Have you ever tuned in to your favorite radio station only to hear another station playing on top of it? That’s a result of a weird atmospheric phenomenon called a sporadic E layer.

The Earth’s upper atmosphere, called the ionosphere, is a region full of charged particles. Those particles can be blown about by the wind, forming clumps called sporadic E layers. These dense layers of ions are constantly in flux appearing and disappearing at random which can be disruptive to radio communications.

With the help of the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, NASA scientists have discovered the same phenomenon at Mars, which will help scientists better understand them.  Even though these layers are quite common here on Earth, they form at altitudes that are very difficult to explore.

Mars has a thinner atmosphere that allows spacecraft, like MAVEN, to fly at lower altitudes and observe many of these weird layers.

“The low altitudes observable by MAVEN will fill in a great gap in our understanding of this region on both Mars and Earth, with really significant discoveries to be had,” Joe Grebowsky, a former MAVEN project scientist at Goddard, said in a statement.

MAVEN uncovered two types of structures — called layers and rifts — while studying the Martian ionosphere. The layers typically form suddenly and last for hours, acting like a mirror and reflecting radio signals. Scientists have known about the existence of these layers for a decade but have never been able to study them in detail until now.

“The layers are so close above all our heads at Earth and can be detected by anyone with a radio, but they are still quite mysterious,” Glyn Collinson of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author on the study explained in the same statement. “Who would have thought one of the best ways to understand them is to launch a satellite 300 million miles to Mars?”

In total, the team found 34 E layers in the MAVEN data. They form higher in the Martian atmosphere and are probably too high to interfere with any future radio communications on the ground, which is good news for future human missions.

But they are troublesome here on Earth. In addition to interfering with your radio listening enjoyment, they can also block crucial radar signals that track things like aircraft and missiles.

In addition to the layers, MAVEN also found “rifts” in the planet’s atmosphere. These are gaps in the plasma basically the opposite of a layer. These areas have never been spotted on Earth.

One thing the team noticed in the data is that the layers and rifts seem to always form at the same places. They think that’s because of how the charged particles in Mars’s ionosphere react to its tangled magnetic field.

This observation could make them much easier to find and predict at Mars, which could help scientists identify them easier here on Earth and mitigate their effects.

SpaceX has exercised its option to acquire Cursor, the innovative AI coding company, in an all-stock transaction valued at $60 billion. The deal, announced on June 16, marks a significant step in SpaceX’s expansion into advanced artificial intelligence, building on months of close collaboration between the companies.

Cursor, officially operated by Anysphere, Inc., is an AI-native code editor and coding agent designed to transform software development. Founded in 2022 by a group of MIT graduates in San Francisco, Cursor builds on the familiar foundation of Visual Studio Code but integrates powerful AI capabilities directly into the core experience.

Unlike traditional code editors or simple extensions, Cursor functions as a full “coding agent” that turns natural-language instructions into actionable code.

Developers interact with Cursor through features like its Composer agent, which can search entire codebases, edit multiple files, run terminal commands, debug issues, and complete complex multi-step programming tasks autonomously.

Users describe high-level goals, such as “build a scalable API endpoint with authentication,” and the AI plans, implements, tests, and refines the solution while the human oversees decisions. Additional tools include advanced autocomplete (Tab), context-aware chat, and infrastructure for handling billions of daily requests.

The platform has gained considerable traction, surpassing $3 billion in annual recurring revenue by early 2026 and earning adoption by over half of the Fortune 500 companies. Its agentic approach accelerates development dramatically, allowing engineers to focus on architecture and creativity rather than repetitive coding.

The acquisition integrates Cursor’s leading product, expert team of roughly 300 engineers, and distribution network among top software developers with SpaceX’s unparalleled computational resources. SpaceX’s Colossus supercomputer, equivalent to a million H100 GPUs, has already powered joint training of next-generation models. These models are expected to launch soon within Cursor and SpaceX’s Grok Build environment.

This combination positions SpaceX to develop the world’s most capable AI systems for coding and knowledge work. Access to Cursor’s real-world usage data from millions of professional developers provides unparalleled feedback loops for model improvement. Training on Colossus enables rapid iteration on massive datasets, potentially creating AI that outperforms current leaders in reliability, context handling, and complex reasoning.

For SpaceX, the benefits extend far beyond software tools. Rocket engineering, satellite constellation management, autonomous flight systems, and Starship development involve millions of lines of highly specialized, safety-critical code.

Ron Baron on Tesla stock

Renowned investor Ron Baron, founder and CEO of Baron Capital, has once again demonstrated his unwavering faith in Elon Musk’s ventures.

Just after SpaceX’s record-breaking IPO, Baron announced he purchased an additional $1 billion in SpaceX (NASDAQ: SPCX) shares. This move pushes Baron Capital’s total holdings in the company to a staggering $25 billion in market value, underscoring one of the most successful private-to-public investment stories in recent history.

Baron’s relationship with SpaceX dates back to 2017, when his firm began investing approximately $1.75–2 billion through secondary markets and employee tender offers at valuations around $20–22 billion.

By the time of the IPO, which valued SpaceX at over $2 trillion with shares closing near $161, those early stakes had generated more than $13 billion in unrealized gains. Post-IPO, Baron’s position ballooned further, reflecting the company’s meteoric rise driven by reusable rocketry, Starlink’s global satellite internet constellation, Starshield defense applications, and ambitious plans for orbital infrastructure.
