About Stellar Discoveries
Stellar Discoveries P.C. is redefining the future of human space exploration with a ground-breaking combination of planetary science, biochemistry, astrobiology, and advanced engineering. We pioneered the study of cosmic radiation and micrometeorite impact-induced soil/dust oxidants, as well as the monitoring and mitigation of their negative effects on astronaut health and space missions, while also leveraging some of them positively. Our products and services are numerous: Sensors for monitoring space oxidants and their negative effects on astronaut health (by medical sensors), base stations, spacecraft, rovers, and space habitats, dust filtration systems, water/food supplies, equipment, extraterrestrial life biosignatures, and also on Earth's space and microsatellite ecosystem (in Public Health and Civil Protection from atmospheric pollution with dusts from Africa/mines/wildefires/space debris/volcanoes, inefficiency of all air/dust filtration system types, nuclear/radioactive/UV-solar radiation, etc.). We produce cosmic dusts and environments of all kinds with ultra-high simulation fidelity (in texture, physicochemistry, oxidant activation) to model the negative effects of oxidants on space missions and astronaut health. We also develop antioxidant strategies and dietary supplements for astronauts, and provide research to mitigate the negative effects of oxidants in soils and dusts, as well as of cosmic radiation, on space missions and astronaut health. Additionally, we utilize planetary oxidizers to produce oxygen for astronauts and to predict earthquakes, and ensure their preservation during sample return missions from the Moon and Mars.
