Robert M. Salter
Robert M. Salter Jr. was an American engineer who worked for the RAND Corporation. He was one of the first to study the possibility of using a satellite to collect information. During the 1970s, he advocated the vactrain high-speed transit concept. He also published papers on energy storage for the space program. Salter died in May 2011.

RAND Corporation
The RAND Corporation (from the phrase "research and development") is an American nonprofit global policy think tank created in 1948 by Douglas Aircraft Company to offer research and analysis to the United States Armed Forces. It is financed by the Federal government of the United States, U.S. government and private Financial endowment, endowment, corporations, university, universities and private individuals. The company assists other governments, international organizations, private companies and foundations with a host of defense and non-defense issues, including healthcare. RAND aims for interdisciplinary and quantitative problem solving by translating theory, theoretical concepts from formal economics and the Outline of physical science, physical sciences into novel applications in other areas, using applied science and operations research. Overview RAND has approximately 1,850 employees. Its American locations include: Santa Monica, California (headquarters); Arlington ...

Vactrain
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to . This is 5–6 times the speed of sound in Earth's atmosphere at sea level. 18th century In 1799, George Medhurst of London conceived of and patented an atmospheric railway that could convey people or cargo through pressurized or evacuated tubes. The early atmospheric railways and pneumatic tube transport systems (such as the Dalkey Atmospheric Railway) relied on steam power for propulsion. 19th century In 1888, Michel Verne, son of Jules Verne, imagined a submarine pneumatic tube transport system that could propel a passenger capsule at speeds up to under the Atlantic Ocean (a transatlantic tunnel) in a short story called "An Express of the Future". 20th century The vactrai ...

Preliminary Design Of An Experimental World-Circling Spaceship
The Preliminary Design of an Experimental World-Circling Spaceship was a 1946 proposal by Project RAND for a United States satellite program. Robert M. Salter, Jack Lipp and one other person at RAND served as the editors of the report. The Preliminary Design of an Experimental World-Circling Spaceship states, ''"A satellite vehicle with appropriate instrumentation can be expected to be one of the most potent scientific tools of the Twentieth Century. The achievement of a satellite craft would produce repercussions comparable to the explosion of the atomic bomb..."''
