Why is it a rocket🚀 is used to go straight up into outer space and not just use an airplane ✈️ ? I’m sure there is a good reason but it seems that the gradual assent would be preferred over the straight up approach.

I believe that there is not air (soft material) to “walk in”. Like an engine of a boat does not have water to “walk in” outside water. Space is basically vacuum. However in another planets there may be atmosphere made of some gas(es). Thus, we can see parachutes of space probes working on mars and if I am not wrong a helicopter robot already flew on Mars (please, anyone correct if I am wrong).
