Launch! The fastest spacecraft ever launched
began the first full day of its 3-billion mile journey to Pluto, where it will
study the last unexplored planet and the mysterious icy area that surrounds it.
The New Horizons spacecraft blasted off aboard an Atlas V rocket Thursday afternoon in a spectacular start to the $700 million mission. Despite the speed — it can reach 36,000 mph — it will take 9 1/2 years to reach Pluto and the frozen, sunless reaches of the solar system.
The 1,054-pound spacecraft is loaded with seven instruments that will photograph the surfaces of Pluto and its large moon, Charon, and analyze Pluto's atmosphere.
New Horizons relies on Hi-Shear's SN9421-7 (7/ 8") Separation Nut actuated by a PC154 Booster Cartridge to release the Atlas V PLF Umbilical Boom (a Pluto Mission unique application). Despite two days of delays due to weather and a power outage at the spacecraft's control center in Maryland, the launch occurred without incident.
Hi-Shear is proud of its history of supplying mission critical explosive and
mechanical components to NASA.
