B Methods of accelerating in space?

  1. Nov 4, 2016 #1
    hello !

    I was thinking about some ideas of new ways to accelerate spacecrafts in space, but for that it would be helpful to know which methods are currently in use. I'm talking about the acceleration in general, so both at a place in space influenced more by gravity ( like earth orbit ) and a place without that much of a gravity influence ( if that makes a difference in how to accelerate)

    Some that come immediately to mind are:
    Traditional rocket propulsion with gas
    Rocket propulsion with ion propulsion (see http://www.nasa.gov/centers/glenn/about/fs21grc.html )
    "Sails" to catch solar wind. (see http://www.nasa.gov/centers/marshal...sting-of-revolutionary-e-sail-technology.html )
    Gravity assist "sling shot" around a fast moving planet. (see https://solarsystem.nasa.gov/basics/grav/primer.php )

    BINGO! Here is a good reference: https://www.nasa.gov/pdf/501329main_TA02-InSpaceProp-DRAFT-Nov2010-A.pdf
