@Azel If you've got a moment, I wanted to talk about space mechanics. I think there was some (pseudo?)scientific speculation about how a ship going really fast could avoid splatting against small debris. Though I'm wondering if that was just for really, really high speeds or to what degree one would have to worry about a moving object's durability generally not being able to take hits like that consistently without hull breaches occurring... that honestly requires more physics talk than I'm comfortable with.
Some kind of energized sheath for the front of the ship, like a plow, or a gravity manipulation trick...
I was going to suggest something deflecting average micrometeorite impacts with constant use of Brilliant Barriers at the least, though that's not really wholly a travel concern. I get the impression that would more than deal with them though, since apparently we build our spacecraft such that the overall impact of impacts over time is described as "sandblasting"? And real materials used in them aren't generally harder than aerospace grade titanium.
This might all be redundant if it actually takes a really long time to pick up any appreciable speed, but if the speed builds up at a reasonable level in-system exploration might be a possibility at the very least. I'd bet on at least half the people here being curious about surveying some gas giant moons, or trying to mine asteroid belts for metamaterials.
Edit: A whipple shield! Forgot about those. And it's a practical engineering idea too.
Alright, a few things:
1. Everything in space is really, really fast. Maintaining an orbit close to earth means you are going at 7.8 km/s. Everything that is in a stable orbit thus will be very fast. If that is dangerous or not depends on the relative orbits. If you have an orbital inclination of 0° and hit something flying in a 180° orbit, you will collide with a relative speed of 7.8 + 7.8 = 15.6 km/s, which means a lot of energy. This turns specks of dust into bullets and a bowling ball would hit you with enough force to be measured in kilotons TNT equivalent.
2. Space is big. Really, really big. The odds of meeting, let alone hitting anything out there without trying to is absurdly small, unless you are diving into a field of debries.
3. Planetosi space should be entirely clean. Earth space is littered with the remnants of human space exploration, which is where all those dangerous things come from, but Planetos should have none of that.
4. Space debris are not Mindblanked. You can simply divine a hit in advance. The House of Mirrors can provide that service easily, giving ample warning ahead of time.
5. A Brilliant Barrier is a force effect and will stop any kinetic impactor dead in it's tracks. If you have divined that a hit will occur, all you have to do is to get up a Brilliant Barrier and let it hit that instead.
6. Thrust of a Moonchaser is indeed a bit low compared to rocket powered space-craft, but still much higher then that of ion-drive crafts. You need a bit more time to make large changes in velocity, such as initiating a Planetos -> Moon transfer, but we are talking about something that took Apollo 11 a few minutes taking the Moonchaser a hour, maybe two. Space exploration is easily possible.
7. The thrust characteristics of the Moonchaser change a bit depending on where you are in the system. This is, generally speaking, complicated, but no hindrance to exploring space. We will learn a lot about physics from examining why the engines keep doing weird stuff for no apparent reason. The astronomy department of the Citadel will go green with envy, get an ulcer from rage, or both.
8. Transfers to other stellar bodies take a long time. A transfer from Earth to Mars takes about 260 days and that is when you launch in the optimal time window. Said optimal window happens every few years. Such optimal transfer windows to other stellar bodies, such as the gas giants, are significantly rarer.
Overall, I would suggest focusing on getting a space station built and that network of spy satellites. Then do some exploring of the moon on the side.
