I have already joined to Using English and this is my first post. These days I'm reading 'The Martian' by Andy Weir and I have a question about meaning a sentence.
Every step of the way would have had beeping alarms, alerts, and warnings. But it was the high-oxygen warning that woke me. The sheer volume of training for a space mission is astounding. I’d spent a week back on Earth practicing emergency space suit drills. I knew what to do.
Can anyone explain the meaning of "a week back on Earth" in this paragraph? maybe it is very easy but I couldn't understand
