Square shower tray

Length: 90 cm; example.

0.9 × 0.9 m example footprint. Defined example; real examples vary.

Defined examples — our methodology

The marked length 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.
