Geoff Brumfiel

Geoff Brumfiel works as a senior editor and correspondent on NPR's science desk. His editing duties include climate and environment, while his reporting focuses on the intersection of science and national security.

From April of 2016 to September of 2018, Brumfiel served as an editor overseeing basic research and climate science. Prior to that, he worked for three years as a reporter covering physics and space for the network. Brumfiel has carried his microphone into ghost villages created by the Fukushima nuclear accident in Japan. He's tracked the journey of highly enriched uranium as it was shipped out of Poland. For a story on how animals drink, he crouched for over an hour and tried to convince his neighbor's cat to lap a bowl of milk.

Before NPR, Brumfiel was based in London as a senior reporter for Nature Magazine from 2007-2013. There, he covered energy, space, climate, and the physical sciences. From 2002 – 2007, Brumfiel was Nature Magazine's Washington Correspondent.

Brumfiel is the 2013 winner of the Association of British Science Writers award for news reporting on the Fukushima nuclear accident.

Today in Saudi Arabia, Secretary of State Mike Pompeo left no wiggle room. He said he knows exactly who was behind last weekend's attack on two Saudi oil facilities.

(SOUNDBITE OF ARCHIVED RECORDING)

MIKE POMPEO: I think it's abundantly clear, and there is an enormous consensus in the region that we know precisely who conducted these attacks was Iran.

SHAPIRO: Iranian Foreign Minister Javad Zarif called those accusations false in a CNN interview.

(SOUNDBITE OF ARCHIVED RECORDING)

On Sept. 14, a major Saudi oil processing plant was rocked by a series of explosions. The facility, and another oil field to the south, had been attacked from the air. Here's what we know — at this time — about the attacks based on physical evidence.

The strike was large and sophisticated

On the face of it, NASA's newest probe sounds incredible. Known as Dragonfly, it is a dual-rotor quadcopter (technically an octocopter, even more technically an X8 octocopter); it's roughly the size of a compact car; it's completely autonomous; it's nuclear powered; and it will hover above the surface of Saturn's moon Titan.

Iran almost certainly had some role in a major attack on an oil production facility in Saudi Arabia, according to independent analysts reviewing the available evidence.

The question is how big.

The attack came on Sept. 14. Multiple drones or missiles struck Saudi Aramco's Abqaiq facility, causing massive damage and crippling the nation's oil production. The production of 5.7 million barrels of crude oil per day had to be suspended, according to the company.

A major oil storage terminal on Grand Bahama Island was damaged by Hurricane Dorian and has leaked oil into the surrounding environment, raising concern that the oil could damage local reefs and wildlife.

The South Riding Point facility sits on the shore of the island's eastern side and is home to 10 giant storage tanks capable of holding up to 6.75 million barrels of crude, according to Equinor, the company that runs the facility.

The first thing Melissa Hanham did when she saw President Trump's tweet last week was take a screen grab.

"My reaction was to immediately save the image to my phone just in case it got taken down," she says.

The wording on the tweet was cryptic: "The United States of America was not involved in the catastrophic accident during final launch preparations for the Safir [space launch vehicle] Launch at Semnan Launch Site One in Iran," the president said. "I wish Iran best wishes and good luck in determining what happened at Site One."

A commercial satellite image shows just how much of Grand Bahama Island is underwater following days of torrential rain and massive storm surge from Hurricane Dorian.

Amateur satellite trackers say they believe an image tweeted by President Trump on Friday came from one of America's most advanced spy satellites.

The image almost certainly came from a satellite known as USA 224, according to Marco Langbroek, a satellite-tracker based in the Netherlands. The satellite was launched by the National Reconnaissance Office in 2011. Almost everything about it remains highly classified, but Langbroek says that based on its size and orbit, most observers believe USA 224 is one of America's multibillion-dollar KH-11 reconnaissance satellites.

Timothy Koeth's office is crammed with radioactive relics — old watches with glowing radium dials, pieces of melted glass from beneath the test of the world's first nuclear weapon.

But there is one artifact that stands apart from the rest: a dense, charcoal-black cube, 2 inches on a side. The cube is made of pure uranium metal. It was forged more than 70 years ago by the Nazis, and it tells the little-known story of Germany's nuclear efforts during World War II.

President Trump has tweeted what experts say is almost certainly an image from a classified satellite or drone, showing the aftermath of an accident at an Iranian space facility.

"The United States of America was not involved in the catastrophic accident during final launch preparations for the Safir [Space Launch Vehicle] Launch at Semnan Launch Site One in Iran," the president said in a tweet that accompanied the image on Friday. "I wish Iran best wishes and good luck in determining what happened at Site One."

Now we're going to bring you the story of a mysterious cube of uranium. The cube turned up one day in a suburb of Washington, D.C., after it had been lost for more than half a century.

NPR's Geoff Brumfiel has the story of the uranium and its dark past.

In the latest indication that it may be readying an attempt to launch another space rocket, Iran has given its launch pad a fresh coat of paint.

A satellite image taken by the commercial company Planet shows the pad painted a bright blue. The image, taken August 24, was shared with NPR. Until this month, the launch pad at the Imam Khomeini Space Center had been sporting a burn scar from a previous failed launch attempt. It had also been covered in debris from a possible flash flood at the site this past spring.

On Dec. 14, 1972, a capsule carrying Apollo 17 astronauts Eugene Cernan and Harrison Schmitt lifted off from the lunar surface.

It was the day that humans left the moon.

For a long while, they didn't come back, but that's changing. China, India and even smaller nations like Israel and South Korea are all pursuing robotic moon missions. Their lunar ambitions are being driven both by a desire to flex their technological muscles and by the rise of global nationalism.

China, India, smaller nations like Israel and Korea are all pursuing lunar ambitions. This month marks the 50th anniversary of the first moon landing, so NPR's Geoff Brumfiel decided to find out why so many countries have their sights on the moon.

Norwegian researchers have completed a survey of a sunken Soviet-era nuclear submarine that went down 30 years ago. The research team found that the sub is leaking a small amount of radiation from its reactors, but that it poses no threat to the surrounding environment.

Iran has crossed another line set in the 2015 nuclear deal between it and major world powers.

According to state media, Iran has begun enriching uranium above levels enshrined in the agreement. The move sends a signal that Iran is losing patience with a deal that has not provided the economic relief promised, more than a year after the United States withdrew from the agreement.

Victoria Girgis was leading a public outreach session at the Lowell Observatory in Flagstaff, Ariz., when one of her guests noticed a string of lights moving high overhead.

"Occasionally, you'll see satellites, and they look kind of like shooting stars moving through the sky," Girgis says. "But this was a whole line of them all moving together."

In January, a group of high-level military commanders gathered at an air base in Yemen. It was far from the frontlines of the country's ongoing civil war.

Then, without warning, a small drone appeared out of the sky and exploded, spraying the group with shrapnel. According to news reports, the blast killed several, including the Yemeni government's head of military intelligence.

North Korea's newest missile has a striking resemblance to an advanced Russian design, according to experts analyzing images from a test of the weapon on Saturday morning.

The missile, which North Korea describes as a "tactical guided weapon," appears superficially to be nearly identical to Russia's Iskander missile — a highly accurate short-range weapon capable of striking targets more than 150 miles away.

On the outskirts of Riyadh, Saudi Arabia is building what it sees as the future of its energy production.

A secretive group of scientists who advise the U.S. government on everything from spy satellites to nuclear weapons is scrambling to find a sponsor after the Defense Department abruptly ended its contract late last month.

The group, known as the Jasons, will run out of money at the end of April. The Pentagon says that the group's advice is no longer needed, but independent experts say it has never been more relevant and worry the department is throwing away a valuable resource.
