@AkaSci For those not familiar with this, the next burn will be when Orion's elliptical orbit takes it close to the earth. The reason is that firing the engines for a fixed time will change its velocity by an amount Δv. For an initial velocity v, its kinetic energy will change to (1/2)m(v + Δv)² = (1/2)mv² + mvΔv + (1/2)m(Δv)². To reach the moon, you have to increase Orion's kinetic + potential energy, and the most efficient way to do that is when Orion's velocity is highest.

The serene view of the Pale Blue Crescent from the Artemis II Orion Integrity spacecraft this morning, now located 70,920 km away in its elliptical orbit, high above the Pacific Ocean, west of Peru, as the astronauts grab some sleep after a hectic day yesterday.

@AkaSci This means they’re out of the elliptical earth orbit and into lunar trajectory?

Integrity, the Artemis II Orion Integrity spacecraft, is located 71,245 km away, almost 2x the alt. of GSO, in a highly elliptical orbit, above the Pacific Ocean, west of Peru.
After reaching Apogee, it will turn around and execute a Perigee Raising Burn at around 8:15 a.m. EDT (12:15 UTC) and head back towards Earth.
12 hours later, at Perigee, it will execute the Translunar Injection Burn and shoot for the Moon.

There is some energy optimization related reason for this orbit and trajectory. Also, unlike uncrewed missions, this spacecraft needs to head for the moon within a day or two after launch.See post by @xChaos for some more info -

24/nArtemis II astronauts woke up this morning at 7:06 a.m. EDT with the song “Sleepyhead” by Young and Sick.
They then completed the perigee raise burn by igniting the Orion service module’s main engine for 43 seconds, which modified the trajectory to a 191x70133 km elliptical orbit. Perigee in another 12 hours or so.
The crew members will rest for another 4.5 hours before they are again awakened to start their first full day in space.

25/nArtemis II has a total of 28 camera systems, many for internal and external inspection and navigation, 4 located on each of Orion’s 4 solar arrays.
The fixed engineering cameras are primarily meant for in-flight inspection of the spacecraft. But they also opportunistically capture images of Earth and the moon in the background.
The astronauts carry two handheld Nikon D5 digital SLR 20.8 MP cameras for hi-res images and videos.

Yeah I see what you mean about the break-ups. Nice to ride along though!
