(Image credit: NASA/Bill Ingalls)NASA laid out ambitious plans for its return to the moon yesterday, as the space agency's administrator Jared Isaacman announced he was cancelling a planned space station in lunar orbit to use its parts for a $20 billion permanent base on the moon's surface, while also sending a nuclear-powered spacecraft to Mars.The announcement comes off the back of a major overhaul of NASA's Artemis program, which plans to return astronauts to the moon with the second mission in the program, Artemis II, launching as soon as April 1. The agency is now aiming for annual launches, potentially dropping SpaceX and Boeing from its mission plans, and targeting two lunar landings in 2028.The new lunar base plans, which will use a fleet of drones and robotic landers to establish a nuclear power station on the moon's surface by 2036, are ambitious to say the least, and motivated as much by a desire to stay ahead of China in the new space race as they are by any scientific purpose. Whether they're realistic, or simple lunacy, remains to be seen.The trend A helicopter drops water on the Cedar Creek fire outside Mazama in Washington state's Methow Valley.

And the problem could be compounded by staffing shortages at federal disaster response agencies.Three to readMars is hiding a secret clutch of gemstone-like crystals, including rubies and possibly sapphires [Live Science]Prominent researcher exits NASA, citing US attacks on science [Bloomberg]Iran war has already released a staggering amount of CO2 — and the destruction of schools, homes and buildings is the biggest source [Live Science]Graph of the day This year's daily sea surface temperatures are already setting records.

That's the globe's sea surface temperatures so far this year, which are continuing to break daily records set during the unprecedented year of 2024. And that's before the appearance of a possible "super El Niño" later this year, which could push global temperatures to unprecedented highs.Say it, said itWord of the dayTharsis — The Greek-Latin transliteration of the Hebrew word Tarshish, which is referred to in the Hebrew Bible as a wealthy land at the western extremity of the known world.
