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.

In a groundbreaking new report from Reuters, SpaceX is reportedly discussing merger possibilities with xAI ahead of the space exploration company’s plans to IPO later this year, in what would be a blockbuster move.

The outlet said it would combine rockets and Starlink satellites, as well as the X social media platform and AI project Grok under one roof. The report cites “a person briefed on the matter and two recent company filings seen by Reuters.”

Musk, nor SpaceX or xAI, have commented on the report, so, as of now, it is unconfirmed.

With that being said, the proposed merger would bring shares of xAI in exchange for shares of SpaceX. Both companies were registered in Nevada to expedite the transaction, according to the report.

On January 21, both entities were registered in Nevada. The report continues:

“One of them, a limited liability company, lists SpaceX ​and Bret Johnsen, the company’s chief financial officer, as managing members, while the other lists Johnsen as the company’s only officer, the filings show.”

The source also stated that some xAI executives could be given the option to receive cash in lieu of SpaceX stock. No agreement has been reached, nothing has been signed, and the timing and structure, as well as other important details, have not been finalized.

SpaceX is valued at $800 billion and is the most valuable privately held company, while xAI is valued at $230 billion as of November. SpaceX could be going public later this year, as Musk has said as recently as December that the company would offer its stock publicly.

SpaceX IPO is coming, CEO Elon Musk confirms

The plans could help move along plans for large-scale data centers in space, something Musk has discussed on several occasions over the past few months.

At the World Economic Forum last week, Musk said:

“It’s a no-brainer for building solar-powered AI data centers in space, because as I mentioned, it’s also very cold in space. The net effect is that the lowest cost place to put AI will be space and that will be true within two to three years, three at the latest.”

He also said on X that “the most important thing in the next 3-4 years is data centers in space.”

If the report is true and the two companies end up coming together, it would not be the first time Musk’s companies have ended up coming together. He used Tesla stock to purchase SolarCity back in 2016. Last year, X became part of xAI in a share swap.

Tesla CEO Elon Musk trolls budget airline after it refuses Starlink on its planes

“I really want to put a Ryan in charge of Ryan Air. It is your destiny,” Musk said.

Tesla CEO Elon Musk trolled budget airline Ryanair on his social media platform X this week following the company’s refusal to adopt Starlink internet on its planes.

Earlier this week, it was reported that Ryanair did not plan to install Starlink internet services on its planes due to its budgetary nature and short flight spans, which are commonly only an hour or so in total duration.

Initially, Musk said installing Starlink on the company’s planes would not impact cost or aerodynamics, but Ryanair responded on its X account, which is comical in nature, by stating that a propaganda it would not fall for was “Wi-Fi on planes.”

Musk responded by asking, “How much would it cost to buy you?” Then followed up with the idea of buying the company and replacing the CEO with someone named Ryan:

Polymarket now states that there is an 8 percent chance that Musk will purchase Ryanair, which would cost Musk roughly $36 billion, based on recent financial data of the public company.

Although the banter has certainly crossed a line, it does not seem as if there is any true reason to believe Musk would purchase the airline. More than anything, it seems like an exercise of who will go further.

However, it is worth noting that if something is important enough, Musk will get involved. He bought Twitter a few years ago and then turned it into X, but that issue was much larger than simple banter with a company that does not want to utilize one of the CEO’s products.

In a poll posted yesterday by Musk, asking whether he should buy Ryanair and “restore Ryan as their rightful ruler.” 76.5 percent of respondents said he should, but others believe that the whole idea is just playful dialogue for now.

But it is not ideal to count Musk out, especially if things continue to move in the direction they have been.

SpaceX employees, including its CEO Elon Musk, shaded American Airlines on social media this past weekend due to the company’s reported talks with Amazon’s Starlink rival, Leo.

Starlink has been adopted by several airlines, including United Airlines, Qatar Airways, Hawaiian Airlines, WestJet, Air France, airBaltic, and others. It has gained notoriety as an extremely solid, dependable, and reliable option for airline travel, as traditional options frequently cause users to lose connection to the internet.

Many airlines have made the switch, while others continue to mull the options available to them. American Airlines is one of them.

A report from Bloomberg indicates the airline is thinking of going with a Starlink rival owned by Amazon, called Leo. It was previously referred to as Project Kuiper.

American CEO Robert Isom said (via Bloomberg):

“While there’s Starlink, there are other low-Earth-orbit satellite opportunities that we can look at. We’re making sure that American is going to have what our customers need.”

Isom also said American has been in touch with Amazon about installing Leo on its aircraft, but he would not reveal the status of any discussions with the company.

The report caught the attention of Michael Nicolls, the Vice President of Starlink Engineering at SpaceX, who said:

“Only fly on airlines with good connectivity… and only one source of good connectivity at the moment…”

CEO Elon Musk replied to Nicolls by stating that American Airlines risks losing “a lot of customers if their connectivity solution fails.”
