The vehicle is a cylindrical interstellar ark, peopled with a colony of humans who have departed on the first one-way voyage toward the Alpha Centauri system. The blueprint for orbital construction of such a futuristic starship was conceived by Ahad in 2004 and incorporated in the first and second novels in his First Ark series. The outer dimensions of the bullet shaped body are 12 miles (length) x 7 miles (diametric width), grossing a total mass estimated to be of the order of 1.48 x 10^14 kg (equivalent to some 10% of that of the Martian moon Deimos).
