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 adjusts Starship Flight 13 test launch target date once again

Published

SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.

The target flight was initially rescheduled for today, but SpaceX pushed it back again.

This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.

SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.

This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.

SpaceX comes with a slew of changes for Starship Flight 13

Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.

Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.

For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.

Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.

The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.

This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.

Elon Musk debunks $52 billion SpaceX-NVIDIA GPU deal

Published

Elon Musk dismissed reports claiming SpaceX had placed a massive order for NVIDIA GPUs worth $52 billion. The denial came hours after Taiwanese media, citing unnamed industry sources, reported that SpaceX planned to acquire approximately 13,000 AI server racks, equating to roughly 1 million GB300 GPUs, from Foxconn.

Each rack was estimated at around $4 million, with deliveries potentially starting in late 2025.

The story suggested this would mark SpaceX’s first major foray into Foxconn-manufactured NVIDIA hardware, breaking from suppliers like Supermicro and Dell. Musk responded bluntly on X:

Despite the denial, the rumored scale aligns with SpaceX’s explosive growth in AI infrastructure. NVIDIA’s GB300 (successor to the GB200 NVL) racks deliver unprecedented performance for large-scale training and inference. A $52 billion commitment would dwarf most corporate AI budgets and provide the compute muscle needed for frontier models.

SpaceX already operates gigawatt-scale terrestrial clusters like Colossus in Memphis, Tennessee, and has monetized them aggressively through leasing deals.

Major customers include Anthropic (paying ~$1.25 billion monthly for 220,000+ GPUs), Google (~$920 million monthly for 110,000 GPUs), and Reflection AI. These arrangements are projected to generate tens of billions in annual revenue, far outpacing traditional SpaceX businesses.

Such an investment would fuel internal AI efforts, particularly Grok models under the integrated SpaceXAI division, while supporting ambitious orbital data center plans. SpaceX envisions launching thousands of AI-optimized satellites powered by solar energy and cooled in space, bypassing terrestrial power and land constraints.

This “Starmind” constellation could position the company as a leader in space-based computing.

SpaceX as an Emerging AI Powerhouse

Once primarily known for reusable rockets and Starlink satellite internet, SpaceX has transformed into a multifaceted AI player.

The 2026 acquisition of xAI integrated Grok development directly into the company. Starlink’s low-latency global network complements massive compute clusters, enabling efficient data flow for training and serving AI models.

Musk has long argued that AI scaling demands solutions beyond Earth, citing things like real estate and electricity limits on the ground.

While the Foxconn deal may not be in the cards, SpaceX’s trajectory is continuing on the path of blending aerospace engineering with hyperscale AI to dominate both launches and intelligence infrastructure.

Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.

For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.

Ultimately, it will splash down in the Indian Ocean.

The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.
