Unsuccessful attempts to travel to the other planets were made during the years 2021-2027. The Pioneer II, bound for Mars, the Adventurer, bound for Mars, and the Enterprise, bound for Venus, all disappeared without a trace. In September, 2028, the Space King returned to Earth after completing a voyage to Mars. The ship landed safely, but the excited celebration that greeted it was short-lived when it was discovered that the entire crew was afflicted with a neurological disease that your Earth scientists labeled 'space sickness'. This disease posed a new obstacle to interplanetary travel. It attacked indiscriminately and it proved fatal in almost every case. Research and experimentation on the cause and cure of 'space sickness' was carried on continuously from the time the Space King returned with its dying crew until the disease was conquered in 2041. During these years, the experimental ships Enterprise II, Razorback, and Space King II were utilized as laboratories in orbital flights. In April, 2041, the space liner Morning Star was completed, incorporating technological improvements designed to prevent the occurrence of 'space sickness'. The Morning Star left the Lunar station on July 17, 2042. Its destination was Venus. In government circles on Venus, it was felt that no further delay could be permitted in establishing contact with the people of Earth. They were already too close to space flight maturity to forego any opportunity for formulating an understanding. Therefore, The Morning Star, whose flight had been observed constantly, was allowed to pass through our ionic barrier and land unharmed on our planet. Emissaries of our Lora Dannun (nearest translation: Supreme Council) were on hand to greet the Earthmen when they left their ship. As a precautionary measure, two atomic scorchers were trained on the ship, but our officials approached the debarking Earthmen without side arms and in a friendly manner. The Earthmen, understandably apprehensive, came forward with their hand weapons drawn. Although we on Venus were already familiar with your International English language, our welcoming committee did not think it wise to further startle the men from Earth by greeting them in their own tongue. Therefore, our friendly intentions were made known by elaborate and unmistakable gestures. The aliens from Earth, nevertheless, were startled enough by our appearance. They stared wide-eyed at what appeared to be four child-like specimens of human beings.
