I don't think we've ever had such sharp live TV from the moon. The TV cameras carried by Apollo, although technically advanced for the time, were crude and very low reslution. Those pictures we've just seen were so clear - it was almost "2001" stuff.

Actually, "earthset" on this occasion. We'll get an "earthrise" image as the Orion spacecraft emerges from behind the moon.

We've had quite a few images like this, dating back to 1966 but not live and in such detail.

For a lot of the Apollo missions, that's all we ever saw.

I've been waiting for this for over a decade. I always knew that once we got modern HD TV imagery from the moon it would be stunning. The next step will be to get such live TV imagery direct from the surface.

That really looks like something from a science fiction show - very good quality images.
Let the conspiracy theories start frown
Don't even mention such nonsense - it only encourages them.

Nothing at the moment as NASA has ceased their broadcast. Other You Tube "live" images at the moment are real time animations based on live telemetry.

The live TV images are coming from a number of Go Pro cameras mounted on the extended solar panels. That allows us to see part of the body of the service module.

I think, during the Shuttle era, the pads were damaged on a regular basis. On one occasion, part of the concrete slab lining of the flame trench were ripped off and thrown around.

People have died in and around launch pads so timely reminders are never out of place. People forget that the Space Shuttle killed more than the 14 crew who died on Challenger and Columbia.

And a number of people were killed in an explosion in the factory that made the fuel for the solid rocket boosters.

It was in response to my comment that a number of people in general had died during the Space Shuttle programme over and above those killed in the actual Shuttle accidents.

Working with rockets (whether on a launch pad or anywhere else) is an inherently dangerous activity due to the noxious substances, dangerous gases and risk of explosions and fires.

During the countdown to the launch of Artemis 1 the Red Team were sent out to the pad, when the rocket was pretty much fuelly fueled, to tighten up some nuts to try and stop those pesky hydrogen leaks. That was a pretty risky thing to do because, apart from the general rule that you keep people away from fully fueled rockets, the base of a fully rocket is an extremely dangerous environment. It was in that area where we had the fatalities just before the launch of STS-1 in 1981 mentioned above. The casualties were asphyxiated by nitrogen gas.

Are you suggesting that they don't need "Danger" signs to warn people when there is danger present?

It's not a new thing. Lots of danger indicators have been festooned on aircraft, launch towers and dozens of other apparatuses since the year dot.

Think of the danger triangles you see on ejector seat equipped aircraft. They've been around forever.

There will be ample signage where it’s needed.

It looks like they lost communication with the Orion for about 45 minutes. Contact has now been restored but they are still looking into what caused the glitch. My hunch is that it was a piece of faulty ground equipment.

Don't expect the mainstream media to pay any attention to it unless it goes seriously wrong. You need to make an effort to follow these types of missions these days. The good news is that there are plenty of resources available out there where you can keep up to date as to what is happening.

There are many, many reasons why Artemis will not give us a manned lunar landing before 2030.

Forgive my ignorance, but how does it cost $1 Billion (trying hard not to use Dr Evil voice) to build a launch tower? I presume that it includes the base structure, ancillaries etc, but a billion?
Because specs keep changing resulting in delays, redesigns etc. The funding has always been the problem - being intermittent and uncertain.

Watching now. NASA just took down their telemetry based animation screen for some reason.

So, it's splashed down safely, which is great. It's orbited the moon and come back safely to Earth.

Which is what Apollo 8 did in 1968, 54 years ago. Excuse my ignorance but what extra meaningful scientific hurdles has Orion cleared, other than (one day) having an extra astronaut?
It was not specifically a scientific mission. It was an engineering test flight to ensure the basic elements of the system worked - which it appears to have achieved. Some small scientific tests were tacked on as a "bonus" so as not to waste the opportunity but they are not the purpose of the mission.

If you are going to talk about earlier around the moon and return to earth missions, Apollo 8 wasn't the first either.
