Measurements, assumptions & sources +
Rosetta spacecraft
ESA’s Rosetta spacecraft spanned approximately 32 m across its two deployed solar-array wings and had a launch mass near 3,000 kg. The Philae lander is included in launch mass, not shown as a separate body.
The marked deployed solar-array span is calibrated. Unmeasured illustration details are representative.
Lockheed SR-71 Blackbird
A rounded SR-71 reference: 32.7 m long, 16.9 m span, about 78 t maximum takeoff mass and roughly 980 m/s at high-speed cruise. Mission profile changes speed and mass.

Why this measurement?
Why we use 32 m
For comparison, this page uses deployed solar-array span. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 31 m to 33 m.
