🧪 Space Technology Simulator with Data-Driven Mars and Satellite Missions

This simulation provides a detailed exploration of rocket technology by allowing users to design rockets, simulate launches, and analyze their flight paths within a realistic orbital environment. It focuses on the core principles behind spacecraft propulsion and orbital mechanics. The Mars Mission and Satellite Deployment tabs previously had a Launch Window and a Satellite Type select that were never read, plus three buttons that only popped up a hardcoded canned alert. Launch window now changes the computed transfer ΔV and travel time, satellite type changes the deployed satellite's color and solar-panel size, and the deployment-altitude slider now actually repositions the satellite on the canvas and affects the reported signal strength and latency.
