Precursors

Scientists are interested in Bennu because they believe it contains material from the early solar system and may contain the molecular precursors to life and Earth’s oceans.

In the field of astronomy, there are researchers who postulate that a long-lived spacefaring civilization would be post-biological. Perhaps, in such a scenario, the biological precursors would be relegated to live just on the home world. For us humans, we question whether our bodies would be too fragile for deep space, and maybe we would leave deep space for our machine children with intellect.

Researchers hope the findings will lead to ways to prevent allergies and wheezing, which are both precursors to asthma.
