HS 333


American communications satellite. 8 launches, 1972.11.10 (Anik A1) to 1979.08.10 (Westar 3). The satellites, act as space repeaters capable of receiving transmissions from earth stations and retransmitting them to other earth stations in Canada.

The antenna coverage of the satellite provides the capability of serving virtually all of Canada. Each satellite had 12 RF channels each capable of transmitting a color television signal or up to 900 one-way voice channels.

Gross mass: 574 kg (1,265 lb).

Associated Launch Vehicles
  • Delta American orbital launch vehicle. The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced. More...

The Delta P upper stage was built by Douglas and used surplus Apollo lunar module engines from TRW. More...
