Title          
United States Space Explorations 1958 
   
 
Abstract    
The film describes preparation and launch of five satellites and two space probes during 1958. On January 31, a Jupiter vehicle launched Explorer I into space. Data from this satellite was used to identify the van Allen radiation belts. On March 17, a Vanguard I rocket launched an Earth satellite with solar batteries. Data from the mission was used to determine that the Earth is slightly pear-shaped. On March 26, Explorer III was launched to further study the van Allen belts, micrometeoroid impacts, and internal and external temperatures. Explorer IV, launched on July 26, was intended to study radiation and temperature data. A lunar probe, ABLE I, was intended to measure radiation, magnetic fields of Earth and the Moon, density of micrometeoric matter, and internal temperatures. A four-stage rocket was used in the launch. However, a turbo-pump failed and the liquid oxygen pump stopped, resulting in a failed mission. On October 10, Pioneer I was launched by an ABLE vehicle. First and second stage velocity was less than desired and the probe did not leave Earth orbit. Attempts to attain escape velocity were unsuccessful. On December, a Jupiter boost vehicle was used to launch Juno II, with Pioneer III as the payload. Escape velocity...

Title          
Test of Rolls Royce Engine for Airbus 380 
   
 
Abstract    

A Discovery Channel footage of a destructive testing of a Rolls Royce jet engine. The idea is to see if the engine suffers a destructuve failure, all the fragments from the failure (blade parts, lethal shrapnels) are contained in the engine cover. This is an important part of the testing that ensures safety for passengers.

Rolls-Royce plc (LSERR.) is a British aircraft engine maker; the second-largest in the world, behind General Electric Aviation. The company has related b...
