A little perspective
Lockheed SR-71 Blackbird vs Rosetta spacecraft: length comparison
The overall length of the Lockheed SR-71 Blackbird is about 1.02 times the deployed solar-array span of the Rosetta spacecraft.
The Lockheed SR-71 Blackbird is a long-range, high-altitude reconnaissance aircraft developed for the United States Air Force during the Cold War.
Rosetta was an ESA spacecraft launched to study comet 67P/Churyumov–Gerasimenko, carrying the Philae lander and powered by solar arrays.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

Lockheed SR-71 Blackbird
Overall length: 32.7 m; specified; range 32.6 m–32.8 m.
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.

The marked overall length is calibrated. Unmeasured illustration details are representative.
Rosetta spacecraft
Deployed solar-array span: 32 m; approximate; range 31 m–33 m.
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.
