Eliza wonders, floating in the corridors of Gateway, watching the RLVs rise into low Earth orbit, the continents shifting past, the clouds swirling, endlessly, this whole strange giant spaceship planet as it travels at 1200 kilometres an hour around the sun, while at the same time Earth, Mars, Venus, Sun and all travel at nearly 800,000 kilometres per hour around the centre of the galaxy, while at the same time this speed machine, Earth and sun and the galaxy itself move at 1000 kilometres per second towards the Great Attractor, that most mysterious of gravitational enigmas, this anomaly of mass that pulls to it the Milky Way as if it were a pebble: all this and we think we're still, and it makes Eliza dizzy just to think about it.
