A simple challenge for those who claim they like topics related to space exploration

Every body floating in space, is ALWAYS in an orbital path. There is no such thing as "steadily floating around in the middle of space"...everything is in motion and is on some orbit.

"Everything is always falling towards something significantly much larger than itself."

i agree with this, mr.rodsky. everything is in motion.

Ok bro here it is...

Shuttle is orbiting around the earth in a fairly circular orbit of about 310 kilometers (highest point of orbit, called the apoapsis) and 302 kilometers (lower point, the periapsis). Yes, it's not a perfect circle, but near perfect.


Shuttle begins its prograde burn. It doesn't gain any speed at this point. Instead, it basically will introduce changes to it's orbital path...


...as shown by the green dashed line here...


...and a few minutes later, the orbit still elongates...


...and a few minutes later, the orbit still keeps elongating...


...still a few minutes later, the orbit still keeps elongating...until it becomes a long ellipse.


So, basically, if it keeps burning, it still simply just increases the apoapsis, but the periapsis remains the same (at 302 kilometers)...meaning, the apoapsis may be as long as the distance from the earth to the moon (HINT: Now you know how to reach the moon! hehehe), but the periapsis still remains to be nailed down at 302 kilometers.

This is why, any body floating out in space, is always "anchored" to some other influential large object. Like the moon is to the earth, and the earth is to the sun, and the sun is to it's sister stars, and this cluster to the milky way, and the milky way to the local group, and the local group to the supercluster...and so on.

Now let's go back to the last diagram.

Even if the shuttle suddenly stops its engine at this point (say, it has run out of fuel), that green orbital path will still be its new orbit. So perhaps, several hours from now, the shuttle will be here...



...and many more hours later, it will just coast back until it speeds on down back to an altitude of 302 kilometers from the earth's surface, and then go around again. The only time it can circularize this orbit, is if it does a retrograde burn back at the periapsis point.

That's Carl Sagan talking. Yes I find it entertaining. Perhaps others won't.

The whole COSMOS series spanning from Episode 1 to Episode 13, hosted by Sagan, is a pretty informative series. Which is why, even though it was made back in 1981, it's still very popular these days.

i agree with this, mr.rodsky. i've read of something similar like this in a book The Universe and Dr.Einstein. i forgot the author, though.

how brilliant rodsky! can't understand any better than this. thank you kaayo. now i can travel to mars!

You're welcome bro. Honestly, the farthest I've gone in Orbiter is the moon, kay it's only 2-3 days away. With currently available human-capable thrust, Mars is over 9 MONTHS away (yikes), so even with accelerated time in a simulation, it would still take A WEEK or more to get to Mars, and frankly I don't have that much time to stare in front of the computer

Earth to the moon, and back however, is pretty fun

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