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.

Elon Musk reveals when SpaceX will perform first-ever Starship catch
“Starship catch is probably flight 13 to 15, depending on how well V3 flights go,” Musk said.

Elon Musk revealed when SpaceX would perform the first-ever catch attempt of Starship, its massive rocket that will one day take life to other planets.
On Tuesday, Starship aced its tenth test flight as SpaceX was able to complete each of its mission objectives, including a splashdown of the Super Heavy Booster in the Gulf, the deployment of eight Starlink simulators, and another splashdown of the ship in the Indian Ocean.
It was the first launch that featured a payload deployment:
SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative
SpaceX was transparent that it would not attempt to catch the Super Heavy Booster, something it has done on three previous occasions: Flight 5 on October 13, 2024, Flight 7 on January 16, and Flight 8 on March 6.
This time, it was not attempting to do so. However, there are bigger plans for the future, and Musk detailed them in a recent post on X, where he discussed SpaceX’s plans to catch Starship, which would be a monumental accomplishment.
Musk said the most likely opportunities for SpaceX to catch Starship itself would be Flight 13, Flight 14, and Flight 15, but it depends on “how well the V3 flights go.”
The Starship launched with Flight 10 was a V2, which is the same size as the subsequent V3 rocket but has a smaller payload-to-orbit rating and is less powerful in terms of initial thrust and booster thrust. Musk said there is only one more V2 rocket left to launch.

V3 will be the version flown through 2026, as V4, which will be the most capable Starship build SpaceX manufactures, is likely to be the first company ship to carry humans to space.
Musk said that SpaceX planned to “hopefully” attempt a catch of Starship in 2025. However, it appears that this will likely be pushed back to 2026 due to timing.
SpaceX will take Starship catch one step further very soon, Elon Musk confirms
SpaceX would need to launch the 11th and 12th test flights by the end of the year in order to get to Musk’s expected first catch attempt of Flight 13. It’s not unheard of, but the company will need to accelerate its launch rate as it has only had three test flights this year.

SpaceX aces Starship test flight 10 with successful payload deployment
The mission began at 6:30 p.m. local time in Starbase, Texas, when the launch of Starship initiated. After about eight minutes, stage separation was completed, and the Super Heavy Booster headed back down to Earth for a planned splashdown in the Indian Ocean:

SpaceX aced its tenth Starship test flight on Tuesday night after multiple delays pushed the mission back to this evening. Originally scheduled for Sunday night, SpaceX had two delays push the flight back to Tuesday, which ultimately provided ideal conditions for a launch attempt.
The tenth test flight of Starship had several objectives, including a successful splashdown of the booster in the Gulf of America, the deployment of eight Starlink simulation modules from the PEZ dispenser, and a splashdown of the ship in the Indian Ocean.
SpaceX successfully achieved all three of these objectives, making it one of the most successful test flights in the Starship program. There was no attempt to catch the booster this evening, as the company had been transparent about it ahead of the launch.

Starship was then the main focus of the rest of the broadcast as it completed its ascent burn and coasted through space, providing viewers with spectacular views as the mission headed toward new territory, including the deployment of Starlink simulators. This would be the first time SpaceX would attempt a payload deployment.
The deployment works like a PEZ dispenser, as the simulators were stacked on top of one another and would exit through a small slit one at a time.
This occurred roughly 20 minutes into the mission:

An hour and six minutes into the flight, Starship reached its final destination, which was the Indian Ocean. A successful splashdown would bring closure to Starship’s tenth test flight, marking the fifth time a test flight in the program’s history did not end with vehicle loss.
It was also the first of four test flights this year that will end with Starship being recovered.

SpaceX is expected to launch Starship again in approximately eight weeks, pending the collection of data and other key metrics from this flight.

WATCH: SpaceX attempts Starship’s tenth test flight after two delays
This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.

SpaceX is set to launch Starship tonight, provided the weather cooperates and everything with the ship goes smoothly.
This is SpaceX’s third attempt to launch Starship for its tenth test flight, with Sunday’s and Monday’s attempts both being scrapped due to a leak and unfavorable weather conditions on the respective days.
This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.
Propellant load of the upper stage and Super Heavy booster is already underway, and the launch is expected to occur at 6:30 p.m. in Starbase, Texas.
