A little perspective

The launch mass of Skylab is about 1.54 times the mass of 50 tonnes.

Measurements, assumptions & sources +

50 tonnes

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Skylab

Skylab was approximately 36.1 m long in orbit and had a launch mass of 77,088 kg. Deployed solar arrays extend across its width but do not define the measured longitudinal span.

NASA — The launch of Skylab

The marked launch mass is calibrated. Unmeasured illustration details are representative.

Mass ↔ Launch mass
Relative size
Skylab is larger on this measurement by a factor of about 1.54. Skylab's selected measurement is approximately 54.2% greater than 50 tonnes's.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
