New details of the Trump administration's plans for NASA, released Friday, revealed the White House's desire to end the development of an experimental nuclear thermal rocket engine that could have shown a new way of exploring the Solar System. Trump's NASA budget request is rife with spending cuts. Overall, the White House proposes reducing NASA's budget by about 24 percent, from $24.8 billion this year to $18.8 billion in fiscal year 2026. In previous stories, Ars has covered many of the progr

tldr: There's a lot of bullshit going on right now about Lithium propulsion boats and planes, don't trust the energy return on investment or viability of its profitability...it's fundamentally a net negative energy return on investment. Elon lies through his teeth and boldly in a room full of people. Physicists Get Too Much Street Cred and Access to Venture Capital I think the physicist mindset has infected a large swath of venture capital with delusions about what's possible with lithi

Forward-looking: British startup Pulsar Fusion has unveiled its ambitious nuclear fusion rocket concept, Sunbird, designed to dramatically shorten interplanetary travel times. Developed in secret over the past decade, the project aims to cut the journey to Mars in half and reach Pluto in just four years. With ground testing scheduled for 2025 and an orbital demonstration planned for 2027, Sunbird could mark a bold leap forward in next-generation propulsion technology. Unlike conventional chemic

A British startup called Magdrive claims to have developed a satellite that uses solid metal as a source of fuel. Its founder says it could even one day be used to clean up space junk — by gobbling up dead satellites and using them for propulsion. As CNN reports, the company came up with a propulsion system, dubbed Warlock, that ionizes solid metal, instead of current electric systems that generate power by ionizing pressurized gas. The goal is to balance efficiency with power output. "Chemic

Orbital mobility took center-stage in the space industry last year, with venture capitalists funneling massive sums into startups developing tech for nimble satellite operations. So it’s no surprise that one of the most recent deals is to Magdrive, a UK-based startup that says its electric propulsion system for satellites will deliver a higher thrust in a smaller form factor than anything else on the market. Spacecraft designers have to consider a number of trade-offs when purchasing or designi
