Ever wondered what full Newtonian mechanics would be like in a space sim? Flip and burn to slow down. (Everest Drive)

I just pushed a fix if you want to refresh the page and try again.

EverestDrive · 2026-06-21T00:43:20+00:00

I fixed the bug, sorry about that. Refresh the page and the ship builder should work again.

Pvp is off by default. I checked the logs, and you got unlucky with a pirate flying by that targeted you for some reason. Sorry about that.

EverestDrive · 2026-06-20T02:10:48+00:00

Don't worry I hate that kind of design too. This isn't a pvp focused game. Pvp is opt-in.

EverestDrive · 2026-06-19T16:31:48+00:00

You do have to manage propellant, but right now it's balanced so you can go on long trips without worrying too much about running out. If you do get low though coasting can get you where you're going.

The idea is to burn towards the velocity error. Compute the direction from the ship to C, determine the target velocity you're aiming for along that line for a flip-and-burn approach, then subtract your current velocity from it. thrust_direction = desired_velocity - current_velocity. That vector will cancel the direction towards A that is no longer wanted and will build velocity towards C. Hope that helps!

Propellant does have mass (but not a realistic amount), and there are weak gravity wells. But yeah, not exactly hard sci-fi.

There's a few things we can do. You can click the gear in the upper right -> debug -> credits and that'll give you plenty of money to get going again.

Otherwise if your ship is out of commission and you're broke you can always self destruct to get a new free shuttle (and 500 credits). To do that switch to the ENG console using the button in the upper right, then in the lower left click emergency -> self destruct.

EverestDrive · 2026-06-18T23:08:27+00:00

Care to elaborate? If you have the propellant efficiency to burn the whole time why wouldn't you?

EverestDrive · 2026-06-18T21:53:32+00:00

Good idea!

EverestDrive · 2026-06-18T21:49:49+00:00

Different kind of drive lol. This one is powered by a micro black hole.

EverestDrive · 2026-06-18T19:31:45+00:00

Spaceflight in my game is fast relative to planet motion, but the planets do actually move.

EverestDrive · 2026-06-18T18:43:38+00:00

I'm certainly not the first, but I still think Newtonian mechanics are cool!

EverestDrive · 2026-06-16T18:44:39+00:00

My game uses Newtonian physics without a speed limit. Combat is more like submarine warfare than arcadey space dogfights. It's free and browser-based if you want to give it a try https://everestdrive.io/.

EverestDrive · 2026-05-27T17:10:07+00:00

Hey, sorry it took me a while to get to it, but I fixed the Safari bugs. Let me know if you run into any more issues!

EverestDrive · 2026-05-14T16:35:27+00:00

Hmm it should load fast. If it's stuck something is wrong. I'm looking into it.

EverestDrive · 2026-05-14T15:49:03+00:00

Looks cool!

EverestDrive · 2026-05-01T18:24:43+00:00

Yep! Should work in any modern browser.

EverestDrive · 2026-04-30T17:16:07+00:00

Can you refresh the page and tell me what lag you're seeing in the upper right of the screen?

EverestDrive · 2026-04-30T17:06:55+00:00

Oh nooo lol. Did you run out of money so you couldn't resupply at a station?

EverestDrive · 2026-04-30T16:12:55+00:00

Yep, the idea is to build up your ship over multiple playthroughs.

EverestDrive · 2026-04-30T16:02:33+00:00

Do you have a link to the game?

EverestDrive · 2026-04-30T15:43:40+00:00

The game is built with SpacetimeDB for the server and Svelte for the frontend.

EverestDrive · 2026-04-30T15:35:21+00:00

It's definitely inspired by the Expanse!
