During the year leading up to Stardust-NExT's encounter with comet Tempel 1, a total of sixty observers using twenty-five different telescopes, in ten different countries assisted the mission in better understanding the rotation state and spin period of the comet. In addition, the observation team was able to give mission scientists a better understanding of the overall shape of the comet as well as its final position at the time of encounter which was critical to the mission. Observers learned that the comets activity began ~ 600 days before perihelion and lasted until 800 days after as well as the fact it stayed active for 70% of its 5.5 year orbit. This fact had been previous unknown based on previous data and provided scientist with a useful and new prospective.
