Rockets are becoming cheaper and more powerful than before thanks to new technologies. As companies make space more accessible and NASA returns to crewed spaceflight, a new era of space exploration seems to be on the horizon. But will this seeming rocket Renaissance become just more than hype? NOVA explores the latest rocket technologies and the growing role private citizens may have in space.

After 15 years of searching finally I've discovered it: a youtube video those title literally describes it's content - rockets rising to sky. Thank you.
-
Thanks PBS. Its timely to remind us that Humans can do wondrous things that inspire great achievements. If we can turn away from division, war and tribalism then the Future is anything we can imagine.

Ya, a little on the late side, but still thoroughly enjoyed it! It answered several lingering questions I had about some of the rocket designs. Thanks for posting and keep them coming 👍 🤘😁🖖

Incredible that people whine about the fact that this is a bit dated. They certainly want a lot .... for absolutely nothing. This is amazing information.

The testing was something else. As a kid, I went to school about a mile away from where Rolls Royce tested their jet engines (underground), the last test was about 10am, we had to stop class, not only couldn't we hear, the ground and windows shook. Under Hucknall Aerodrome an ex WW2 airfield, with the concrete bunkers still there at perimeter.

Fascinting to watch this knowing what we know now

Embracing the revolution 🚀

Thanks PBS America you rock, i like all your videos

It would be nice if the original airdate was included in the description. Right from the first couple of minutes it’s clear this is out of date (ie less than 600 people in space). Still good content but it would be useful to have some context. Edit: okay at the point of SLS renderings (when SLS has launched) I had to look this up myself. This is episode 5 of season 46 airing on 13/02/2019 (or 02/13/2019 for Americans). Currently 4 years out of date. A LOT has happened since then, including first manned flights for Virgin Galactic and Blue Origin, the selection of a moon lander, and built prototypes and testing of Starship (just had the booster 30 engine static fire, with orbital launch imminent), Dear Moon crew selection, Polaris mission announcement, and the first full tourist orbital flight with no professional astronauts onboard on Crew Dragon. Oh..and crew rating of Dragon😅 with multiple missions to the space station. And lest we forget, China fully building their own space station.

New subscriber in this channel & loooving every videos , already have seen 3 excluding this one!!

that waterrocket guy cracked me up
-
Artemis obviously, up to where i was watching the mission name was not mentioned..though it's thrust was increased from optimal for launch testing purposes.
-
Haha the edit was funny and put a smile on my face before the intended smile on my face!

Wonderful, thank you !!:cat-orange-whistling:

And virgin has been relying upon space x for a while too🚀

That water rocket is really fun. I've seen people cutting two PE bottles, applying a very strong glue to make an almost 3 liter bottle, and glue a valve into the "top" that opens at once. That double bottle can be pumped up to 9 bar, filled with half water, half air, that works best. Nine bar is pretty dangerous. So, you absolutely must do the glueing exactly like the experts showed you: sand the joint using the RIGHT type of sandpaper, use the type of glue the experts showed you, apply the right amount of glue (not too much, not too little), have the glue curing at the right temperature and time. And the fins that keep your rocket stable, better go for an existing design, later you can experiment, when you know these things better. You do not want a high pressure air rocket exploding into you face, or coming for you. And ah, when you add a small return parachute, there are very clever release mechanisms, and mechanisms that fail half the time. The choice is all yours. By the way, search water rockets, the large ones fly hundreds of meters into the sky. Those are no toys anymore. Still, if you know what you are doing, you can build them yourself.

Can we all spare a thought for the pigeon at 24:39...

United Star Ship Enterprise was built by a United Earth where no countries waged war with other countries. Getting countries to stop attacking or firing rockets as saber rattling is the first step. We got our work cut out for our grandchildren.

What type of paint are they using on a rocket that travels over Mach 20?
