space flight, 2004
For space flight, 2004 was a year of strong contrasts. Human and robotic space activities set new marks with a lineup of unique accomplishments, preparing the stage for new developments that will contribute greatly to human exploration beyond the Earth. At the same time, 2004 saw a decline in the utilization of space, as the number of launches to orbit plus the number of satellites reached the lowest levels since 1961.
