NASA's Nuclear Option

NASA May Prepare Nuclear Strike Against Asteroid Threatening To Crash Into the Moon

Scientists are evaluating whether a nuclear strike could be the last line of defense against an asteroid that might collide with the moon in 2032.

The object, known as 2024 YR4, was discovered in December 2024 and quickly gained attention for its potential impact risk.

Initial observations suggested the asteroid, measuring about 180 feet (55 meters) across, had a relatively high chance of hitting Earth in 2032, peaking at 3.1%. That figure was large enough to draw headlines, since an asteroid of that size could level a city if it struck our planet.

Follow-up measurements, however, sharply reduced the risk. By February 2025, the odds of the asteroid impacting Earth fell to just 0.28%, or less than 1 in 360. Instead, the main concern now is a possible collision with the moon. If 2024 YR4 crashes into the lunar surface, it would create a massive spray of regolith — the dust and small rocks covering the moon.

Scientists are recommending fragmenting the asteroid before impact. One option currently on the table? Detonating a rocket-delivered nuke on or near the asteroid that could shatter the rock before it collides with the moon.

Sam Altman’s AI Empire Will Devour As Much Power As New York City and San Diego Combined. Experts Say It’s ‘Scary’

Picture New York City on a sweltering summer night: every air conditioner straining, subway cars humming underground, towers blazing with light. Now add San Diego at the peak of a record-breaking heat wave, when demand shot past 5,000 megawatts and the grid nearly buckled.

That’s almost the scale of electricity that Sam Altman and his partners say will be devoured by their next wave of AI data centers — a single corporate project consuming more power, every single day, than two American cities pushed to their breaking point.

The announcement is a “seminal moment” that Andrew Chien, a professor of computer science at the University of Chicago, says he has been waiting a long time to see coming to fruition.

“I’ve been a computer scientist for 40 years, and for most of that time computing was the tiniest piece of our economy’s power use,” Chien told Fortune. “Now, it’s becoming a large share of what the whole economy consumes… now [computing] could be 10% or 12% of the world’s power by 2030."

The question is, what energy source, if any, can keep pace with AI's insatiable demand?

Trump Expected To Sign a TikTok Deal Thursday

President Donald Trump is expected to sign a deal today to facilitate the sale of TikTok from a Chinese-based company to a group of American investors, two senior White House officials said yesterday.

A senior White House official confirmed on Wednesday that once the deal was implemented, TikTok's U.S. operations would be run by a new joint-venture company. ByteDance, TikTok's current China-based owner, will hold less than 20% of the stock of the new company.

The structure would comply with a bipartisan law passed in 2024 that sought to ban TikTok if it wasn't sold to U.S.-based owners this year.

Trump told Fox News in an interview Sunday that Oracle's co-founder Larry Ellison would play a role in the deal. He also said Michael Dell, CEO of Dell Technologies, and the Murdoch family, which owns a media empire that includes News Corp. and Fox Corp., would play a role.

Trump added that the other business leaders involved in the deal are "really great people, very prominent people."
