6:43 p.m.

Main engine cutoff of the SLS (Space Launch System) core stage is
complete, and the core stage has successfully separated from the interim cryogenic propulsion stage and the Orion spacecraft. This marks the end of
the first major propulsion phase of the Artemis II mission and the
transition to upper-stage operations.

The next major milestone is the deployment of the spacecraftAs SAWs (solar array wings) scheduled to begin approximately 18 minutes after launch.
Once extended, the four SAWs will provide continuous electrical power to
the spacecraft throughout its journey, supporting life-support systems, avionics, communications, and onboard operations. Deployment is a critical step in configuring Orion for the remainder of its time in Earth orbit and
for the outbound trip to the Moon.

6:38 p.m.

The spacecraft adapter jettison fairings that enclose the service module
and the launch abort system have separated from the Orion spacecraft. With
the rocket and spacecraft now flying above the densest layers of EarthAs atmosphere, Orion no longer requires the protective structures that
shielded it during the early, high-dynamic-pressure portion of launch.

The next major milestone is core stage separation and Interim Cryogenic Propulsion Stage ignition.

6:37 p.m.

The SLS (Space Launch System) twin solid rocket boosters have separated.
The boosters, each standing 177 feet tall and generating more than 3.6
million pounds of thrust at liftoff, provide most of the rocketAs power
during the first two minutes of flight and separation reduces mass and
allows the core stage to continue propelling the Orion spacecraft, named Integrity, toward orbit.

With the boosters now clear, the SLS core stage remains the primary source
of thrust.

In about one minute, the spacecraft adapter jettison fairings that enclose OrionAs service module and the launch abort system will separate from the spacecraft.

6:35 p.m.

NASAAsaArtemis II SLS (Space Launch System)arocket, with the
Orionaspacecraft atop carrying NASA astronauts Reid Wiseman, Victor
Glover, and Christina Koch, along with CSA (Canadian Space Agency)
astronaut Jeremy Hansen, lifted off from Kennedy Space CenterAs Launch
Complex 39B in Florida at 6:35 p.m. EDT to begin its journey to deep
space.

The twin solid rocket boosters ignited first, delivering more than 75% of
the thrust needed to lift the 5.75-million-pound rocket off the pad. Their combined power, along with the four RS-25 engines already at full thrust, generated an incredible 8.8 million pounds of force at liftoff. As the
rocket rose, the umbilicals u which provided power, fuel, and data
connections during prelaunch u disconnected and retracted into protective housings. This ensured the vehicle is free from ground systems and fully autonomous for flight.

The approximately 10-day Artemis II mission around the Moon is the first crewed flight under NASAAs Artemis campaign. It will help test the systems
and hardware needed to continue sending astronauts on increasingly
difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to continue building toward the first crewed
missions to Mars.

Below are the ascent milestones that will occur leading up to core stage separation. Times may vary by several seconds.

The Artemis II countdown has entered terminal count, and the ground launch sequencer has taken control, orchestrating a precise series of automated commands to prepare the SLS (Space Launch System) rocket and Orion
spacecraft for liftoff at a T-0 time of 6:35 p.m. EDT.

It was explained to me thus: the northern latitude of the launch
location means that, for least propellant use, the trip had to made when
the Moon is south of the celestial equator. At this time of the year,
that coincides with the Moon being closer to full than to new.

While this situation may have limited the astronauts' view of the Moon's
far side, on the other hand they saw a nice eclipse of the Sun by the
Moon, and an Earth entirely illuminated by Moonshine.
