Answer:
The limited autonomy of the robotic rovers on Mars posed a big problem.
Explanation:
Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.
I'd like to say it's food. However I'm not sure
<span>I think you meant chromosome aberration. In that case, it is when a chromosome is “abnormal,” such as having a “wrong” structure or missing a chromosome. There are four types of mutations: deletion, duplication, inversion, and translocation. The fifth is deficiency, when a chromosome is lost during the development stage of a fetus. I’m not an expert on this, but I hope it helped</span>
