NASA's Curiosity rover captured images of ‘coral' rock on Mars that signify water existed on the planet
Although it resembles a coral typically found at the bottom of the ocean, it was a piece of rock that a NASA spacecraft — Curiosity rover — recently discovered on Mars that was supposedly formed a billion years ago.

The small, approximately 1-inch-wide (2.5 centimeters) light colored, wind-eroded rock, as described by Live Science, was found in the Gale Crater, which is a large impact basin on Mars.
A colorless image taken by a telescopic camera captured the familiar-looking object. Although this discovery is an exciting one — it isn't the first of its kind to be found.

That same camera, also known as the Curiosity's Remote Micro Imager, has reportedly captured similar-looking objects in the past, signifying that the planet had a watery past.
This is because these objects formed 'billions of years ago when liquid water still existed on the Red Planet. Water carried dissolved minerals into rock cracks and later dried, leaving the hardened minerals behind,' as explained by NASA in a recent statement.
'This common process, seen extensively on Earth, has produced fantastic shapes on Mars, including a flower-shaped rock,' the statement continued.

These discoveries give hope that there might've been life on Mars after all.
NASA's Curiosity has been busy this summer. Back in June, it captured images of a geological structure — which have been nicknamed 'spiderwebs' due to their insect-like pattern of ridges.
Similarly to the coral rock, these 'spiderwebs' also indicate that Mars once had water on it that hardered.
'The images and data being collected are already raising new questions about how the Martian surface was changing billions of years ago,' NASA said in a previous statement.

'The Red Planet once had rivers, lakes, and possibly an ocean. Although scientists aren't sure why, its water eventually dried up and the planet transformed into the chilly desert it is today.'
'Remarkably, the boxwork patterns show that even in the midst of this drying, water was still present underground, creating changes seen today,' NASA said.
'Eons of sandblasting by Martian wind wore away the rock but not the minerals, revealing networks of resistant ridges within.'

Why space (yes, outer space) is a much bigger business opportunity than you think
Morgan Stanley projects the space economy will hit $1.8 trillion by 2035. Yet most companies still don't have a strategy for it. Last quarter alone, multiple space startups secured seven-figure funding rounds. NASA's Artemis program also hit a major milestone. This is a very real, trillion-dollar economy forming in real time, and the window to get in early is closing fast. Critically, space is the first truly infinite domain of commerce. Unlike Earth-based markets, it offers endless potential for new infrastructure, new services, and new economies to emerge. And while many are distracted by AI or supply chain chaos, the next massive growth platform is quietly taking shape above our heads. It's not just rockets and rich guys. It's agriculture, R&D, and your next competitor When most people think of space, they picture billionaires in zero gravity or cinematic sci-fi. But the reality is that it's becoming a critical infrastructure layer for future business, just as the internet did 30 years ago. The parallels are striking. In the early 1990s, many leaders saw the internet as a novelty. Today, it's the backbone of the global economy. Space is on the same path, but with even broader implications. From biotech to agriculture to cybersecurity, space is already critically transforming industries. Biotech companies like Redwire and Varda Space Industries are leveraging microgravity for drug development and bioprinting, enabling breakthroughs not possible in Earth-bound labs. Agriculture firms are using real-time satellite imagery to optimize water use, detect crop stress, and improve yield forecasting. Platforms like Planet Labs and Descartes Labs are making precision agriculture scalable and climate-resilient. Cybersecurity providers have also been looking beyond Earth for years, as satellite networks become part of critical infrastructure. Companies like SpiderOak are pioneering zero-trust security models for space assets. The market is heating up and capital is flowing in In 2023 investors poured $12.5 billion into space startups globally, despite broader tech market pullbacks. Startups focused on in-space manufacturing, small satellite constellations, and launch technologies are leading the charge. The Artemis program is unlocking new lunar and deep space opportunities, while commercial players like SpaceX and Rocket Lab are slashing launch costs. Public-private partnerships are expanding rapidly. The Department of Defense is investing in space-based logistics and mobility. NASA is funding space-based solar power and commercial space stations. Private equity firms are acquiring ground infrastructure and launch supply chains. The smart money is building and pivoting, quickly. Four ways to make space part of your growth strategy Meanwhile, too many companies and policymakers remain tethered to earthbound thinking. The point of tapping into this market isn't to become a 'space company.' Most companies won't build satellites or spacecraft. Instead, they'll find new ways to leverage the unique conditions and infrastructure of space to improve their products, services, and operations on Earth. Or they'll take existing products and services and find ways to adapt them for space. Here's how to ensure you're positioned to lead in this rapidly expanding trillion-dollar market: Start thinking like a space vertical. You don't have to build rockets to benefit from space, but you do need to understand how the industry works. Study space value chains and learn where your products, services, or capabilities might fit in. Even surprising players can break into the market. For example, a small watchmaker in Albuquerque was tapped to build components for space-bound hardware. This wasn't because they were in aerospace, but because they solved a unique precision problem. Tap into satellite-enabled insights to optimize operations. If you're not already, look into ways your business can uniquely leverage satellite data for actionable insights, whether it's tracking supply chain bottlenecks, improving precision in agriculture, or identifying untapped markets with geospatial analysis. Codevelop with space startups tackling niche challenges. Consider partnering with startups innovating in microgravity manufacturing, on-orbit servicing, or space-based energy solutions. Explore shared R&D that aligns with your industry's specific needs, like 3D-printed components or novel materials. T rain your teams on space-driven opportunities. Upskill your workforce by collaborating with universities or space-focused research institutions. Equip your employees to identify how advancements like quantum communications or hypersonic transport could create revenue streams in your sector. The cost of waiting? Irrelevance. It's time to adapt, innovate, and lead. The companies that embrace space as a critical business opportunity will not only future-proof themselves but also define the next chapter of economic history. Every major technological revolution has created winners and losers. Space will be no different.

Space Race 2.0
With help from Connor O'Brien and Alex Nieves WELCOME TO POLITICO PRO SPACE. NASA interim administrator Sean Duffy made a splash this week with his first directives at the agency, including advancing plans for a nuclear reactor on the moon. What's your opinion of the new administrator? Should President Donald Trump just keep him in the post or continue the search for a permanent head? Email me at sskove@ with tips, pitches and feedback, and find me on X at @samuelskove. And remember, we're offering this newsletter for free over the next few weeks. After that, only POLITICO Pro subscribers will receive it. Read all about it. The Spotlight The Pentagon has poured millions of dollars into preparing for a threat from Beijing on land and at sea. But U.S. officials increasingly worry they're missing the chance to tackle another big risk: China in space. Rep. Brian Babin (R-Texas), chair of the committee that oversees NASA, warned this week that American astronauts might land on the moon and be greeted by a 'no trespassing' sign in Mandarin if the U.S. doesn't step up. Some of the rhetoric is akin to orbital debris. But the U.S. does face challenges from China in both military and commercial space. Beijing could weaponize satellites and other tools to prevent the U.S. from helping Taiwan — or anyone else — in a conflict. And if the Chinese government plants a flag on the moon, it could bar American access to lucrative new resources on the lunar surface. China ascendant: Beijing is second only to America in its vast array of space capabilities, according to Chinese space expert Blaine Curcio. And, in some cases, it now surpasses the U.S. For example, China in July attempted the first-ever satellite refueling in orbit. China is also figuring out how to knock out satellites that allow the U.S. to communicate in the Pacific, said Dean Cheng, a nonresident fellow at the Space Policy Institute. 'The Chinese have been very carefully and assiduously developing an array of military counter space options.' But the commercial use of many space tools makes it harder to figure out what's actually a threat. Chinese satellites that can move debris, for instance, may also be able to eviscerate an American satellite. 'China isn't big on transparency,' said Victoria Samson, a space expert at the Secure World Foundation, a space-focused think tank. Moon dance: China also has plans to land an astronaut on the moon by 2030 and set up a permanent base. Such a move would dent American prestige, as it would no longer be the only nation to land on the lunar surface. It would also allow Beijing to write the terms for potentially lucrative space exploration. 'We're in a race to the moon, in a race with China to the moon,' Duffy said Tuesday at a press conference. China already has shown it can pull off complex uncrewed lunar missions. Beijing recently used its Chang'e 6 to land a rover on the moon and return samples to Earth. The U.S. aims to return to the lunar surface in 2027, before China gets there. But the timeline has slipped before due to spacecraft issues, and it could happen again. Room for hope: Beijing has been less successful when it comes to the commercial sector, which the U.S. dominates. Think reusable rockets and low-earth satellite constellations such as Starlink. This is despite the Chinese government's effort to supercharge the growth of a commercial space sector through investments and other support, such as free land or factory space. But so far, there are more companies than space services. 'You have this absence of real demand,' Curcio said. 'And then you've also had all this government money coming in and creating oversupply in some situations.' The high number of companies may also dilute the ability of any single firm since they're competing for the same specialized engineering talent, he said. 'You're not going to really have a critical mass of highly talented rocket scientists working for any one company.' Galactic Government SpaceX vs. California: The fight between Elon Musk's SpaceX and the California agency tasked with protecting the state's coastline is back on. Space Force officials will stand in front of the California Coastal Commission next week with a plan to double the company's rocket launches from Vandenberg Space Force Base from 50 to 95 per year. And the agency staff is recommending commissioners reject it. 'The simple fact remains that it is a privately owned company engaged in activities primarily for its own commercial business,' staff said in a Friday report. 'It is not a public federal agency or conducting its launches on behalf of the federal government.' That argument mirrors commissioners' pushback in October when they rejected an increase from 36 to 50 launches. SpaceX sued the agency for bias after members cited Musk's politics. Space Force ultimately moved forward with the increase, citing federal preemption and national security considerations. SpaceX did not respond to a request for comment. Space Launch Delta 30 Commander Col. James T. Horne III, who oversees Vandenberg and Western operations, noted the military's 'unwavering commitment to preserving the California coastline' and said its partnership with SpaceX allows the agency to maintain 'its technological edge and strategic advantage over competitors.' Military SPACE FORCE GETS NEW NO. 2: The Space Force has a new no. 2 officer on the job. The Senate quietly approved Gen. Shawn Bratton for vice chief of space operations last week and promoted him to a four-star general before leaving town until September. He officially took over on July 31, the same day he was confirmed. Bratton succeeds Gen. Michael Guetlein, who was approved in July to oversee the nascent — and nebulous — Golden Dome missile defense shield. Bratton was most recently the Space Force's deputy chief for strategy, plans, programs and requirements. That made him a key player in the development of the recently released Space Warfighting Framework, the service's blueprint for how it would conduct war in space. He was also the first commander of the Space Training and Readiness Command, which leads training for the Space Force. He began his military career as an enlisted member of the Arizona Air National Guard. Bratton was part of a larger tranche of officers whose promotions were confirmed before the Senate recessed.

Earth or Mars? See the 'deceptively' clear blue sky spotted on the Red Planet
The Martian forecast will almost always include a red sky, but a recent panorama captured by NASA's rover Perseverance shows what a blue sky would look like on the Red Planet. Iron in the dust on Mars is what gives the planet its rusty hue. In its natural color, a photo taken at a location dubbed "Falbreen" is very red. In the name of science, imaging teams enhanced the color-contrast on the image to reveal more details. Largest Chunk Of Mars Discovered On Earth Sells At Auction For $5.3 Million The final panoramic image is a mosaic of 96 images taken at a location by the Perseverance rover. "The relatively dust-free skies provide a clear view of the surrounding terrain," said Jim Bell, Mastcam-Z's principal investigator at Arizona State University in Tempe. "And in this particular mosaic, we have enhanced the color contrast, which accentuates the differences in the terrain and sky." The image below is not enhanced and shows the true reddish tint of the clear Martian sky. Cool Rocks: Nasa's Mars Rover Shows Off Its Rock Core Collection The bright white patch in the image left of the center is where Perseverance drilled its 43rd hole since its landing. Drilling into the red rock and dirt allows the rover's science team to see what is below before deciding to take a sample.
