Unrealistic. Considering how none of the planets moved from their spots in their orbits, this probably took place over the course of a day at best. The rocket travels to Mars in a couple seconds, but even at light speed, Mars would take several minutes getting to. Even with our best rockets, it still takes months to get to Mars. Even worse, there's a narrow window only once every couple years where it's optimal to start a flight to Mars. I'll let that slide solely because all of the planets are lined up in a row...at least that's what I would say if Mars was not within Earth's Roche limit. At the distance depicted, Mars would turn into a ring system around Earth. Heck, all of the planets here are in Juptier's Roche limit. All of the other planets should be collapsing into a ring system around Jupiter, or at least that's what would happen if they all weren't so close to the Sun. All of the planets in this situation would fall into the Sun unless they were traveling horizontally relative to it at a speed
