"Picard: a satellite to measure the Sun’s diameter” (parts 1, 2 and 3)
By François Buisson, CNES Picard project leader, and Gérard Thuillier, Picard mission science lead, INSU/CNRS/LATMOS (in French)
Unbelievable though it may seem, in 2010 we still didn’t know the Sun’s exact diameter. Since Jean Picard first measured it precisely in the 17th century, when the Sun had very few sunspots, observations during solar eclipses and with ground and space telescopes had not been able to resolve the enigma that still defied specialists studying our star: Are the Sun’s diameter and activity related?
In particular, as questions are being raised about the value of data from climate prediction models, what causes the Sun’s variability and what effects does it have on Earth’s climate?
With big questions like these, the Picard microsatellite developed by CNES had big ambitions. Like Demeter and Parasol before it, Picard acquired new measurements for scientists, from the ground and from space.
