  • Spaceflight news
  • Questions, comments, corrections
    • Some nice tidbits from /u/Jakesparklechicken
      • The way Isp is expressed results in an interesting relationship
      • It’s the amount of time it takes to expend a mass of propellant “equal” to the thrust of the engine
      • 1N engine with an Isp of 200s will take 200 seconds to burn through 1kg of propellant
      • Newton is Kg * m * s2
      • Atlas I and II used the stage-and-a-half configuration because air lighting a liquid fueled engine was not a problem that had been adequately solved in '58
      • HT Sam Moore for this great resource on MA configurations (http://www.b14643.de/Spacerockets/Specials/Atlas_MA-drive-system/index.htm)
      • Prior to the Lundin report that cemented LOR as the mode for the Apollo missions, they actually studied a fourth mode, Lunar Surface Rendezvous.
