Yellow Crystals on the Red Planet: Curiosity Rover Gets Scientists Curious!

Published

on


NASA’s Curiosity Rover has once again made headlines, this time by uncovering bright yellow crystals on Mars, a discovery that’s causing quite a buzz in the scientific community. These yellow crystals, identified as elemental sulfur, were revealed when the rover inadvertently drove over a rock, splitting it open and exposing the hidden treasure within.

The Discovery

On May 30, 2024, while exploring the Gediz Vallis channel, Curiosity encountered a rock that, when cracked open, revealed something unprecedented: yellow sulfur crystals. This discovery is particularly exciting because, while sulfur-based minerals have been found on Mars before, this is the first time pure elemental sulfur has been observed on the planet​.

Elemental sulfur, on Earth, is typically associated with volcanic and hydrothermal processes. Its presence on Mars adds a new layer to our understanding of the planet’s geological history. Scientists are now investigating the exact processes that might have led to the formation of these sulfur crystals on Mars. The discovery was made using Curiosity’s Mast Camera (Mastcam), which captured detailed images of the crystals​.

Geological Significance

This find is not just a geological curiosity but a significant clue in the ongoing exploration of Mars’s past. Sulfur minerals often form in water-rich environments, and their presence could indicate past hydrothermal activity on Mars. This further supports the hypothesis that Mars had a more dynamic and possibly habitable environment in its distant past​.

The Gediz Vallis channel, where the crystals were found, has been a focal point for scientists studying Mars. The area shows evidence of ancient water flows and landslides, suggesting a history of significant geological activity. These yellow sulfur crystals add to the growing body of evidence that Mars had a more complex and active geological history than previously thought​.

The Rover’s Role

Curiosity, launched by NASA in 2011, has been a tireless explorer of the Martian surface, providing invaluable data that has transformed our understanding of the Red Planet. The rover’s suite of scientific instruments, including the powerful drill on its robotic arm, allows it to analyse rock samples in detail. This latest discovery is a testament to the rover’s capabilities and the importance of continued exploration.

As scientists continue to analyse the sulfur crystals and the surrounding area, they hope to uncover more about Mars’ geological past and its potential to have supported life. Each discovery by Curiosity brings us closer to answering fundamental questions about the Red Planet. The quest to understand Mars is far from over, and with each new find, our curiosity only grows.

In the spirit of exploration, let’s keep our eyes on the skies and our minds open to the wonders that Mars and the rest of our solar system have to offer. After all, when it comes to space exploration, the sky isn’t the limit—it’s just the beginning.

ED searches 19 premises of Amazon, Flipkart vendors in FEMA probe

Published

By


The Enforcement Directorate Thursday conducted searches against some of the “main vendors” operating on platforms of ecommerce giants Amazon and Flipkart as part of a foreign investment “violation” investigation, official sources said.

A total of 19 premises of these “preferred” vendors located in Delhi, Gurugram and Panchkula (Haryana), Hyderabad (Telangana), and Bengaluru (Karnataka) were covered as part of the action, the sources said.

It is learnt that the ED inspected documents and took copies of some from the premises of about six such vendors who were not named.

The sources said a probe has been initiated by the federal agency under the provisions of the Foreign Exchange Management Act (FEMA) after it received several complaints against the two large ecommerce companies, where it is alleged that they were “violating India’s FDI (foreign direct investment) rules by directly or indirectly influencing the sale price of goods or services and not providing level playing field for all the vendors”.

There was no immediate response from the two ecommerce companies.

Meanwhile, the Confederation of All India Traders (CAIT) welcomed the ED action.

“The CAIT, along with several other trade bodies, has been raising these issues for the past few years. I welcome the Enforcement Directorate’s actions as a step in the right direction,” CAIT Secretary General Praveen Khandelwal said in a statement.

He claimed that the Competition Commission of India (CCI) had also issued “penalty notices” to Amazon and Flipkart, and their “preferred” sellers, for “engaging” in anti-competitive practices that have adversely affected small traders and ‘kirana’ (grocery) stores.

It has been reported in the past that the CCI, which works to ensure fair business practices across sectors in the marketplace, is already looking into alleged anti-competitive ways of ecommerce companies.

The CAIT and mainline mobile retailers’ association AIMRA had also petitioned the CCI sometime back seeking immediate suspension of operations of Flipkart and Amazon as they alleged that the companies engaged in predatory pricing and were burning cash to offer heavy discounts on products.

These practices, in turn, are creating a grey market of mobile phones, causing losses to the exchequer “as players in the grey market evade taxes”, they had said.

Commerce and Industry Minister Piyush Goyal had recently flagged the same concerns as he had questioned Amazon’s announcement of a $1 billion investment in India, saying the US retailer was not doing any great service to the Indian economy but filling up for the losses it had suffered in the country.

He had said in August that their huge losses in India “smells of predatory pricing”, which is not good for the country as it impacts crores of small retailers.

Goyal said e-commerce companies were eating into the small retailers’ high-value, high-margin products that are the only items through which the mom-and-pop stores survive.

The minister had said that with the fast-growing online retailing in the country, “are we going to cause huge social disruption with this massive growth of ecommerce”.

Khandelwal said that the CAIT has urged the CCI and the ED to protect the businesses of small traders.

“In the new Bharat, led by Prime Minister Narendra Modi Ji, no one is above the law. I am hopeful that now the law will take its rightful course and protect the livelihoods of small shopkeepers.

“This government is committed to ensuring that no entity can harm the trading community. In response to multiple complaints filed by the trading community regarding FDI violations and the anti-competitive practices of quick-commerce companies such as Blinkit, Swiggy, and Zepto, we urge both the CCI and the ED to take swift action and prevent any further, irreparable damage to the businesses of small traders,” he said in the statement.

The Insurance Regulatory and Development Authority of India (Irdai) constituted an internal committee to review the Irdai (Regulatory Sandbox) Regulations.

Based on the recommendations of the committee, it has proposed amendments to the regulatory sandbox regulations and seeks comments from the public at large on the proposed amendments.

Issuing an exposure draft on regulatory sandbox regulations, Irdai said the amendment seeks adoption of principle based approach over rule based approach.

Sonal Kapoor, Global Chief Commercial Officer of Prodigy Finance, told YourStory that India is its core market and has the largest share of its funding.

According to the Prodigy Finance 2022 Impact Report, students reported that the company’s loan helped them to pursue their dream career (91%), achieve success in their personal life (83%), and at least double their salary (74%).
