About Rocket Science

✦ AI summary

Design and assemble rockets from over 30 parts with realistic physics, then launch them to explore the solar system's planets and moons with accurate orbital mechanics and NASA-based terrain. This space sandbox lets you experience the full complexity of real spaceflight, from atmospheric reentry to docking maneuvers, with time acceleration and a scale model of the entire inner solar system.

"Rocket Science" is a declassified Soviet Union space program that aims to conquer Mars and the entire Solar system. According to official documents that have been unearthed, it consists of the following main stages:
===== Source =====
Stage 1. From 20 February 2000 \
Transfer to a designated person control of an abandoned Soviet cosmodrome located at the coordinates 50° 35' 13" N and 130° 23' 50" E ... as well as all the stockpiled spacecraft components, so that assembly and launchpad operations can be carried out in order to find optimal configurations for putting cargo and satellites into Earth and near-Earth orbit.
Stage 2. \
Organize the building of a new-generation space center on the cosmodrome site. Restrict the construction of surface buildings so as to ensure the facility's security and secrecy. Give the go-ahead for the construction and commissioning of underground facilities. Transfer the facility from state financing to full self-sufficiency.
Stage 3. \
Conduct R&D on super-heavy rockets capable of delivering equipment, cargo and people onto the Martian surface. Start building an extraterrestrial base and ensure the continuous flow of supplies to it.
Stage 4. \
===== End Source =====
Take part in the first stage of the space program right now!

Design

Assemble spacecraft and rockets from over 30 available parts with varying physical parameters. The parts can be joined together through a system of connectors and slots. This significantly reduces the number of non-viable configurations without limiting the flights of your imagination.

Launch

Put the rockets under your direct control or make flight plans and launch automated missions. But remember that going into orbit around a real planet is far more complicated than orbiting an asteroid.

Explore

You've never been on Everest? Have you dreamed of visiting the Moon? Just send a spacecraft there and enjoy the view you'll get.

Additional game features

  • The Solar system and celestial bodies are modeled to scale (currently all inner planets and their sattelites are available for exploration).
  • A physically accurate simulation of the Earth's atmosphere with a seamless transition into space will make your game session unforgettable.
  • The planets' surfaces are generated from NASA elevation maps, and a procedural approach control is used to add fine detail.
  • Realistic rocket physics and orbital mechanics.
  • Speeding up of time by a maximum factor of 10 even while the engines are running.
  • More than 75 parts are available to design your dream spacecraft: command modules, engines and fuel tanks, control and orientation systems, structural elements, decouplers and docking ports, as well as batteries and solar panels.
  • Detailed configuration of some rocket parts and the ability to change their physical parameters.
  • The engines use real fuel pairs rather than an abstract "fuel" and "oxidizer".
And much more in future updates. You can examine the development plan in the Early Access section of the game page.

Looks very promising! I do enjoy reading the Dev blogs from the Developer, it seems like he is very passionate about this game. Looking forward to seeing the progress!

i like this game a lot! it's janky at times, but thats to be expected of a game coded by one single guy. its fun! i would love for solid fuel rockets to be added to the game, thatd be a lot of coolness. also, the tutorials are pretty confusing. perhaps add a highlighted section whre you need to add the part? also, more parts would be nice, and more plane parts too. and color! thatd be fun.

Overall a good game. The rendering of most celestial bodies is mostly very accurate and stunning. There are however some issues with celestial bodies not rendering, but those are mostly objects that are in the outer solar system. My biggest regret about this game is that there isnt as many components as i thought there would be. Im willing to bet more will be added soon. As you can see i only have a couple days worth of hours on here, and i am an amateur. I wish that there was a system where you can connect two ports in a rocket payload, similiar to the lunar modules in the apollo missions. Unfortunately the community around this game isnt big, so there isnt much of a comprehensive tutorial or guide for newcomers. I still have yet to do a successful orbital rendezvous for docking. If there was an option to choose a location anywhere on earth for a space/launch center that would be great, as well as add more NASA/western rocket components, it would add a substantial amount of flavor to the game. 4/5 stars.

This game is insane, other games I can easily make it to orbit and deploy or dock... This one not so much... the delta v is more realistic ( I'm not a rocket scientist ) and the graphics are more than perfect. something about this sim just falls into place when you succeed in a journey. from what I've played so far this is like the Escape from Tarkov of space sims and I love it! Best money I've spent in a hot minute.

ABSOLUTE CINEMA for a single-dev game, keep it up
