  Re: Couldn't resist
 
(...) Laws of aerodynamics (aero*dynamics*) are nothing but Newtonian physics. The whole governing equation of aerodynamics, the famous Navier-Stokes equation, is just a different representation of our well known F=ma. By the way, is it a miracle (...)

  Re: Couldn't resist
 
(...) Holy cow, it's that long?! Man, cool or not, forget that..., too long! Call me when the moon's an hour away. Now *that* would look cool, if it was the first time you'd looked up in a few days. Plus, the apparent gravity on the earth's surface (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
 
  Re: Couldn't resist
 
(...) What material would serve the best purpose for cooling off directly in space and would this material work in space to prevent the plasma that powers my space craft from overheating and making my space craft explode into a million pieces? Jesse (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
 
  Re: Couldn't resist
 
(...) You said in the last letter before this letter that some liquids (referring to the reaction to friction of certain particles in outer space) are viscious while some solids are very hard and smooth in reaction to friction in outer space. If (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
 
  Re: Couldn't resist
 
(...) Thank you for the demonstration about the vehicle and the turning into a curve, George. I finally grasp that concept in my mind. However, liquids, if you boil them, changes materials from liquids to gases, just to let you know, George. :.) (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)

(...) I get 3.5 days, ignoring the motion of the earth toward the moon. Don't worry about the cookie - LUGNET provides free cookies for us all. :) Jeff J (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
 
  Re: Couldn't resist
 
(...) Well, it's more about the angle the wing is inclined to the airflow. Just keep it tilted upward to the air flowing past you, keep your speed up, and you should get some lift. Newton says you're deflecting air downwards. Aerodynamics says a lot (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)

Narf! You're welcome. "Jesse Alan Long" <joyous4god2@yahoo.com> wrote in message news:GFnI8o.KF4@lugnet.com... -snip- (...) some fun, (...) (Perry (...) that is (...) even if (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
 
  Re: Couldn't resist
 
(...) I guess it would be based on the surface material properties. Different materials have different thermal emissivities, so picking one with a high value would be better for cooling directly to space. Of course these materials may be impossible (...)

In lugnet.space, Jesse Alan Long writes: much clipped (...) Orbit is a balance between a spacecraft's velocity and the downward pull of gravity. The vehicle's velocity pulls it outward, like centrifugal force in a car turning a corner, and gravity (...) (23 years ago, 28-Jun-01, to lugnet.space, lugnet.off-topic.geek)
