Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Ah, so you'd need an impulse around the apogee, and acceleration around just the perigee can't create a stable orbit? Makes sense, thanks!

Thats what I remember, someone who plays KSP will probably be along to telle what I forgot.

I was just thinking this conversation is clear who has played KSP.

Simplified, you have a rocket orbiting around the earth going over both poles in a circular orbit. Above the north pole its 250km high and fires off its rocket all at once. Now its orbit is an eclipse going to 500km above the south pole, but it will return to 250km above the north pole. If you want to increase your altitude over the north pole you would need to accelerate above the south pole.

Orbiting is much more about going really really fast than it is about going really high up. Vast majority of the acceleration of launching into orbit goes into acceleration parallel to the ground rather than lifting away from it.
