This article is almost two years old (previously posted on blogspot), but nevertheless we believe it covers an important issue and hence we have decided to reblog this post.
In our post on meat production in outer space we briefly addressed the problem of transporting herds of animals from Earth to Space colonies. Transporting small animals like dogs and cats, will not a big deal. But larger animals like cattle or horses are much more difficult. The primary problem is with mass, launching a certain mass of payload from the surface of the Earth, cost much more mass of fuel, see Tsiolkovsky’s rocket equation. This equation tells us that it will be almost impossible to launch an elephant from Earth to Space colony. Recall that from an orbit around our blue planet to the Lagrange points of the Earth-Sun system, will only take a little amount of energy and propellant mass.
If we want to bring animals to Space colonies, we should take as little as possible…
