Interactive 2D deep-space radio link: drag the spacecraft out through the LEO, Moon, Mars, Jupiter and Voyager rings and watch a live link-budget waterfall (transmit power, dish gains, free-space path loss, atmosphere, ionosphere) against the required signal level, with ionospheric cutoff and Earth occultation.
