Defined examples — our methodology

The marked height is calibrated. Unmeasured illustration details are representative.

Luna 2

Spherical bus diameter: 90 cm; approximate.

Luna 2 used an approximately 0.9 m spherical spacecraft bus and had a mass of about 390.2 kg. Antennas and scientific booms extend beyond the calibrated body diameter.

NASA NSSDC — Luna 2

The marked spherical bus diameter is calibrated. Unmeasured illustration details are representative.
