While the concept of the block universe has a most respectable scientific provenance, many physicists nevertheless do not accept that future events are just as embedded in spacetime as are those of the present and the past. This paper proposes an experiment to demonstrate the block universe using interplanetary distances and high relative speeds such as those accessible through the NASA Mars Reconnaissance Orbiter. The proposed experiment hinges on signals exchanged between Earth and the Orbiter which reveal a time interval of some tens of milliseconds in the future of the Earth which is already in the past of the Orbiter. Since this experiment can be performed at any time, and since the magnitude of the time interval can in principle be increased in proportion to the distances and speeds over which it is performed, an observer can always be found for whom the past is in the future of another observer. The only explanation that fits these observations is a block universe in which all events in the past, present and future of any observer are equally enfolded into spacetime.
