16 авг.The Great Unconformity is a widespread gap in the geologic record where more than a billion years of Earth’s history appear to have been erased. This “missing chapter” occurs where sedimentary rocks from the Cambrian Period sit directly atop much older igneous and metamorphic rocks, often called crystalline basement. The gap reflects both the erosion of older rocks and long intervals when little or no sediment was deposited.0,00%

15 авг.Bellatrix built two. Rudra is India's first high-performance green propulsion system, delivering hydrazine-equivalent thrust while cutting handling costs by over 60%. Jal is a microwave plasma thruster that uses water as propellant, which Bellatrix claims is the world's first such system built by a private company. Both have been tested in orbit: Rudra fired on ISRO's POEM-3 in January 2024, and again on POEM-4 in January 2025. Their third product, Pushpak, is an orbital transfer vehicle the company says can bring satellite deployment costs from $45,000 to $25,000 per kilogram. In October 2024, Bellatrix signed an MoU with ISRO's commercial arm, NewSpace India Limited, to integrate Pushpak into its launch missions. The company has raised $31 million to date, backed by BASF Venture Capital, Inflexor Ventures, and Cactus Partners. For India, a domestic green propulsion stack means less dependence on imported hydrazine, lower costs for Indian satellite startups, and export-ready technology in a global market actively moving away from toxic fuels. Kalam asked Rohan to prove his concept. More than a decade later, the proof has been fired in orbit.0,00%
15 авг.In 2012, a 19-year-old aeronautical engineering student from Coimbatore presented propulsion research at a NASA event. Dr. APJ Abdul Kalam noticed, sought him out for a meeting, and handed him a recommendation letter with one challenge: prove your concept. That student was Rohan M. Ganapathy. Three years later, he and family friend Yashas Karanam co-founded Bellatrix Aerospace from IISc's incubation lab in Bengaluru. The problem they chose to solve touches every satellite in orbit. Nearly all satellites run on hydrazine, a propellant that has been standard since the 1960s. It is deeply toxic, carcinogenic, and so hazardous that it requires specialized crews and loading facilities near the launch site. India imports all of it. Nobody was building an alternative.0,00%
