In the 1970s, a British initiative named Project Daedalus designed a spacecraft meant to journey to another star. America's project Icarus takes up the task anew. "One of the most exciting parts of Project Icarus which is on everyone's mind with an interest in the project, is what will the spacecraft look like? Will it be very similar to the Daedalus design or radically different? The core section of the Daedalus vehicle was the use of a slender structural spine, from which all the other components could be attached. The use of this spine was possible due to the low vehicle acceleration levels and assembly in space."
