Dragonfly and the whisper of chemistry in the seas of Titan

 A Boarding Pass to Saturn

Today I'm holding a very special boarding pass. It has no seat number and no gate, but it does have a destination that, not long ago, would have sounded like something out of a Jules Verne novel: Titan, Saturn's largest moon.

My name is already on the passenger list for Dragonfly, NASA's next great mission. It will travel engraved on a small chip aboard the spacecraft, alongside the names of thousands of people from all over the world. And today I want to invite you to send yours, too.

It may seem like a small, almost symbolic gesture. But think about it for a moment: for millions of years, our species could only look up at the sky. Today we can send our names nearly a billion miles away, to a world no human will set foot on for a very long time. It's a way of saying: we were here too, looking up and asking questions.

Titan: A Strange Mirror of Earth

Titan may be the place in the solar system that most resembles Earth… and, at the same time, one of the most alien. It is the only world besides our own where we know liquids flow across the surface: it rains, rivers run, and lakes and seas fill up.

But nothing there is quite as we know it. At around −290 °F (−180 °C), water is rock, as hard as granite. What rains, flows and pools is liquid methane and ethane. The mountains are made of ice, and the dunes are made of grains of organic material.

Its atmosphere, mostly nitrogen, is thicker than ours: surface pressure is about 50% higher than on Earth. An orange haze wraps everything, created when sunlight breaks apart molecules high in the sky. From that chemistry, carbon-rich compounds slowly drift down to the ground.

That is why many scientists see Titan as a natural laboratory: a place where chemical processes similar to those on the early Earth, before life appeared, may be unfolding in slow motion and in the deep cold.

Dragonfly: An Eight-Rotor Explorer

Dragonfly is an autonomous flying vehicle with eight rotors, roughly the size of a small car. It is being built for NASA by the Johns Hopkins University Applied Physics Laboratory (APL). It will be the first mission in history designed to carry out controlled scientific flights on another world.

Paradoxically, flying on Titan is easier than flying on Earth. Its dense atmosphere gives rotors more to push against, and its gravity is only about one-seventh of ours. There, a person with wings strapped to their arms could, quite literally, fly.

Unlike Curiosity or Perseverance, which roll slowly across Mars, Dragonfly will be able to:

• Take off and land vertically.

• Fly several miles per hop between sites of scientific interest.

• Explore dunes, plains and Selk crater.

• Collect and analyze samples at many different locations.

Because sunlight on Titan is extremely faint, Dragonfly will carry a radioisotope power system that turns heat into electricity. It will recharge its batteries on the ground, between flights, during the long Titan nights.

This is how I like to describe it: Dragonfly is a blend of Ingenuity, Curiosity and Cassini, sent to one of the most exotic worlds in the solar system.

Ahmakiq Undae: “The One Who Locks Up the Wind”

Every great voyage needs a port of arrival, and Dragonfly's has just been named. In September 2026, the International Astronomical Union approved the name of the vast dune field where it will land: Ahmakiq Undae.

The name literally means “the one who locks up the wind.” It follows the tradition of naming Titan's dune fields (undae, in Latin) after wind gods and goddesses from cultures around the world; Ahmakiq comes from Maya tradition. I find it beautiful that a machine built in the 21st century will touch down on a name handed down from the ancient peoples of the Americas, who also looked up at the sky in wonder.

Ahmakiq Undae spans about 500 miles (810 km) and stretches south of Selk crater, which is about 50 miles (80 km) across. It is a region of dunes and interdune areas reaching the edge of a range of hills. From there, Dragonfly will hop toward the crater, where an ancient impact may once have mixed liquid water with organic material.

What It Seeks (and What It Doesn't)

There's something NASA itself emphasizes, and I think it's worth repeating: Dragonfly is not designed to search for life directly. Its goal is to study the chemistry that comes before biology, to better understand how the ingredients that make life possible come together.

Its goals include:

• Analyzing complex organic materials on the surface.

• Studying Titan's habitability.

• Investigating prebiotic chemistry, the path from simple molecules to ever more complex ones.

• Searching for chemical signs of environments that could be favorable to life.

I like to put it this way: while Mars helps us ask whether life could have existed somewhere else, Titan may help us understand how the chemistry began that made life possible in the first place. It is not a search for neighbors, but for our own roots.

The Itinerary

Stage	Planned date	What happens
Preparations on Earth	2026–2028	Spacecraft assembly and testing at APL; in 2026 it received its electrical wiring harness
Launch	July 2028	Liftoff aboard a SpaceX Falcon Heavy from Florida
Cruise	2028–2034	About six years crossing the solar system
Arrival	Late 2034	Atmospheric entry and landing in Ahmakiq Undae
Exploration	About 3.3 years	Flights across dunes, plains and Selk crater

If all goes according to plan, Dragonfly will be the first science rotorcraft on another world and the first aircraft to extensively explore the surface of another planet's moon. It will carry the torch from great voyagers like Viking, Cassini-Huygens and Perseverance.

Get Your Boarding Pass

NASA has opened Dragonfly's passenger list to anyone on the planet. It's free and takes just a couple of minutes:

1. Go to the mission page: science.nasa.gov/mission/dragonfly and find the section to add your name.

2. Enter your name (or your children's, your parents', your grandparents'…). It will travel engraved on a chip aboard the spacecraft.

3. Download your personalized Boarding Pass to Titan.

4. Opt in to the mission's email list. You'll join the virtual guest program and receive updates along the way.

Your Boarding Pass is only the beginning. Ahead lie the final preparations on Earth, the launch, the voyage across the solar system and the arrival. And that's when the real adventure begins.

A tip from one science communicator to you: if there are kids around, sign up with them. When Dragonfly lands in 2034, they'll be a few years older, and they'll be able to say their name reached Titan before anyone else's.

A Name, a Question, a Journey

When I look at Saturn through the telescope, Titan appears as a tiny dot beside the planet. It's hard to believe that this spark of light holds rain, rivers and dunes. And it's even harder to believe that, in a few years, a mechanical dragonfly will fly over them carrying our names.

In the end, that is what makes us human: we are not content just to look. We ask, we build, we travel, even if only through our machines. Every name on that chip is a small way of saying that exploring the cosmos doesn't belong only to scientists, but to all of us.

I already have my boarding pass. I'll see you on board. See you on Titan.

Heading Toward World of Warcraft: Forever — Introducing Astraeos Anemoi, the Scholar of the Firmament

For over two decades, I have walked across Azeroth—from the days when the shadows of the Legion burned in the sky, to the tranquil dawns along the shores of Kul Tiras. But this time, something different calls to me.

A new race rises among the clouds: the Skyborne—children of the air and heirs to the firmament. And from their ranks emerges my new character: Astraeos Anemoi, an arcane mage, a scholar of the cosmos, and a descendant of the ancient winds.

Today, I would like to formally introduce you to my new main character: Astraeos Anemoi.

Origin Story

Astraeos Anemoi. The name possesses a hidden symmetry. In Greek mythology, "Anemoi" serves as a deliberate echo of the ancient lords of the winds, while "Astraeos" evokes the Titan of the stars and winds—a harbinger of his destiny as a weaver of cosmic and celestial forces. Astraeos was born on the Isle of Zephras. Belonging to a new lineage descended from the wind-elves, his heritage was profoundly shaped by high-altitude currents and the astral energies that traverse the skies of Azeroth.

The story of Astraeos begins with the courage of his forebears. The ancestors of the Skyborne were a group of Shen'drelar High Elves from Eldre'Thalas (modern-day Feralas) who opposed their prince, Tortheldrin, in his plan to summon a demon to satisfy his addiction to magic. Fearing that this would draw the Burning Legion, they were branded traitors and forced into exile.

Thousands of years ago, these exiles—Highborne scholars who had fled with their books when the world was sundered—forged a pact with the wind elementals of Skywall. In exchange for shelter on a floating island anchored in the heavens, the winds would protect the Shen'dorei, and in return, the elves would keep the secret. Thus were born the Shen'dorei—the Skyborne—who lived in concealment for millennia.

Generation after generation, the air of Skywall transformed their people. The elders retain the pale skin of the Highborne, but among those born in recent decades, a sky-blue hue has begun to emerge—as if the heavens themselves had taken root within them. The elders call it "the dye of the pact" and debate whether it is a blessing from the elementals or the price for living among them for so long. Astraeos was one of the first children born with skin like that.

Full Biography

Astraeos evolved from a curious child into a scholar of the High Order, and from a scholar into a traveler who descended from the skies to share what he had learned.

Childhood: The Boy on the Edge

He grew up among the archives that the Highborne had salvaged from the fall of their world. While other children learned to glide using the "Walk on Air" technique, he would sit on the terraces at the edge of the island, tracking the movement of the stars with a broken astrolabe he had discovered in a storeroom. 

Training: The Geometry of the Heavens

At the age of twenty, he became an apprentice in the High Order—the branch of the Skyborne dedicated to preserving the arcane traditions of their ancestors. His masters had expected a mage of fire or frost, as those are the elements the winds most often demand; yet, Astraeos found himself drawn to the pure Arcane.

To him, arcane magic is not chaos, but the very structure of the cosmos. The orbits of the moons, the curvature of the ley lines, and the rhythm of the celestial tides all follow the same underlying proportions. A well-cast spell is, in essence, a solved equation. He learned to read the ley lines of Zephras Isle as easily as others read a map, drawing upon them to restore his own strength.

His Craft: Jewelry-Making and Enchanting

He soon discovered that starlight could be captured. Through jewelry-making, he learned to cut crystals at precise angles—initially as lenses for observing the heavens, and later as gems capable of storing energy. Through the art of enchanting, he learned to bind that energy into metal, fabric, and stone.

His rings are distinguished by a small constellation engraved on the inside—always the specific constellation that hung above the island on the night he finished the piece. He says that a gem without a piece of the sky inside is nothing more than a shiny stone.

Fishing and cooking: slow, unhurried hours

In between his observations, Astraeos fishes. He claims it is the best lesson in patience there is: a fish, much like a comet, arrives when it chooses—not when you expect it to. He cooks whatever he catches, using his mother’s recipes, and shares the meal with anyone nearby by the fire.

The descent

When the Skyborne decided to emerge from their isolation, the Council of Zephras called for volunteers to travel to the world below. Astraeos was among the first to step forward. Having spent his entire life looking upward, he finally wanted to see Azeroth from within.

Personal motto

"The wind brought me; the stars guided me."

Connection to the Alliance and Azeroth

Astraeos chose the Alliance because he found within it what he values ​​most: people who safeguard, study, and share knowledge.

Why the High Order?

When the Skyborne emerged from their isolation, each group had to make a choice. The Windshapers gravitated toward the Horde, remaining faithful to the elemental pact and the freedom of the winds. The High Order joined the Alliance to preserve their arcane traditions and the order established by their ancestors. Astraeos never wavered; he is, above all, a scholar—and knowledge requires libraries, archives, and allies to protect them.

Stormwind

This human city was his first stop. He is fascinated by its cathedrals, its library, and the faith its people place in the Light. While he does not fully share this faith, he respects it, often spending hours in conversation with priests, debating whether the cosmic order and the Light might be the same phenomenon viewed from different perspectives.

Ironforge and the Explorers' League

This serves as his second home. The dwarves of the Explorers' League study the remnants of the Titans, and Astraeos is convinced that the Titans left maps of the heavens within their ruins. He bears the name of a Titan associated with the stars—a detail he interprets as a sign. For him, Uldaman is a place of pilgrimage.

The Gnomes

He shares with them a deep passion for precision. He crafts lenses for them, while they, in turn, teach him how to construct mechanical mounts for his instruments. With their assistance, he dreams of establishing the first Skyborne observatory on solid ground.

The Night Elves: An Ancient Wound

This is his most delicate relationship. The Kaldorei remember the actions of the Highborne and remain wary of their descendants. Astraeos does not dispute this; he accepts the culpability of his forebears and strives to demonstrate, through his actions, that his people have changed. He visits Darnassus with humility and never uses arcane magic near its priestesses without first asking permission.

Dire Maul and Eldre'Thalas

In the ruins of Eldre'Thalas—known as Dire Maul—dwell the Shen'dralar, the Highborne who remained behind and from whom their own people parted ways millennia ago. To Astraeos, they are both distant kin and a cautionary tale: a glimpse of what becomes of a people who shut themselves away with their own power until they are consumed by corruption. He searches their libraries for the astronomical texts his ancestors were unable to take with them.

His Place in Azeroth

Astraeos seeks neither glory nor conquest. His purpose is to teach. Wherever he makes camp, as night falls, he gathers those who wish to listen and points out the stars—a soldier from Goldshire, a child from Stormwind, a weary dwarf. He believes that a people who learn to look upward also learn to look toward the horizon, and that this is what it means to protect a world.

Going back to the Moon isn’t the story. Staying is. NASA Artemis Update (Oct. 23, 2026)

NASA closed the week with a measured and necessary update on the path back to the lunar surface. This wasn’t an announcement designed to impress; it was the continuation of a capability the United States has maintained for more than half a century, now strengthened by new technologies, new industry partners, and a strategic urgency that simply didn’t exist during Apollo.

From Kennedy Space Center, Administrator Jared Isaacman, Associate Administrator Amit Kshatriya, and Artemis Program Manager Jeremy Parsons outlined the plan: Artemis III will fly in the summer of 2027, and Artemis IV aims to return astronauts to the lunar surface in 2028. These dates are ambitious, but not arbitrary. They reflect a moment in which lunar exploration is no longer symbolic — it is a domain where technological, industrial, and scientific leadership is actively contested.

Artemis III will send four astronauts to low Earth orbit for a 14‑day (extendable to 17) mission to practice docking Orion with two commercial test landers: Blue Moon and Starship. For those of us who remember milestones like the SAFER system in the 1990s, the Space Station Freedom designs, or the first flying robots on Mars, this phase may seem less dramatic. But it is decisive: this is where the systems that enable safe, repeatable operations beyond Earth orbit are validated.

Meanwhile, the hardware is moving forward. Inside the Vehicle Assembly Building, the core stage of the Space Launch System is being integrated with the already‑stacked solid rocket boosters. Processing timelines have tightened thanks to more direct decision‑making and an engineering culture focused on solving problems in the shop rather than in committees. A wet dress rehearsal is planned in the coming months — a critical step before flight.

Artemis IV, targeted for 2028, remains the first crewed landing of this new era. NASA is keeping options open with both landing partners and refining requirements for the early missions: lighter sortie‑style spacesuits, an extended Centaur upper stage to bring Orion closer to the Moon, and adjusted orbital profiles. Before the crewed landing, uncrewed demonstrations and propellant transfer tests will take place in orbit.

Integration continues in parallel: SLS stacking at KSC, Starship’s propellant transfer tests, and the preparation of Blue Origin’s Mark 1 and Mark 2 landers. All of this unfolds while China advances steadily toward its own crewed lunar landing. This is not a race for spectacle — it is a race for capability.

For those of us who grew up watching SAFER on television, studying the Freedom station designs, or following the first flying robots on Mars, know that space exploration has never been static. Artemis is not trying to repeat Apollo; it is trying to build what Apollo never could — a sustained human presence. And that requires discipline, not astonishment. As Isaacman reminded us, no amount of enthusiasm changes the laws of physics. That is precisely why each of these tests matters.

Space exploration reaches maturity when it moves past short-lived spectacle and focuses on solving the hard engineering challenges of deep space operations. The true significance of this moment isn't the show—it's the sheer scale of the machine being put into motion.

Upcoming milestones to watch: New Glenn’s return to flight, Starship’s 15th test mission, and the SLS wet dress rehearsal. I’ll be sharing updates as they come.
