NASA’s Psyche spacecraft rocketed away Friday on a six-year journey to a rare metal-covered asteroid.

Most asteroids tend to be rocky or icy, and this is the first exploration of a metal world. Scientists believe it may be the battered remains of an early planet's core, and could shed light on the inaccessible centers of Earth and other rocky planets.

SpaceX launched the spacecraft into an overcast midmorning sky from NASA’s Kennedy Space Center. Named for the asteroid it’s chasing, Psyche should reach the huge, potato-shaped object in 2029.

“It's so thrilling,” said Laurie Leshin, director of NASA’s Jet Propulsion Laboratory. Added Arizona State University's Jim Bell, part of the Psyche team: “What a great ride so far.”

After decades of visiting faraway worlds of rock, ice and gas, NASA is psyched to pursue one coated in metal. Of the nine or so metal-rich asteroids discovered so far, Psyche is the biggest, orbiting the sun in the outer portion of the main asteroid belt between Mars and Jupiter alongside millions of other space rocks. It was discovered in 1852 and named after Greek mythology’s captivating goddess of the soul.

“It’s long been humans’ dream to go to the metal core of our Earth. I mean, ask Jules Verne,” lead scientist Lindy Elkins-Tanton of Arizona State University said ahead of the launch.

“The pressure is too high. The temperature is too high. The technology is impossible,” she said. “But there’s one way in our solar system that we can look at a metal core and that is by going to this asteroid.”

Astronomers know from radar and other observations that the asteroid is big — about 144 miles (232 kilometers) across at its widest and 173 miles (280 kilometers) long. They believe it’s brimming with iron, nickel and other metals, and quite possibly silicates, with a dull, predominantly gray surface likely covered with fine metal grains from cosmic impacts.

Otherwise, it’s a speck of light in the night sky, full of mystery until the spacecraft reaches it after traveling more than 2 billion miles (3.6 billion kilometers).

Scientists envision spiky metal craters, huge metal cliffs and metal-encrusted eroded lava flows greenish-yellow from sulfur — “almost certain to be completely wrong,” according to Elkins-Tanton. It's also possible that trace amounts of gold, silver, platinum or iridium — iron-loving elements — could be dissolved in the asteroid's iron and nickel, she said.

“There's a very good chance that it’s going to be outside of our imaginings, and that is my fondest hope," she said.

Believed to be a planetary building block from the solar system’s formation 4.5 billion years ago, the asteroid can help answer such fundamental questions as how did life arise on Earth and what makes our planet habitable, according to Elkins-Tanton.

On Earth, the planet's iron core is responsible for the magnetic field that shields our atmosphere and enables life.

Led by Arizona State University on NASA’s behalf, the $1.2 billion mission will use a roundabout route to get to the asteroid. The van-size spacecraft with solar panels big enough to fill a tennis court will swoop past Mars for a gravity boost in 2026. Three years later, it will reach the asteroid and attempt to go into orbit around it, circling as high as 440 miles (700 kilometers) and as close as 47 miles (75 kilometers) until at least 2031.

The spacecraft relies on solar electric propulsion, using xenon gas-fed thrusters and their gentle blue-glowing pulses. An experimental communication system is also along for the ride, using lasers instead of radio waves in an attempt to expand the flow of data from deep space to Earth. NASA expects the test to yield more than 10 times the amount of data, enough to transmit videos from the moon or Mars one day.

The spacecraft should have soared a year ago, but was held up by delays in flight software testing attributed to poor management and other issues. The revised schedule added extra travel time. So instead of arriving at the asteroid in 2026 as originally planned, the spacecraft won’t get there until 2029.

That’s the same year that another NASA spacecraft — the one that just returned asteroid samples to the Utah desert — will arrive at a different space rock as it buzzes Earth.



Penguin Memes Take Flight after Trump Tariffs Remote Island

Penguin Memes Take Flight after Trump Tariffs Remote Island

Donald Trump's tariffs have become a black and white issue on social media, where penguin memes have gone viral after he targeted an island inhabited by the flightless birds, but no people.

One widely shared image on Thursday showed a penguin in place of Ukrainian leader Volodymyr Zelensky in the Oval Office during his recent row with the US president and Vice President JD Vance.

Another meme showed US First Lady Melania Trump gazing up at an emperor penguin -- in place of former Canadian Prime Minister Justin Trudeau -- while Trump looks askance.

Trump's announcement of worldwide tariffs on Wednesday certainly received an icy reception in many countries.

But there has also been bafflement about why some of the most remote parts of the world have been targeted.

A case in point: why would Trump slap 10 percent tariffs on all exports from the Heard and McDonald Islands, a barren sub-Antarctic Australian territory without a human population, but four different species of penguin?

"The penguins have been ripping us off for years," Anthony Scaramucci, who was Trump's former communications chief for 11 days in his first term and is now a vocal critic, joked on X.

"Donald Trump slapped tariffs on penguins and not on Putin," posted US Senate Democratic leader Chuck Schumer, referring to the fact that Russia was not on the US tariff list.

The White House said sanctions on Russia over President Vladimir Putin's war on meant that there was no "meaningful" trade on which to impose tariffs.

Trump also caused puzzlement with his 29 percent tariff on Norfolk Island, a tiny Australian territory in the Pacific with a population of a little over 2,000 humans.

"I'm not quite sure that Norfolk Island, with respect to it, is a trade competitor with the giant economy of the United States," Australian Prime Minister Anthony Albanese said.

Britain's remote Falkland Islands -- home to one million penguins, and most famous for a 1982 war fought by Britain to repel Argentinian invaders -- was hit by 41 percent exports even though the UK only faces 10 percent.

Trump's tariffs have however been no laughing matter for global markets, with US stocks suffering their worst day since the Covid pandemic in 2020.
