During a press conference on Friday, NASA leaders said the Artemis II crew is in "great spirits" and "really excited about the opportunity to be there and what's going on."

Orion's navigation and propulsion systems are performing so well that thew crew will not perform the planned trajectory burn scheduled for this evening, NASA said.

"I think it's really good to see that we don't need these minor correction burns. It shows that our navigation performance and our ability to get ranging has been outstanding," Howard Hu, program manager for the Orion spacecraft, said

On Friday, the astronauts spent some time conducting a "noise characterization" assessment of the toilet's noise levels.

The crew also had time to exercise and did a CPR demonstration. NASA said the astronauts are conducting a medical kit evaluation and will test emergency communications with the Deep Space Network.

The Artemis II astronauts woke up around 1:00 p.m. ET on day 3 of their mission to the moon.

"Whenever you want to do some wake-up music, we can do some post-wake-up music," mission commander Reid Wiseman told Mission Control.

NASA's Mission Control in Houston played "In a Daydream" by the Freddy Jones Band.

Day 3 will include demonstrating CPR procedures in space and checking out some of Orion's medical kit, including the thermometer, blood pressure monitor, stethoscope and otoscope, according to NASA.

The crew will also begin to configure the cabin for its upcoming lunar flyby so it has the most ideal setup for capturing images and data of the far side of the moon.

Additionally, the Artemis II astronauts will be doing a Deep Space Network emergency communications test make sure the system works.

NASA released the first batch of high quality photos of Earth taken from the Orion capsule.

The images show the crew’s view as they look back at the pale blue dot we call home, while continuing their journey toward the moon.

According to NASA, the images were taken on Artemis II commander Reid Wiseman's "personal computing device, PC or tablet."

During Friday morning's video feed from the Orion spacecraft, NASA captured an image of Earth partly in daytime and partly at night.

The Earth is the object on the right that appears crescent-shaped. Orion is about 77,000 miles from Earth here.

Overnight, the Artemis II crew wrapped up a busy stretch of work in deep space, including a hands-on test of Orion's controls and more prep for Monday's lunar flyby.

According to NASA, the crew began a manual piloting demonstration at 9:09 p.m. ET, with mission specialists Christina Koch and Jeremy Hansen taking turns flying the spacecraft.

For about 41 minutes, they tested how Orion responds in different thruster modes to see how it handles both full, free movement and more limited steering. The goal is to give engineers a better sense of how the spacecraft performs when astronauts are actively flying it, NASA said.

NASA said the test is part of a series of evaluations, with commander Reid Wiseman and pilot Victor Glover expected to run a similar demonstration later in the mission -- on April 9 -- to give teams on the ground more data from different pilots.

Earlier in the day, the crew also spent time going over their plan for the lunar flyby. According to NASA, they reviewed a list of specific features on the moon's surface that scientists want them to photograph and describe.

That work will come into play on Monday, when Orion begins its flyby at 2:45 p.m. ET.

All of this is setting the stage for one of the most anticipated parts of the mission: when astronauts will see the moon up close and help document it in real time for scientists back on Earth.

The crew shared a new photo of the moon during day 4 of their mission, capturing parts of the lunar far side including Orientale basin peeking through from the right side of the lunar disk.

"This mission marks the first time the entire basin has been seen with human eyes," NASA said in an Instagram post.
