The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

The first five Saturn IB launches for the Apollo program were made from LC-34 and LC-37, Cape Kennedy Air Force Station. The Saturn IB was used between 1973 and 1975 for three crewed Skylab flights, and one Apollo-Soyuz Test Project flight. This final production run did not have alternating black and white S-IB stage tanks, or vertical stripes ...
There was a large payload gap between the Saturn IB's 46,000-pound (21,000 kg) low Earth orbit capacity and the Saturn V's 310,000-pound (140,000 kg) capability. In the mid-1960s NASA's Marshall Space Flight Center (MSFC) initiated several studies to extend the capabilities of the Saturn family.
The pound-force is the product of one avoirdupois pound (exactly 0.45359237 kg) and the standard acceleration due to gravity, approximately 32.174049 ft/s 2 (9.80665 m/s 2). [ 5 ] [ 6 ] [ 7 ] The standard values of acceleration of the standard gravitational field ( g n ) and the international avoirdupois pound (lb) result in a pound-force equal ...
However unlike the Saturn IB the Saturn IB-CE was to be a three-stage rocket. The IB-CE used the same configuration as the Saturn IB for the first two stages however with the addition of a Centaur D/E rocket as the third stage. [1] [2] It was to be capable of delivering 22,000 kg to low Earth orbit and 5,590 kg into a translunar trajectory. [1]
Each 571 lb (259 kg) spacecraft was equipped with 11 instruments to conduct close-up studies of Jupiter and interplanetary space during transit. Following several technological advancements, Pioneer 10 was launched in 1972 from Cape Canaveral Launch Complex 36A, with the goal of exploring Jupiter, its moons, magnetic field, and radiation belts ...
The S-IB stage was the first stage of the Saturn IB launch vehicle, which was used for Earth orbital missions. [2] It was an upgraded version of the S-I stage used on the earlier Saturn I rocket and was composed of nine propellant containers, eight fins, a thrust structure assembly, eight H-1 rocket engines, and many other components.
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —
