• The integration of AI and Machine Learning in space power management is a key market trend. This has enabled real-time energy optimization, predictive maintenance, and adaptive control that greatly increases expected reliability, resiliency, and efficiency for longer-duration spacecraft missions, which has started to be putting into practice in the early 2020s and expects to peak between 2025 and 2030 with the accelerating AI models, algorithms and computing processing capacity.
   
• NASA has initiated AI and ML into over 400 projects related to everything from image recognition, and atmospheric modeling, to predictive analytics - many mission-supportive applications. This will help improve the efficacy and reliability of space power systems.
   
• The integration of renewable energy, particularly space-based solar power (SBSP), into space power supply systems is a rising trend gaining momentum since the early 2010s. This trend highlights the demand for energy that is continuously generated, clean, and efficient in space and on earth driven by environmental responsibility, technological developments, and a rise in missions to and from space.
   
• It is expected to peak from 2030 and 2040 as efforts ramp up and commercial deployment increases. For example, the Hubble Space Telescope uses two gallium-arsenide solar panels that are 8-by-25-feet and produce about 5,000 watts of power. These panels have approximately 30% less area and produce as much as 20% more power than silicon-orthodox flat panel solar cells.
