During the nine-month interplanetary journey, the 800-kg ExoMars carrier module will transport Kazachok and Rosalind the rover within a single, 2-tonne descent module, providing electrical power via a solar array.
The descent module, which does not produce any power by itself during launch and transfer, will separate from the carrier module shortly before reaching the martian atmosphere. While the descent module will deliver the rover and platform safely to the surface, the carrier module will burn up in the atmosphere.
