About Orbit One

Orbit One is a game about planning. Plan your rocket designs, plan your launches, and plan your orbital maneuvers. With careful planning, even the most difficult, far-flung space exploration becomes achievable.Start from humble beginnings and build your skills by designing simple rockets to maneuver around Earth. Demonstrate your competency with orbital maneuvering to unlock more powerful rockets with sophisticated scientific instruments. Follow your ambition to explore every part of the solar system!

Master orbital mechanics, face unstable orbits, and take advantage of Lagrange points. Orbit One's N-body physics provides a more accurate simulation than standard 2-body approximations. Orbit One's planning tools make it easy to plan and coordinate maneuvers across multiple spacecraft.

Reaching orbit has never been simpler! Use the vehicle designer to create the perfect design to fulfill your mission. Select from engines and specialized modules, adjust tank sizes and staging, and tweak the performance to meet mission requirements.Tired of flying manually? In Orbit One, the details are taken care of: launches, landings, and maneuvers are all automated. It's up to you to manage the orders for multiple spacecraft and plot an efficient, timely course.

Travel to the Moon, Mars, and beyond! Explore the moons of Jupiter, Saturn, and Uranus, or visit Neptune's icy satellite Triton.

Play through the missions to unlock larger, more powerful, and more sophisticated rocket parts. Each mission will take you further, exploring the planets and moons of the solar system. Or skip the wait and jump straight into sandbox mode and explore at your own pace.

A cautious thumbs-up, but I have stopped playing for now. I've only played for an hour, and really enjoyed it up until the end of the tutorial. After that, you are asked to do a rendezvous. I've done enough rendezvous in Kerbal that I still get nightmares involving the little widget. But that game at least had a playful interface... In this game, you're asked to do it using text fields, entering prograde, normal and radial delta-vs by hand (or scrolling up/down with the mouse). There's nothing to help you other than two sets of numbers, the goal being to make them match as closely as possible. The dreaded "this orbit, or next orbit, or the orbit after that, or..." is handled with two buttons (you can guess what they are). A typical rendezvous will require a number of these manoeuvres, so that adds up to a lot of "fun." There are 3D graphics going on the background, but they aren't much use when you are interacting using text boxes. The fun part about Kerbal rendezvous was what happened when you got within 10km. Getting there was tiresome and repetitive. This game has automated the fun part (within 10km), and left the dull part for you to do. Given orbital ren…

I get that N-Body physics is hard on compute but this game is fundamentally buggy at release. The core function of orbital mechanics is broken

I am a Kerbal space program fan. Compared to KSP this game is less vehicle centric and I think its fine. Its still a bit crude but it has potential. Few comment: Even if the game is less focused on the rocket I would like to have a deeper vehicle builder. Visual that reflect the actual shape of the rocket would be nice to. The game seem to be entirely pre scriped mission. There is no generic satellite launch. No playload to launch in the sandbox mode and more importantly no incitative to optimize your launcher. Without these Launcher design is a tad boring. Longer construction time for bigger rocket might be enough, but I think adding money too would be better. The game need delta-V per stage. A way simulate playload mass during design. Smaller engine for last stage (atm lander/satellite are the last stage). I am sure those will come in time. Atm there is few bug. The most annoying is the trajectory bug. I am not sure if its the N-body or the orbital decay. Either way trajectory prediction should be more accurate and orbital decay should be slower (or have a automated reboost function to counter it).
