NASA captures image of Mars' Arsia Mons volcano, nearly twice the height of Earth's tallest mountain
Image source: NASA Jet Propulsion Laboratory
NASA
has captured a breathtaking image of Arsia Mons, one of Mars' most massive volcanoes, towering nearly twice the height of any mountain on Earth. Captured at dawn by the 2001 Mars Odyssey orbiter, the photograph shows the volcano piercing through a layer of early morning haze, offering a surreal glimpse into the Martian horizon. Beyond its visual beauty, the image provides crucial scientific insights into Mars' volcanic past and atmospheric behaviour. Located in the Tharsis region, Arsia Mons' immense scale and persistent cloud cover make it a key subject for studying the Red Planet's evolving climate and geology.
NASA's Mars Odyssey captures stunning image of Arsia Mons volcano
NASA's Mars Odyssey spacecraft captured the breathtaking photo of Arsia Mons using its Thermal Emission Imaging System (THEMIS). The image is of the volcano above a green-colored haze of clouds passing over the Martian horizon at sunrise. The summit caldera of Arsia Mons is 120 kilometers wide, and it is larger than most volcanoes on Earth.
For comparison, Arsia Mons is approximately 20 kilometers high, roughly twice as tall as Mauna Loa in Hawaii, the tallest volcano on Earth and roughly 9 kilometers higher than the sea bed. "We were hoping to grab Arsia Mons rising above morning clouds—and it surely didn't disappoint," joined Arizona State University's THEMIS operations lead Jonathon Hill.
NASA studies Martian clouds and seasons using Arsia Mons observations
Arsia Mons is located in the Tharsis province of volcanoes on Mars, which has three colossal volcanoes. The southernmost and typically cloudiest of the three is Arsia Mons. Its thick cloud cover is most common at Mars' aphelion—the time when Mars is farthest from the Sun. The clouds play an important role in Martian climate observation and phenomena like the planet's notorious dust storms.
To record such seldom-observed horizon vistas, the Mars Odyssey orbiter performs a special 90-degree rotation maneuver so that its primarily ground-pointing camera may take pictures of the planet's atmospheric horizon. This special technique enables scientists to track dust and water-ice clouds and analyze their seasonal trends.
Planetary scientist Michael D. Smith at NASA's Goddard Space Flight Center commented,
"The horizon images exhibit large seasonal variations. These measurements are teaching us new things about how Mars' atmosphere varies with time."
Why Arsia Mons volcano image matters
In addition to its photographic attractiveness, the image of the Arsia Mons contains rich scientific information about Mars' geology and climate. Scientists gain a better understanding of predicting weather, dust storm formation, and the workings of larger-scale planetary phenomena by examining such volcanic formations and their interaction with the atmosphere.
This image is particularly important as the space agencies of the world hasten plans to send man to Mars and increase robotic missions to the Red Planet. Such images pave the way for more safe and informed voyages to the Red Planet and take man one step closer to discovering its mysteries.

Why NASA, ESA and others want to return to moon
AP image What you need to know: The prospect of humans returning to the moon looks more likely than ever, with NASA and ESA collaborating on the Artemis program There have been a number of recent, successful moon missions by China and India Space agencies and commercial companies want to use the moon for scientific research and as a base to get to Mars Growing interest in moon missions The Artemis program is a North American, NASA-led human spaceflight program, involving 55 international collaborators, including the European Space Agency (ESA). NASA aims to establish a permanent base at the moon's south pole and call it Artemis Base Camp. It also aims to launch a new space station, called Gateway, into the moon's orbit. Meanwhile, a joint China-Russia project involving 13 international partners aims to build a moon base called the International Lunar Research Station by 2035. Both the Artemis Base Camp and the International Lunar Research Station are proposed as scientific in nature. They will, if successful, host astronauts for short stays and house permanent robotic equipment, which could be operated from Earth. But the moon has also always been of strategic value. During the Cold War, the US and Soviet-era Russia fought out their ideological differences in space as well as on Earth. And so it is today, except there are more players. The US, for one, has stated publicly that it considers itself to be in a new space race, which it wants to win. Here are more reasons why: The moon is rich in resources Part of the moon's appeal lies in its abundant resources. These include: Iron Silicon Hydrogen Titanium Rare earth elements (REEs) While the costs of extraction and transportation are high, some of these resources could be brought back to Earth, where resources are dwindling in supply. Mining operations on the moon could pave the way for extracting an immense mineral wealth held in asteroids, and the moon will be the first place this will be tested. Most material extracted from the moon will be used to replace materials that would otherwise be needed to be brought from Earth, essentially making lunar bases self-sufficient. Regolith (lunar soil), for example, could be used as radiation protection and construction material for lunar bases. Water, which was first discovered on the moon in 2008 by the Indian mission Chandrayaan-1, will be important for drinking, growing food and cooling equipment. Missions since Chandrayaan-1 have shown there are high concentrations of ice at the poles, which is partly why the first lunar colonies are likely to be built there — and probably at the south pole, even though it is difficult to land there. These bases could also be used as "transit lounges" for astronauts on their way to Mars. For energy, solar radiation is already used to power some spacecraft and satellites, but regolith and water ice could also be used to make rocket propellant. The moon also contains significant amounts of helium-3, a potential fuel for nuclear fusion power. So, that's another reason future Mars missions are landing for a stopover on the moon as well as to refuel. Scientific research on the moon Scientific research is at the core of ESA's Moon Exploration Program, as it is for all space agencies, said Sara Pastor, ESA's lunar and gateway program manager, in an email to DW. Humans have had a continued presence in space for the past 20 years aboard the International Space Station. But the ISS is only 250 miles (about 400 kilometers) away in low Earth orbit, which is as little as four hours after launching from Earth. The moon is 250,000 miles away — about three days' spaceflight — and a far riskier journey for astronauts. The first research on the moon aims to make that journey safer and easier. Then there's environmental science: "[Scientists] will investigate the nature of lunar environments, how their unique conditions affect human health and performance, and robotic exploration systems, and how human activity affects these environments," said Pastor. Researchers will want to determine how water, metals and other lunar resources can be used to sustain lunar bases for the long term, and how best to extract them. "ESA is developing instruments for radiation environment measurements, drilling and in-situ sample analysis, geophysics and lunar space weather," said Pastor. Moon tech benefits us all on Earth It's often claimed that we owe mobile phones to the Apollo missions of the 1960s and '70s. While our mobile phones are not direct descendants from space tech, the Apollo missions did help miniaturise electronic and telecommunication devices. Dozens of modern technologies originally developed in the R&D labs of space agencies bring benefits to people on Earth — including home insulation, memory foam (used in mattresses), freeze-dried foods, robotic sensors and limbs and telemedicine. Scientists are developing medical equipment and health tracking methods to protect astronauts' health when they spend long periods in the extreme conditions of space, especially the human immune system. For example: portable, lightweight diagnostic equipment needed for spaceflight crews without medical training to monitor their health. These technologies could be used on Earth, too. From a lunar hub to a second (or third) home for humans on Mars? The long-term goal of building surface and orbital moon bases is so they can serve as a staging post for more distant space travel. "A colony on the moon will be extremely useful and a key training ground for Mars surface human exploration," said Pastor. NASA plans to send astronauts to Mars in the 2030s.

UPSC Key: Axiom-4 mission, Project Cheetah, and Tardigrades
Important topics and their relevance in UPSC CSE exam for June 10, 2025. If you missed the June 9, 2025, UPSC CSE exam key from the Indian Express, read it here. Syllabus: Preliminary Examination: Current events of national and international importance Mains Examination: General Studies-III: Awareness in the fields of IT, Space, Computers, robotics, nano-technology, bio-technology and issues relating to intellectual property rights. What's the ongoing story: AS GROUP Captain Shubhanshu Shukla gets ready to become the first Indian to go to space in over 40 years, an 18-member team from the Indian Space Research Organisation (ISRO), led by chairman V Narayanan, has reached NASA's Kennedy Space Center in Florida to witness the launch of Axiom-4 mission, which has been postponed by a day due to weather conditions. It is now set for lift-off on Wednesday, 5.30 pm India time. Key Points to Ponder: • What is the Axiom-4 mission? • What is the significance of the International Space Station (ISS)? • What is the theme of the Axiom-4 mission? • What is the Gaganyaan mission? • What is India's roadmap for setting up the Bharatiya Antariksha Station? • How does the Indian space sector benefit from private-sector participation? • How is Shukla's experience going to help India in future space missions? • How is India planning to exploit the space market? • What is the NISAR mission? • What is the Artemis accord? Key Takeaways: • Shukla is the designated pilot for the Axiom-4 mission that will travel to the International Space Station (ISS) — after a journey of 28 hours in space. The mission's Crew Dragon spacecraft is scheduled to dock with ISS around 10 pm India time on Thursday. The transfer of astronauts, from the spacecraft to the ISS, could take another couple of hours after the docking. • Shukla is the first Indian to go to the ISS, a permanent space laboratory, that has been orbiting the Earth for the last 25 years, and is constantly manned by astronauts. He is only the second Indian to go to space, more than 40 years after Rakesh Sharma went on a Soviet mission in 1984. • Shukla's participation in the Axiom-4 mission has been facilitated by an agreement between ISRO and NASA. Axiom Space, a private US company, has been enabled by NASA to carry crewed missions to the ISS as part of the effort to encourage private sector participation in space transportation, to low-Earth orbits and the ISS. • Axiom-4 is carrying four astronauts who will spend two weeks at the ISS. Besides Shukla, there is an astronaut each from Poland and Hungary, countries that, like India, are returning to space travel after over four decades. This is the reason why the theme of the mission is 'Realize the Return.' • The fourth member, also the commander of the mission, is space travel veteran Peggy Whitson, who holds the record for spending the maximum number of days, 675, in space over multiple trips. • Shukla's flight comes months ahead of the scheduled launch of Gaganyaan mission, which is ISRO's maiden attempt at sending a crewed mission to the Moon. • India now has its own human spaceflight mission in the works — the rocket has been human rated, the crew escape systems and parachutes have been tested in various conditions, the astronauts have completed their training. India's first crewed mission is scheduled for 2027. And, the learnings from the Axiom-4 mission will feed into it. • Human spaceflight missions are extremely challenging, more so when you are doing it for the first time. They are maybe a couple of orders of magnitude more complex than uncrewed missions because of the safety protocols that have to be integrated. This is the challenge that ISRO faces with the Gaganyaan mission. • That is why Shukla's experience with the Axiom-4 mission is important. He will bring real-life exposure that can be utilised in Gaganyaan. Shukla is the designated pilot of the Axiom-4 mission. He will learn a lot and gain in many ways during this mission. • Also, Shukla will be the first Indian to go to the ISS. He will have an opportunity to see how the ISS functions and operates. ISRO's next big project, after Gaganyaan, is to build its own space station. That is a massive infrastructural endeavour. • Space is a costly endeavour, and the sector can benefit hugely from private-sector participation. It will also make the sector more vibrant, facilitate innovation, expedite technology development, and attract new, young talent. It can also boost economic growth. • Globally, the space market is worth about $500 billion, and is expected to double by the year 2030. India, despite being a major spacefaring nation, accounts for a just 2% share of this market. We have the ambition of increasing our share to at least 10% in the coming years. Do You Know: 'Realising the return'— how an Indian became part of Axiom-4 • In June 2023, during Prime Minister Narendra Modi's state visit to Washington, India and the US announced a decision to finalise a strategic framework for human spaceflight cooperation. It was also revealed that Indian and American space agencies, Indian Space Research Organisation (ISRO) and National Aeronautics and Space Administration (NASA), would mount a joint effort to enable an Indian astronaut to travel to the International Space Station (ISS) by 2024. • Only three nations — the US, Russia and China — have a human spaceflight programme of their own. Shubhanshu Shukla's flight, which came about on the back of the 2023 announcement, is thus being seen as another preparatory step ahead of the Gaganyaan mission. • Their space agencies have been working on a joint NISAR (NASA-ISRO Synthetic Aperture Radar) mission for over a decade now, enabling a closer-than-ever partnership. That mission is finally ready now, and likely to be launched in the next few weeks from Sriharikota, Andhra Pradesh. • This closer collaboration was formalised a couple of months after Modi's Washington visit in June 2023, when India signed the Artemis Accords, a US-devised set of principles for responsible behaviour and cooperation in space exploration, particularly in lunar and deep planetary missions. • Shortly after the Artemis Accords were signed, Axiom Space, a private US-based space company, invited India to participate in its mission to the ISS. Axiom Space has been the first and till now the only beneficiary of a NASA programme to enable private US industry to send commercial crewed missions to low-earth orbits and the ISS. • Axiom Space has sent three multinational missions to the ISS so far, each carrying four astronauts.

What's the ongoing story: Assam Chief Minister Himanta Biswa Sarma Monday announced in a special one-day session of the Assam Assembly that the state government has decided to bring a 1950 Act into action to 'push back' into Bangladesh anyone who District Collectors prima facie find to be foreigners — without going through the state's existing system of Foreigners Tribunals. Key Points to Ponder: • What is the role of the Foreigners Tribunals? • What are the constitutional provisions related to tribunals? • What are the criteria to declare someone a foreigner in India? • What is Section 6A of the Citizenship Act? • What is the Immigrants (Expulsion from Assam) Act, 1950? • Who is considered a citizen in India? • What are the constitutional provisions related to citizenship in India? • What are the issues around the National Register of Citizens (NRC)? Key Takeaways: • He said this will be implemented in addition to the ongoing 'pushbacks' of people who have been declared foreigners by the Foreigners Tribunals (FTs); around 330 such declared foreigners have been pushed into Bangladesh in the past couple of weeks. • Speaking in the Assembly, Sarma referred to the October 2024 judgment of the Supreme Court in which a majority of a five-member Constitutional Bench headed by then Chief Justice D Y Chandrachud had upheld the constitutional validity of Section 6A of the Citizenship Act, which makes March 24, 1971 the cut-off date for citizenship in Assam. • Under the existing system in the state, the identification and declaration of 'foreigners' is done through Foreigners Tribunals (FTs). • FTs are quasi-judicial bodies that determine whether a person presented before them — usually referred by the border police or listed as 'D-voters' in electoral rolls — is a 'foreigner' or an Indian citizen. Those declared foreigners by these tribunals have the option to appeal against the order by approaching the Gauahti High Court and the Supreme Court. • In the judgment, after upholding the validity of Section 6A, the court had issued a set of six directions, of which one was: 'The provisions of the Immigrants (Expulsion from Assam) Act, 1950 shall also be read into Section 6A and shall be effectively employed for the purpose of identification of illegal immigrants.' Do You Know: • The Foreigners' Tribunals are quasi-judicial bodies meant to 'furnish opinion on the question as to whether a person is or is not a foreigner within the meaning of Foreigners Act, 1946'. • In 1964, the Centre passed the Foreigners' (Tribunals) Order under provisions of Section 3 of the Act. The FTs get two kinds of cases: those against whom a 'reference' has been made by border police, and those whose names in the electoral rolls have a D (Doubtful) against them. • Section 9 of the Foreigners Act says that 'the onus of proving that such person is not a foreigner or is not a foreigner of such particular class or description, as the case may be, shall, not withstanding anything contained in the Indian Evidence Act, 1872, lie upon such person'. • Previously, under the Illegal Migrants (Determination by Tribunals) Act, 1983, the onus of proving one's nationality or otherwise lay on the complainant. In 2005 (Sarbananda Sonowal vs Union Of India), the Supreme Court struck down the IMDT Act and held that it 'has created the biggest hurdle and is the main impediment or barrier in the identification and deportation of illegal migrants'.

What's the ongoing story: Amid continuing criticism of various aspects of Project Cheetah, wildlife officials and field scientists from the National Tiger Conservation Authority (NTCA) have authored a paper seeking to counter what they termed 'persistent criticism' and 'sensationalised media narratives' against the project, and defended its progress. Key Points to Ponder • What is Project Cheetah? • Cheetah in India- Know in detail • What is the IUCN status of Cheetah? • Trans-continental translocation of Animals-know the Issues and Challenges • How was the Reintroduction of the cheetah in India executed? • What are the challenges of the Project Cheetah? • Cheetah Project Steering Committee—Know its role, vision and powers • What is the significance of the Project Cheetah? • What are the other similar projects of the Indian government? • Read about the National Tiger Conservation Authority (NTCA) and the Cheetah Project Steering Committee. • Map work (World)- Namibia, Botswana, and South Africa. • Map work (India)- Kuno Palpur National Park and Gandhi Sagar Wildlife Sanctuary. Key Takeaways: • The officials and scientists said some of the criticism against the project was 'rooted in ideological biases'. Published in Frontiers in Conservation Science journal, the paper said that cheetahs imported to India have adapted ecologically and that the project had demonstrated significant progress in 2.5 years. • It added that the project was on a promising trajectory, even as cheetah reintroduction was a 'gradual and risky process, with inevitable and adaptive learning'. NTCA's assistant veterinary officer Sanath Krishna Muliya is the paper's lead author, and Project Tiger head Gobind Sagar Bharadwaj is among the co-authors. • The paper delved into issues such as the project's scientific merits, 'misplaced concerns about cheetahs in captivity', 'misinformed ethical and justice concerns', and 'misconceptions about veterinary capabilities and field interventions.' • The government officials said in the paper that the cheetahs were held in 'soft-release bomas' or large enclosures, where they hunted locally available prey, and no prey was provided. They added that the soft-release practice was internationally recognised for carnivore reintroductions. • The government is also negotiating with the governments of Namibia, Botswana, and South Africa, for more cheetah translocations, the paper said. Do You Know: • Project Cheetah was launched in September 2022 and introduced African cheetahs into India from Namibia and South Africa. Initially, 20 cheetahs were imported from the two countries.

Key Points to Ponder: • What are tardigrades? • What makes tardigrades one of the most resilient life forms on Earth? • What is the Voyager Tardigrades experiment? • Why do scientists study these microscopic, eight-legged organisms? • What is the Axiom-4 mission? • Read the biological structure and habitat of tardigrades and how these features contribute to their adaptability and widespread distribution. Key Takeaways: • Tardigrades, also known as 'water bears', are robust aquatic animals that have been around for roughly 600 million years, 400 million years before dinosaurs walked the planet. They have survived all the five major mass extinction events to have taken place thus far, and scientists believe they could be around long after humanity has died out. • Typically about 0.5 mm long when fully grown, tardigrades have four pairs of legs, with 4-6 claws on each foot. They also have a specialised mouth which helps them suck nutrients from plant cells, algae, and other small invertebrates. • Tardigrades can be found almost everywhere — from the highest mountains to the deepest oceans. Their most common habitat, however, is the thin film of water found on mosses and lichens, which bestows upon these animals the moniker of 'moss piglets'. • Siddharth Pandey, an affiliate research scientist with US-based Blue Marble Space Institute of Science, told The Indian Express that tardigrades owe their incredible resilience to cryptobiosis, a state in which organisms bring their metabolism to a near-complete standstill in the face of adverse environmental conditions. Tardigrades can reduce their metabolism to less than 0.01% of normal, and drop their water levels by more than 95%, a state called anhydrobiosis. • Both anhydrobiosis and cryptobiosis result in the emergence of a durable shrunken state, called tun, in which tardigrades are able to withstand extreme conditions. • Also, these animals produce unique proteins such as cytoplasmic-abundant heat soluble (CAHS) proteins which are key to their resilience. • Scientists will take tardigrades to the ISS in a state of tun, before reviving them and examining the effects of space radiation and microgravity on their biological processes. • The primary objective of the experiment is to identify the genes that are responsible for making these animals resilient. In other words, scientists hope to pinpoint the specific molecular machinery that enables tardigrades' survival and DNA repair in space. • This will help scientists develop strategies to protect astronauts during long-duration space missions, and preserve biological materials for extended space travel. Do You Know: • Tardigrades were discovered in 1773 by German zoologist Johann August Ephraim Goeze, they have become a subject of intensive research in the past few decades. • This is because tardigrades are remarkably resilient creatures, known to survive in the harshest of conditions. Water bears have been known to withstand temperatures as low as minus 272.95 degrees Celsius or as high as 150 degrees Celsius; endure ultraviolet radiation of space and pressures of 40,000 kilopascals (equivalent to what can be experienced at a depth of 4 km under the ocean's surface); and live after being stored in a freezer for 30 years, according to a report by Front Line Genomics. • Tardigrades have been a part of space missions since 2007, when some 3,000 moss piglets hitched a ride to space aboard the European Space Agency's Foton-M3 mission.

Key Points to Ponder: • What is the share of renewable energy in the total energy production of India? • What are the geographical and economic challenges in utilizing the true potential of renewable energy? • What are the major initiatives taken by the government related to the adoption of renewable energy? • What are the Hybrid projects? • Understand the science behind the production of solar, wind, and tidal energy. • What are the power purchase agreements (PPAs)? • A key challenge facing the sector is the inability of the transmission infrastructure. Elaborate. Key Takeaways: • Investments in renewables are also expected to surge by 52 per cent from Rs 2.5 lakh crore to Rs 3.8 lakh crore in FY26 and FY27, largely on account of increasing share of hybrid projects that are more capital intensive, the ratings agency said. • Of the total 75 GW renewable capacity to be added over the next two financial years, around 37 per cent will come from hybrid and storage-linked projects, significantly larger than the 17 per cent share in FY24 and FY25. • Hybrid projects mix solar and wind capacities to support more consistent generation, while storage-linked projects use batteries and pumped hydro to save excess power generation for later use. • Crisil Ratings said investments in renewables were recorded at Rs 1.8 lakh crore in FY22 and FY23, which increased to Rs 2.5 lakh crore in the following two fiscals, and is expected to grow by half to Rs 3.8 lakh crore in FY26 and FY27. The surge in investments will partly be on account of rising share of hybrid and storage projects, which are more capital intensive. • A key challenge facing the sector is the inability of transmission infrastructure to keep pace with capacity addition. • Renewable projects are also facing difficulties in securing buyers through renewable energy implementing agencies (REIAs), with not enough states signing power purchase agreements (PPAs). Do You Know: • Renewable energy sources such as solar power, hydroelectric power, and wind power can be harnessed repeatedly without depleting natural resources, making them essential to a sustainable future. Therefore, expanding the scope and uses of renewable energy sources is critical to reducing the dependence on fossil fuels and combating climate change. 1. Solar Energy: Solar energy is harnessed from the sun's radiation. It can be transformed into electricity using solar panels (photovoltaic cells) or alternatively can be utilised to produce heat through solar thermal systems. 2. Wind Energy: It is generated by converting the kinetic energy of wind into electricity using wind turbines. 3. Hydropower: It is created by harnessing the kinetic energy of flowing water in rivers, dams, waterfalls, etc. It is one of the oldest and most widely used forms of renewable energy. 4. Biomass Energy: Biomass is produced from organic materials such as plant residues, animal waste, and wood. It can be heated or converted to liquid or gaseous fuels for consumption. 5. Geothermal Energy: This form of energy is derived from the Earth's internal heat. These can be naturally occurring hot water reservoirs or can be man-made. Occurring at various depths and varying temperatures below the earth's surface, these geothermal resources can be used for electricity generation and direct heating applications. 6. Tidal and Wave Energy: It harnesses the movement of ocean water to generate electricity. Tidal energy relies on the gravitational pull of the moon and the sun, whereas wave energy captures the energy of surface waves.

What's the ongoing story: India's imports of permanent magnets—many containing rare earth elements (REEs)—nearly doubled to 53,700 tonnes in 2024-25 (FY25) from around 28,700 tonnes the year before, according to official trade data. Key Points to Ponder: • What are permanent magnets? • What are rare earth magnets? Why is it called rare earth minerals? • Which country has the most rare earth deposits? • What is the difference between critical minerals and rare earth elements? • What effects does China's dominance over the processing of rare earth magnets have on global supply chains? • What are the rare earth minerals found in India? • What should India do to prepare for future shortages of strategic minerals such as rare earth elements? Key Takeaways: • The surge in imports, with 93 per cent coming from China, preceded Beijing's April 4 export restrictions on rare earth magnets, which have since disrupted production lines globally. In India, with just 2-3 weeks of REE magnet supply remaining, industry executives are expected to travel to China in a bid to ease the shortage, sources told The Indian Express. • China is the dominant supplier of permanent magnets in India, accounting for upwards of 90 per cent share. Imports from China increased by 95 per cent year-on-year to 50,000 tonnes in FY25. Permanent magnets, especially those made with REEs, are widely used in electric vehicle (EV) motors, wind turbines, aerospace, and defence. • In contrast to FY25, imports in the ongoing financial year are expected to be tempered, after China imposed export restrictions on rare earth magnets and related materials from April 4, as a direct response to US imposing tariffs. • In India, a supply crunch is in the making, especially for neodymium-iron-boron (NdFeB) magnets used in EV motors. Over the past month or so, Indian carmakers are learnt to have used up inventories and there is likely to be a shortage going forward. • Earlier, a senior executive from the Indian car industry told The Indian Express that importers are now required to give their Chinese suppliers an undertaking that the rare earth magnets procured from that country would only be used in vehicles and not for defence or military applications. • Currently, IREL (India) Ltd, a PSU under the Department of Atomic Energy, refines rare earth oxides from heavy metal ores, containing REEs like cerium, lanthanum, neodymium, and praseodymium. However, production is limited. Moreover, the processing of refining oxides into alloys—and then into magnets—is highly technical and virtually non-existent in India. • Figuring out the supply chain for rare earth ores is a key challenge, with players looking at importing ores from Sri Lanka, Mongolia, and Myanmar, sources said. Another challenge for domestic players would be to remain viable as China significantly cuts prices of rare earth magnets. • According to the US Geological Survey's January 2025 data, India held the world's third-largest rare earth reserves in 2024—estimated at 6.9 million tonnes— behind China (44 million tonnes) and Brazil (21 million tonnes). However, on the production front, India ranked seventh at 2,900 tonnes, well behind China (255,000 tonnes), Myanmar (43,000), the US (41,600), Australia, Nigeria, and Thailand. • In the January 2024 report, India ranked fifth in reserves. The latest revision reflects reduction in other countries' estimates—Vietnam's reserves were cut from 22 million tonnes to 3.5 million, and Russia's from 10 million to 3.8 million. Do You Know: • Rare Earth Elements (REEs) or Rare Earth Metals are a set of 17 chemical elements in the periodic table — the 15 lanthanides, plus scandium and yttrium, which tend to occur in the same ore deposits as the lanthanides, and have similar chemical properties. REEs are classified as light RE elements (LREE) and heavy RE elements (HREE). • The 17 Rare Earths are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y). • Some REEs are available in India — such as Lanthanum, Cerium, Neodymium, Praseodymium and Samarium, etc. Others such as Dysprosium, Terbium, and Europium, which are classified as HREEs, are not available in Indian deposits in extractable quantities. Hence, there is a dependence on countries such as China for HREEs, which is one of the leading producers of REEs, with an estimated 70 per cent share of the global production.

Close watch on weather at NASA's Florida spaceport ahead of Axiom-4 launch on Wednesday
SpaceX, NASA and Axiom Space are closely watching weather patterns at the Kennedy Space Centre in Florida where Indian astronaut Shubhanshu Shukla and three others look forward to their travel to the International Space Station (ISS), now scheduled for Wednesday. Addressing a pre-launch press conference, SpaceX Vice President William Gerstenmaier said engineers had fixed some snags in the Falcon-9 rocket that were discovered during the static fire test and had gone unnoticed during the post-flight refurbishment of boosters. The Axiom-4 commercial mission to the ISS had to be put off by a day to Wednesday evening due to inclement weather conditions in the flight path of the SpaceX rocket that would lift off from NASA's Kennedy Space Centre in Florida. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 3.5, 4.5 BHK Homes starting at ₹4.89 Cr.* Hero Homes Learn More Undo Gerstenmaier said engineers had discovered a locks leak that was previously seen on the booster during its entry on the last mission and was not fully repaired during the refurbishment. "We are continuing to troubleshoot that. We should get that completed today and we will have that back in configuration. We are installing a purge that will essentially mitigate the leak if it still continues... on the launch day," he said. Live Events Gerstenmaier said engineers also discovered an engine 5 thrust vector control problem and the components associated with that have already been changed. "We will be complete with all our work this (Tuesday) evening and we will be ready to support launch as early as Wednesday," he said. Indian Space Research Organisation ( ISRO ) Chairman V Narayanan said on Monday that due to weather conditions, the launch of the Axiom-4 mission for sending Indian Gaganyatri to the ISS was postponed from June 10 to June 11. "The targeted time of launch is 5:30 PM IST on 11th June 2025," Narayanan said in a post on X on Monday. Jimmy Tager, the Launch Weather Officer, 45th Weather Squadron of the US Space Force, said there was surface high pressure to the south east of central Florida, which typically produces south west flow across the area. "Now over the next couple of days, the surface high pressure is going to move further towards the north and that is going to switch our primary flow towards the south east. South east flow does tend to create some more isolated scattered showers to thundershowers in the morning time," he said. He added that even though the Probability of Violation (POV) was lower for the initial attempt (June 10), for the next attempt on Wednesday, the POV does increase to 20 per cent. "And as we get to Thursday (June 12), the backup opportunity POV increases a little bit more to about 25 per cent. So though it is on the lower end, it does look like there could be a possibility of isolated scattered thunderstorms near the area at the launch time," Tager said. "But for the ascent corridor, even though the winds are pretty strong right now, it does look like winds are going to be improving over the next couple of days. As we get to Wednesday, winds will be even better, and Thursday, even better than Wednesday," he added. Dana Weigel, Manager, International Space Station Programme, NASA, said that there are launch opportunities till June 30. She was responding to questions on the launch window for the Axiom-4 mission due to unfavourable weather conditions. "I think we will have the vehicle ready, the crews trained and the cargo loaded. I think we're ready from a hardware standpoint. It is just kind of waiting for the weather to get there. In terms of launch opportunities, we have launch opportunities all the way through June 30," Weigel said. She said the Russian cargo vehicle 'Progress' will undock from the ISS later and a new one will dock for which there would be a brief cut-off for other launches. "Then, we have a brief cut-off for high Solar Beta. Then we pick up again like in the middle of July. So, plenty of opportunities to fly the vehicle," Weigel said. The Axiom-4 (Ax-4) mission comprises Commander Peggy Whitson, pilot Shukla and specialists Tigor Kapu of Hungary and Slawosz Uznanski-Wisniewski of Poland. The 14-day mission will "realise the return" to human spaceflight for India, Poland, and Hungary.
