Because they're in different orbits. Earth is closer to the sun than Mars, while Jupiter is about 5 times as distant (likely more in this photograph). Earth and Jupiter in this photograph are likely in perpendicular positions relative to the sun. Mars is obviously near-parallel to Earth's terminator line, so to have Jupiter in the same picture it has to run on a nearly straight line through Earth from Mars, given this distance is likely ~7AU or more, Jupiter is on a whole different angle from the sun. Crudely drawn I believe it should be something(!) like this: M E (S) J
