No, because it isn't the Apollo spacecraft. Orion is solar powered and hence basically needs to pointed at the sun (nose or tail first). BBQ roll was unique to Apollo. Most, if not all, spacecraft don't do it.

A minor point of annoyance has been the continuous pointing out of records set by a "spacecraft designed for humans" in press releases. A crewed spacecraft's mission is very different from one without that crew.
Apollo 13, as well as the other eight lunar flights, had three men onboard and Orion has zero. Not sure it is appropriate to compare these. Difficult to see Orion as anything other than another unmanned mission and assigning "records" seems disingenuous.
SpaceX launched a dummy to the orbit of Mars. Granted that the Tesla onboard was not designed to support life, but until a crew makes the trip, it is challenging to accept the setting of new records based upon the “designed for humans” distinction. This is not to take away anything from an important test mission of a new spacecraft. Just not sure that records are being set.

The Apollo 13 crew still holds the Guinness World Record for the "farthest distance from Earth reached by humans."
The Apollo 13 spacecraft also set a distance record and that is the one that the Artemis I Orion surpassed. Whether or not it is a valid record, using it as a news hook was an effective way of engaging the public in the mission, if only based on the reach and readership for our own article about the distance being surpassed.

I agree that a trajectory plot (in the form of what was done for the Apollo missions) would certainly be more useful than many of the diagrams that we have seen up to this point. In that vein, I created this diagram from a screenshot taken from NASA's AROW website.
The positions of the moon are approximations. Also, the entire plot might need to be rotated somewhat, as I am not certain what convention was used for the Apollo trajectory plots. I oriented this diagram merely to fit into a nice rectangle. None-the-less, I found that this diagram helped me understand the Artemis I flight a bit better.

As Robert indicates, "news hooks" are very important to keep the interest of the general public. In its own way, Apollo 13 became a "news hook."

Agree. At the risk of sounding like an old fuss-bucket, I also don't care for today's fluffy and bubbly PAO and launch commentary that we're getting from both SpaceX and NASA one bit. It almost sounds like I'm listening to the celebrity hosts of a Disney World parade at times... instead of good technical launch commentary. I suppose that's the only way networks can get a viewing audience now.

Ironically, you have to go to the CCTV Chinese state media launch coverage of Long March rockets for clear, non-'fluff' commentary (in English). Watched the liftoff of the Shenzhou 15 mission to the Tiangong station yesterday and it was no-frills but incisive, with a sole announcer/host and a technical expert on hand (they didn't appear on-air).
Nice onboard views and shots of the strap-on booster separations (which resulted in a 'cross' in the sky made up of the boosters and the core stage).

I miss Jack King. Couldn’t they synthesize his voice from past recordings and use an AI algorithm to assess the flight telemetry and provide commentary?
Or use the mission control voice from 2001.

There was a clean (no commentary) feed during the countdown available on NASA's media channel, which was streamed live on YouTube. The only (periodic) narration was by NASA commentator Derrol Nail, who I think did an admirable job providing technical data in a Jack King-like manner.
There should be more audio and video options for the Artemis II launch after NASA resolves some ITAR concerns that were unique to Artemis I and the way its LCC and MCC audio loops were configured.

On Dec. 5, NASA will air the lunar flyby of the Orion spacecraft on its return trek toward Earth.
The return powered flyby burn, in which the spacecraft will harness the Moon’s gravity and accelerate back toward Earth, is expected at 11:43 a.m. (1643 UTC) The spacecraft is expected to fly about 79 miles above the lunar surface at 11:42 a.m. (16:42 UTC) just before the burn.

I watched the entire broadcast and the press briefing later. What I got were three things:
The Apollo landing sites "fly-over" was, as expected, a bit of nonsense since Orion was far too high up to really call it a "fly-over."
The Earthrise at AOS was spectacular.
Apollo 10's speed record looks like it's going to be safe for a few more years.

For what its is worth:
The first image in Robert's post shows shows (lower right of center) the partially filled Prinz Crater with associated rilles. In mid-1969 this was one of the site candidates for the Apollo 19, or 20 mission. It was eventually replaced by Hadley-Apennine (Apollo 15).
The second image is of the Aristarchus Plateau, which includes Schroter's Valley, an early site candidate for Apollo 19.
The third image shows the Copernicus crater (lower center). Copernicus (either the north wall, or central peak) was considered (in 1969) as a candidate for the Apollo 16, 17, 18, and 20 missions. Even as late as mid-1971 it was in the running for the Apollo 16 and 17 mission landing site.
The fourth image shows part of Mare Imbrium. The filled crater Plato is in the upper left part of the image.

A cold front projected to move into the vicinity of the San Diego landing site has resulted in NASA replanning the splashdown for off the coast of Baja, California, where the weather conditions are expected to be better.

Those points are various splashdown points based on different contingencies, no? Is there information about the projected re-entry path for each of those (including the current planned one)? I live in Hawaii, and so if there's a chance of seeing the re-entry I would obviously certainly be interested.

All are along the same approach and begin with the same entry interface point. The other points are where the capsule is expected to land if it enters a ballistic entry, a direct entry (Apollo style), where the capsule will be in flight when it reaches its apogee, where it will fall if the skip is cut short and then its targeted landing site.
With regards to seeing the reentry, the panel at yesterday's press conference felt that it was unlikely anyone would see it because of the location but also because it is during the day. They said, if anything, someone might hear the sonic booms (but there was no mention of Hawaii).

It can now be revealed that NASA's Orion spacecraft, which now is just a day away from returning to Earth, carried secret messages to the moon.

Well done, NASA! It certainly looked like a text-book entry and splashdown - very impressive.
I realise they now have to analyse a ton of data to make sure everything worked as intended, but is it really necessary to wait two more years before launching a crew on Artemis 2? What factors (if any) dictate a "not earlier than late 2024" timeframe (which would almost inevitably slip into 2025 at best)? Would it be hardware construction; software integration; crew training; funding?
Put it another way: is there any fundamental barrier to NASA announcing shortly that everything went so well on Artemis 1 that Artemis 2 will launch in, say, early 2024?

A cost-saving decision was made several years ago to reuse the avionics boxes from Artemis I on Artemis II when it was thought that the latter would launch using the Exploration Upper Stage, allowing for more time to recertify the electronics. That plan changed (Artemis II will again use the ICPS upper stage as used on Artemis I).
Lockheed Martin needs about two years to test and recertify the avionics. They are now trying to reduce that time by moving forward new boxes that are being built for the Artemis III mission, but it is going to be tight to make late 2024.

I watched the coverage of the spacecraft recovery aboard the USS Portland. Taking the Artemis 1 onto the well deck as opposed to hoisting it out of the water onto an aircraft carrier just made so much more sense. Why didn't the Navy do that during Apollo?

Basically, there was no type of Navy ship at the time of Apollo that had the flooded well deck necessary to support spacecraft recovery operations.
The two existing amphibious assault ships, the USS Iwo Jima (LPH-2) and the USS New Orleans (LPH-11) did recover astronauts — Iwo Jima Apollo 13; New Orleans SL-3, SL-4 and ASTP — but in the traditional way (hoisting them aboard by crane to the hangar deck with the crew still inside).
When Orion begins to carry a crew, the astronauts will exit after the ammonia coolant bleed off is complete and will be airlifted by helicopter to the recovery ship as in Apollo.

Lockheed Martin designed Orion to be partially reusable. Its pressure vessel can be reused, as can most of its systems. The heat shield is single use only.
NASA has opted to only use new spacecraft for Artemis. The only reuse will be internal components.
