Is sending something into "orbit" sending something into space?

    Space is everywhere above the Earth's atmosphere, which extends to about 100 kilometers up. To be "in orbit" means that an object is traveling with enough speed that centripetal acceleration balances out with gravity and keeps it from falling right back down again.

    Put a weight on the end of the bungie cord and swing it around. The bungie cord is like gravity, you're like Earth, and the object is like the moon or a space shuttle. The space shuttle is high enough that it takes about 90 minutes to go all the way around and it's on a very long bungie cord.

    You can be in orbit around any body. The moon orbits the Earth, both the moon and the Earth orbit the sun, and the sun orbits the center of mass of our galaxy. Only in very deep space or at special gravitational dead zones called Trojan points is it possible to escape all gravity and just sit there in true weightlessness.

    Note that you could orbit at any altitude. If it was not for our pesky atmosphere (air resistance gets in the way of traveling this fast) and trees and mountain ranges and such you could orbit within arms reach of the ground.

    Sending something into space is a general statement. Anything you are sending into orbit is actually being sent into space. The special case about being in orbit is that you are "held" in place by the gravity of the body (usually in reference to Earth) and you just circle around the planet under natural power. Sending something into space may also include going to the Moon, or into deep space such as Mars, Jupiter or beyond.

    A includes B but B does not always include A (a square is a rectangle but a rectangle is not always a square).

    EDIT:

    Not every orbit is "just outside" of the atmosphere. There are high earth orbits which put satellites in a deep orbit around Earth, typically used for satellites that need a wide coverage over the planet surface such as some lone communications or GPS-type satellites or nuclear proliferation monitoring satellites. Also, high Earth orbits are at or beyond 35800 km (the geostationary range), that is well outside of the atmosphere.

    space = 100km

    orbit = 400km (ISS)

    space requires mach 3

    orbit requires mach 30 (900 times more energy)

    yeah but its its just outside earths atmosphere. like right out side just barely in space. when its in orbit its usally revovling around the earth like satelites and when you sned something into space it going away from the earth.
