From space on Earth to the Earth: Indian astronauts finish 10-day Mars simulation in Ladakh
Space missions help us explore the unknown, pushing the limits of human knowledge and technology. They prepare astronauts for the challenges of living and working beyond Earth, paving the way for exciting journeys to the Moon, Mars, and beyond.
Each mission brings us closer to new heights, but what if these missions are simulated on the Earth itself?

10-day Mars analog mission
in Ladakh
Two Indian astronauts, Rahul Mogalapalli and Yaman Akot, recently completed a 10-day analog mission inside the Hope habitat located in the rugged Tso Kar region of Ladakh, about 150 km from Leh. The mission simulated the extreme conditions and routines astronauts would face during lunar and Martian exploration, providing a realistic and challenging training environment.
Speaking to IndiaToday, Rahul described the experience as 'a real learning curve.' He explained, 'We had to ration food, water, and even internet bandwidth. Maintaining communication and staying disciplined was tough, but if given a chance, I'd do it again.' Both Rahul and Yaman also talked about the psychological challenges posed by extended isolation, emphasising the importance of such missions for India's future space exploration plans.

What is the Hope mission?
The Hope mission, officially known as the Himalayan Outpost for Planetary Exploration (HOPE), is India's first try at recreating what living in space might be like, right here on Earth. Created by Bengaluru-based Protoplanet in collaboration with
ISRO
's Human Space Flight Centre (HSFC), it uses two habitat modules named Phobos and Deimos, after Mars' moons, to copy the conditions astronauts would face on long space trips.
Located in Ladakh's harsh terrain, where temperatures swing significantly from 35°C to -25°C, the site gives conditions closely resembling those on Mars. The extreme weather and altitude make it an ideal location for testing the effects of isolation and limited resources.
Why is this mission important?
The data gathered during this mission is crucial for ISRO's upcoming
Gaganyaan mission
, which aims to send Indian astronauts into space by 2027 and eventually to the Moon by 2040.
Rahul and Yaman conducted several biomedical experiments, including collecting urine, breath, and blood samples. These will be analyzed by ISRO scientists to understand the physiological, genetic, and psychological impacts of isolation and the harsh environment.
According to India Today, Dr. Siddharth Pandey, founder and director of Protoplanet, highlighted the mission's value not just for the astronauts but also for the entire team involved in preparing India's space future.
He shared plans to expand the habitat to accommodate up to six analog astronauts and hopes that future Gaganyaan astronauts will take part in such simulations.
According to the information from protoplanet and ISRO's Human Space Flight Centre, following this successful mission, the Phobos and Deimos, simulator modules will function as automated weather stations, gathering data for upcoming missions. Protoplanet is already preparing for the next simulation, expected in April 2026.
By successfully completing this analog mission, India takes a giant leap forward in preparing its astronauts for the challenges of space travel beyond Earth. The HOPE mission serves as a vital rehearsal, bringing the country closer to realizing its dream of establishing a human presence on the Moon and, eventually, Mars.

Meet the Only Indian Actor in Alien: Earth Who Worked at Tea Stall, Sang with Ilaiyaraaja and is Now Making Waves in Hollywood
Adarsh Gourav is the only Indian actor in Alien: Earth, now streaming on Disney+ Hotstar in India (August 13) after its U.S. debut on Hulu and FX (August 12). He plays 'Slightly,' a synthetic child navigating a dark, dystopian future, an emotionally layered role that critics are already praising. The performance marks a major milestone for the Jamshedpur-born actor-singer and places an Indian talent at the heart of the iconic Alien franchise. From Jamshedpur to the Alien universe Born in July 1994, Gourav grew up in Jamshedpur before moving to Mumbai at 13. He studied at Loyola School, Lilavatibai Podar, and Narsee Monjee College. His early life was rooted in music: nine years of Hindustani classical training, tabla lessons, and fronting indie bands like Steepsky and Oak Island. He performed on MTV Indies and recorded songs, jingles, and ads, building a music-first résumé long before mainstream stardom. Here's how he got his start in front of the camera At Ajivasan (Suresh Wadkar's academy), Padma Wadkar mentored Gourav and gave him multiple stage opportunities across Mumbai. During a 2007 Mumbai festival performance of Vande Mataram, he was noticed by Nazali Karamyoi of Raell Padamsee's company Ace, which led to acting auditions. According to The Times of India, in 2010, he made his screen debut in My Name Is Khan, playing the younger version of Shah Rukh Khan's character, a high-profile first role for a teenager. Music roots with Ilaiyaraaja and Sukhwinder Singh Before acting took center stage, Gourav shared platforms with Ilaiyaraaja and Sukhwinder Singh in 2007-08. He continued to record for films and campaigns, keeping his classical base while exploring contemporary styles. Those stage hours and studio sessions inform the vocal control and emotional precision visible in his screen work today. The White Tiger breakthrough and method grit After training at The Drama School Mumbai (on advice to pursue acting seriously), Gourav worked steadily in Mom, Rukh, Madly, Leila, and Die Trying. His breakout came with The White Tiger (2021). As Balram Halwai, he earned BAFTA and Independent Spirit Award nominations. For realism, he worked at a tea stall during prep. Post-White Tiger, Gourav appeared internationally (including Explorations with Meryl Streep and Kit Harington) and at home in Hostel Daze, Guns & Gulaabs, and Kho Gaye Hum Kahan. With Alien: Earth on Disney+ Hotstar in India and Hulu/FX in the U.S., his portrayal of Slightly positions him as one of the most compelling South Asian actors in the global sci-fi genre.

Galaxies flying away from us: How Hubble's redshift led us to the Big Bang
On a crisp night in the late 1920s, Edwin Hubble stood in the dome of the 100-inch Hooker telescope at Mount Wilson Observatory, high above the smog and streetlamps of Los Angeles. Through that giant eye, he measured the light from distant 'spiral nebulae' — what we now call galaxies — and found something remarkable. Their light was shifted toward the red end of the spectrum, a sign that they were racing away from us. It was as if the universe itself were stretching. When light from a moving source is stretched to longer wavelengths, we call it redshift — much like the way a passing train's whistle drops in pitch as it moves away. Hubble discovered that the farther a galaxy was, the greater its redshift — meaning the faster it was receding. This became the Hubble–Lemaître law, a simple but revolutionary equation showing that the universe is expanding. But here's the subtlety: the galaxies are not flying through space as bullets through the air. Instead, the space between them is stretching. A common analogy is raisin bread dough rising in the oven — as the dough expands, every raisin moves away from every other raisin, and the farther apart two raisins start, the faster they separate. Crucially, the bread isn't expanding into the kitchen; the dough itself is the 'space.' In the same way, the universe isn't expanding into some empty void — it's the distance scale itself that's growing. This is why galaxies farther away show greater redshift: they're not just distant in space, they're distant in time, and the intervening space has been stretching for billions of years. The implication was staggering: if the galaxies are all moving apart today, then in the distant past, they must have been much closer together. Follow this logic far enough back and you arrive at a moment when all the matter, energy, space, and time we know were compressed into a single, unimaginably dense point. The first to put this into words was Georges Lemaître, a Belgian priest and physicist. In 1931, he proposed that the universe began from a 'primeval atom' — an idea that would later be nicknamed the Big Bang. At the time, the name was meant to be dismissive; British astronomer Fred Hoyle, along with his student and celebrated Indian astrophysicist Jayant Narlikar, champions of the rival Steady State theory, coined it in a radio broadcast to mock the idea of a cosmic explosion. Ironically, the label stuck and became the most famous phrase in cosmology. For decades, the debate raged: was the universe eternal and unchanging, or did it have a beginning? The tie was broken not in an ivory tower, but in a New Jersey field. In 1964, Arno Penzias and Robert Wilson, two engineers at Bell Labs, were testing a radio antenna for satellite communications when they picked up a persistent hiss of microwave noise. They cleaned the antenna, even shooed away nesting pigeons — but the signal stayed. Unbeknownst to them, just 50 km away, Princeton physicist Robert Dicke and his team were preparing to search for the faint afterglow of the Big Bang. When the groups connected, the truth emerged: Penzias and Wilson had stumbled upon the cosmic microwave background (CMB), the fossil light from the universe's infancy, released about 380,000 years after the Big Bang. The CMB confirmed that the universe had indeed begun in a hot, dense state and has been cooling and expanding ever since. In the first fraction of a second, an incredible burst of inflation stretched space faster than the speed of light. This expansion wasn't into anything — rather, the very fabric of space itself was stretching, carrying galaxies along with it. As space grows, so does the distance scale we use to measure it: a galaxy whose light left billions of years ago was much closer then than it is today. That's why the farther away we look, the greater the redshift we see — we are peering not just across space, but back in time, to when the universe was smaller. The CMB is the afterglow from a time about 380,000 years after the Big Bang, when the universe had cooled enough for electrons and protons to form neutral atoms, letting light travel freely for the first time. That light has been on a 13.8-billion-year journey to us, its wavelength stretched by cosmic expansion from the fierce glare of the early universe into the faint microwave glow we detect today. Over the next minutes after the Big Bang, nuclear fusion forged the first elements: hydrogen, helium, and traces of lithium. Hundreds of millions of years later, the first stars and galaxies ignited, manufacturing heavier elements in their cores and seeding the cosmos with the building blocks of planets and life. Billions of years on, our Sun and Earth formed from recycled stardust, and here we are — creatures of carbon, contemplating the birth of time. The Big Bang theory is not just an origin story; it's a framework that explains everything from the cosmic web of galaxies to the faintest ripples in the CMB. It predicts the abundance of light elements, the distribution of galaxies, and the universe's large-scale geometry. Without it, we'd have no coherent picture of cosmic history. Today, the expansion first seen by Hubble is still ongoing — in fact, it's accelerating, driven by the mysterious dark energy. The latest measurements from telescopes like Hubble's successor, the James Webb Space Telescope, and surveys like the Sloan Digital Sky Survey continue to refine our understanding of the early universe, probing the first galaxies that emerged from cosmic darkness. The journey from a lone astronomer squinting at galaxies to a global scientific collaboration mapping the cosmos is a reminder that big ideas often start with small clues. As Carl Sagan once put it, 'We are a way for the cosmos to know itself.' The Big Bang is not just about how the universe began — it's about how we began, too. Shravan Hanasoge is an astrophysicist at the Tata Institute of Fundamental Research.

Man suffers rare bromism following ChatGPT diet tips. All about dangerous condition and its symptoms
A case of bromism has come to light after a man developed this rare condition following an interaction with ChatGPT about removing table salt from his diet. An article in the Annals of Internal Medicine reported a case in which a 60-year-old man developed bromism, also known as bromide toxicity , after consulting Chatgpt, according to Guardian. The article described bromism as "ingestion of bromide can lead to a toxidrome known as bromism. "While this condition is less common than it was in the early 20th century, it remains important to describe the associated symptoms and risks, because bromide-containing substances have become more readily available on the internet," it read.

Comedian startling relocation hint shocks fans What is bromism? The man told doctors that after reading about the negative effects of sodium chloride, or table salt, he consulted ChatGPT about eliminating chloride from his diet and started taking sodium bromide over a three-month period. This was despite reading that 'chloride can be swapped with bromide, though likely for other purposes, such as cleaning'. Sodium bromide was used as a sedative in the early 20th century. On admission, the patient shared that he maintained multiple dietary restrictions and that he distilled his own water at home. He was noted to be very thirsty but paranoid about water he was offered. Live Events According to the journal, Bromide toxicity, or bromism, was once a well-recognized toxidrome in the early 20th century that precipitated a range of presentations involving neuropsychiatric and dermatologic symptoms. Bromism was thought to have contributed to up to 8% of psychiatric admissions at that time, as bromide salts were found in many over-the-counter medications targeting a wide array of indications, including insomnia, hysteria, and anxiety. ALSO READ: DOGE price forms golden cross for the first time since Nov 2024. Could a massive 300% surge be next? "The incidence of bromism declined dramatically when the U.S. Food and Drug Administration eliminated the use of bromide between 1975 and 1989 (3). However, case reports of bromism have reemerged within recent years, including from dietary supplements, bromide-containing sedatives, and excess dextromethorphan. While cases of bromism may remain relatively rare, it remains prudent to highlight bromism as a reversible cause of new-onset psychiatric, neurologic, and dermatologic symptoms, as bromide-containing substances have become more readily available with widespread use of the internet," according to the journal. Bromism was diagnosed as the lab results of the patient were weird and his blood shows what looks like high chloride levels. ALSO READ: Seven simple brain exercises to lower your dementia risk What is bromide intoxication and what are its symptoms? Bromide intoxication happens when too much bromide — a chemical element related to chlorine — builds up in your body. You won't find bromide normally in your everyday food items but it can still get into your system from certain medications, supplements, or imported products. What's the problem with bromide? Your body doesn't get rid of bromide super quickly. It competes with chloride (yes, like in table salt) for space in your cells. When bromide sticks around, it starts messing with your nervous system. The symptoms of bromism headaches, confusion, memory problems, dizziness, slurred speech, tremors, and in severe cases, hallucinations or psychosis. Because the symptoms are vague, people sometimes go months without realizing bromide is the culprit.
