What is the significance of the salts found in the Bennu samples, and what does their presence suggest about the asteroid's history?

The Bennu samples, the first from an asteroid's surface obtained by NASA and the only ones collected from a planetary body in nearly 50 years, reveal thousands of organic molecules. These include 14 proteinogenic amino acids found in Earth life, 19 non-proteinogenic amino acids, and all five biological nucleobases. The asteroid's richness in nitrogen-containing compounds suggests formation in cold, outer solar system regions.
