English: The Power for Flight is a survey of NASA’s work in aircraft propulsion from its origins as the National Advisory Committee for Aeronautics (NACA) to the early 21st century. It introduces NASA’s role in the technology while taking into account economic, political, and cultural dimensions.
Orbital Mechanics for Engineering Students is an aerospace engineering textbook by Howard D. Curtis, in its fourth edition as of 2019. [1] The book provides an introduction to orbital mechanics, while assuming an undergraduate-level background in physics, rigid body dynamics, differential equations, and linear algebra.

Another Disclosure Project whistleblower, Philip J. Corso, stated in his book the craft retrieved from the second crash site at Roswell, New Mexico, had a propulsion system resembling Thomas Townsend Brown's gravitators. [14] And, Corso's book featured several gravity control propulsion statements made by Hermann Oberth.
With a conventional chemical propulsion system, 2% of a rocket's total mass might make it to the destination, with the other 98% having been consumed as fuel. With an electric propulsion system, 70% of what's aboard in low Earth orbit can make it to a deep-space destination. [24] However, there is a trade-off.
Greater flexibility in lunar orbital or landing site coverage (at greater angles of lunar inclination) can be obtained by performing a plane change maneuver mid-flight; however, this takes away the free-return option, as the new plane would take the spacecraft's emergency return trajectory away from the Earth's atmospheric re-entry point, and ...
Bell Aerosystems began development of a rocket pack which it called the "Bell Rocket Belt" or "man-rocket" for the US Army in the mid 1950s. [1] It was demonstrated in 1961 but 5 gallons of hydrogen peroxide fuel needed for 21 seconds of flight time did not impress the army.
The Journal of Propulsion and Power is a bimonthly peer-reviewed scientific journal covering research on aerospace propulsion and power. The editor-in-chief is Joseph M. Powers (University of Notre Dame). It is published by the American Institute of Aeronautics and Astronautics and was established in 1985.
