A little perspective

The launch mass of Gaia spacecraft is about 1.02 times the mass of 2 tonnes.

Measurements, assumptions & sources +

2 tonnes

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Gaia spacecraft

ESA’s Gaia observatory was approximately 3.5 m high and had a launch mass near 2,030 kg. Its deployed circular sunshield defines a much larger transverse span.

ESA — Gaia factsheet

The marked launch mass is calibrated. Unmeasured illustration details are representative.

Comparing
Mass ↔ Launch mass
Relative size
Gaia spacecraft is larger on this measurement by a factor of about 1.02. Gaia spacecraft's selected measurement is approximately 1.5% greater than 2 tonnes's.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Gaia spacecraft is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
