Easy Deep Impact Achievement Guide
By HelgiRalfarsson
This guide will help anyone struggling with getting the Deep Impact achievement as all of the steps are easily executable without any complicated ship maneuvers. If you can press and hold one button for a few minutes and then switch to pressing and holding another button for a few more minutes, you will easily get this achievement.

Introduction
The description for the Deep Impact achievement is: "Enter Giant's Deep ocean fast enough to break through the current." While there are certainly other creative methods that also unlock this achievement, this method is by far the easiest to perform and this guide will trivialize any of the tough piloting normally required to maintain a collision course with the planet.
Overview
In order to build up enough speed (10,000 m/s*) to break through the current, the ship must be more than 1,000 km away from Giant's Deep before accelerating toward the planet. However, care must be taken that the ship isn't too far away from the planet as too much velocity (12,000 m/s) will cause the ship to clip through the planet completely. If you start from the surface of Giant's Deep and use the landing view along with the up and down thrusters exclusively to pilot your ship, you will perfectly preserve the path your ship needs to take by completely eliminating two whole axes of movement. As stated in the description of this guide, if you can switch from holding one button for a few minutes to holding a different button for a few more minutes you'll easily get this achievement.

*(NOTE: If you are running at an FPS faster than 144, consider lowering your FPS to 60 to get this achievement as 10,000 m/s may still be too slow to break through the current. A more detailed explanation can be found in the section "A Note on FPS".)
Method
1. Enter Giant Deep's atmosphere and scope out a clear area in the water away from any cyclones and islands to land your ship.

(NOTE: While it may be possible that the spot you choose will put you on a collision course with a heavenly body such as the sun, bear in mind that this is very unlikely. Don't get discouraged if you have to try this method more than once to succeed.)

2. Switch to the landing view and wait until the core of the planet settles into the middle of the viewing window. Ensure Giant's Deep is targeted in the viewing window.

3. From the surface of the water, engage and continue to engage full up thrusters for a few minutes as your ship accelerates away from the planet and towards the starting position of 1,000 km away.

4. As the ship gains speed it will soon be traveling very quickly away from Giant's Deep, so you will need to start decelerating when it is still several hundred kilometers away from the starting position. Monitor the distance it travels through the viewing window and wait until the ship passes 500 km away (with a speed of roughly -7,150 m/s) before switching from full up thrusters to full down thrusters. Although the ship will continue hurtling away from Giant's Deep, it will eventually slow down until it stops at roughly 1,030 km before beginning its descent toward the planet. Continue to engage full down thrusters for a few minutes until the ship crashes through the current and you get the achievement. If performed correctly, you should hit the required 10,000 m/s while still several kilometers away from the planet.

Ship at a starting position of 1,034 km away with a speed of roughly 0 m/s and beginning its descent:

A Note on FPS
The exact speed required to break through the current seems to vary depending on the frame rate with 30 FPS requiring as low as 5,000 m/s while 144 FPS requiring a full 10,000 m/s. For the purposes of this guide, 10,000 m/s will be used as this should ensure most people hit the speed required regardless of graphic settings. As some have reported 10,000 m/s is still an insufficient velocity on certain setups, bear in mind that if you are running at an FPS faster than 144 you may need to manually lower your frame rate as velocities faster than 12,000 m/s run the risk of clipping through the planet entirely.
Conclusion
That's pretty much it. Leave a comment below if you have any suggestions on improving this guide or if this method didn't work out for you. Thanks, and I hope you get the achievement!

A really well made guide, i especially like the style how you kept it informative but short and redirect to more detailed info at the end of the text.:cozyjunimogreen:

I did this with 144 fps. Let me tell you. The speed this bad boi boat can reach.

when I first got the game this was my first thought, when I did it I hit an island

I unlocked this achievement accidentally lol. I was trying to figure out how to enter the current (I didn't know about the whole reverse tornado thing atm). So I waited for one of the island to be lifted up by the tornado, then put my ship underneath the spot where the island would fall back down. As a result, the island when it fall down pushed me and my ship through the current and almost completely destroy the ship in the process.

what are the other ways?

Nevermind Helgi Ralfarsson, I tried it again and got the achievement no problem. Guess it was just bad luck

Tried this multiple times, even limited my FPS to 30, still wont get through...

Have you tried more than once, EnragedFerret? Chances are you were just unlucky with the way the planets lined up.

I did everything the guide says, but when I re -enter the solar system, I get pulled off course by the other planets and fly straight past it

Oh yeah definitely unlucky I know. Was just pretty funny to be both violently exploded and ejected from the planet within 10 frames of entering the atmosphere. Especially since the islands only make up like ~5% of the planet lmao. Safely dove beneath the current on the second attempt
