NASA astronauts have only managed to live continuously on the International Space Station (ISS) for a year and Biosphere 2 on Earth failed at two years of uninterrupted human habitation. Both cases required extracting the sickened people from the toxic environments. At this point it is ludicrous to talk about a permanent manned base on Mars.

What is it that Australians celebrate on 26 January? Significantly, many of them are not quite sure what event they are commemorating. Their state of mind fascinated Egon Kisch, an inquisitive Czech who was in Sydney at the end of January 1935. Kisch has a place in our history as the victim, or hero, of a ludicrous chapter in the history of our immigration laws. He had been invited to Melbourne for a Congress against War and Fascism, and was forbidden to land by order of the attorney-general, R. G. Menzies. He had jumped overboard, broken his leg, gone to hospital, failed a dictation test in Gaelic and been sentenced to imprisonment and deportation. When the High Court declared Gaelic not a language, Kisch was free to hobble on our soil...

Now, I can understand why the appearance of a man struggling violently, as it would seem, with an airy nothing, and calling for assistance against a vision, should have appeared ludicrous. Then, so great was my rage against the mocking crowd that had I the power I would have stricken them dead where they stood.

And then, on the final day, it was time for the faux Underground Railroad. This is the part that no one believes. "No adult would ever do that," they say. "You can't be remembering that right." I am, in fact, remembering it perfectly. The counselors "shackled" us together with jump ropes so we were "like slave families" and then released us into the woods. We were given a map with a route to "freedom" in "the North", which must have been only three or four hundred feet but felt like much more. Then a counselor on horseback followed ten minutes later, acting as a bounty hunter. Hearing hooves, I crouched being a rock with Jason Baujelais and Sari Brooker, begging them to be quiet so we weren't caught and "whipped." I was too young, self-involved, and dissociated to wonder what kind of impact this had on my black classmates. All I knew was that I was miserable. We heard the sound of hooves growing closer and Max Kitnick's light asthma wheezes from beind an oak tree. "Shut up," Jason hissed, and I knew we were cooked. When the counselor appeared, Sari started to cry.
