In 1923, the German scientist Hermann Oberth published his study 'The Rocket Into Interplanetary Space'. This introduced the idea of a telescope able to view the universe unhindered by the Earth's atmosphere.
This technical documentary [1970s, early 1980s?] looks at the advantages of such a telecope, and outlines NASA's plans to build and deploy one. Includes: shots of observatories, astronomical photos; the concept of pbserving galaxies that may be billions of light years away; spectroscopical analysis of the electromagnetic radiation which reaches the Earth; advantages of placing a telescope outside the Earth's atmosphere [i.e ten times clearer]; an explanation of how the telescope will work; illustrations to explain the mission; interviews with various scientists and astronomers; an explanation of what the telescope will tell us.
