America’ s space agency has a legendary love of paperwork. Consequently, NASA has published over 6,000 pages about the contracts for its Crew Exploration Vehicle (CEV) , the craft that will put people into orbit around Earth, allowing them to carry out tasks such as visiting the international space station after the shuttle fleet is retired in 2010. But the CEV is also central to the agency’ s new vision of putting people back on the moon.
Frank Sietzen, a journalist and coauthor of "New Moon Rising" , a chronicle of the development of the new NASA vision, has spent the better part of the past six months leafing through these contracts in order to divine the agency’ s plans. He says that because the CEV must be compatible with other components of the vision, the contracts give de tails of how NASA is planning to explore the moon and Mars.
According to Mr Sietzen, the new moonships will have three components
A. separate.
B. worship.
C. forecast.
D. spoil.
