Design a futuristic corporate logo for a family-owned space mining company specializing in Helium-3 extraction on the dark side of the Moon. The logo should convey a sense of legacy and heritage, emphasizing the company's roots as a family business. Include elements like a stylized lunar surface, mining tools, or a futuristic spaceship, with subtle nods to Helium-3 (perhaps an atomic symbol or glowing gas effect). Use metallic tones like silver, gray, and blue with hints of gold to signify exclusivity and technological ambition. Include a tagline like "Pioneers of Lunar Prosperity" or "Mining the Moon Since [Year]." Add a modern but slightly rough aesthetic, reflecting their effort to improve despite a history of cutting corners.
