Armchair Excursions

One thing is for sure, we can’t sustain the cheap availability of air travel for ever. Economists (and science fiction authors) have described futures where physical long distance travel will be either very rare and expensive, or done the slow way (by land or sea). Seems that NASA has clicked to this idea as well, with the launch of ‘Virtual Field Trip’, an immersive multimedia experience designed for students (but available to all) who want to explore remote parts of Australia in the company of scientists.
