The chemical composition of chondrules can help scientists understand the structure and composition of the nebula of gas and dust from which the planets and asteroids formed.

The pieces of the asteroid Ryugu could answer stubborn questions about the origins of our solar system, including how chondrules were made.

"The mission will proceed over several phases with the introduction of different types of particles into the ETC, beginning with large solid spherical particles, and finishing with aggregates of micron-sized dust and chondrules."

In the other camp, which proposes chondrule formation was post-planetesimal, one of the more prominent models is called impact jetting.

To form, chondrules must be heated and then cooled rapidly, a scenario that is difficult to explain.
