Sky Wharton again came into view and grew in size and brilliancy. An immense cargo ferry dove out of the darkness. Workmen scurried toward it, to unload it, their colored space suits reflecting the stars and the sun. Containers burst open. Rylane walls unfolded. Girders hung like webs in space, part of a new platform from which larger, faster ships would thrust deeper and deeper into the unknown.
