Push to revive nuclear energy relies on deregulation; experts say strategy is misplaced. In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the…
“When you turn off those spacecraft’s radio receivers, there’s no way to turn them back on.” Federal funding is about to run out for 19 active space missions studying Earth’s climate, exploring the Solar System, and probing mysteries of the Universe. This year’s budget expires at the end of…
Meanwhile, Congress is trying to keep serious scientists from weighing in. While the Trump administration has continued to refer to efforts to avoid the worst impacts of climate change as a scam, it has done almost nothing to counter the copious scientific evidence that demonstrates that climate change is…
Engineered pathway lets carbon be plugged directly into key metabolic pathways. Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we’ve been pumping into the atmosphere. It would be nice to think that we could reforest…
North Korea test-fired a powerful new solid rocket motor for its next-generation ICBM. Welcome to Edition 8.10 of the Rocket Report! Dear readers, if everything goes according to plan, four astronauts are less than six months away from traveling around the far side of the Moon and breaking free…
Physicists spliced merger’s gravitational signal into isolated frequencies to determine surface areas. Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, the newly formed black…
“This is the first time we’ll have a space layer fully integrated into our warfighting operations.” The first 21 satellites in a constellation that could become a cornerstone for the Pentagon’s Golden Dome missile defense shield successfully launched from California Wednesday aboard a SpaceX Falcon 9 rocket. The Falcon…
Interpreting the data is tricky because other non-biological processes could account for the findings. Last year, we reported on the discovery of an intriguing arrow-shaped rock on Mars by NASA’s Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. Granted,…
SpaceX is targeting an orbital Starship flight with a next-gen vehicle next year. It has been two weeks since SpaceX’s last Starship test flight, and engineers have diagnosed issues with its heat shield, identified improvements, and developed a preliminary plan for the next time the ship heads into space.…
New research debunks some speculative climate fixes. A team of the world’s best ice and climate researchers studied a handful of recently publicized engineering concepts for protecting Earth’s polar ice caps and found that none of them are likely to work. Their peer-reviewed research, published Tuesday, shows some of…
