In our experiment, elliptically polarized, 750~nm, 4.5~fs laser pulses were focused to an intensity of $9\\times10^{14}\\mathrm{W/cm}^2$ onto H$_2$. Using coincidence imaging, we directly observe the nuclear wavepacket evolving on the \\ssg{} state of H$_2^+$ during its first roundtrip with attosecond temporal and picometer spatial resolution.
