Mushroom on Mars? Blog post claims to spot a sign of life on red planet

Mint19-06-2025
A decade-old image from NASA's Mars rover Curiosity has resurfaced online, reigniting speculation about the possibility of life on the Red Planet. The photograph, originally taken on September 19, 2013, recently caught the attention of UFO enthusiast Scott Waring, who claims it features an object resembling a mushroom.
Waring, a self-proclaimed UFO hunter known for his blog on extraterrestrial phenomena, said he discovered the unusual formation while reviewing archived Mars images on NASA's website. Highlighting a small protrusion near the centre-bottom of the image, he suggested it closely resembles a mushroom with a curved stem and wrinkled cap, similar to those found on Earth. His claims have since gone viral on social media, fuelling renewed debate over the existence of alien life.
The image was captured by the Mars Hand Lens Imager (MAHLI), a camera attached to the rover's robotic arm that provides high-resolution images of Martian rocks and soil.
In a blog post, Waring criticised NASA for allegedly ignoring the object. 'NASA should have poked it, bumped it, knocked it over, or cut it open using their onboard tools—or even used their laser to investigate,' he wrote.
However, scientific experts have been quick to refute the claim. Dr Gareth Dorrian, a planetary scientist at the University of Birmingham, told the Daily Mail that the object is more likely a naturally occurring rock formation. According to him, what appears to be a mushroom is probably a disc-shaped rock that may have been exposed over time as wind eroded the surrounding sand and dust.
While the object may not provide definitive evidence of life, the resurfaced image has revived public curiosity around one of space science's biggest unanswered questions: Is there—or was there ever—life on Mars?
NASA's Curiosity rover, which has been operating on the Martian surface since 2012, has found promising clues over the years. It has detected organic molecules in Martian rocks and methane in the atmosphere, both considered potential indicators of microbial life. Yet, no conclusive evidence has emerged so far.
With multiple international missions planned in the coming years, including Mars sample-return projects, scientists continue to explore the Red Planet's past and present habitability. The viral mushroom-like rock may not offer the answers, but it's a reminder of just how invested humanity remains in unlocking Mars' many mysteries.

Future of farming? How astronauts are growing food in space

In a discussion with PM Narendra Modi, Indian astronaut Group Captain Shubhanshu Shukla highlighted the importance of food in space missions and spoke of how he grew methi and moong seeds while being on the International Space Station. But why is space farming becoming an important aspect of space exploration? Following his successful mission to the International Space Station (ISS), making him only the second Indian in space, Group Captain Shubhanshu Shukla is back on Earth and has returned to India. On Monday evening, the Indian astronaut met with Prime Minister Narendra Modi at the latter's residence, 7 Lok Kalyan Marg, discussing the success of the Axiom-4 mission, as well as India's ambitious Gaganyaan mission. During the interaction, Shukla spoke about his many experiments aboard the ISS, including growing crops in space. For those who aren't aware, Shukla turned farmer in space — growing 'moong' and 'methi' seeds in petri dishes aboard the ISS. Speaking on the same to Modi, Shukla said that food remains a major challenge aboard space stations due to limited space and expensive cargo. He further noted the potential of his experiments to address food security challenges — not only for astronauts but also for vulnerable populations on Earth. STORY CONTINUES BELOW THIS AD A wonderful conversation with Shubhanshu Shukla. Do watch! @gagan_shux — Narendra Modi (@narendramodi) August 19, 2025 This got us wondering — how do plants grow in space? And why is it important for space travel? Shukla turns space farmer As part of his now successful Axiom-4 mission, Shukla conducted various experiments in space, including growing plants on board the ISS. In fact, this was the most crucial of his seven experiments. Indian astronaut Shubhanshu Shukla aboard the International Space Station planting moong and methi seeds. File image/PTI As part of the mission, he planted moong and methi seeds in petri dishes and kept them in a storage freezer. This activity was part of a study into the influence of microgravity on germination and early plant development. These seeds will be cultivated over multiple generations after their return to earth, with researchers looking into changes in their genetics, microbial ecosystems and nutritional profiles. Recalling this experiment, he told PM Modi in Monday's discussion, 'Food is a big challenge on space station. Many experiments are ongoing to grow food in space. We did micro-gravity research — it could solve food security problems on earth too.' Growing food in space But Shukla isn't the first astronaut to try his hand at farming on board the ISS. Astronauts have been growing plants in space on a fairly small scale. In fact, in 2014, Nasa, America's space agency, launched the Vegetable Production System, known as Veggie, on board the ISS. Simply put, it is a space garden, which is the size of an average carry-on bag. It typically holds six plants. The purpose of Veggie is to help Nasa study plant growth in microgravity, while adding fresh food to the astronauts' diet and enhancing happiness and well-being on the orbiting laboratory. Mixed greens (mizuna, red romaine lettuce and tokyo bekana cabbage), grown in Nasa's Veggie facilities. File image/AFP To date, Veggie has successfully grown a variety of plants, including three types of lettuce, Chinese cabbage, mizuna mustard, red Russian kale and zinnia flowers. So far, some of the plants have been harvested and eaten by the crew members, while remaining samples have returned to earth to be analyeed. One concern was harmful microbes growing on the produce. So far, no harmful contamination has been detected, and the food has been safe (and enjoyable) for the crew to eat. STORY CONTINUES BELOW THIS AD But how are these plants grown? There are two ways: one is through hydroponics — the method of growing plants without soil, using nutrient-rich water solutions — and the second being through aeroponics, which eliminates the need for soil or any other medium. Plants can also be grown in space in soil-like media. International Space Station astronauts Mark Vande Hei, Shane Kimbrough, Akihiko Hoshide and Megan McArthur, pose with peppers grown in space for the first time aboard the orbiting laboratory platform for the Plant Habitat-04 investigation. File image/Reuters In Nasa's Veggie garden, the plants are grown in a 'pillow' filled with a clay-based growth media and fertiliser. The pillows are important to help distribute water, nutrients and air in a healthy balance around the roots. Earlier, this year, even Isro made strides in space farming with the CROPS box, which is like a mini-greenhouse. It is an experimental module designed to develop Isro's capabilities for growing and sustaining plants in space. It has a soil-like medium, water, sunlight-mimicking lights, and Earth-like air. Challenges in growing food in space However, growing plants in space is no child's play and goes beyond just having a green thumb. Firstly, astronauts have to contend with microgravity. In a zero-gravity environment, plants struggle to orient themselves properly, as their natural response to gravity doesn't function the same way. Essentially, the plant doesn't have the same instinct for the roots to grow downwards and the stems to grow upwards, which can affect development and nutrient absorption. STORY CONTINUES BELOW THIS AD There are multiple challenges to farming in space, namely the issue of zero gravity and the lack of soil or natural light. Representational image/AI-generated There's also the issue of having less space and no natural light. On earth, plants have access to loads of natural sunlight. However, this doesn't apply to space. For this reason, artificial light has to be provided, but that too is difficult owing to the importance attached to using energy efficiently. Energy can't be wasted on light bulbs. In addition, different types of lighting create different levels of heat, and extra heat is something spacecraft must eliminate. Additionally, astronauts don't have extra room to lug spare light bulbs through space, so they need a lighting source with staying power, like light emitting diodes (LEDs). The confined quarters of the ISS is another challenge that astronauts have to deal with. Besides these challenges, there's also the problem of radiation and contamination. There's a chance that the plants grown in space be contaminated with organisms from space, making them inedible for humans. Changes in their genetic codes could be harmful in other ways. As How Stuff Works notes, we could land up with a space version of kudzu — an invasive species of plant brought to the US from Japan in the late 1800s. STORY CONTINUES BELOW THIS AD Importance of space farming But what purpose does growing plants in space serve? The main benefit of growing plants in space is to enable long-term space exploration — we are eyeing longer space missions and even colonising Mars. For this, it is critical that astronauts have a regenerative source of food. After all, imagine going on vacation for a year and having to pack all the meals you planned on eating — your bags would only be stuffed with groceries. Plants could also assist the life support system in other ways too. They can be used to purify water and recycle carbon dioxide into oxygen. If grown on a large-enough scale, plants could hugely impact how spacecraft and colonies are designed. As humans seek to further explore space and even colonise Mars, they will need a regenerative source of food. Representational image/AI-generated As Siddharth Pandey, an affiliate research scientist with US-based Blue Marble Space Institute of Science, told The Indian Express, 'Since plants release oxygen during photosynthesis, growing them in space can help keep the air aboard spacecraft breathable. Plants can recycle carbon dioxide and organic waste, creating a closed-loop life support system.' STORY CONTINUES BELOW THIS AD Space farming can also benefit humans on Earth. Scientists hope to transfer the knowledge they gain from growing plants in the inhospitable climate of space to hostile climates on earth. This will help as land becomes scarcer and less fertile. It seems that while we are far, far away from a salad bar in space, we are making giant leaps in space farming. With inputs from agencies

"Allow Parliament To Felicitate" Shubhanshu Shukla: Kiren Rijiju To Opposition

New Delhi: Union Parliamentary Affairs Minister Kiren Rijiju on Tuesday appealed to Opposition parties to allow Parliament to felicitate Axiom-4 Mission Pilot and IAF Group Captain Shubhanshu Shukla, along with Indian scientists, for the country's recent success in space exploration. In a post on X, Kiren Rijiju wrote, "I again.. appeal to opposition parties to allow Parliament to felicitate Capt Subhanshu Shukla and the entire Indian Scientists for India's remarkable and successful space mission. All our heroes deserve appreciation!" I again.. appeal to opposition parties to allow Parliament to felicitate Capt Subhanshu Shukla and entire Indian Scientists for India's remarkable and successful space mission???? All our heroes deserve appreciation! — Kiren Rijiju (@KirenRijiju) August 19, 2025 His remarks came after the Opposition created an uproar during a special discussion in Parliament on India's space programme and the successful International Space Station (ISS) mission of Group Captain Shubhanshu Shukla. The discussion, titled "India's Space Program and Its Role in Viksit Bharat 2047", was aimed at highlighting the nation's scientific progress, national pride, and future security prospects. The opposition members disrupted the session by shouting slogans, demanding a discussion on the Special Intensive Revision (SIR) of the voter list in Bihar. Earlier, on Monday, Union Minister of State (Independent Charge) for Science and Technology, Jitendra Singh, hit out at the Opposition parties, calling it "surprising" that the opposition cannot even praise the country's achievements in space. "The opposition has failed to congratulate the space experts and scientists for our space achievements. Your anger can be with the government. Your anger can be with the BJP and the NDA. But it is surprising that you can be angry with an astronaut. And that astronaut who, apart from being an astronaut, is also a disciplined soldier of the Indian Air Force. He does not belong to any political party," Jitendra Singh said in Lok Sabha amid sloganeering by the opposition MPs. Mr Shukla, who returned to Earth on July 15 after completing NASA's Axiom-4 (AX-4) space mission, landed in the national capital in the early hours of Sunday. Mr Shukla was part of NASA's Axiom-4 Space Mission, which took off from NASA's Kennedy Space Centre in Florida, US, on June 25. He returned to Earth on July 15, splashing down off the coast of California. He became the first Indian in 41 years to travel to space.

NASA alert! Stadium-sized asteroid 1997 QK1 set for close flyby of Earth on August 20 at 22,000 mph; here's what you need to know

Asteroids have long fascinated scientists and the public alike, serving as reminders of both the beauty and unpredictability of our universe. These rocky remnants from the solar system's formation often pass through Earth's neighborhood, sometimes sparking excitement and curiosity when they come unusually close. While most of these flybys are harmless, they provide valuable opportunities for researchers to study asteroid behavior, refine orbital models, and improve planetary defense systems. NASA , along with other global space agencies, closely monitors such events to ensure Earth's safety and to expand our understanding of near-Earth objects. One such asteroid making headlines now is 1997 QK1, a massive space rock expected to pass Earth on August 20, 2025, during a safe but significant flyby. NASA confirms asteroid 1997 QK1 will pass Earth on August 20: Size and distance Asteroid 1997 QK1 was first detected in the late 1990s and has been tracked ever since. It belongs to the Aten group of near-Earth asteroids, named after the Egyptian sun god Aten. These asteroids are unique because their orbits cross Earth's path around the Sun, making them frequent candidates for close encounters. This asteroid's large size makes it particularly notable. To put its dimensions into perspective: It is longer than three football fields lined up. If it ever struck Earth, it could cause regional devastation, though not global extinction like the asteroid linked to the dinosaurs' demise. Fortunately, its trajectory ensures it will remain safely distant during this flyby. On August 20, the asteroid will pass within 1.87 million miles (3 million kilometers) of Earth. While this may sound vast, in astronomical terms it qualifies as a close approach. For comparison: The Moon orbits Earth at about 238,855 miles (384,400 km). This asteroid will pass roughly eight times farther than the Moon's distance. Though distant in human terms, space agencies classify such encounters as significant because they allow researchers to refine orbital predictions and study asteroid behavior more closely. Why Asteroid 1997 QK1 is not a threat Asteroids are classified as Potentially Hazardous Objects (PHOs) if they meet two conditions: They are larger than 140 meters (460 feet). They come within 4.6 million miles (7.4 million km) of Earth. Asteroid 1997 QK1 meets both criteria, but 'potentially hazardous' does not mean 'imminently dangerous.' Instead, it signals that its path deserves careful tracking. NASA's precise calculations confirm that this flyby is safe, with no risk of impact now or in the near future. Why NASA and global space agencies track asteroids Asteroid monitoring is a cornerstone of planetary defense. Even small changes in an asteroid's orbit—caused by gravitational nudges from planets or effects like the Yarkovsky effect (when sunlight heats one side of an asteroid, slowly altering its trajectory)—can shift its long-term path. By observing asteroids like 1997 QK1, scientists aim to: Improve orbital models to predict future movements. Assess their composition, density, and spin rate. Explore strategies for deflection missions if a dangerous asteroid is discovered in the future. Notably, NASA's DART mission (Double Asteroid Redirection Test) in 2022 demonstrated the possibility of altering an asteroid's orbit by deliberately crashing a spacecraft into it—an important milestone in planetary defense. India's ISRO plans future missions to study near-Earth asteroids The interest in asteroids is not limited to NASA. The Indian Space Research Organisation (ISRO) has outlined plans for participation in global asteroid studies. According to ISRO Chairman S. Somanath, future missions may include research on larger near-Earth objects, especially as the world prepares for the highly anticipated close approach of asteroid Apophis in 2029. International collaborations involving NASA, ESA (European Space Agency), and JAXA (Japan) are essential, as planetary defense requires shared data and joint strategies. By pooling resources and expertise, space agencies ensure Earth is better prepared for cosmic encounters. Why asteroid 1997 QK1's flyby is a scientific opportunity for NASA and ISRO The flyby of 1997 QK1 is more than a cosmic spectacle—it is a scientific opportunity. Studying such objects helps researchers uncover: Clues about the solar system's formation, since asteroids are primitive building blocks of planets. Insights into their structural integrity, important for future resource mining or deflection missions. Better risk assessment models, ensuring preparedness for genuine threats. Although harmless, this event underscores the importance of constant vigilance. The universe is filled with millions of space rocks, and only careful monitoring can separate harmless visitors from those that could alter life on Earth.
