Three uncrewed missions targeted for later this year will involve private companies carrying payloads to the lunar surface ahead of astronauts' return by 2028. Nonetheless, some experts have voiced skepticism about NASA's highly ambitious timeline, with the gigantic detonation of Blue Origin's New Glenn rocket during a static "hotfire" test likely prompting significant delays.
In other space news, the solar system's largest moon, Jupiter's Ganymede, may be heating up due to a unique and mysterious process linked to the planet's inexplicable magnetic field, an unexpected effect is squeezing Mars' atmosphere like toothpaste, and bizarre, scratch-like patterns on Venus' surface have scientists scratching their heads.

Today's artificial intelligence (AI) chatbots are notoriously prone to getting things wrong.
To get more accurate, large language models historically (LLM) had to get bigger, using ever more parameters and thus gobbling up more compute time. Now, however, scientists have found a way around this seemingly inevitable tradeoff — and they did it by inserting a quantum computing component into the AI.
The result led to a small reduction in the perplexity score — used to quantify the inaccuracies LLMs make in predicting their next tokens — and an improvement in the questions the hybrid AI could answer compared with a base model.

Antarctica's Thwaites Glacier is nicknamed the "Doomsday Glacier" because its collapse would raise global sea levels by 2.1 feet (65 centimeters) and flood coastal communities worldwide.
This week, we reported that a key shelf buttressing the glacier is set to fall apart this year.
It sounds depressing, but that doesn't necessarily spell immediate doom. While scientists can't put an exact timeline on Thwaites Glacier's collapse, they don't think it will be anytime soon. That at least gives people living in cities such as New York, Boston, and Miami a little time to consider moving inland.

The U.S.-Israeli war has come at a price measured not just in military expenditures but in human lives, key infrastructure and rising energy prices.
But some costs of the war aren't immediately apparent. One of the less-publicized tolls, for example, is the effect on Iran's water system, which was already collapsing before the current war. In this Science Spotlight, Live Science staff writer Sascha Pare walks us through how the water crisis originated, how the war made things worse, and whether the situation can be turned around.

This snapshot of the bruised-blue Martian surface was taken by NASA's Psyche spacecraft as it passed within 2,864 miles (4,609 kilometers) of the Martian surface on May 15.
The image — a close-up of the double-ringed Huygens crater and the cratered southern highlands that surround it — was captured by the probe to test its multispectral cameras before it arrives at the metal-rich asteroid 16 Psyche in 2029. The enhanced-color processing in the photos revealed veins of hidden mineral deposits, hence the blue.
