Spatially resolved profiles of the Halpha and [NII] lines have been obtainedat unprecendented signal--to--noise ratios over the outflowing lobes of thehigh--excitation, poly--polar planetary nebula NGC~6302. A deep image in thelight of [NII]6584 A was also obtained of the extremities of the prominentnorth--western lobe. The Manchester Echelle spectrometer combined with the2.1--m San Pedro Martir telescope (Mexico) was used for these observations.  Firstly, an accurate value of the systemic heliocentric radial velocity ofVsys = -29.8 +/- 1 km/s has been established. Also, from `velocity ellipses'across its diameter from previous observations the parallel--sidednorth--western lobe is shown to have a circular section with a tilt of its axisto the plane of the sky of 12.8 deg. With this starting point the pv arrays ofprofiles have been very closely simulated, using the SHAPE code, withHubble-type outflows. The faint extremities of the north--western outflow areshown to be expanding at 600 km/s. The prominent lobes of NGC~6302 have thenbeen generated in an eruptive event with a dynamical age of 1900 y for theexpansion proper-motion distance of 1.04 +/- 0.16 kpc as measured here bycomparing a 1956 image with that taken in 2002.  Kinematical evidence of a high--speed `skirt' around the nebular core,expanding nearly orthogonally to the lobes, is also presented as are theunusual motions at the western extremities of the NW lobe.Comment: 32 pages, 15 figures, accepted by Astronomical Journa
