Jabarkan Comet Surface Sample Return dari Program Perbatasan Baru dalam bahasa melayu

A Comet Surface Sample Return mission would acquire and return to Earth a macroscopic sample from the surface of a comet nucleus using a sampling technique that preserves organic material in the sample.

Detailed study of comets promises the possibility of understanding the physical condition and constituents of the very early solar system, including the early history of water and the biogenic elements and the compounds containing them.   Therefore, a mission that would sample and return the dust and organics from at least one if not several locations on the surface of a comet nucleus, including one in the vicinity of an active vent, is of prime interest in order to achieve the majority of the following science objectives:

Understand the structure and composition of a comet through measurement of the chemical complexity of the sampled material, grain micro texture and its cohesive forces, age and composition of ices and organic and silicate grains;

Understand the real time dynamics and evolution of a comet’s surface under the influence of sunlight by study of the diurnal conditions of its atmosphere and surface; and

Investigate a comet’s overall physical structure in order to assess its internal heterogeneity.
