SouthernWorldwide.com – The Artemis II astronauts are embarking on their “crazy first day” in space following a successful and thrilling launch, shifting their focus to the critical tasks ahead in their historic lunar mission.
The crew will spend approximately 24 hours orbiting Earth. This period is dedicated to rigorously testing their Orion capsule. This marks the spacecraft’s second flight and its inaugural journey with a crew on board, underscoring the importance of ensuring its readiness.
The spectacular launch on Wednesday evening signifies a monumental achievement, representing the first crewed mission to the moon since the conclusion of the Apollo program 53 years ago.
The primary objective of the Artemis II mission is not to land on the moon or even enter lunar orbit. Instead, the crew’s trajectory involves looping around the moon, offering an unparalleled perspective of its far side. During this endeavor, the astronauts—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian Astronaut Jeremy Hansen—are poised to achieve a record, traveling farther from Earth than any human before them.
Before venturing towards the moon, the crew must meticulously evaluate their Orion capsule. This comprehensive testing is crucial for confirming the spacecraft’s capability to handle the demands of the mission.
Concurrently, the mission serves as a vital test for flight controllers and the established procedures necessary for safely returning astronauts to the moon for extended stays. These preparations are integral to NASA’s long-term vision of establishing a lunar base.
“This is a test flight,” stated NASA Administrator Jared Isaacman in an interview with CBS News. “This is the opening act in a series of missions that will send astronauts to and from the moon with great frequency as we return to stay.”
Following an eight-minute ascent into space on Wednesday, two firings of the upper stage engines propelled the astronauts into a highly elliptical orbit. This 24-hour orbit provides ample time for the crew to conduct thorough checks of the Orion capsule. The evaluations will focus on the proper functioning of the ship’s communications, navigation, propulsion, and life support systems.
“It is a crazy first day,” Wiseman shared with CBS News, highlighting the intensity of their initial hours in space.
“That one 24-hour orbit gives us time to check out all of (Orion’s) environmental control, life support systems,” Wiseman elaborated. “Can it scrub our carbon dioxide? Can it keep us alive? Can we drink water? Can we go to the bathroom? All those basic human functions.”
“We’ve got to go get those things tested before we press out to the moon,” he emphasized the critical nature of these checks.
Shortly after reaching orbit, Koch reported an issue with the capsule’s compact toilet system, which resembles a small telephone booth. She noted problems while activating the system.
A flight controller communicated, “Christina, with the toilet, the fault that you reported, the toilet cannot spin up. You can still use it for fecal collection, but you’ll have to use (contingency bags) for urine.”
The controller assured that engineers were developing a repair plan. Within approximately an hour, Koch successfully restored the toilet to its normal operational status.
A significant objective of the flight was achieved a little over three hours into the mission when Glover assumed manual control of the Orion capsule. This hands-on test is crucial for validating the spacecraft’s performance.
“We are essentially going to make sure that the vehicle flies the way that we think it does, that we designed it to do,” Glover explained the importance of this maneuver.
During the testing late Wednesday, Glover skillfully maneuvered the Orion capsule into formation with the upper stage that had propelled the ship into orbit. He described the thrusters’ operation as producing “a little rumble, like driving on a rocky road.”
The crew was scheduled to conclude their 18-hour day with two four-hour sleep periods early Thursday morning. Upon waking after the first rest period, they will monitor a firing of their service module engine to adjust their orbit. Subsequently, the crew will have another four-hour window for rest.
Meanwhile, NASA’s mission management team will meticulously review Orion’s performance up to that point. If all systems are functioning as expected, the spacecraft will be declared “go” for the critical “trans-lunar injection,” or TLI, engine firing.
The TLI burn, a planned six-minute maneuver expected Thursday evening at the spacecraft’s orbital apogee, will significantly increase its velocity by approximately 900 mph. This boost will propel the ship out of Earth orbit and set it on course for the moon.
This TLI burn will place the Orion on a free-return trajectory. As the spacecraft orbits the moon, lunar gravity will alter its path, guiding it back towards a precisely targeted splashdown in the Pacific Ocean off the coast of Southern California on April 10.

The journey to the moon is anticipated to take approximately four days. On Monday, the astronauts will enter the “lunar sphere of influence,” where their speed will gradually increase as the moon’s gravitational pull begins to overcome Earth’s.
Later that day, the spacecraft is projected to reach a distance of about 248,650 miles from Earth, a figure that will equalize and then surpass the record set by the Apollo 13 crew in 1970. The exact distance will be confirmed as the mission progresses.
The Orion capsule will pass behind the leading edge of the moon, temporarily losing contact with mission control for approximately 40 minutes on Monday evening. As the spacecraft sails over the far side of the moon, the astronauts will approach within about 4,100 miles of the lunar surface at their closest point. Their maximum distance from Earth during this phase will reach approximately 252,800 miles.
While traversing the far side of the moon, approximately a quarter of the lunar surface will be illuminated by the sun. This will provide the astronauts with a unique opportunity to observe and document features never before witnessed by human eyes, capturing photographs and videos.
“We are going to maximize every minute of looking at that far side,” Koch stated, emphasizing the scientific value of this observation period. “There are launch windows where we could have illumination that will allow us to see things for the first time ever with human eyes, and that actually makes a difference to the people doing the scientific data analysis.”
Glover added, “Twenty-four men have seen the moon, and we’re going to send the first set of woman’s eyes. They think that she can potentially see colors that we may not see. And so I think that’s also very important.”
Following their passage around the far side, the crew will re-emerge into view from Earth, re-establishing communication with mission control in Houston. The spacecraft will depart the lunar sphere of influence on Tuesday afternoon, commencing its return journey to Earth. As it approaches our planet, its speed will steadily increase due to Earth’s gravitational pull.
Next Thursday, April 9, the astronauts are scheduled to attempt a ship-to-ship call with the crew of the International Space Station. This will be followed by a crew news conference later that afternoon. These events will set the stage for the reentry on Friday, April 10.
During reentry, the Orion capsule will orient itself heat shield forward, impacting the upper atmosphere at approximately 25,000 mph. The heat shield will endure temperatures reaching up to 5,000 degrees Fahrenheit as the spacecraft rapidly decelerates through atmospheric friction.
Once the zone of maximum heating is traversed, the capsule’s descent velocity will significantly decrease to around 300 mph. A series of parachutes will deploy sequentially, slowing the craft to a relatively gentle splashdown speed of 15 mph.
Navy crews will be on standby to assist the astronauts in exiting their spacecraft and to provide short helicopter transfers to a nearby recovery ship.
“I think Jeremy said it best, when that hatch opens on the Pacific Ocean, we’ll probably be pretty ready to get out,” Koch remarked. “But a part of us will know that there are some moments left that we will miss forever and probably won’t ever get to have back.”
The Orion capsule will be brought aboard, while the astronauts, after undergoing medical checks and communicating with family and friends, will be transported ashore. From there, they will take a flight back to the Johnson Space Center for debriefing, more extensive medical examinations, and family reunions.
With the Artemis II crew safely returned to Earth, NASA’s attention will pivot to the Artemis III mission and subsequent endeavors. The agency will focus on preparing for another Orion crew to test rendezvous and docking procedures next year with one or both moon landers currently under development by SpaceX and Blue Origin.
If these preparations are successful, NASA plans to launch one, and potentially two, moon landing missions in 2028.
“It’s important because we’re fulfilling a promise… for America’s return to the moon as a stepping stone for all the things that we are going to do farther out into our solar system, like some day American astronauts planting the stars and stripes on Mars,” NASA Administrator Jared Isaacman articulated in his interview with CBS News.
“So you’re doing it for the scientific potential, the economic potential as a technological proving ground to do the things on the moon that you’re going to need on Mars.”
“And how about inspiring the next generation?” he added. “How many kids after this mission are going to dress up as astronauts for Halloween and want to grow up and contribute to this great adventure?”
