How will the probe get most of it traveling energy?

Answer 1

the energy for the flight will come from using the gravitation pull of earth and venus

Answer 2

The probe can gather most of its traveling energy from its initial launch using a rocket propulsion system. Once in space, the probe can utilize solar panels to convert sunlight into electricity to power its onboard systems and instruments. Additionally, some probes use radioisotope thermoelectric generators (RTGs) that convert the heat from the radioactive decay of isotopes into electricity for long-term power.
