The MarcoPolo-M5 mission will study the D-type Near Earth Asteroid 1993 HA and return a sample for detailed laboratory investigation. D-types are the most abundant asteroids beyond the outer edge of the main belt, contain abundant organics and volatiles, and are widely believed to be the most primitive “rocky” material present in the solar system. They appear to have been formed in the outer regions of the protoplanetary disk, and have strong spectral similarities to comets which must have formed in similar regions of the early solar system.
The ESA Rosetta mission has provided spectacular data about a comet, but detailed information about the complex, ultra-fine grained material that forms the comet is not available because of the limitations of space-borne instruments. Meteorites sample many small bodies but examples of possible D-type material are almost completely absent in the collection. D-type asteroids therefore provide a unique opportunity to investigate the very birth of our solar system, completing many of the missing pieces of our knowledge about the birth of our solar system, the origin of Life and evolution of the planets.
From the orbital observations, in situ lander measurements and detailed laboratory analyses of the returned samples the mission seeks to answer the following fundamental questions:
Within each top level question there are a series of more specific goals.
Answers to these fundamental questions require measurements with exceptional levels of precision and sensitivity that can only be achieved by instruemnts back on Earth.
On-board instruments and a small lander will characterise 1993 HA to select the best sampling site and provide geological context to the collected samples.
