Description
Gaia is in orbit, well into commissioning. I will will give an overview of Gaia's status, and potential to quantify mass distributions on interesting scales. i shall also briefly summarise recent work on chemical evolution in ultrafaint dSph galaxies, and the implications for feedback as a mechanism to perturb - or not - dark matter cusps and cores.
