NASA Pulls the Plug on Jupiter-Moon Lander, So Scientists Propose Landing It on Saturn (gizmodo.com) 29
"NASA engineers have spent the past decade developing a rugged, partially autonomous lander designed to explore Europa, one of Jupiter's most intriguing moons," reports Gizmodo.
But though NASA "got cold feet over the project," the engineers behind the project are now suggesting the probe could instead explore Enceladus, the sixth-largest moon of Saturn: Europa has long been a prime target in the search for extraterrestrial biology because scientists suspect it harbors a subsurface ocean beneath its icy crust, potentially teeming with microbial life. But the robot — packed with radiation shielding, cutting-edge software, and ice-drilling appendages — won't be going anywhere anytime soon.
In a recent paper in Science Robotics, engineers at NASA's Jet Propulsion Laboratory (JPL) outlined the design and testing of what was once the Europa Lander prototype, a four-legged robotic explorer built to survive the brutal surface conditions of the Jovian moon. The robot was designed to walk — as opposed to roll — analyze terrain, collect samples, and drill into Europa's icy crust — all with minimal guidance from Earth, due to the major communication lag between our planet and the moon 568 million miles (914 million kilometers) away. Designed to operate autonomously for hours at a time, the bot came equipped with stereoscopic cameras, a robotic arm, LED lights, and a suite of specialized materials tough enough to endure harsh radiation and bone-chilling cold....
According to the team, the challenges of getting to Europa — its radiation exposure, immense distance, and short observation windows — proved too daunting for NASA's higher-ups. And that's before you take into consideration the devastating budget cuts planned by the Trump administration, which would see the agency's funding fall from $7.3 billion to $3.9 billion. The lander, once the centerpiece of a bold astrobiology initiative, is now essentially mothballed.
But the engineers aren't giving up. They're now lobbying for the robot to get a second shot — on Enceladus, Saturn's ice-covered moon, which also boasts a subsurface ocean and has proven more favorable for robotic exploration. Enceladus is still frigid, but `has lower radiation and better access windows than Europa.

You are all wrong! Young people working on the project weren't aware of the warning about landing on Europa we had received. When made aware, they simply took it into consideration and decided it would be safer to land on a Saturn Moon instead. Plain and simple!

Yes, NASA decided that it was too difficult a mission for the time being. Budget cuts were just another convenient excuse.
When you think about the fact that NASA can't even get it's shit together enough to get the "close to home" Artemis moon mission, that was supposed have landed in 2024, going it really shouldn't be a surprise that they mothballed Europa.
Frankly I don't think that an Enceladus mission has a snowball's chance in hell either. It will cost just as much as Europa, be almost just as difficult, and has only slightly fewer hurdles like radiation and communication windows.
NASA has been a mess for years. An absolute shadow of its former self and SPaceX laid all their excuses bare.Trump budget cuts don't help NASA at all, but they do give NASA an excuse.

You know what, after the DOGE fiasco, no more just getting to say an agency "is a mess" using something such really as benign as a delayed mission to land on the moon. You need to justify that statement and then disconnect it from things out of their control like in fact funding and directives which come both from Congress (cough, cough, Richard Shelby [arstechnica.com]) as well as the Executive who happens to change every so often.

Manned missions have always been a budgeting headache because they take a lot of money, a lot of time, and a consistent Congress, the last one rarer than the Holy Grail. US unmanned probes are more often on budget and have been quite successful overall.

So, that's the impression the headline and summary gives, but if you RTFA, it does state that the current meshugas is not responsible for this. But it's not at all clear from the article that the cancellation predates this by quite a bit; several years. Studies of it began in tandem with development of Europa Clipper, but ultimately there wasn't enough funding for both, and that we weren't ready for it at this point.
It's not like there's hardware already built and ready to send up, either. Yes, there were studies, but the lander never even got to Phase A (Concept and Technology Development), which would have required a new start from Congress.
It's also not at all clear to me that you'd even want to send the same hardware to Enceladus that you'd designed for Europa. They both would land on ocean worlds, but apart from that, this would appear to be an entirely new mission concept.

A lander for Europa will need a lot of radiation protection. Enceladus would be easier because you don't need the highly radiation tolerant electronics and all the associated testing.
Other than that, the spacecraft would be mostly the same. Enceladus would be easier to land on, with a lot less delta V needed; but the trip there will take longer.

The Europa Clipper will have taken high resolution images of Europa before the lander arrives, which would help choose a suitable landing spot. It also takes a lot longer to get to Saturn / Enceladus which would extend the mission timeline and costs. Enceladus is a lot smaller so less delta-V and a smaller spacecraft, and maybe that is really what is pushing for this change?
