Maybe someone has already suggested what I'm going to say and if so, you can close this post. However, I found nothing on the suggestion pages and therefore decided to make the suggestion. Simplerockets allow for almost infinite possibilities since most parts can be fully customized. And this is great. Because it allows you to create great replicas of real-life space probes, for example. My suggestion is basically the following: Create a list of science pieces such as magnetometers, thermometers and everything. These pieces would have a basic model more or less as science pieces would in real life. What really matters here is the scientific research part. I'm not sure, but I imagine there are other players who like the part of unmanned spaceships with scientific equipment more. And for those who like this kind of thing, pieces of science like space probes carry would be excellent. I don't know if that text will be easy to understand. I used Google Translate.
