Crewless Mission to Hypothetical Planet Nine and My Role as Programmer

I am sending spacecraft to the hypothetical Planet 9 introduced by Caltech scientists Brown and Batygin after noticing that eccentric, distant Kuiper Belt Objects may be perturbed by an unknown planet. Scientists estimate the planet’s mass, semimajor axis, and eccentricity; soon, they will measure the KBOs more accurately to get an approximate location. The new Vera Rubin Observatory, which photographs almost half the sky, could detect the slowly moving Planet 9 and distinguish it from stars, galaxies, or fast moving Solar System objects. After locating the planet, we will send a crewless fly-by mission. Even with gravity assist, the trip will take decades. Since sunlight doesn’t reach Planet 9, the spacecraft will use radio-isotope power for course corrections and to power computers, cameras, spectrographs, and communication. Spectral lines will be used to identify molecules on the surface or atmosphere. My personal trait for this mission is ability to program. I am learning Python for projects like this. I will program the spacecraft to take instructions, navigate, make measurements, and analyze and compress data to transmit to Earth. My programs will need to be tested; I will write special programs to simulate real situations that may happen during the mission.
