Freaking. Awesome. Successful launch, successful first stage recovery.
Really wish I could have been home to see it.

Too bad they didn't show the landing live- they blacked out the actual landing on the drone ship. Given how new that is to space flight, that's one of my major highlights of modern launches.

C'mon Q!
Re: Space exploration: Where do we go from here?
After watching numerous launches in my 60 years, that still gave me goosebumps!
Awesome, amazing, riveting...

Me too. I also don't think I've ever been so nervous. I felt that disaster was completely possible. I've lost a lot of faith that we are in complete control when we launch.

Re: Space exploration: Where do we go from here?
Do you think that was intentional? I wondered if it was a snafu. They also had a hiccup right when the 2nd stage separated.
I have to admit the first time I saw them land in place on the sea platform I thought, "that... wait... is that possible?" I expected a very, very slow descent but f-cker stuck like a lawn dart.

Re: Space exploration: Where do we go from here?
Normally, I seem to recall that the landing is almost the same time as the landing firing event- and this time it very much wasn't. And they had the camera there exactly the same time as the burn time. So think they worried that they lost the stage in landing, and pulled the picture (to show later as a failure).
Odd that it was not second precise- especially since they hit a tiny little circle in the middle of the ocean on a floating barge.
Still, that is the coolest thing in modern launching. Especially the lawn dart look- see this streak coming down, a bright flash, and it's touchdown.

Re: Space exploration: Where do we go from here?
So the plan to dock is about 10:30am EST- but watching a live feed, they now think it may be early- as some of the events are coming early. While that seems good, as an engineer, I would wonder if this is unexpected- as any change in the system, early or late, is not actually nominal in terms of all calculations.
Anyway, the live feed is now the slow, slow, slow part of space travel. The dragon in close enough to the ISS that they are filming them live. But it's still about 2 hours away from docking. I'm sure this is very nerve wracking for the SpaceX group, though.

Stumbled upon this in my recommendations, it makes sense to explain it. I do recall seeing, maybe not entirely disrupted video, but atleast distorted video with previous landings.

I had no idea. I assumed they went in an instant. They lived for 165 seconds.

Somebody plugged different arbitrary values into the Drake equation and generated a different arbitrary result.

The plural of anecdote is not data
I find the Drake equation to basically just be a scam to get published at this point.

Examine some chicken entrails, we've got a new comet.
Draw an arc from Capella to Castor; tomorrow morning (around 4 a.m.) it will be dead center.

Perseverance rover liftoff successful. 2 million pounds of thrust. twss.
As they were completing the countdown JPL Mission Control was hit by a 4.2 magnitude earthquake so hey beat that Gene Krantz.

To pinpoint where the very slight air leak is coming from on ISS, NASA will have the crew stay in the Russian module (close to the Soyuz escape capsule), and seal up the other modules to see which one is losing air pressure.
This is the same leak that was discovered, and subsequently ignored because it's so small, last September. They're just now able to isolate the crew for the weekend.

I would absolutely love to hear GFMorris' take on this.
