| Spacecraft & payload |
The Gaia information sheets are A4-page summaries of various aspects of the Gaia project. They are compiled by members of the Gaia Science Team, the Gaia Scientific Community, and other individuals contributing to the Gaia mission.
Every effort is made to keep these information sheets up-to-date but due to the evolving design of the spacecraft and payload (at this phase of the mission) there will be periods when some information contained in these sheets has been superceded. If you require the most recent value of any parameter you should consult the Gaia Parameter Data Base.
