This model was built for my sci-fi novel "Brimstone". It carried 20 people to Mars. The pods on the sides as well as each cargo module separate on arrival at Mars and land separately - see the cover of the book for the landing. A similar ship was used to carry a whole lot more people in cryogenic pods all the way to Alpha Centauri over a period of 450 years but that book, "Travellers" is a completely different story.
