Pioneer 5

Pioneer 5 (also known as Pioneer P-2, and Thor Able 4) was a spin-stabilized space probe in the NASA Pioneer program used to investigate interplanetary space between the orbits of Earth and Venus. It was launched on March 11, 1960 from Cape Canaveral Air Force Station Launch Complex 17A at 13:00:00 UTC with an on-orbit dry mass of 43 kg. It is a 0.66 m diameter sphere with 1.4 m span across its four solar panels and achieved a solar orbit of 0.806 × 0.995 AU (121,000,000 by 149,000,000 km).

Data was received until April 30, 1960. Among other accomplishments, the probe confirmed the existence of interplanetary magnetic fields. Pioneer 5 was the most successful probe in the Pioneer/Able missions.

Pioneer (train)

The Pioneer was a passenger train run by Amtrak from Seattle, Washington to Chicago, Illinois via Portland, Oregon; Boise, Idaho; Salt Lake City, Utah; Denver, Colorado; and other intermediate points.

History

In the 1960s two Union Pacific Railroad streamliners provided service to Portland, Oregon via Boise, Idaho: the City of Portland (from Chicago) and the Portland Rose (from Kansas City, Missouri). The City of Portland had an illustrious pedigree: the first streamlined train with sleeping cars and the first streamliner in service between Chicago and the West Coast. Amtrak did not retain either train in 1971, preferring the Empire Builder for Chicago-Pacific Northwest service. Train travel between the Pacific Northwest and Denver now required going either west to California or east to Chicago.

Amtrak sought to fill this gap in 1977 with the introduction of the Pioneer between Seattle and Salt Lake City. The all-coach train operated on a daily 24-hour schedule with connections available in Ogden, Utah with the San Francisco Zephyr (Chicago–San Francisco). Meal service was provided in an on-board cafe, one of the then-new Amfleet "Am-dinettes." Coaches were all-reserved except between Portland and Seattle, where the Pioneer supplemented existing corridor service. In early 1977, Amtrak authorized approximately $500,000 to improve 13 stations along the route in Utah, Idaho and Oregon. Work included installation of passenger shelters, platforms and rehabilitation of existing stations. Regular service began on June 7.
