‘A historic moment’: NASA Perseverance rover collects first ever Mars rock sample

The rock core could be destined for Earth, eventually, but mailing it home will be a whole other ordeal.

NASA’s Perseverance rover, currently rolling around a dried out lakebed on the surface of Mars, has completed the first, critical step in a decade-long mission to return pieces of Mars to Earth. On the 190th day of its mission «Percy,» as the rover is affectionately known, overcame earlier sampling problems and snatched a core of rock, slightly thicker than a pencil, from Mars’ surface.

On Sept. 1, the space agency announced data had arrived from the Mars rover indicating it had successfully obtained a core from a briefcase-sized rock known as «Rochette.» But the team wanted to be «extra certain» that was the case. To be sure, the rover would need to take a few photographs of the drill device with one of its cameras.

The first images beamed back to Earth appeared to show rock had been successfully snatched. However, after an operation to vibrate the drill bit, a second round of images were taken. The sun, however, was not playing nicely with Percy. The lighting conditions were too poor to confirm exactly what was in the tube — and the team wanted to be doubly sure.

On Saturday, they got their wish.

Adam Steltzner, NASA chief engineer on the mission, tweeted his congratulations on Sep. 4. «We got it,» he wrote.

«For all of NASA science, this is truly a historic moment,» said Thomas Zurbuchen, NASA’s associate administrator for science.

The early images show a rust-red sediment that could be iron-rich minerals, according to Steven Ruff, a planetary geologist at Arizona State University and creator of YouTube channel Mars Guy. Percy’s landing site in Jezero Crater was once home to a great body of water and its two sampling attempts are already revealing some of the geologic history of Mars. «Both of those rock targets that they’ve interrogated look different than really anything that we’ve seen anywhere else on Mars,» Ruff says.

The successful collection is part 1 of the most elaborate and complex mail run of all time.

Getting the Martian rock core in the sampling tube is like placing a letter in an envelope. The next step is for Perseverance to process, seal and stamp that envelope and get it ready to send. Perseverance has 43 of these envelopes and can collect dozens of diverse rock samples. On Monday, NASA announced the rover had stored the sample in its interior, locked away in an airtight titanium tube. (I’m sure this will become a trivia question in the future so, for reference, the very first sample was stored in tube number 266)

Percy intends to leave these titanium tube-letters scattered across the surface of Mars for a mail carrier to collect at a later date. The key issue here is: The mail carrier hasn’t even been built yet.

NASA and the European Space Agency plan to send a Martian lander and sample collection rover to the surface of Mars in 2026. The rover (our mail carrier in this extended metaphor) will roll out, gather up Percy’s tubes and place them in its mailvan — a rocket bound for Earth. Sometime in early 2030, Percy’s mail will finally reach its intended recipient, provided everything goes according to plan.

Should the mail make it home, it would be the first time humans have returned materials from another planet.

Stroke Risk Could Be Flagged Early Using Apple Watch Technology, Studies Show

The latest research shows that wearables could soon be a vital part of tracking your heart health.

For millions at risk of stroke, a simple tap on the wrist could one day save lives. New studies from the Amsterdam University Medical Center and St. Bartholomew’s Hospital in London showed that wearables, such as the Apple Watch, can improve the detection of atrial fibrillation compared to standard care. Atrial fibrillation, often referred to as A-fib, is a heart arrhythmia, which means an irregular or abnormal heartbeat. The condition can cause blood clots and is one of the leading causes of a stroke.

The Amsterdam study enrolled 437 patients aged 65 or older with elevated stroke risk and required 219 of them to wear an Apple Watch to track their heart rate for 12 hours a day for 6 months. The remaining 218 patients didn’t wear a watch and relied on standard care.

The experiment detected heart arrhythmias four times more frequently in patients wearing an Apple Watch versus those who didn’t. Specific versions of the Apple Watch use photoplethysmography, a heart rate-detecting LED light sensor, and have a built-in single-lead electrocardiogram sensor to read your heart rate.

Wearables that track heart rate and other health markers aren’t new, and previous studies have shown promise in detecting A-fib. Although wearables are known to track this type of data, no prior research has examined how well they detect potential health risks for A-fib.

«We saw that after six months we diagnosed and treated 21 patients in the group wearing the smartwatch, of whom 57% were asymptomatic,» said Michiel Winter, a cardiologist at Amsterdam UMC, in a statement. «This was against just five diagnoses in the group receiving standard care, all of whom experienced symptoms.»

The second clinical study, conducted by St. Bartholomew’s Hospital, showed that the Apple Watch could also be beneficial for detecting A-fib symptoms earlier and for monitoring patients after a standard treatment, such as a catheter ablation. The hospital found that patients could record clinical-grade ECGs on their Apple Watches at home when experiencing symptoms. Similar to the first study, the hospital found that patients using an Apple Watch detected A-fib earlier and more frequently than those receiving standard care. Catching symptoms earlier also reduces anxiousness and the likelihood that a patient will need to be hospitalized.

The findings from these studies show that wearables such as the Apple Watch could be used for long-term heart screening to detect heart health abnormalities and improve patient care for those in treatment. And it can help diagnose those who don’t know they have the condition.

«Using smartwatches with PPG and ECG functions aids doctors in diagnosing individuals unaware of their arrhythmia, thereby expediting the diagnostic process,» said Winter.

Mobile Internet Without Borders: How Verum E-SIM Is Changing the Game for Travelers and Beyond

In an era when flights take just a few hours, but data boundaries remain very real, a solution has emerged that significantly simplifies life for frequent international travelers. The Verum E-SIM app offers a next-generation virtual SIM card — no plastic, no waiting for delivery, and no traditional roaming charges.

While eSIM technology itself is no longer new, Verum takes it further: the internet works in over 150 countries worldwide under clear, uniform conditions. Connection happens through the app in just a couple of minutes — choose a package (or even a global one), pay, and activate. No need to buy local SIM cards at the airport, hunt for carrier shops, or struggle with explanations in a foreign language.

One of the biggest advantages is the complete absence of hidden fees or billing surprises. Plans are fully transparent: you immediately see how many gigabytes you get and for how long. Speed and reliability are provided by partner operators in each specific country — this isn’t a single “averaged” provider for the entire world.

Another key point for many users is that no VPN is required. As long as your device is using Verum E-SIM traffic, all familiar services and websites open directly, without extra layers or speed loss.

For those traveling with a group or family, portable Wi-Fi routers with Verum eSIM support have become a great option. One profile — and the internet is shared simultaneously across multiple smartphones, tablets, and laptops. It’s convenient on the road, in a hotel, or even in a café where the local Wi-Fi is unreliable.

Payment flexibility is also a plus: the service supports regular bank cards, cryptocurrencies, and various alternative methods — so you can choose whatever feels most convenient and cost-effective for you.

In the end, Verum E-SIM is more than just another data app. It’s a way to make mobile internet as natural and hassle-free abroad as it is at home. The difference becomes especially clear when you compare a roaming bill from one of the major operators with your Verum expenses after two or three trips.

The technology is still gaining popularity, but many travelers are already saying: “For the first time in ages, internet abroad stopped being a source of stress.” Solutions like this are shaping the future of mobile connectivity — without extra cables, borders, or unpleasant surprises.

If you travel often or simply value stable internet without unnecessary hassle — it’s worth giving it a try at least once.
