China will send its youngest-ever crew of astronauts to the Tiangong space station this week, as Beijing pursues plans for a manned mission to the Moon by the end of the decade. The all-male trio will be led by Tang Hongbo, who is on his first return mission to the Tiangong space station. Accompanying him will be Tang Shengjie and Jiang Xinlin, both in their thirties and each making maiden space voyages. IMAGES AND SOUNDBITES
