The R Aqr jet has been extensively observed in the ultraviolet, optical, and radio regimes. We propose to re-visit this enigmatic object with HST after twelve years, in order to measure the proper motions of its inner knots with unprecedented accuracy, to derive emission lines ratios for these knots, and to investigate the width of the jet at several distances from the jet source. We will compare the results with numerical models of radiative shocks in propagating jets and of jet formation models and will determine the kinematics of the jet, the history of ejection events and basic parameters of the jet engine as e.g. the launching radius of the jet-ejecting accretion disk. All images will be obtained with the WFPC3 UVIS camera. We will use three different filters, namely [OI]6300 (F631N), Halpha6563 (F656N) and [NII]6548+6583 (F658N), in order to measure the emission line ratios in the jet knots and also the jet width along the full length of the jet, and the filter F502N for [OIII]5007 in order to follow up existing observations and measure the proper motion of knots in the jet.
