SpaceX made a key milestone in delivering global internet connectivity on April 24, 2025, with the successful launch of the Starlink 6-74 mission. In the mission, 28 satellites were deployed in low Earth orbit, adding further to Spacex’s Starlink constellation. This expansion is central to the company’s mission of providing high-speed internet connectivity to even the most distant and underserved parts of the globe. With every successful deployment, SpaceX is incrementally moving closer to its vision of delivering low-latency, reliable internet to millions of individuals around the world, improving connectivity in rural communities.

SpaceX Falcon 9 launched Starlink satellites from Cape Canaveral

The rocket launched at 9:52 pm ET from Launch Complex 40 (LC-40) at Florida’s Cape Canaveral Space Force Station. The Falcon 9 rocket blasted into the evening sky, accelerated by nine Merlin engines in its initial stage. The successful launch is another milestone for SpaceX as it inches nearer to finishing its ambitious Starlink megaconstellation.
Within the nose fairing of the rocket, a neatly stacked array of 28 Starlink satellites was securely fastened. The satellites are intended to reach low Earth orbit (LEO), where they will deliver high-speed internet to large regions around the globe. As part of the expanding Starlink constellation, these satellites will improve global connectivity, especially in remote and underserved communities, by providing low-latency, reliable broadband services.

SpaceX booster successfully lands after 23rd flight, satellites deployed in orbit

Around 2.5 minutes into flight, the first stage of the rocket—a booster named B1069—finished burning its main engines and jettisoned itself from the top stage. This booster has quite a good history. The April 24 flight was its 23rd, which makes it one of the most reused Falcon 9 boosters to have flown so far.
Upon separation, B1069 started its descent to Earth. Approximately six minutes after that, it made a spot landing on the droneship “A Shortfall of Gravitas,” which was docked in the Atlantic Ocean. This was the 19th Starlink mission for B1069 and yet again highlighted the efficiency and affordability of SpaceX’s reusable rocket system. As the booster landed safely back on Earth, the Falcon 9 upper stage continued to ascend. Having the payload of 28 satellites, it entered low Earth orbit and ultimately deployed the satellites an hour after launch. From there, individual satellites will employ onboard thrusters to move into final orbit, joining the larger Starlink constellation.

SpaceX achieves record-breaking launch milestones in 2025

The Starlink 6-74 mission was not just another success of deployment—it was also SpaceX’s record-breaking year. The company’s 47th Falcon 9 launch of 2025 and its 30th Starlink-specific mission in 2025, this mission made it into the history books. This staggering rate indicates SpaceX’s industrial and logistical prowess, allowing it to take over the space launch market.
The reuse capability of boosters such as B1069 is the key to this fast pace. Reusability is key to lowering the cost of launches and making frequent launches feasible, which makes SpaceX all the more different from the rest.
Space enthusiasts and photographers flocked to places like Woodside Park in Viera, Florida, to take awe-inspiring pictures of the liftoff. Powerful lenses captured the rocket’s blazing climb, stage separation, and even the landing burn on the droneship. The mission’s visibility in the evening sky was a spectacle for skywatchers and only served to boost public interest in space exploration.

Future of Starlink and SpaceX’s broader vision

With thousands of satellites already in orbit, Starlink is set to be a global internet infrastructure leader. The network has already demonstrated potential in increasing rural and remote communities’ connectivity. As the constellation expands, Starlink is likely to bring faster speeds, wider coverage, and higher reliability—rivaling traditional ISPs.

In a groundbreaking discovery, scientists in Brazil have discovered the world’s oldest known ant fossil of a 113-million-year-old specimen of a fearsome predator known as a “hell ant.” Unearthed from limestone in northeastern Brazil, this fossil dramatically reshapes our understanding of ant evolution, pushing back their known history by over 13 million years. Published in Current Biology, the study reveals that ants were already diverse and widespread during the time of dinosaurs. With scythe-like jaws used to impale prey, this ancient insect highlights how complex and specialised ants were, even in their earliest forms.

What are hell ants

Hell ants are an extinct subfamily of ants known scientifically as Haidomyrmecinae. They lived during the Cretaceous period, between 145 and 66 million years ago. What makes them especially fascinating is their unique jaw structure: instead of moving side to side like modern ants, their scythe-shaped jaws curved upward and were likely used to impale or pin down prey. This brutal hunting method gives them their dramatic nickname.
These ants are among the most anatomically distinct ever discovered and are considered one of the most intriguing ant groups in evolutionary history.

What does the 113-year-old hell ant fossil reveal

The newly discovered fossil is a winged female ant, possibly a queen, and was found in limestone deposits from the Crato Formation in northeastern Brazil. It has been named Vulcanidris cratensis, combining “Vulcano,” the name of the family who donated the rock, and “idris,” a suffix commonly used in ant taxonomy meaning “the provident one.”
At 113 million years old, the fossil predates the previously oldest known ant specimens, found in amber in Myanmar and France, by approximately 13 million years.

How scientists peek into the fiery preying technique of hell ants

Lead researcher Anderson Lepeco and his team at the Museu de Zoologia da Universidade de Sao Paulo used a high-resolution 3D imaging technique called micro-computed tomography to examine the fossil trapped in limestone. This allowed scientists to study the insect’s internal structures, particularly its jaws, in extraordinary detail. when a small insect came close, the hell ant would quickly snap its jaws shut in an upward motion, trapping the prey against its horn. This action would pierce or pin the prey in place, like a fork stabbing food against a plate.
This style of attack was very different from modern ants, whose jaws usually move side to side. Hell ants’ upward-striking jaws gave them an evolutionary edge in ambushing and killing prey.
“When I started to look at it and compared it to fossils from Myanmar, I was just shocked,” said Lepeco. “I was very, very excited. I was jumping through the lab.”

The incredible world of ants

Ants have fascinated scientists for decades, not only because of their ancient origins but also due to their incredible capabilities today. These tiny insects are among the most ecologically dominant animals on Earth, with an estimated population of nearly 20 quadrillion. Found on every continent except Antarctica, that’s about 2.5 million ants for every human on the planet.
They are known for their complex social organisation, advanced communication systems, and even medical skills. Some species can perform amputations to save wounded nestmates. Others can be trained to use their keen sense of smell to detect diseases such as cancer. Their sex lives and reproductive strategies also surprise researchers, making ants a truly remarkable group in the animal kingdom.

Why this discovery matters

The fossil offers the earliest undisputed evidence of ants in South America and pushes back the known presence of ants on the continent by over 60 million years. According to Corentin Jouault, an evolutionary biologist at the University of Oxford, this is a breakthrough in paleomyrmecology, the study of ancient ants. It also supports the theory that ants were already widespread during the time of Gondwana, the ancient supercontinent that included present-day South America, Africa, India, and other landmasses.

What lies ahead

Scientists now plan to expand their research by building a larger database of ancient ant fossils to better understand how ants evolved. This discovery also highlights the importance of museum collections, as the fossil was found in rocks that had been stored for years, unnoticed.
As researchers continue to explore both field sites and forgotten drawers in collections, the fiery story of hell ants serves as a reminder that some of Earth’s most historic secrets are still waiting to be uncovered.
