In February 1990, ESA began reactivation of the Giotto spacecraft, which had been dormant for the previous four years, via the omnidirectional low-gain antenna mounted atop the Giotto. By the end of April 1990, spacecraft temperatures had been reduced to levels at which the experiments could be activated; of the original complement of ten experiment modules, the magnetometer, energetic particle analyzer, and optical probe experiment were fully functional, and an additional three instruments were partly damaged but usable. A mission that targetted Comet Grigg-Skjellerup 214 million km from the earth was then put into effect.
