So instead, small objects will simply collide with planets. Universe Sandbox ² doesn’t yet simulate the forces associated with atmospheric entry, like atmospheric drag and aerodynamic heating. This is what happened to Cassini as it entered Saturn’s atmosphere. If it’s small enough, then it should instead disintegrate in the planet’s atmosphere. But just because an object is on a collision course with a planet, that doesn’t mean it should actually collide with that planet in every scenario. We love collisions in Universe Sandbox ².
In the end, however, we decided it was still an informative and interesting visualization of an event that is very important to science and the world.īut instead of brushing these limitations under the rug, we’d like to take a closer look at them. We had initially been wary of including a simulation of this event, as there are several limitations in Universe Sandbox ² that reduce the realism of this particular simulation.

To commemorate this event, we released Ciao, Cassini | Update 20.2 which featured a simulation of Cassini’s final hours and collision with Saturn. After its 20-year-long mission in space, it was running low on fuel, so NASA directed it toward Saturn in order to eliminate the risk of it contaminating the moons. On September 15, 2017, Cassini sent its final image back to Earth before disintegrating in Saturn’s atmosphere. It’s been two weeks now since we said goodbye to the Cassini spacecraft.
