List all Mars probes manned by NASA, including failed missions.
For missions that included multiple probes, enter all of them separately. For example, if the quiz were about moon missions, "Apollo" would not be accepted, but "Apollo 11" and "Apollo 13" would be.
"Launched on above mission" in the Launch Date column means that the probe was launched as part of the mission listed above it. For example, the Huygens probe would be listed below Cassini as "launched on above mission."
Does not include Mars Express, because while NASA is participating in this mission it is primarily managed by the ESA.
