TL;DR: NASA's public Planetary Data System is at risk of being shut down. Anyone have any ideas for backing it up?

Hi everyone,

Bit of a long-shot here, but I wanted to try on high-quality tildes before jumping back into the cesspool of reddit. I'm posting it in ~science rather than ~space as I figure interest in backing up public data is broader than just the space community.

I work regularly with NASA's Planetary Data System, or PDS. It's a massive (~3.5petabytes!!) archive of off-world scientific data (largely but not all imaging data). PDS is integral for scientific research - public and private - around the world, and is maintained, for free, by NASA (with support of a number of Academic institutions).

The current state of affairs for NASA is grim:

• NASA Lays Off ISS Workers at Marshall Space Flight Center
• More layoffs at JPL
• NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say

And as a result, I (and many of my industry friends) have become increasingly concerned that PDS will be taken down as NASA is increasingly torn down for spare parts and irreparably damaged. This administration seems bent on destroying all forms of recording-keeping and public science, so who knows how long PDS will be kept up. Once it's down, it'll be a nightmare to try and collect it all again from various sources. I suspect we'll permanently lose decades worth of data - PDS includes information going all the way back to the Apollo missions!

As such, we've been pushing to back-up as much of PDS as we can, but have absolutely no hope of downloading it all within the next year or two, nevermind in a few months if the current cuts impact us soon.

If you or someone you know would be interested in helping figure out how we can back-up PDS before it's too late, please let me know here or in a DM. I've already tried reaching out to the Internet Archive, but did not hear anything back from them.

Edit: to clarify, the larger problem is download speeds - we've topped out at 20mb/s with 8 connections.

I was reading this Reddit post and was curious about whether the passengers of this theoretical spaceship could experience 1g of acceleration forever assuming the ship has an infinite fuel source.

They shouldn’t be able to pass the speed of light relative to an outside observer, but is there some phenomenon where the passengers can feel like they are accelerating forever?

As of July 1st, all articles are behind a paywall. This includes all historical articles (going back decades, apparently), including any and all InternetArchive copies -- so RIP every Wikipedia link that has ever referenced them as a source. A free-registration option gets you access to 3 articles per month. A proper subscription is $230/year.

A freelance journalist who has been published with them in the past had this to say about it, which I thought was enlightening and, well, thoughtful.

On SpaceNews going paywalled, and the broader disregard for archiving in journalism.

I reviewed his stuff a bit, and I like his writing, so I added his RSS link to my feed (while simultaneously deleting my SpaceNews link), and on a whim--because he has his email right there on his "About" page, I emailed him to tell him that I liked his article and I just replaced SpaceNews with him.

Like, an hour later, I received a response from him, reminding me that he focuses primarily on the Moon, and that he loves RSS and is happy to hear people still use it.

And it was so refreshing to connect--almost directly--with an actual human being writing news.

Just thought I'd share.

Oh, I also want to comment on that price ... $230/year is--IMHO--wildly overpriced. But almost immediately, it also occurred to me that they probably lost more readership going from $0/year to $1/year, than going from $1 to $230 so, you know, business-wise, I suppose it's not exactly a horrible decision.

But I'd like to hear other people's opinions on that price, too.

I'm building a fun bit of code that uses public APIs to track the location of unusual orbital objects. Including the Tesla Roadster still drifting somewhere between us and Mars, the "Trash Bag object" orbiting Earth, Oumuamua, and some famous satellites like the Voyager probes.

What would you include in a highlight reel of random stuff moving around in our solar system? I leave the scope as broad as possible: an observable object in our solar system of any size or mass.
