Cryogenic Cometary Sample Return

Comets likely formed in the outer regions of the protosolar nebula where they incorporated and preserved primitive presolar materials, volatiles resident in the outer disk, and more refractory materials from throughout the disk.

Interstellar comets offer direct samples of volatiles from distant protoplanetary disks. 2I/Borisov is the first notably active interstellar comet discovered in our solar system[1].

The isotopic ratio of nitrogen measured in primitive Solar System bodies shows a broad range of values, the origin of which remains unknown.

While the Rosetta spacecraft orbits the 67P/Churyumov-Gerasimenko comet, the Philae lander, deployed from Rosetta on November 2014, has gathered data on the surface of the comet that indicate the potential existence of prebiotic organics during the early solar system.

In another step forward in the search for habitable planets, a team of researchers based out of the US and Chile announced that they have located a large swarm of comets and gas moving in a cloud around a nearby star.
