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.

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.

Eggs are one of the most debated foods in Ayurveda. Ayurveda does not outright ban eggs but it classifies them as Tamasic food, recommends them primarily as a therapeutic remedy rather than an everyday staple, and insists they be prepared with specific spices and cooking methods to minimize doshic imbalance. Vagbhata's Ashtanga Hridayam, Sutrasthana Chapter 6 echoes similar classifications, grouping eggs among substances that are guru (heavy), snigdha (unctuous), and madhura vipaka (sweet post-digestive effect). Vagbhata emphasizes that such foods are best consumed in winter seasons when digestive fire (Agni) is naturally strong. The critical takeaway: Ayurveda does include eggs as a recognized food category, but treats them more as a medicinal food (Aushadha Dravya) than a daily dietary item.

For decades, the standard critique against the Indian Knowledge System (IKS) was: "Where is the empirical data? Where are the peer-reviewed papers? It is all just mythology." Now, when institutes like the IITs, IISc, & AIIMS are setting up dedicated research wings to rigorously test, validate & document these ancient sciences using modern, empirical protocols, the critics have panicked. They have switched from demanding proof to screaming "pseudoscience!" & "the brand is gone!" For centuries, Western medicine dismissed the idea that the mind could heal the body as superstition. Today, neuroplasticity & the placebo effect are multi-billion-dollar fields of peer-reviewed research. If a modern scientist discovers something new, it is called a "breakthrough." If an IKS researcher uses modern tools to prove that ancient Indians already knew that exact concept 1000s of years ago, it is called "pseudoscience." In 2015, the Nobel Prize in Medicine was awarded to Tu Youyou for discovering Artemisinin (an anti-malarial drug) by looking into ancient Chinese medical texts. Similarly, India’s Ayush research ministries & global pharmacological bodies are finding peer-reviewed validation for compounds like Curcumin (Turmeric) & Ashwagandha for their anti-inflammatory & neuroprotective properties. Why do these people have a problem with India documenting its own heritage? If China can globally brand Traditional Chinese Medicine & the West can capitalize on indigenous knowledge, We have every right to scientifically document our own Itihasa & knowledge systems. Demanding peer-reviewed papers for decades & then throwing a tantrum when India actually starts producing them, shows intellectual dishonesty, not a love for science. Be proud that we are witnessing the renaissance of Bhartiya knowledge. It is a long journey, but Satya always outlasts ideological noise.

The territorial principle – jus soli, citizenship by place of birth – governed, and it governed without qualification. That legal certainty no longer exists. India has, through two Parliamentary amendments, progressively dismantled unconditional birthright citizenship. A child born in India today does not automatically acquire Indian citizenship. The position now depends entirely on parental status at the time of birth – and the conditions are strict.

Lee Kuan Yew: “Air conditioning was a most important invention for us, perhaps one of the signal inventions of history. It changed the nature of civilization by making development possible in the tropics. Without air conditioning you can work only in the cool early-morning hours or at dusk. The first thing I did upon becoming prime minister was to install air conditioners in buildings where the civil service worked. This was key to public efficiency."
