An outstanding start to a science fiction series

The spacecraft reaches Mercury at the intended time and begins sending signals to determine the precise orbit of the planet. The experiment begins that evening. A command is sent to increase the speed of Mercury from the Experiment Control Centre at the moon base. Three hours later, the International Space Station, scientists at the moon station and also many other groups of scientists on Earth, register an increase in the diameter of Mercury’s orbit round the Sun by two percent. Once the experiment is over, Mercury’s orbit is slowed down to its previous level.

Soon after, a Chilean observatory observes a space object moving from outer space which could potentially collide with Earth. Precise calculations of its flight trajectory are not yet possible because it is so far away, and the orbital telescopes, even those in orbit round the gas giants, are currently being used in support of an experiment testing remote manipulation technology. In view of the low speed of the object, the time for it to reach the Earth’s orbit is estimated as hundreds of years, so a low priority is given to clarifying its trajectory. Nevertheless, the instruction is entered into the central computer for a second observation of the object a week later, to confirm the low priority status.

At the next observation session, the object is not detected. The telescope control system probes the space sectors in the region of the assumed location. The unidentified space body is eventually detected, but its actual position differs greatly from that initially assumed. Following its programmed instructions, the telescope computer corrects the calculation data and raises the priority for finally calculating the trajectory. The third observation session is appointed for 24 hours later.

The third observation session reveals an even greater calculation error. The Chilean telescope’s automatic control system has to notify the scientific personnel...
