Cassini spacecraft
The Cassini spacecraft was a NASA probe launched to study Saturn and its moons, carrying scientific instruments and the Huygens lander.
Also known as: Cassini-Huygens orbiter, Cassini orbiter
How big is it?
6.8 m tall
Overall spacecraft height · specified
Typical recorded range: 6.7 m to 6.9 m.

A little perspective
About the same scale as Apollo lunar module.
Apollo lunar module: The Apollo lunar module was a two-stage spacecraft used by NASA to land astronauts on the Moon and return them to lunar orbit during the Apollo missions.
Measurements, assumptions & sources +
Cassini spacecraft
Cassini stood about 6.8 m high and had a 5,712 kg launch mass including the Huygens probe and propellant. Long instrument booms extend beyond the calibrated body-height span.
The marked overall spacecraft height is calibrated. Unmeasured illustration details are representative.
Apollo lunar module
The Apollo lunar module was about 7.04 m high. The 15,103 kg value is the Apollo 11 lunar module at separation, including descent and ascent stages; mission configurations differed.

Why this measurement?
Why we use 6.8 m
For comparison, this page uses overall spacecraft height. The record labels this value specified, so the stated convention rather than an inferred average controls the comparison. The recorded range is 6.7 m to 6.9 m.
Cassini stood about 6.8 m high and had a 5,712 kg launch mass including the Huygens probe and propellant. Long instrument booms extend beyond the calibrated body-height span.
The marked vertical span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
