The Most Powerful Rocket in History Had a Good Morning

SpaceX has once again launched the most powerful rocket in history into the sky, and this time, the mission seems to have passed most of its key milestones. Starship took off without a hitch this morning, separated from its booster, and cruised through space for a while before SpaceX lost contact with it. Instead of splashing down in the ocean as planned, Starship seems to have been destroyed during reentry in Earth’s atmosphere.

The Oceans We Knew Are Already Gone

Even after nearly three months of winter, the oceans of the Northern Hemisphere are disturbingly warm. Last summer’s unprecedented temperatures—remember the “hot tub” waters off the coast of Florida?—have simmered down to a sea-surface average around 68 degrees Fahrenheit in the North Atlantic, but even that is unprecedented for this time of year. The alarming trend stretches around the world: 41 percent of the global ocean experienced heat waves in January.

Another ‘Rapid Unscheduled Disassembly’ for Elon Musk

The second liftoff of Starship, SpaceX’s giant new rocket-and-spaceship system, went beautifully this morning, the fire of the engines matching the orange glow of the sunrise in South Texas. The spaceship soared over the Gulf Coast, with all 33 engines in the rocket booster pulsing. High in the sky, the vehicles separated seamlessly—through a technique that SpaceX debuted during this flight—and employees let out wild cheers.

You’ve Never Seen a Star Like This

From our perspective down here, on the surface of our planet, the stars are tiny, gleaming specks in an inky-dark universe. Occasionally they appear to twinkle, when the air in our atmosphere bends the incoming light. Through telescopes, they are balls of light, their glow distorted by the lens. And up close, the best star in the universe—our sun—is an orangey sphere of flame.But stars can be so much more than that, as telescopes, especially the very good ones, can reveal.

This Hurricane Season Is Unprecedented

Updated at 5:29 p.m. on August 31, 2023Earlier this week, mission control commanded the International Space Station to turn its cameras toward the Gulf of Mexico. Giant white clouds, gleaming against the blue of the planet’s oceans and the blackness of space beyond, indicated the arrival of Hurricane Idalia, hovering menacingly off the coast of Florida.

The Most Believable Reality TV Is Set on Mars

The astronauts arrived at the Mars base one by one, dressed in faded orange spacesuits. After they walked through a pressurized chamber and removed their helmets, they were blasted in the face with some sort of decontaminating mist. When the cyclist Lance Armstrong walked in, one of his comrades was in awe. “The fact that we have an astronaut is so crazy,” Ariel Winter, an actor who appeared on Modern Family, told another contestant, who was visibly confused.

Black Holes Swallow Everything, Even the Truth

In 1967, the physicist John Wheeler was giving a lecture about a mysterious and startling phenomenon in deep space that the field was just beginning to understand. But it didn’t have a great name to match. Wheeler and his audience were equally tired of hearing “gravitationally completely collapsed object” over and over, so someone threw out an idea for a different name. A few weeks later, at another conference, Wheeler debuted the suggestion: black hole.

UFOs Are Officially Mainstream

Earlier today, three witnesses came before Congress to testify about their experiences with unidentified flying objects. A former Navy pilot spoke of the mysterious objects that he has seen with his own eyes and through radar, and how frequently pilots encounter them in the air. A retired Navy commander described the time he pulled his jet up to a Tic Tac–shaped object hovering over the ocean, then watched it suddenly speed up and vanish.

Earth Is a Potato

Earth, in most renderings, is a smooth sphere with a glossy complexion—a blue marble, as pictures snapped from space have shown us. Earth scientists know that’s not exactly true. Earth, in fact, is an ellipsoid, a little bit squashed at the poles and fat around the equator, not to mention speckled with mountain ranges. And then you have the geoid people—the ones who think of Earth less as an imperfect sphere and more as a lumpy potato.C. K.

How Could This Have Happened?

The dreadful saga of the missing Titanic submersible is finally drawing to a close. On Sunday, the vessel, called the Titan, was supposed to take five people on an hours-long, 12,500-foot-deep journey to the wreckage of the Titanic, which rests at the bottom of the Atlantic Ocean. Instead, less than two hours into the tour, the submersible lost contact with its support ship. At a press conference this afternoon, the U.S.

The Titanic Sub and the Enduring Appeal of Extreme Tourism

The submersible craft’s journey to the bottom of the ocean and back was supposed to take about eight hours. Two and a half hours for the descent, a few hours to explore the century-old wreckage of the Titanic, and then another two and a half hours to return to the surface.But the sub and its five passengers have now been missing in the Atlantic Ocean for three days. In that period, it has had no communication with the rest of the world.

Why Everyone Is Suddenly Talking About Aliens

If ever a headline has demanded a wide-eyed, scrambling-to-click reaction, it might be this one: “Intelligence Officials Say U.S. Has Retrieved Craft of Non-human Origin.”A website called The Debrief—which says it specializes in “frontier science” and describes itself as self-funded—reported this week that a former intelligence official named David Grusch said that the U.S.

Not Your Grandfather’s Moon Mission

If you asked Americans to name a space mission, any space mission, I suspect very few would pick Apollo 8. The 1968 mission, the first to circle the moon, gets overshadowed by Apollo 11 (“One small step for man”; you know the rest) and Apollo 13 (of Tom Hanks fame). The astronauts didn’t venture from their spaceship, nor did they touch the lunar surface. But in its own, quiet way, that mission was an existential milestone.

The Search for Earth Look-alikes Is Getting Serious

Updated at 5:30 p.m. ET on March 29, 2023.Several years ago, astronomers pointed a telescope at another star and discovered something remarkable: seven planets, each one about the same size as Earth. The planets were quite close to their small star—all seven of their orbits would fit inside Mercury’s.

Elon Musk Is Spiraling

In recent memory, a conversation about Elon Musk might have had two fairly balanced sides. There were the partisans of Visionary Elon, head of Tesla and SpaceX, a selfless billionaire who was putting his money toward what he believed would save the world. And there were critics of Egregious Elon, the unrepentant troll who spent a substantial amount of his time goading online hordes. These personas existed in a strange harmony, displays of brilliance balancing out bursts of terribleness.

Astronomers Were Not Expecting This

Humans have long found meaning in the stars, but only recently have we begun to understand whole clusters of them—galaxies, way out in the depths of space. A few nearby galaxies, such as Andromeda, have always been visible to the naked eye as a dusky smear in the night sky.

A New Age of UFO Mania

In May 1957, an American fighter pilot stationed in the quiet English countryside was suddenly ordered to get into the air and shoot down an unidentified flying object. The pilot, Milton Torres, pursued the target, which appeared motionless at times before zooming at thousands of miles per hour. He locked on to the object and prepared to fire, but it vanished from radar screens.

The Chinese Balloon and the Disappointing Reality of UFOs

Residents of Billings, Montana, encountered a rather strange sight this week: A giant white ball hovering in the sky in broad daylight. The ball drifted between clouds and shimmered in the sun. It looked almost like a second moon.American military officials suspect that the floating mystery object is a Chinese spy balloon. The high-altitude object, they say, traveled from China to Alaska and then Canada before crossing into the continental United States. The U.S.

The Existential Wonder of Space

Illustrations by Daniele CastellanoOf all the moons in the solar system, Saturn’s largest satellite might be the most extraordinary. Titan is enveloped in a thick, hazy atmosphere, and liquid methane rains gently from its sky, tugged downward by a fraction of the gravity we feel on Earth. The methane forms rivers, lakes, and small seas on Titan’s surface. Beneath the frigid ground, composed of ice as hard as rock, is even more liquid, a whole ocean of plain old H2O.

Asteroid Measurements Make No Sense

A couple of newly discovered asteroids whizzed past our planet earlier this month, tracing their own loop around the sun. These two aren’t any more special than the thousands of other asteroids in the ever-growing catalog of near-Earth objects. But a recent news article in The Jerusalem Post described them in a rather eye-catching, even startling, way: Each rock, the story said, is “around the size of 22 emperor penguins stacked nose to toes.

There’s Snow on Mars

Noora Alsaeed has often thought about building a snowman on Mars.Let’s go over that again. A snowman on Mars? That desertlike, desolate planet over there? The one covered in sand? What an unusual daydream.But Alsaeed knows a few things that the rest of us don’t. She is a planetary scientist at the University of Colorado at Boulder whose work relies on data from a NASA spacecraft that orbits Mars.

Our Strange New Era of Space Travel

In December of 1972, astronaut Eugene Cernan left his footprints and daughter’s initials in the lunar dust. In doing so, he became the last man to set foot on the moon. Now, after 50 years, humanity is going back. But in the half-century since Apollo 17, a lot has changed in how we explore space—and how we see our place in it.While those early missions were all run by governments, much of modern spaceflight is the domain of billionaires and their private companies.

If You Must Cry Over a Space Robot, Make It This One

Here is the happy part: For more than four years, a funky-looking spacecraft did something remarkable. It was in many ways just another robot, a combination of hardy materials, circuits, and sensors with a pair of solar panels jutting out like wings on an insect. But this particular robot has listened to the ground shake on Mars. It has felt marsquakes beneath its little mechanical feet.NASA and European space agencies designed the spacecraft to study these Martian quakes in detail.

The Luckiest Rover

The Mars rover was out and about, doing its normal rover things inside one of the red planet’s craters, when there was a sudden shift in the atmosphere. A vortex of air and dust had swirled into shape, and it was fast approaching. The rover, named Perseverance, didn’t move from its spot. The whirlwind slammed into the robot, tiny particles pinging its exterior. Within seconds, the bombardment was over, and the vortex was gone.Perseverance was fine.

NASA’s Plan to Bounce People Off the Atmosphere

Updated at 2:37 p.m. ET on December 11, 2022If you want to send people to the moon, you have to be able to bring them home safely. And if you want to bring them home, you must send them hurtling through Earth’s atmosphere in a wash of heat and fire.An incoming capsule exits space at thousands of miles per hour, then decelerates rapidly. The astronauts inside feel gravity reassert itself with an uncomfortable crush.

The Russian Space Program Is Falling Back to Earth

The new crew arrived at the International Space Station last week, all smiles and floating hair. There was, as usual, a little welcome ceremony, with heartfelt remarks from the newcomers streamed live for the people they left behind on Earth. A few of the astronauts floated above the others and turned upside down, hanging like bats, so that their beaming faces would fit into the frame.

Well That’s One Way to Save a Space Telescope From Falling Back to Earth

The Hubble Space Telescope is falling.Not imminently, but it’s happening. The beloved observatory, which has spent decades revealing cosmic wonders from its perch a few hundred miles above Earth, does not have a propulsion system to maintain its altitude. According to NASA’s latest projections, the observatory could reenter Earth’s atmosphere as early as 2037—a grim fate that the agency has been anticipating for many years.

Maybe We Won’t End Up Like the Dinosaurs

The space probe came barreling in at thousands of miles per hour, its mechanical eyes locked on its target—an asteroid named Dimorphos.About an hour out, the asteroid looked to the probe’s cameras like nothing more than a faint speck in the darkness of space, slightly larger than a single pixel on your screen. A few minutes out, it began to look distinctly asteroid-like, lumpy and gray.

This Is Neptune?

Did you know that Neptune has rings?It’s true. The planet we’re now told is the farthest from us has a set of narrow bands made of dust. Planetary scientists know this, as do hard-core astronomy fans, probably. But for those of us who have certain textbook images of the solar system in our mind, the knowledge that Neptune is a ringed planet might come as a surprise.

A Gnarly New Theory About Saturn’s Rings

Saturn has quite the collection of moons, more than any other planet in the solar system. There’s Enceladus, blanketed in ice, with a briny ocean beneath its surface. There’s Iapetus, half of which is dusty and dark, and the other shiny and bright. There are Hyperion, a rocky oval that bears a striking resemblance to a sea sponge, and Pan, tiny and shaped just like a cheese ravioli.But one moon might be missing.
