“What the hell are you doing?” How I learned to interview astronauts, scientists, and billionaires

I recently wrote a story about the wild ride of the Starliner spacecraft to the International Space Station last summer. It was based largely on an interview with the commander of the mission, NASA astronaut Butch Wilmore. His account of Starliner’s thruster failures—and his desperate efforts to keep the vehicle flying on course—was riveting. In the aftermath of the story, many readers, people on social media, and real-life friends congratulated me on conducting a great Continue Reading“What the hell are you doing?” How I learned to interview astronauts, scientists, and billionaires

Rocket Report: “No man’s land” in rocket wars; Isaacman lukewarm on SLS

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We’re on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX’s blistering Starlink launch cadence. We Continue ReadingRocket Report: “No man’s land” in rocket wars; Isaacman lukewarm on SLS

Missing nitrogen: A dramatic game of cosmic hide-and-seek deep within our planet

Imagine if Earth’s history had a mystery novel, and one of its biggest unsolved puzzles was: Where did all the nitrogen go? Scientists have long known that our planet’s rocky outer layers—the mantle—are oddly poor in nitrogen compared to other volatile elements like carbon or water. Very strangely, the C/N and 36Ar/N ratios in the bulk silicate Earth (BSE, the whole Earth minus the metallic core) are far higher than those found in the meteorites that supposedly delivered these ingredients during the planet’s infancy.

Hubble captures a star’s swan song in planetary nebula Kohoutek 4-55

The swirling, paint-like clouds in the darkness of space in this stunning image seem surreal, like a portal to another world opening up before us. In fact, the subject of this NASA/ESA Hubble Space Telescope image is very real. We are seeing vast clouds of ionized atoms and molecules, thrown into space by a dying star. This is a planetary nebula named Kohoutek 4-55, a member of the Milky Way galaxy situated just 4,600 light-years away in the constellation Cygnus (the Swan).

Satellite galaxies gone awry: Andromeda’s asymmetrical companions challenge cosmology

The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal that this degree of asymmetry is only found in 0.3% of similar systems, painting Andromeda as a striking outlier in the current cosmological paradigm.

How NASA science data defends Earth from asteroids

The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA’s Center for Near Earth Object Studies (CNEOS) at the agency’s Jet Propulsion Laboratory in Southern California. The probability of collision peaked at over 3% on Feb. 18—the highest ever recorded for an object of its size. This sparked concerns about the damage the asteroid might do should it hit Earth.
