Homework Statement
Okay...So why does NASA launch in the east. Is there an advantage in east from west?
As you suggested in post #3, it's to do with the way the Earth rotates.Ignis Radiis said:no, I meant like, when they launch satellites or rovers onto other planets, they usually launch it east.
Thanks! I get it now...haruspex said:As you suggested in post #3, it's to do with the way the Earth rotates.
When launching an object into space, what is the main challenge?
If you are on a train going at 90kph and throw a stone forwards at 30kph relative to you, how fast is the stone going?
Yes. But before they head off into the outer solar system, where do they go? Where do ALL vessels launched from Earth go first?Ignis Radiis said:no, I meant like, when they launch satellites or rovers onto other planets, they usually launch it east.
Tooooo the atmosphere?DaveC426913 said:Yes. But before they head off into the outer solar system, where do they go? Where do ALL vessels launched from Earth go first?
To orbit.Ignis Radiis said:Tooooo the atmosphere?
right...DaveC426913 said:To orbit.
And what do you need a lot of in order to stay in orbit?Ignis Radiis said:right...
Gravity?DaveC426913 said:And what do you need a lot of in order to stay in orbit?
Wouldn't gravity would do the opposite of keeping them in orbit?Ignis Radiis said:Gravity?
Their free fall?DaveC426913 said:Wouldn't gravity would do the opposite of keeping them in orbit?
What keeps them up there despite gravity?
What is free fall? What is counteracting gravity?Ignis Radiis said:Their free fall?
I'm lost...DaveC426913 said:What is free fall? What is counteracting gravity?
Look at haruspex' post #9 for a hint.
Momentum? Specifically Angular Momentum?DaveC426913 said:What is free fall? What is counteracting gravity?

Simply: speed. You need to be going several miles per second to stay in orbit.Ignis Radiis said:Momentum? Specifically Angular Momentum?
