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.

Earlier this year, President Trump laid out an ambitious plan for U.S. missile defenses. "Our goal is simple," Trump said during a speech in January. "To ensure that we can detect and destroy any missile launched against the United States, anywhere, anytime, anyplace."

To reach that goal, the administration's proposed new defense budget calls for hundreds of millions of dollars to study the use of lasers and particle beams in space. "It's new technology," the president said.

Except it isn't.

Early Friday morning, Japan's Hayabusa2 spacecraft detonated an explosive device over a small asteroid. The goal was to create a fresh crater that will later be studied by the spacecraft.

India says it shot down one of its own satellites, making it only the fourth country to test an anti-satellite weapon.

India's Prime Minister Narendra Modi announced the successful test on Wednesday in a rare national address and on social media. The test would "have a historic impact on generations to come," Modi said in a tweet.

The announcement comes just weeks before national elections in which Modi's party has tried to paint itself as being hawkish on national security.

A Spanish court says assailants who broke into North Korea's Embassy in Madrid last month later fled to the U.S.

According to new documents unsealed on Tuesday, the perpetrators of the attack included a U.S. citizen and another resident. The leader of the plot fled via Lisbon to Newark, N.J., and offered stolen material to the FBI in New York.

The Missile Defense Agency says it has conducted another successful test of its ground-based interceptor system.

Monday's test involved a missile carrying a dummy warhead fired from Kwajalein Atoll in the Pacific Ocean toward the U.S. West Coast. Sensors tracked the missile as it flew, and then two interceptors were launched from Vandenberg Air Force Base in California.

Satellite imagery of a space launch center in northern Iran suggests a second attempt to launch a satellite has failed.

The imagery, taken Wednesday by San Francisco-based company Planet and shared with NPR, shows burn scars on a newly painted launchpad at the Imam Khomeini Space Center. The burns appeared after days of activity at the site, which suggested Iran had been preparing for a launch.

At a Russian base on the Baltic Sea, construction is underway to house a new generation of nuclear-capable missiles.

Tentlike structures have popped up to shelter the mobile missile system, known as Iskander, which is capable of firing weapons with both conventional and nuclear warheads. Recent satellite imagery of the territory, known as Kaliningrad, also shows that old buildings on the base are being demolished.
