Mars’ atmosphere could help us better understand radio interference here on Earth
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.
The research was published in a paper in the journal Nature Astronomy.
SpaceX has revealed the date for the maiden voyage of Starship v3, its newest and most advanced version of the rocket yet.
Starship v3 represents a significant leap forward. At 124 meters tall when fully stacked, it stands taller than previous versions and boasts substantial upgrades.
The vehicle incorporates next-generation Raptor 3 engines, which deliver higher thrust, improved reliability, and simplified designs with fewer parts. Both the Super Heavy booster (Booster 19) and the Starship upper stage (Ship 39) feature these enhancements, along with structural improvements for greater payload capacity—exceeding 100 metric tons to low Earth orbit in reusable configuration.
SpaceX and its CEO Elon Musk have announced that the company aims to push the first launch of Starship v3 this Thursday. Musk included some clips of past Starship launches with the announcement.

There are a lot of improvements to Starship v3 from past builds. Key hardware changes include a more robust heat shield, upgraded avionics, and modifications optimized for orbital refueling, a critical technology for future missions to the Moon and Mars. This flight marks the first launch from Starbase’s second orbital pad, allowing parallel operations and accelerating the cadence of tests.
This will be the 12th Starship launch for SpaceX. Flight 12 objectives include a full ascent profile, hot-staging separation, in-space engine relights, and reentry testing. The booster is expected to perform a controlled splashdown in the Gulf of Mexico, while the ship will deploy 20 Starlink simulator satellites and a pair of modified Starlink V3 units before attempting reentry.
Success would validate V3’s design for operational use, paving the way for rapid reusability and higher flight rates.
The rapid evolution from V2 to V3 underscores SpaceX’s iterative approach. Previous flights demonstrated booster catches, ship landings, and heat shield advancements. V3 builds on these with nearly every component refined, supported by an expanding production line at Starbase that churns out vehicles at an unprecedented pace.
Starship V3 is here putting SpaceX closer to Mars than it has ever been
This launch comes amid growing momentum for SpaceX’s ambitious goals. Starship is central to NASA’s Artemis program for lunar landings and Elon Musk’s vision of making humanity multiplanetary. A successful V3 debut would boost confidence in achieving orbital refueling and crewed missions in the coming years.
As excitement builds, enthusiasts and engineers alike await liftoff. Weather and technical readiness will determine the exact timing, but the community is optimistic. Starship V3 is poised to push the boundaries of spaceflight once again, bringing reusable interplanetary transport closer to reality.

Starship V3 is here putting SpaceX closer to Mars than it has ever been
Starship V3 launches May 20 carrying the hardware upgrades that make Moon and Mars possible.
SpaceX is preparing to fly the most significant version of Starship yet. Flight 12, the debut of Starship V3, is targeted for Wednesday, May 20, lifting off from Starbase in South Texas at 6:30 p.m. ET. It will also mark the first launch from the newly built Pad 2, adding another layer of firsts to an already milestone-heavy mission.
Starship V3 is a meaningful step up from what came before, and a next-gen design that improves on raw power and payload capacity. V3 can carry more than 100 metric tons to orbit in reusable configuration, which is roughly three times what the previous version could handle. Additionally, the new design is lighter and simpler than before, thereby reducing risk of component failure, while also reducing flight costs. The launch pad itself is also brand new, meaning SpaceX can now prepare two rockets at the same time instead of one. What makes all of this matter beyond the hardware is what it unlocks. NASA needs V3 to be reliable enough to land astronauts on the Moon, and Musk needs it to eventually carry people and cargo to Mars at a scale that makes a permanent settlement financially possible. Every previous Starship was essentially a prototype. V3 is the version SpaceX actually intends to put to work.
On May 7, SpaceX completed the first full-duration, full-thrust 33-engine static fire with the V3 Super Heavy, following two earlier attempts that ended early due to ground equipment issues. The Ship stage had already cleared its own static fire in April, making Flight 12 the first time both V3 vehicles have been cleared to fly together.
The stakes extend well beyond this single test. As Teslarati reported, NASA needs Starship to work as the Human Landing System for its Artemis program, with a crewed lunar landing now targeted for 2028 under Artemis IV. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring more than ten tanker launches to fuel a single Moon mission. V3 is the vehicle designed to make that economically viable.
Elon Musk has stated that Starship V3 should be capable enough for initial Mars missions, a detail that connects directly to his January 2026 compensation package, which awards him 200 million shares if SpaceX reaches a $7.5 trillion valuation and helps establish a permanent Mars colony of one million people. With SpaceX targeting a Nasdaq IPO as early as June 12 at a valuation of $1.75 trillion, and holding more than $22 billion in active government contracts spanning defense, NASA, and broadband, every successful Starship test adds tangible weight to that number.
Elon Musk cannot be fired from SpaceX, and there’s a reason for that.
In a blunt post on X on Friday, Elon Musk confirmed plans to structurally shield his leadership at SpaceX, ensuring he cannot be fired while tying a potential trillion-dollar compensation package to the company’s long-term goal of establishing a self-sustaining colony on Mars.
Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!
Obviously, IF SpaceX succeeds in this absurdly difficult goal, it will be worth many orders of…
— Elon Musk (@elonmusk) May 15, 2026
The revelation stems from a Financial Times report detailing SpaceX’s intention to restructure its governance and compensation framework. The moves are designed to protect Musk’s control and align his incentives with the company’s founding mission rather than short-term financial pressures. Musk’s reply left no ambiguity:
“Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!”
He added that success in this “absurdly difficult goal” would generate value “many orders of magnitude more than the economy of Earth,” though he cautioned that the journey will not be smooth. “Don’t expect entirely smooth sailing along the way,” Musk wrote.
The strategy reflects Musk’s deep concerns about how public-market expectations could derail SpaceX’s core objective. Founded in 2002, SpaceX has repeatedly stated its purpose is to reduce the cost of space travel and ultimately make humanity a multiplanetary species.
Unlike Tesla, which went public in 2010 and has faced repeated battles over Musk’s compensation and board influence, SpaceX remains privately held. Musk has long resisted taking the rocket company public precisely to avoid the quarterly earnings treadmill that forces most CEOs to prioritize short-term stock performance over ambitious, high-risk projects.
By embedding protections against his removal and linking any outsized pay package to verifiable milestones—such as a functioning Mars colony—SpaceX aims to insulate its leadership from activist investors or board members who might demand faster profits or safer bets.
Musk has referenced past experiences, including his ouster from OpenAI and shareholder lawsuits at Tesla, as cautionary tales. In those cases, he argued, external pressures risked diluting the original vision.
Critics may view the arrangement as excessive, especially given Musk’s already substantial voting power and wealth. Supporters, however, argue it is a necessary safeguard for a company pursuing goals measured in decades rather than quarters. Achieving a Mars colony would require sustained investment in Starship development, orbital refueling, life-support systems, and in-situ resource utilization—technologies that may deliver no immediate financial return.
Musk’s post underscores a broader philosophical point: true breakthrough innovation often demands tolerance for volatility and a willingness to ignore conventional business wisdom. As SpaceX prepares for increasingly ambitious Starship test flights and eventual crewed missions, the new governance structure signals that the company’s North Star remains unchanged—humanity’s expansion beyond Earth.
Whether the trillion-dollar package materializes depends on execution, but Musk’s message is clear: SpaceX exists to reach the stars, not to chase the next earnings beat. For investors or employees who share that vision, the protections are not a perk—they are a prerequisite for success.
