Gaia aims at producing micro-arcsecond-precision astrometry of a vast number of stars and other celestial sources. This involves the task of reconstructing and understanding the rotational motions of the free-floating Gaia spacecraft to micro-arcsecond-precision. The Gaia "First Look" group of ARI is in charge of the root steps of this task, plus a daily in-depth verification of the instrument health on board and the scientific quality of the data coming to the ground. Sounds boring? But it isn't! I will describe and explain a few of the adventures of Gaia's "First Look Scientists" at ARI, including a very recent one.
