In science fiction = straight. earth is in orbit, you in space are also in an orbit. If around the earth = gradual curve. Apply thrust and off you go on another orbit. Play with kerbal space videos = get the idea

Most? Other than a few probes in polar orbit around the sun, I don’t know of any reason or target to go “up or down”.
Yes, i know the correct term is north/south.
To add on to other peoples answers, within our own solar system everything is for the most part going to be on the same plane +/- a certain amount of degrees because of angular momentum when the solar system first formed. There might be other systems that are “up” and “down” but intentionally reaching other systems is out of mankind’s scope for now.
Well, we have some polar satellites, and those go 'up/down,' but for the most part, all planets are roughly in the same disc, so that's where we aim our spacecraft. Juno had to move along that path to reach Jupiter, but its orbit is polar, and highly elliptical.
But spacecraft don't go straight, their trajectories curve, and it takes less energy to follow the path of Earth's rotation/orbit than it takes to go perpendicular to it.
How did you conclude that we "go in a straight line straight ahead"?
Take a look at this 3d map of the solar system. Almost everything interesting is "straight" or close to.
https://theskylive.com/3dsolarsystem Why would we explore empty space? We are always going towards something not towards nothing
That map is great, I learned about comet 5D/Brorsen.
Space is hard for the human Brain to comprehend its doesn’t have a up or down
There are a handful of comets and asteroids that orbit far off the ecliptic plane.
I stand corrected. Comet C/1858 L1 (Donati) has an orbital inclination of 116.95 degrees = 90 + 26.95. Such a high inclination is both rare and interesting.

Most of the interesting things are on the plane where the solar system orbits the sun. There's not a lot of reason to go "off the disc", and there has to be a reason in space travel, since resources are so scarce and costs are so high.
