The Trump-Musk Fight Could Have Huge Consequences for U.S. Space Programs

3 weeks ago | scientificamerican.com | Lee Billings

For several hours yesterday, an explosively escalating social media confrontation between arguably the world’s richest man, Elon Musk, and the world’s most powerful, President Donald Trump, shook U.S. spaceflight to its core. The pair had been bosom-buddy allies ever since Musk’s fateful endorsement of Trump last July—an event that helped propel Trump to an electoral victory and his second presidential term.
Why Trump’s ‘Golden Dome’ Won’t Shield the U.S. from Nuclear Strikes

During a briefing from the Oval Office this week, President Donald Trump revealed his administration’s plan for “Golden Dome”—an ambitious high-tech system meant to shield the U.S. from ballistic, cruise and hypersonic missile attacks launched by foreign adversaries. Flanked by senior officials, including Secretary of Defense Pete Hegseth and the project’s newly selected leader, Gen.
What to Know about Kosmos-482, the Soviet Spacecraft Crash-Landing on Earth

A defunct spacecraft from the former Soviet Union that has been stuck in space for more than half a century is, at last, about to come home. Kosmos-482 was launched on a voyage to Venus in March 1972 as part of the Soviet multimission Venera program. Thanks to a rocket malfunction, however, it never escaped Earth orbit.
Trump Seeks to Cancel NASA’s Mars Sample Return—And Scientists Are Outraged

For more than four years, NASA’s Perseverance Mars rover has been on the prowl within Jezero Crater, a site on the Red Planet that eons ago harbored a sprawling river delta, a large, deep lake and—just maybe—ancient Martian life. Since its touchdown in February 2021, the car-sized, nuclear-powered robot has traveled far and wide across this otherworldly terrain, dutifully gathering samples of rock and soil.
Quantum Randomness Could Create a Spoof-Proof Internet

The allure of quantum computers is, at its heart, quite simple: by leveraging counterintuitive quantum effects, they could perform computational feats utterly impossible for any classical computer. But reality is more complex: to date, most claims of quantum “advantage”—an achievement by a quantum computer that a regular machine can’t match—have struggled to show they truly exceed classical capabilities.
Breakthrough Prize Winner Gerard ’t Hooft Says Quantum Mechanics Is ‘Nonsense’

SpaceX’s Private Fram2 Mission Reaches Polar Orbit—But That’s Not the Most Impressive Part

2 months ago | scientificamerican.com | Lee Billings

In some respects, the most notable thing about Fram2, the private four-person space mission that launched on Monday night on a SpaceX Falcon 9 rocket, is its polar orbit. Named after the Norwegian polar-exploration vessel Fram, the Fram2 mission marks the first time humans have occupied this particular slot around our planet, a swooping ellipse that takes a SpaceX Crew Dragon spacecraft between Earth’s North and South Poles in about 45 minutes.

Are D-Wave’s Claims of ‘Quantum Advantage’ Just ‘Quantum Hype’?

Mar 13, 2025 | scientificamerican.com | Lee Billings

D-Wave, a British Columbia–based technology firm, made a scientific and stock-market splash on Wednesday with its declaration of a breakthrough in quantum computing. But for some experts, the company’s claims are landing with a thud. What Did D-Wave Do?
