Ashoka Chakra to the Stars: A Deep Dive into Shubhanshu Shukla’s Night Vision of India
A Republic Day Like No Other Today, January 26, 2026, marks a watershed moment in Indian history. As the nation celebrates its 77th Republic The Honorable President of India Smt. Droupadi Murmu has conferred the Ashoka Chakra—India's highest peacetime military decoration upon Group Captain Shubhanshu Shukla.
The Exclusive Unveil: India by Night During the recent Viksit Bharat Young Leaders Dialogue, Group Captain Shukla shared exclusive footage recorded from the Cupola—the ISS's seven-windowed observation deck.
It is important to note that this high-definition night-time footage of India was publicly unveiled for the first time by Group Captain Shubhanshu Shukla during this event. It has not been seen in previous ISRO mission updates, making this a rare glimpse into what our astronauts witness.

As the station traveled at 28,000 km/h from the Southwest to the Northeast of India, three stunning phenomena were captured. Here is the science behind what you are seeing.
1. The "Green Curvature": The Science of Airglow
In the video, a faint, neon-green arc hugs the curvature of the Earth. Shubhanshu identifies this as "Airglow," but what exactly is it?
The Chemistry: It is not an Aurora (which is caused by solar wind). Airglow is caused by Chemiluminescence. During the day, sunlight splits oxygen molecules in Earth's upper atmosphere apart.
The Recombination: At night, these atoms recombine, releasing their stored energy as photons of light.
The Significance: This green line marks the Kármán line and the upper boundary of our atmosphere. It is a visual reminder of the thin, fragile shield that protects all life on Earth from the vacuum of space.
2. The "Purple Flashes": Transient Luminous Events
Shubhanshu points out pulsating purple lights on the ground, identifying them as thunderstorms. However, viewing them from space offers a unique perspective unavailable on Earth.
Top-Down View: Astronauts see the storms from above, where the clouds act like a diffuser, turning sharp lightning bolts into soft, glowing "purple pools" of light.
Sprites and Elves: High-altitude pilots and astronauts often witness "Transient Luminous Events" (TLEs)—red or blue flashes that shoot upwards from thunderclouds into the ionosphere. The purple hue seen in the video is a signature of these high-energy atmospheric interactions.
3. The "Golden Web": The Economic Corridor
Perhaps the most striking visual is the human footprint. The video clearly shows the Bangalore-Hyderabad-Pune cluster.
The "Golden Triangle": The bright cluster of Bengaluru is unmistakable. But if you look closely, you can see thin, glowing arteries connecting it to Hyderabad and Pune.
Infrastructure from Space: These lines are the highways and industrial corridors that power India's IT and manufacturing economy. From 400 km up, political borders disappear, and you see only the interconnected "nervous system" of the nation's economy.
Conclusion: The Orbital Sunrise
The footage concludes with the ISS crossing the dark silhouette of the Himalayas. Suddenly, a blinding blue-white light pierces the frame.
This is an Orbital Sunrise. Because the ISS orbits Earth every 90 minutes, astronauts witness 16 sunrises and sunsets every day. The transition from pitch black to blinding daylight happens in mere seconds—a violent, beautiful reminder of our star's power.

If you enjoyed this deep dive into Shubhanshu Shukla's journey and the stunning views from the ISS, you will love the full story of how India reached this pinnacle of space technology.
I am proud to present my latest work, "Beyond Earth: The Indian Space Journey."
This narrative chronicles the remarkable trajectory of the Indian Space Research Organisation (ISRO)tracing the arc from transporting rocket components on bicycles to mastering the complexities of lunar landings. It is a testament to how vision, resilience, and indigenous technology have not only reached the stars but actively improved life for millions on Earth.
