AI is important because we hope to some day soon build machines with human and superhuman intelligence. Once this happens, all problems that can be solved by intelligence will be solved, because we can build more and more machines that will work day and night on the problems until the answers are obtained.
Aging is an important problem to solve because eradication of aging and disease will allow humans to live forever. Once humans live forever, they will continue to learn more and more until all problems that can be solved by intelligence are solved. However, once humans live forever we will need more space to reproduce, and human life will have to expand beyond planet Earth.
Astrobiology is the study of life in the universe. The tools of astrobiology will be used by the human species to explore the universe and expand our existence beyond first our planet and then our solar system.
