SPACE MISSION

摘要

Back in July, the 'red planet' Mars came the closest it has been to Earth since 2003 and, for many of us, was clearly visible as a glowing red dot in the night sky. Of course, the plan is that humanity will eventually get even more 'up close and personal' with Mars, with the US space agency NASA hoping to send a manned mission to the planet in the 2030s. This, in turn, has led to intense activity around what sort of sustainable habitats could be created for astronauts on the planet and how they would survive the long journey to it (or indeed any other) planets.
