    Most rockets are designed to not rely on aerial flight to provide lift. Because of that, it is more efficient to point the rocket “up” in locations of thicker atmosphere to reduce fuel burn in locations of high air drag.

    If you point the rocket slightly above horizon, a lot of the rocket’s energy gets lost in overcoming air drag.

    If you point the rocket below the horizon, the rocket’s energy gets lost in resisting the drag of the ground.

    Because the word “up” literally means “away from the planet” you will not find a single point on Earth where there is not exactly one general direction clearly definable as “up”.

    But to get personal with you, I don’t put any stock in the opinions of people who unironically say “if Earth is round…”. This reply is for the poor souls who had to read your post due to my additional downvote not having saved them from it.

      Bs

      I can go away from earth downward from earth too.

      Truth can’t be hidden for long.

    We do send them both left and right (west and east), as well as north and south. That’s how you get to orbit. Mainly east to take advantage of the earth’s rotation (can’t think of a good reason to send them west, other than suborbital/ballistic flights. Maybe it’s been done for orbitalrockets, I never checked). North or south for polar orbits.

    Each of those flights start by going up in order to clear the thickest part of the atmosphere. If you watch a rocket launch long enough, you’ll see it slowly start pitching down after a while in order to gradually oriented towards horizontal flight, this is called a gravity turn.

    As for down, well… you will not go to space today.

    The shortest path away from earth into space is by going radially outward i.e up.

    Yes the direction of “up“ depends on where you are on the earth. “Up“ on the south pole points in the same direction as “down“ on the north pole.

    When we lauch a rocket into space it’s actually sent on an eastern launch. It gets a small boost from the spinning of the planet when launched that way.

    Also, just to be clear: The earth is round. This is a proven fact. You must first understand this or the entire premise of your question fails.

    Any angle other than away from the ground tends to lead to a result known by rocket scientists as “Lithobraking” and “A rapid unscheduled disassembly”

    Seems like this would be better addressed in nostupidquestions because if I’ve ever read a stupider question, this would still be the stupidest question ever.

    So far.

    If earth is round

    🤨

    Anyway, we do send rockets left or right. It’s required to get into orbit, since basically orbits are something moving fast enough sideways so that it always misses Earth. We don’t send rockets down, obviously, because that would be into the ground. But if you’re talking in cardinal directions then yes, we do fly rockets in all directions. Polar orbits are called that because the satellite flies north- or southwards.

    The reason why rockets launch facing up (opposite gravity; not north) is because it’s more efficient to leave the thick parts of the atmosphere before getting most of your speed because of drag. You could launch a rocket parallel (tangential) to a point on Earth it’d just take a lot more fuel. Space planes do technically launch like that, but they use the atmosphere to their advantage by using wings (lift) to gain height.

        There’s ground below every point on Earth. There just might be some water on top of it too. Also Antarctica is a continent with ground underneath the ice. The North Pole is the one without ground (immediately) below it. Hence the Arctic Ocean on maps.

            Which ice wall? There are lots of walls of ice in the world. The South Pole is in Antarctica which (depending on where you approach it from) can look like a wall of ice.

              Nahhh man, those are different things.

              There’s Antarctica which is (depending on where you approach it from) might look like a continent, but is actually an ice wall.

              Then there’s the South Pole. South Pole is in the bottom part of earth.

              Those are different things.

                No, Antarctica is a continent which contains the South Pole. People have been to the South Pole, if Antarctica were actually just an ice wall the South Pole would not exist and so would not be possible to visit.

                  People have been to the South Pole

                  Nahh, people have been to Antarctica and they lied they’ve been to South Pole.

                  South Pole is in the bottom. That’s why it’s hard to visit. You’d either have to drill your way there or get out of the atmosphere and go downnn

    To break through the atmosphere we gotta go on an angle the way the earth spins, or do you mean rockets to blow up stuff on earth?
