The 10-day mission aims to send the crew past the moon and around its far side before returning directly to Earth, testing life-support and other critical systems, and is also intended to pave the way for future lunar landings. Originally scheduled for February, the mission was postponed when a helium leak was discovered, and NASA abandoned that launch attempt.
