An engine only in the Sandbox that never ran out of fuel. It would be EXTREMLY useful when completing large orbits.

For example: once clicked an overview tab would come showing the key info on an item, such as it's mass, This would be good for the engines as it could also show the rate at which they burn fuel. i.e. Blasto 425 burns at 125 L/s @100%.

maybe. just an idea

When you land somewhere that is not a starting location e.g. Ganymede jr or Smalleys Comet, you "unlock" the location and can start there

Make it as a % of the main thrust, or make different sliders.
Make it possible to have engines stay at a certain % while you control others

Would make some zoomed in orbiting easier to see.

Make the space exploration not only limited to our solar sistem, put more stars farther away with planets to make the game more diverse. You will need to put more warp speed so it does not take all the time needed to go to another star! It also could also be that when you arrive to another exoplanet you colonize it and can launch from it.

Android devices have an build in file browser and iOS can have that too with jailbreaking, so installing mods shouldn't be impossible.

Allow autopilot to use RCS to match speed and velocity with your station, the catch is you have to be close enough to tap the ship in the normal view. Zooming out counts.

Currently the line stops at the sphere of influence when encountering a planet. If the line continued to show what would happen after that point, the physics engine could be used to plan for gravity slings or less fuel needed to enter an orbit.

Landing on other planets
Landing rovers
Making a return trip from the moon
Smupiter altitude challenge
Add comets
Change starting position of orbiting bodies
Add more moons
Etc..

Please for the sake of all man and woman kind fix the orientation.. Landing a rover on Saturn upsidedown is unnecessary!!

Great game, thanks!!

Make a system that you need to go to planets, then there. Do research on the ground and air to earn EXPERIENCE. With EXPERIENCE points you can buy NEW PARTS,

With the ability to play on the same save indefinitely coming up, I'd like to keep old rocket parts. Maybe space junk would even become an issue.

Where you can build simple missions
1) Pick what planet to launch from
2) Pick what planet the player must get to
3) Pick what to do at that planet (orbit or land)
4) Choose how to rate performance (Time or Fuel usage)

During docking, this would be very useful. If you double tap on another vessel within range, you should be able to switch to it.

when you come encounter it you can click "automatically dock"

1: use multiple command pods in rocket design
2: more re-entry challenge
3: on-surface base components
4: floating components
5: chance for a mechanical (possibly repairable) breakdown, costing time to fix

thank you :)

I think that will be good, if there will be individual keys for expanding and folding parachutes because detaching them means that they couldn't be use again so players will need to increase weight of rocket by adding other parachutes, landing legs etc.

Design your rocket part and apply simple rocket settings. And can share that on the simple rocket website. Hope you understand this.
