Private lunar leap

摘要

Look out, moon. A private company has sent its lunar-lander steering system on a test flight, taking one small step towards a planned moon mission next year. Astrobotic of Pittsburgh, Pennsylvania, is one of 18 teams competing for the Google Lunar X Prize, which offers $20 million to the first private group that lands a spacecraft on the moon, drives it 500 metres, and sends two videos by the end of 2015.
