NASA's new moon rocket sprang another dangerous fuel leak on Sept. 2, forcing launch controllers to call off their second attempt this week to send a crew capsule into lunar orbit with test dummies. The inaugural flight is now off for weeks, if not months.

A new Chinese carrier rocket made its first flight on Tuesday under a long-term plan to develop reusable launch vehicles aimed at reducing mission costs and speed up launch schedules for commercial clients.

The medium-lift Long March 8 Y-1 blasted off at 12:37 p.m. (0437 GMT) from the southern Chinese island of Hainan carrying five satellites, state media reported.
