Why not just put the tool on the robot that analyzes dirt on the spot so they don't have to fly it back 140M miles?

Don't the Mars rovers already have that?

Better call up NASA and tell them you have an amazing idea. I'm sure they will be so grateful.

Okay, I waited a few days before posting this. We have a 4th flyby coming through, announced a few days ago. About 500 to 1 odds according to that Loeb psyop guy.

"Perihelion... 0.9 AU-just inside Venus's orbit"

Considering Venus is orbiting at 0.72 AU, this shows how serous the article is.

(also, the numbering doesn't quite make sense - the Zwiki catalog is typically date-three letter)

Can't find anything else on this, also the perihelion is on the same date as the other object that's been in the news over the last few months. Looks like AI-generated clickbait BS.

A cool writeup on a plan to send laser-powered probes to Alpha Centauri using realistic technology
Now, though, a cadre of researchers are working to make interstellar travel a reality, at least to our nearest neighbors. They are coalescing around an approach that could lead to closeup images of a star and an exoplanet just 25 years after mission launch.
More details on the tech

Next Starship test on Oct 13. The one after that will be the first of the redesigned V3 version.
