Lucy-mission to Jupiter Trojan asteroids wound uncover many secrets of the origin of our solar system and even the entire universe. In the next 12 years, that probe would visit 8 asteroids including 7 Trojan asteroids. The thing is that the study of the effect of sunlight on asteroids is one of the most interesting things. When the temperature of the asteroids is decreasing the speed of radioactive splitting would also decrease. And that means the frozen asteroids can hide the radioactive material from the past. And maybe by researching those Trojan asteroids and asteroids at Kuiper Belt we can find chemical combinations from the early solar system. And who knows are those asteroids also hiding the evidence of the ancient humanoid visits? Maybe asteroid missions would answer that question in the form of plutonium and neptunium remnants. If there are remains of the synthetic radioactive isotopes that thing would support the theory of ancient visitors. Before any investigation...
