The reason why Ingenuity has to perform several short trips over this region is that flying over non-flat terrain is a challenging task. It's risky to execute maneuvers or land when underneath the surface is filled with hills, large boulders, and dunes.
Another challenge that the team behind Ingenuity has to prepare for is the presence of hardware from Perseverance's entry, descent, and landing, which includes the parachutes and backshell. The rotorcraft will have to pass by the rover's landing site in the Jezero Crater and avoid all of the obstacles in its way. The goal is to find a large enough landing spot that doesn't have any rocks, slopes, or rover hardware.
While Ingenuity prepares for Flight 25, which will take it out of Séítah, Perseverance is making some good progress on its journey to the river delta. It is essential that Ingenuity keeps pace in order to get to the delta before the rover. Because Ingenuity only communicates with the helicopter base station located on Perseverance, it must stay near the car-sized rover to maintain a good connection. The rotorcraft must also fly ahead of Perseverance to avoid getting too close to it.
For the upcoming flight, Ingenuity will attempt to fly 704 meters (2.310 ft) to the northwest. That will break the record achieved during Flight 9 when it covered a 625-meter (2,051-ft) distance. The helicopter will also try to break its speed record as well and travel at a 12.3 mph (19.8 kph) speed.
The #MarsHelicopter completed its 24th flight on April 3. Now, Ingenuity is gearing up for Flight 25, which includes traveling 704 meters northwest – about 80 meters longer than the record-breaking Flight 9.
