Wow, that mummified one looks like the prelude to a Stephen King story. :lol:

They got one thing wrong, though: It should say "Hostessing an organism of some sort." :thinking:

And that reminds me I meant to post about the Bennu asteroid mission. The sample grab was very successful-- in fact, so successful that they have the unexpected problem of the door being jammed open by space gravel, so they're losing volume. Hopefully they can get it closed before they have to make another attempt. They also have a cool video of Osiris Rex zooming in to bite Bennu. :lol:

^I've been seeing that. Now if it doesn't cause an Andromeda Strain we'll be OK.

Unless it combines with the Twinkie Mold.... :unsure:

The Twinkie Mold looks like it belongs on an asteroid. Actually, it looks like it is an asteroid. :lol:

A really small exo-planet might have been found.
With the likes of Oumuamua I wonder how often an exo-planet would pass through the solar system. Obviously no really large planets have barged through (I think we would have noticed) but a small one could slip in without harm.

If there are that many interstellar rogue planets, I wonder how many interstellar asteroids and comets there are. Traveling between stars may be even more hazardous than we expected.

Probably not considering how much space is in, er, space. :milky_way:

Yeah, but the more stuff there is, the worse it is. I was thinking about this yesterday. If you imagine a cylinder with the radius of your vehicle's forward profile and the length of your path from start to destination, what would the volume be? And then what would be the total mass of the matter within that volume? Would it add up to an asteroid or a planet or a star?

Unfortunately, I missed the actual launch by about ten minutes, but it looks like SpaceX is giving us another picture-perfect mission to the Space Station. :yes:

I intended to watch it live, but got distracted. It should be docking in about 45 minutes.

Actually, it was sometime early this morning. I think the schedule I looked at was combining Sunday and Monday. But they made it okay.

I checked in around 9:00 PST last night and it was in progress.

It looks like it's the end of the line for The Arecibo Radio Telescope. :bye:

Yeah, I was going to post about this. I saw it on one of my apps this afternoon. I can't believe it. :( It's such an amazing facility and has done so much incredible work for such a long time-- it's shocking that they would just demolish it like that. Somebody should do a Save Arecibo Kickstarter or something.

Something else to hate 2020 for. :mad:

I can understand part of their reasoning for it (not wanting nearby buildings damaged during a potential collapse), but on the other hand what value will those buildings have without the telescope?

I was thinking the same thing. It's too isolated to turn into a museum or anything, I think.

There is a push on to save Arecibo.

Nice! I signed the petition. But, man, did you see some of the other petitions on that site? Apparently literally anybody can start a petition.

Oh, and then there's this. Apparently the Galactic Emissaries are happy with the outcome of the election.
