It was quite by chance (if there is such a thing) that Sir Lawrence became personally involved in the space business. He had, of course, extensive maritime and aeronautical interests, but these were handled by his five sons and their associates. Sir Lawrence's real love was communications – newspapers (those few that were left), books, magazines (paper and electronic) and, above all, the global television networks.

Then he had bought the magnificent old Peninsular Hotel, which to a poor Chinese boy had once seemed the very symbol of wealth and power, and turned it into his residence and main office. He surrounded it by a beautiful park, by the simple expedient of pushing the huge shopping centres underground (his newly formed Laser Excavation Corporation made a fortune in the process, and set a precedent for many other cities).

One day, as he was admiring the unparalleled skyline of the city across the harbour, he decided that a further improvement was necessary. The view from the lower floors of the Peninsular had been blocked for decades by a large building looking like a squashed golfball. This, Sir Lawrence decided, would have to go.

The Director of the Hong Kong Planetarium – widely considered to be among the five best in the world – had other ideas, and very soon Sir Lawrence was delighted to discover someone he could not buy at any price. The two men became firm friends; but when Dr Hessenstein arranged a special presentation for Sir Lawrence's sixtieth birthday, he did not know that he would help to change the history of the Solar System.

5 – Out of the Ice

More than a hundred years after Zeiss had built the first prototype in Jena in 1924, there were still a few optical planetarium projectors in use, looming dramatically over their audiences. But Hong Kong had retired its third-generation instrument decades ago, in favour of the far more versatile electronic system. The whole of the great dome was, essentially, a giant television screen, made up of thousands of separate panels, on which any conceivable image could be displayed.
