Next up - Falcon Heavy launch, then crew Dragon Starliner rescue mission return!!
Edit - my bad - crew Dragon return is normal Crew 8, the Starliner rescue is scheduled for early 2025, apparently. "If it's Boeing, we ain't going!" sigh

Oh my, that was like watching a movie. I could hardly believe my eyes when the rocket came back and landed in that launch tower.
Why did the other part of it explode after it landed? I think it was in the water.

Yeah, the Starship portion did a controlled "soft landing" on the water, at which point they had no control, it went down straight into the water, we saw a couple of frames underwater, vertical, before it bobbed back up to the surface - structural integrity gone, fuel tanks leaking, hot sparks still flying, things go <BOOM>, as expected.

Expected? Why didn't they land it somewhere like the other piece?
Thank you for that explanation. I was having a hard time making out what was going on in the video.

They're practicing soft landings on the water, no recovery, before they try landing on a barge or a landing pad. Same sequence as they went through first landing Falcon 9 boosters, actually.

Though yeah, they seemed spot-on with the accuracy, got very close to one of their pre-positioned camera buoys, so it seems accurate enough that I hope they actually try to land and recover the next one. It would take one heckuva large landing barge, though! :eek: That's like landing a 28-story building!!
 
These were taken from coastal South Carolina. The comet was readily evident to the naked eye...not what I'd call bright. The close-up was a Canon 6 with a 350mm Nikon manual lens, ISO 1600 about 25 seconds. I used one of those iOptron tracker thingies. I'll try it again these next few nights weather permitting.

Comets are always cool!

Tried to see the comet last night after sunset. Very clear out, but maybe washed out by the horizon sunset glow. Will try again for a few days. Unfortunately, the moon is getting brighter (fuller) and from what I've read, the comet will be dimming as it moves away from the sun.

Won't be back around for another 80,000 years, gosh darn it LOL. On it's last pass that long ago, current scientific beliefs (subject to change with more discoveries) indicate modern humans were just migrating out of our original homeland of Africa. Here's a paragraph from The Smithsonian.:

As the gaps are filled, the story is likely to change, but in broad outline, today's scientists believe that from their beginnings in Africa, the modern humans went first to Asia between 80,000 and 60,000 years ago. By 45,000 years ago, or possibly earlier, they had settled Indonesia, Papua New Guinea and Australia. The moderns entered Europe around 40,000 years ago, probably via two routes: from Turkey along the Danube corridor into eastern Europe, and along the Mediterranean coast. By 35,000 years ago, they were firmly established in most of the Old World. The Neanderthals, forced into mountain strongholds in Croatia, the Iberian Peninsula, the Crimea and elsewhere, would become extinct 25,000 years ago. Finally, around 15,000 years ago, humans crossed from Asia to North America and from there to South America.

Which brings us to today, where some modern humans are posting on TalkBass. :)

Very excited about the Europa Clipper satellite. Just don't know if I'll be around by 2030.
