Scientists are looking at Mars in a whole new way. That’s because a new analysis of a famous piece of the red planet has revealed something exciting: traces of nitrogen.

Nitrogen, together with organic molecules — carbon-rich molecules that are considered the building blocks of life as we know it — have been spotted in the Alan Hills meteorite, a new study suggests. 

The Alan Hills sample was discovered in Antarctica in 1984 and is one of the largest, most famous meteorites from Mars. That’s because it sparked quite the controversy when it was first found. Some of the first analysis of the rock suggested that the sample contained microbial fossils. This led to rumors that scientists might have spotted their firsts signs of Martian life.

Over billions of years, Mars has been stripped of its atmosphere, and as such, its surface is subjected to cosmic radiation as well as blasts from interstellar objects. Sometimes the blasts are so powerful that chunks of rock are ejected into space and eventually land on other planetary bodies such as the moon or Earth.

Scientists estimate that the Alan Hills sample arrived on our planet at least 13,000 years ago and that the sample itself is around 4 billion years old. This 4-lb. chunk of rock is the oldest known meteorite from Mars that we’ve found.

Mars, as we know it today, appears to be a pretty inhospitable place for life. But that wasn’t always the case. Mars was once a lush, wet world, and new evidence points to the fact that an ancient chunk of the red planet is harboring traces of organic molecules.

These types of carbon-rich molecules are the building blocks of life. Their presence does not necessarily qualify as a definitive sign that life was once present on Mars, but it bolsters the case. That’s because this particular sample doesn’t just contain a random set of organic molecules; it contains traces of nitrogen explicitly.

And nitrogen is something that life here on Earth depends on.

The Allan Hills 84001 meteorite is a famous hunk of Martian rock that was found in a region of Antarctica called Allan Hills in 1984. The new study, conducted by a group of researchers from the Japanese Space Agency (JAXA), indicates that not only does the sample contain nitrogen, but that the nitrogen was found within carbonate minerals in the rock. These types of minerals typically form in groundwater, so this could be further evidence to support the notion that Mars was once a wet world.

To make this discovery, the team from JAXA, led by Mizuho Koike, used a technique called X-ray spectroscopy to determine that the nitrogen was hiding in the carbonate minerals. Even though the Alan Hills sample has been in the news before, this was the first definitive evidence that there was nitrogen in the meteorite.

This discovery does not mean that the researchers have found signs of life on Mars. The presence of nitrogen and the carbonate minerals can be produced both biotically and abiotically. Scientists do not yet know how these molecules formed, but they have ruled out that they were somehow contaminated by Earth minerals.

But how were they formed? According to the researchers, there are two possibilities: either the organics originated on Mars, or they came from outside the planet. Mars was bombarded by comets and other rock and dust particles, and it’s possible that some of them may have been trapped inside the minerals as they formed.

Researchers will soon have other Martian rocks to compare these results to. This summer, NASA is launching the Perseverance Mars rover. The six-wheeled robot will land in on Mars in a region called Jezero Crater. The agency selected this spot as the landing site because it’s believed to be an ancient river delta and could contain minerals known to preserve microfossils here on Earth.

The rover’s task will be to search for signs of a past life as well as to bag up samples that will be sent to Earth on later missions. Once researchers have access to pristine Martian samples, they will be able to expand their knowledge of the red planet. And perhaps even be able to tell if Mars ever hosted life.

SpaceX’s Starlink Router Mini targets home Wi-Fi dead zones for $40

The Starlink Router Mini tackles home Wi-Fi dead zones for just $40. Compact & mesh-compatible, it’s built for basic setups.

SpaceX’s Starlink Router Mini recently launched to enhance home Wi-Fi connectivity by addressing dead zones at home, offering a budget-friendly option for customers. The Starlink Router Mini is a $40 mesh-compatible device.

The Router Mini targets users seeking affordable solutions to extend coverage in smaller spaces. SpaceX describes the new Starlink router as a lower-performance device suited for “basic Wi-Fi needs” in compact setups.

“It works well in most basic residential setups and is a good option for extending coverage. However, in homes where rooms have multiple barriers between them (mirrors, multiple walls, brick or stone walls), you may notice a drop in performance unless you use wired connections,” the company noted.

In contrast, the Gen 3 router, now priced at $120 after dropping from $199, delivers stronger performance for larger homes with multiple devices. The Router Mini complements the Gen 3 router, which comes bundled with the standard Starlink dish and supports mesh networking.

“If you need simple, reliable Wi-Fi and want to keep costs down, the Router Mini is a solid option. But if you’re looking for stronger, more consistent performance across a larger or busier home, the Gen 3 Router is the way to go,” SpaceX explained.

Both routers support Wi-Fi 6 speeds and can operate in wired or wireless mesh modes, though the dual-band Starlink Router Mini has fewer antennas (“2×2 2.4 GHz, 2×3 5 GHz MU-MIMO”) compared to the tri-band Gen 3’s four-plus antenna setup.

The Router Mini’s debut follows its appearance in an FCC filing and a Starlink app update referencing a “mini mesh” device. It also connects to the Starlink Mini dish, boosting its limited Wi-Fi range. The device’s affordability and mesh compatibility make it an attractive option for customers looking to optimize their Starlink setup without investing in additional Gen 3 routers.

As Starlink continues to expand its global broadband network, the Router Mini addresses growing demand for flexible, cost-effective home connectivity solutions. By offering a cheaper mesh device, SpaceX strengthens its ecosystem, catering to diverse user needs while maintaining its lead in satellite internet innovation.

SpaceX secures FAA approval for 25 annual Starship launches

SpaceX scored FAA approval for up to 25 Starship launches annually. The agency found no major environmental impact, but critics remain skeptical.

SpaceX secured Federal Aviation Administration (FAA) approval to launch and land Starship rockets and Super Heavy boosters from its Starbase spaceport in Boca Chica, Texas, up to 25 times a year. The FAA’s decision was announced on Tuesday, marking a pivotal step for SpaceX’s ambitious space exploration goals.

The FAA’s SpaceX approval is part of its ongoing license review. The agency noted that “there are other licensing requirements still to be completed,” including evaluations of policy, payload, safety, financial responsibility, and environmental impacts.“Once the evaluation process is complete, the FAA will make a determination to approve or deny the license application,” the agency added.

The FAA’s final environmental assessment concluded that SpaceX’s expanded launch plans would have “no significant impact” on the surrounding environment, defying a history of legal disputes with environmental groups.

The ruling follows a significant weekend for Starbase, where residents—mostly SpaceX employees—voted to incorporate the area as a city. Starbasee City includes a mayor and two commissioners from the aerospace company’s ranks. The FAA’s decision amplifies SpaceX’s momentum but has sparked concerns among environmentalists.

Christopher Basaldu of the South Texas Environmental Justice Network called the environmental assessment premature.

“You’re bragging about the big slot rocket in history, and then you’re also trying to claim that it makes no environmental impact; that’s impossible. So they’re lying. So what the FAA needs to do is they need to go all the way back to square one,” Basaldu said.

Basaldu highlighted potential harm to marine life, pollution risks to the nearby Rio Grande, and disruptions from noise and night operations coming from SpaceX launches.

“A lot of noise pollution. That’s not a lot of night pollution, because they try to continue working through the night, while SpaceX is going to shut down the road for half of the year.”

As SpaceX pushes to scale Starship operations, the FAA’s approval underscores Starbase’s growing role in space exploration. However, ongoing environmental reviews and local concerns signal challenges ahead, balancing innovation with ecological and community impacts.
