Measurements, assumptions & sources +

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.

ESA — Rosetta factsheet

The marked deployed solar-array span is calibrated. Unmeasured illustration details are representative.

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.

NASA Armstrong — SR-71 Blackbird

The marked overall length is calibrated. Unmeasured illustration details are representative.

Why this measurement?

Why we use 32 m

We compare the deployed solar-array span of the Rosetta spacecraft. This is an estimate; check the notes for its rounding and uncertainty. The recorded range is 31 m to 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.
