keep dreaming, rodsky. you'll never leave earth.

Fully aware of the fact, but thank you for the heartfelt reminder.

anytime, mr.rodsky. anytime.

Which brings us to the third question for this thread (and it's quite a simple one at that, because it's related to the diagrams I just recently posted, re the shuttle's ever increasing elliptical orbit):


Starting with this image, how then, does the shuttle return to earth?

The hints are already scattered all over the thread, but the most recent illustrations will help a great deal at answering the question.

ang speed sa satellite kay iadjust so that it falls to earth at the rate faster than that of the curve of the earth falls away from the satellite.

Do a retrograde burn - shuttle to turn 180deg and fire engine till the right velocity(smaller from the initial V) is achieve so that the trajectory will take you to earth's surface(smaller ellipse now as a result), then shuttle turns around again for re-entry sa atmosphere, and air resistance will do the rest. Since mo glide ra man ang shuttle towards its landing area, kailangan naka plot na ang trajectory to the landing area..

Hey rodz, though i answered some, i still have a lot to learn! please continue to teach! thanks!

Correct answer. I'll post a diagram of your explanation later

*nosebleeds on prograde and retrograde* but i'm learning.

Great find ethz Basically, reading that link and absorbing it well, will enable anyone to answer the three questions I posted with relative ease.

true.

Now the mathematics part: Basic of Space Flight: Orbital Mechanics

Hope this helps.

You are on the right track as well, but remember, the ISS has no capability to change its orbital radius. Only the shuttle can, in this case.

But again people, let's go back to the original question--simple ra man ang original question...does the shuttle need to do what the F-16 did, to reach the ISS? Yes or No, and then explain why. Kana ra man ang question

-RODION

ah..so ang shuttle ang mg adjust ug orbit?so lower xa una para maka apas xa den..change napud ang orbit?
