China are catching up in space fast.

 

Hopefully soon they and the US, at least, will be able to come to an agreement where they can pool resources and cooperate in this field, rather than compete.

Suspect in this case competition = faster than collaboration.

Guess it depends if you want a future that's The Expanse at best and Mad Max at worst even if it's delivered expeditiously, I guess.

Scrapped last year apparently.

Not new or leading edge then :D

Oh wow! That was beyond belief, how the hell did it make it through reentry and successfully do the flip and land with that flap half burnt off?!?!

It was nothing short of breathtaking from start to finish. The launch, the multiple angles and the pictures from suborbit were stunning. 

 

The view of the plasma, then the flap beginning to disintegrate. Then to see the charred remains of it come back to life for the flip manoeuvre. Incredible. 

 

I think this is one of the most memorable spaceflights that I have seen live since the launch of STS-1.

The hosting was fantastic, hearing them laugh as it somehow kept going through reentry was great.


I'll be honest, I had major goosebumps listening to the emotion of them as it made it all the way to splash down.

I completely understand the emotion and exuberance - particularly in view of the blood sweat and tears that have been shed by all the Space X personnel to make this possible, but I'm not keen on the continual hollering, whooping and cheering. As an unmanned test I can see why they channel it into the live feed, but in particular, Artemis 3, during those tense moments as the HLS makes its first powered descent to the moon one would hope that they would exercise some decorum. When this arrives I will find it utterly terrifying.  

 

I wish I had been able to hear live Walter Cronkite's commentary in November 1967 during the launch of Apollo 4 and the first test flight of the Saturn V when the makeshift pre-fab studio began to disintegrate around him as the rocket ascended into the Florida sky. They did it so differently back then.

Shows the power of building so much redundancy into your control systems, I think.

 

Glad that fourth time round they pretty much nailed it.

Like you said, it's different these days. I wouldn't say it better or worse - just different.

 

I do think that when there are humans on board the vehicle and it's going for uncharted territory like Artemis III, the occasion will be naturally more reserved - at least until touchdown with everyone safe and stable is confirmed.

Absolutely - and crucial to the success of Apollo.

Took one of the most iconic photographs in history.

The Schienenzeppelin or Rail Zeppelin was an experimental railcar which resembled a Zeppelin airship in appearance. It was designed and developed by the German aircraft engineer Franz Kruckenberg in 1929. Propulsion was by means of a pusher propeller located at the rear: it accelerated the railcar to 230.2 km/h (143 mph) setting the land speed record for a petrol-powered rail vehicle. Only a single example was ever built, which due to safety concerns remained out of service and was finally dismantled in 1939.
Here you can find more info about it:

The journal BMJ Public Health is placing an expression of concern on a paper it said “gave rise to widespread misreporting and misunderstanding,” namely, “claims that it implies a direct causal link between COVID-19 vaccination and mortality.”

Deeply frustrating now the damage is done.

 

And that misinformation when manipulated by the media and presented to wide ranges of the public is most damaging.

In South Korea, the solar panels in the middle of the highway have a bicycle path underneath.
Cyclists are protected from the sun, isolated from traffic, and the country can produce clean energy.

What the Koreans have done with roughly an equivalent population to the UK in about a tenth of the available living space is remarkable, really. In a relatively short time, too.

Probably quite an accurate summation of the Fermi Paradox and the Great Silence. :D

Who'd be a science communicator, these days?
