drop down the tube.
The reduction in parts costs is aided by using selective laser melting in the production of some metallic parts. [ 13 ] [ 18 ] The resulting F-1B engine is intended to produce 1,800,000 lbf (8.0 MN) of thrust at sea level, a 15% increase over the approximate 1,550,000 lbf (6.9 MN) of thrust that the mature Apollo 15 F-1 engines produced.
During crewed Apollo missions, the vehicle coasted in Earth orbit for 2-4 passes as the crew performed checks of systems status and other tasks, and as ground stations tracked the vehicle. During the hour and a half after launch, tracking stations around the world had refined estimates of the vehicle's position and velocity, collectively known ...

On the Apollo 6 uncrewed Block I flight, the SM was painted white to match the command module's appearance. On Apollo 1, Apollo 4, and all the Block II spacecraft, the SM walls were left unpainted except for the EPS and ECS radiators, which were white. The EPS and ECS radiators were redesigned for Block II.
New research has found that about 2.2 million new diagnoses of type 2 diabetes and 1.2 million new cases of cardiovascular disease may be attributed to sugar-sweetened sodas and juices each year.
