Not to mention that the current budget (and proposed budget from the Senate) fund this mission, so why do they think a Democratic Congress would be able to make this go away?

RFK Jr. backs down all the time when he gets push back, so if anyone wants to call, here's the HHS number 1-877-696-6775.
I'd also call your senators/reps as well.

I think it's because he puts out clickbaity press releases/headlines, and since he's at Harvard, reporters can publish them without being questioned.

A rotation movie of Jupiter created using a global map of Jupiter I recently finished. The map is created from 135 Voyager 2 images from June 28, 1979. Two rotations are shown. In rotation 1, approx true color/contrast are used. Rotation 2 has exaggerated colors/contrast.

The moon on October 24, 1970, from Zond 8. The spacecraft was looping around the moon and would return to earth. This image was taken on film, which was developed after it landed on earth.

LOL, Juno doesn't even have reliable thrusters for getting in its planned orbit.

For the record, I am confident that if we imagined that your car had enough onboard delta-v capability, we could calculate a trajectory for it to intercept 3I/ATLAS.

That does not mean that it's worth writing a non-peer-reviewed paper about it, though, let alone hyping that paper.

To be clear, a lot of people do a lot of incredible things there. But the idea that just because it comes from Harvard it is legitimate is wrong. And reporters who think that way and amplify garbage like this need to be treated with derision.

As long as Harvard continues to employ people like Avi Loeb, the idea that being associated with it conveys some sort of authority is just a silly thing gullible people believe.

While three plumes were spotted, the quality was not deemed good enough to justify using that much limited tape recorder storage and bandwidth, and it was never tried again.

One of the Galileo orbiter's jobs at Jupiter was to take full color plume inventory movies of the volcanic moon Io throughout the mission. Its stuck antenna prevented this. On its second orbit, the team tried to send pack such a movie but using highly compressed violet filter images.

Proteus, moon of Neptune, from Voyager 2 in 1989. The original image is at a pixel scale of 1.3 km/pixel, but it is badly underexposed. At 420 km across, Proteus is one of the largest irregular objects in the solar system, at least among objects for which we know the shape.

The same view without correcting Io

When processing images like this from most planetary spacecraft, which take images through multiple filters to be combined into a color image, each world has to be done separately, as they move relative to one another between frames.

Quick aside, I'm really happy that more big TNOs/dwarf planet candidates got official names this year, 2 decades after their discovery :D
