Artemis I Launch to the Moon (Official NASA Broadcast) - NASA
Watch live as our mega Moon rocket launches an uncrewed Orion spacecraft on a six-week mission around the Moon and back to Earth. During #Artemis I, Orion will lift off aboard the Space Launch System (SLS) rocket, and travel 280,000 miles (450,000 km) from Earth and 40,000 miles (64,000 km) beyond the far side of the Moon, carrying science and technology payloads to expand our understanding of lunar science, technology developments, and deep space radiation.
Liftoff from Launch Pad 39B at NASA's Kennedy Space Center in Florida is currently targeted for 8:33 a.m. EDT (12:33 UTC) Monday, Aug. 29, at the start of a two-hour launch window.
Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars. We are going.

and they are in a "40 minute hold" to attempt to troubleshoot some issues with one of the fuel tanks. They had a weather delay (45 minutes) earlier, so probably won't launch at 8:30 am EDT. They have a 2-hour launch window this morning.
I caught this snapshot of it just before sunrise this morning -
to stabilize the temperature for launch. It was one of the bell engines under that large center tank -

Artemis I
Engineers are evaluating data gathered during the Artemis I launch attempt Monday, Aug. 29, when teams could not get the rocket’s engines to the proper temperature range required to start the engines at liftoff, and ran out of time in the two-hour launch window to continue. The mission management team will convene Tuesday afternoon to discuss the data and develop a plan forward.
The Space Launch System’s four RS-25 engines must be thermally conditioned before super cold propellant begins flowing through them for liftoff. Launch controllers condition them by increasing the pressure on the core stage liquid hydrogen tank to route, or “bleed” as it is often called, a portion of the approximately minus 423 F liquid hydrogen to the engines. Managers suspect the issue, seen on engine 3, is unlikely to be the result of a problem with the engine itself.
During the countdown, launch controllers worked through several additional issues, including storms in the area that delayed the start of propellant loading operations, a leak at the quick disconnect on the 8-inch line used to fill and drain core stage liquid hydrogen, and a hydrogen leak from a valve used to vent the propellant from the core stage intertank.

I grabbed what I thought was a great "red sky in morning, sailor's warning" pic.
I was taking all kinds of screenshots of the spacecraft! 
That combo of propulsion has to get the little guy at the very top, up to orbital speed (17,000+ mph) and then a bit faster to get it out of Earth's gravitational pull.
And when my grandmother's peace group visited the Exhibition for Economic Achievement in Moscow (sort of like a permanent world's fair), we chose to visit the space exhibition. The guide talked all about their early forays into space and how the cosmonauts had to be carried off after so long in space, their muscles atrophied and they couldn't walk. I had to go outside and get some air, made me feel kinda woozy (I didn't know I was severely anemic at the time). And the guide followed me out, she thought I was suspicious. I encountered that a lot there since I was the one who wasn't a senor citizen. 
that happened during school hours. They would roll the TV into the classroom.
They still roll astronauts off on a stretcher or a wheel chair due to the micro-gravity effects. That's why those on the ISS have an exercise bike and other exercise routines to reduce the muscle loss.
I bet that exhibition was pretty cool though. But then if they followed you, they may have been concerned enough that they didn't want you keeling over.
I did get chance about 25 years ago, to get to Houston and visit the Johnson Space Center. Didn't get to go into Mission Control that day because there was actually a shuttle in orbit so it was closed to visitors but did get to go around the museum and went to a movie in their IMAX theater.
And it was rare that they brought a TV into the classroom, but everybody watched the space launches! 
And I had the opportunity to see the first walk on the moon. I was a kid at summer camp - no TV at camp in the mountains of Vermont. But my friend and I just happened to be passing the camp nurse's cabin at the right time, she had a small TV and urged us to come in quick and watch! So we got to see that live, likely the only girls in camp who did 
I remember sitting on the steps from the 2nd floor to the living room watching (we had just moved to that house a year before).
What is wild though - just like the shuttle flights, the moon shots had become "routine" and people sortof stopped following them and of course, they eventually ended... But then when Sky Lab was launched, that reinvigorated the space program - at least briefly.
Then there were the probes to Mars and National Geographic would do big spreads on that and they did them for the moon landings too, complete with an enclosed map of the moon (we had a sub to that and I still subscribe to it - Disney now owns them 
).
In fact I remember all the "space stuff" - the Tang and the "freeze-dried ice cream" that they used to promote to gullible kids!!! I also remember they used to put plastic records on the back of cereal boxes. I think one brand (forgot which) had a moon-related one.
So we could watch those early launches...
But of course we talked about it in school. These got national attention, everybody watched. And back then, all you needed for the TV was just to plug it in.
But in the early '60s we lived in the North Country, on the side of a mountain - so all TV signals were blocked but one. So it was that channel - NBC affiliate - or nothing. Beautiful country, though, looked straight dow Lake George from the north end.
