Another focus has been on developing systems that will enable in situ resource utilization (ISRU) in extraterrestrial environments, which is essential for making space sustainable. This includes the company’s Blue Alchemist ISRU system, which recently completed its critical design review. This is the purpose of Blue Alchemist, which is designed to transform lunar and Martian regolith into solar power systems, breathable oxygen, propellant, metals, and construction materials. In a company press release, Pat Remias, the vice president of Blue Origin’s Advanced Concepts and Enterprise Engineering said, “Blue Alchemist changes everything about how we approach space. With the critical design review completed, Blue Alchemist will move into the next phase of development, with an autonomous demonstration in a simulated lunar environment scheduled for 2026.
