CAPE CANAVERAL, Fla. (AP) — NASA’s newest crown jewel blasted off Sunday to hunt for planets around other stars, explore secret dark energy and survey the cosmos like never before.

SpaceX launched the $4.3 billion Roman Space Telescope shortly after daybreak aboard a triple-the-firepower Falcon Heavy rocket. Roman blazed toward an observation point 1 million miles (1.6 million kilometers) away that’s home to the Webb Space Telescope, one of NASA’s other big-ticket eyes in the sky.

The bus-sized telescope — named after the late Nancy Grace Roman, NASA’s first chief astronomer — will take more than three months to reach its destination. Once there, it will cast the widest gaze yet on the hidden parts of the universe from space, uncovering the unimaginable with unsurpassed speed.

“It’s going to find thousands of supernovae, tens of thousands of planets, billions of galaxies and tens of billions of stars,” said NASA science mission director Nicky Fox. “It’s going to be able to do things that we’ve never been able to do before with its massive field of view.”

3… 2… 1… Liftoff! And a call from the president

Several minutes after the thunderous launch from Kennedy Space Center, the rocket’s two reusable side boosters descended tail-first in a thrilling scene, producing sharp sonic booms as they landed back at Cape Canaveral. Soon afterward, the telescope separated successfully from the rocket’s upper stage, drawing applause from ground controllers.

Fox was in tears watching the action unfold. “It’s such a good day!” she said.

NASA Administrator Jared Isaacman was in the middle of a news conference a couple hours later, predicting that the Roman Space Telescope would soon become a household name, when his cellphone rang. President Donald Trump was on the line, offering congratulations.

“Boy, it looked beautiful on television,” said Trump, fresh off his visit to Houston’s Johnson Space Center on Friday to honor the Artemis II moon crew. “You’re the hottest in space.”

Roman Space Telescope will provide a wider perspective

Roman’s field of view is more than 100 times wider than that of NASA’s Hubble Space Telescope, still churning out celestial glamour shots after 36 years in orbit. Webb joined the effort several years ago with an even narrower yet spot-on vision capable of zooming in on objects almost as old as the universe-creating Big Bang.

These three orbiting powerhouses will join forces — along with the European Space Agency’s Euclid spacecraft and the National Science Foundation’s Vera C. Rubin Observatory in Chile — to reveal some of the universe’s biggest secrets.

Inside the countless galaxies awaiting discovery are stars with planets. Once these new worlds are spotted by Roman, the more powerful and sensitive Webb will take aim to fill in the blanks.

“Roman’s vast reach will allow us to find the weird, the rare and the unusual,” senior project scientist Julie McEnery said on the eve of launch. “We’ll redefine what it means to find a needle in a haystack.”

Perhaps even more important, astronomers expect Roman to shed light on the dark matter and dark energy that make up most of the universe yet remain concealed. Roman’s catalog of galaxies will help scientists ascertain how quickly the universe is expanding due to these puzzling, unseen forces.

Roman will scan the sky 1,000 times faster than Hubble

Roman’s superpower is speed.

A month of Milky Way observations by Roman would take Hubble a century to complete, according to McEnery. Roman should make quick work of scanning the galactic bulge at dead center, she added, providing the deepest look yet into the heart of our galaxy.

Besides a wide-field infrared camera that matches Hubble’s sensitivity but is 1,000 times faster, Roman holds an instrument to block out starlight. This experimental, eclipse-creating coronagraph will allow Roman to directly image any planet, however faint, that might be orbiting the masked star.

While Roman isn’t designed to search for life, Fox said it will pave the way for future observatories to answer what NASA considers the biggest question: “Are we alone? Is there another Earth 2.0 looking back at me?”

The telescope is designed to be refueled, meaning if a robotic tanker becomes available in the coming decade, that could extend its life.

The telescope’s mirror has a surprising origin

Launching nearly a year ahead of schedule and within budget, Roman is NASA’s first space telescope to be named after a woman.

Retired NASA scientist Ed Weiler said the honor is long overdue. He coined the phrase “Mother of Hubble” for Roman, who hired him in 1978. Observatories above Earth’s obscuring atmosphere can see farther and better, she insisted after joining the brand new NASA in 1959. She died in 2018 at age 93.

“This is very, very fitting. I think Nancy would be very proud” that the namesake telescope will tackle some of the biggest, lingering questions about the universe such as dark energy, Weiler said.

Hubble launched in 1990 with a flawed mirror that required spacewalking astronauts’ dramatic intervention. Roman’s primary mirror is the same size as Hubble’s — nearly 8 feet (2.4 meters) in diameter — and is actually spy satellite surplus.

The National Reconnaissance Office donated two leftover mirrors to NASA more than a decade ago for repurposing. The second mirror is still in storage.

WASHINGTON (AP) — President Donald Trump said Thursday he is renaming Lake Ontario to be known as “Lake America” in the United States as he escalates his trade war with Canada.

The Republican president signed an executive order directing the Interior Department to update the lake’s name in the U.S. geographic naming service. Trump cannot force Canada to follow along, however.

Trump has been floating the idea of the name change in recent days as the U.S. announced it was imposing 50% tariffs on $20 billion worth of Canadian goods over the weekend after talks between the countries broke down. Trump has been needling America’s northern neighbor since he returned to the White House last year, suggesting the ally with whom the U.S. once had warm relations should instead be absorbed as the 51st state.

Canada responded to Trump’s import taxes this week by imposing retaliatory tariffs on $20 billion worth of American goods, including steel, dairy products, appliances and farm equipment.

Trump, who signed the order as he was sitting at the Resolute Desk in the Oval Office, had a large sign behind him propped on a stand with a map of the Great Lakes. Over Lake Ontario, in big red letters, the map read “Lake America.”

On the other side of the president was another map with the words, “MAKING THE GREAT LAKES EVEN GREATER.”

Trump said as he was signing the order that he’d “notified all of the various people that we have to notify. So, we’ve done everything that you have to do.”

“And this is official, effective immediately,” he added.

But the executive order Trump signed shows that the changes are supposed to be made within 30 days.

Canadian officials dismissed Trump’s move.

Canadian Prime Minister Mark Carney rejected the move, invoking the lake’s Indigenous roots and noting that the name predates both Canadian Confederation and the U.S. Declaration of Independence.

“Canadians also know that naming reality means calling it Lake Ontario — then, now and always,” he wrote.

Ontario Premier Doug Ford, who has traded insults with Trump, said on X: “It’s Lake Ontario to Canadians and the rest of the world. Now and forever.”

Nova Scotia Premier Tim Houston said, “We’re into some real foolishness now. It’s Lake Ontario, buddy.”

The lake is one of multiple Great Lakes that the U.S. and Canada share borders along. New York Gov. Kathy Hochul, a Democrat whose state shares a border on the lake, wrote on X in response to the White House’s announcement that, “New York won’t be calling it that.”

There is no single international body that determines names of international bodies of water and Trump has wide latitude over how the U.S. government recognizes geographic places and landmarks.

The name Lake Ontario comes from the Huron Indigenous people’s word “oniatarí:io,” which means “lake of shining waters.” The province of Ontario, founded in 1867, took its name from the lake.

Trump said that while his action was not meant to send any particular geopolitical message, “Canada’s been ripping us off for a long time” on trade and military issues.

“They wanted to be treated like a state and they’re not a state,” the president said. “We just can’t do that anymore.”

“We love the people of Canada,” Trump added. “I don’t think their representatives do, an appropriate job. Maybe they’ll change. I really don’t know. It doesn’t make much difference.”

The move is reminiscent of his move last year to rename the Gulf of Mexico as the “Gulf of America.”

Trump scribbled his name with a Sharpie pen on the executive order, then held it up for the cameras, offering, “And we filed all the necessary papers, documents, everything else.”

He also suggested his push to rename bodies of water may not be finished.

“So, if you think about it, we have a gulf and we have a lake. Now, all we need is an ocean,” Trump said. “So maybe we’ll have to change the name of the Atlantic and/or the Pacific. Maybe we’ll change them.”
