NASA's Artemis II mission to the Moon will now launch in March 2026 at the earliest, having been pushed back as a result of issues that arose during its wet dress rehearsal this week.

The space agency had been targeting 8 February at the earliest for the launch of the mission, but this has now been delayed following culmination of a practice run-through of launch protocols.

The four astronauts of the Artemis II crew have also been released from quarantine: a sign that the Artemis II potential launch date has been postponed from a matter of days to a matter of weeks.

Wet dress rehearsal
As of 2 February 2026, NASA engineers and the ground team concluded the Artemis II 'wet dress rehearsal', which is a run-through of launch procedures, including practising loading fuel into the Space Launch System (the rocket) and a simulated countdown.

The wet dress rehearsal was conducted at Kennedy Space Center in Florida without the Artemis II astronauts – Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen – on board.

At the time of this first wet dress rehearsal, all four astronauts were undergoing quarantine in Houston, Texas, which is standard procedure that begins as the proposed launch date approaches.

Firstly, NASA says, cold weather at Kennedy Space Center caused a delay in the wet dress rehearsal getting started.

Then, as they were loading fuel into the rocket's tank, engineers noticed a leak in the system.

This led to an automatic halt of the practice countdown with just 5 minutes to go.

Other issues arose during the rehearsal, including the need to readjust a valve that's associated with the pressurisation of the Orion crew module hatch.

The Orion module is the space capsule where the Artemis II astronauts will be enclosed on their journey around the Moon.

NASA says cold weather also caused issues with cameras and other equipment, and there are ongoing communications problems affecting the ground team.

The astronaut crew have been released from their quarantine, and NASA has said Artemis II will now launch in March 2026 at the earliest.

Is the fuel leak a big deal?
A fuel leak on a rocket that's about to take humans further into space than ever before might sound like a huge problem, but just how much of an issue is it?

NASA Administrator Jared Isaacman took to social media channel X to say: "With more than three years between SLS launches, we fully anticipated encountering challenges.

"That is precisely why we conduct a wet dress rehearsal. These tests are designed to surface issues before flight and set up launch day with the highest probability of success."

In other words, if something as serious as a fuel leak is going to happen to the Artemis II rocket, it's better that it happens during practice, rather than causing a countdown abort on launch day itself.

But liquid hydrogen fuel leaks like these are ultimately what plagued the Artemis I mission, which launched in November 2022 and which marked the first flight of the Artemis programme.

And while Artemis I was a success, it was after all an un-crewed test flight.

Now that NASA is preparing to launch Artemis II, the first crewed mission of the programme, the discovery of a fuel leak during the first dress rehearsal is all the more significant.

For a while, it felt like Artemis II was indeed going to launch in early February. With the crew in quarantine and the wet dress rehearsal beginning pretty much as scheduled, many of us were hoping we wouldn't need to wait too long.

But, as NASA will undoubtedly repeatedly point out, this is why wet dress rehearsals are important, and why the launch procedure needs to run smoothly, all creases ironed out.

As Isaacman put it on X: "As always, safety remains our top priority, for our astronauts, our workforce, our systems, and the public.

"We will only launch when we believe we are as ready to undertake this historic mission."

Artemis III lunar lander possibilities for making the moon landing occur before 2030
So anyone familiar with the program knows that the lander is the critical path at this point (assuming Artemis II goes well).

The suits seem to be coming along, SLS and Orion look ready, that just leaves the lander.

The possible options as I understand them are:

Starship HLS is completed, orbital refueling occurs - This is the original plan and as far as I know is still the plan

Blue origin adapts their MK I lander(much simpler than HLS) and uses new Glenn to launch it

Spacex makes an expendable starship, simplifying the launch process and eliminating the need for orbital refueling required

Any options I missed? Which one is the best course of action? Is nasa considering any of these? It seems to me they’re really pushing for making the lunar launch happen in 2028

Blue Origin / New Glenn is nog het meest waarschijnlijk.

De twee grootste problemen zijn, dat de SLS mee moet doen (die is niet krachtig genoeg) en dat je nu van NASA de hele lander weer moet laten opstijgen (geen afval op de maan), waardoor die veel groter moet zijn (hij heeft meer brandstof nodig om op te stijgen en daardoor ook om te landen, waardoor ook de draagraket meer brandstof nodig heeft).

Engineers ran into problems repressurizing the Artemis 2 moon rocket’s upper stage helium tanks overnight Friday, a problem that will require rolling the huge rocket off the launch pad and back to its processing hangar for troubleshooting. The work will push the already delayed mission from March to at least early April, officials said Saturday.

Pressurized helium is used to push propellants to rocket engines for ignition and to purge various fuel lines to clear them out before propellants flow. It’s not yet known what might be preventing helium to flow back into the SLS rocket’s upper stage following a successful countdown rehearsal test that ended Thursday.

“Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB (Vehicle Assembly Building),” NASA Administrator Jared Isaacman said in a post on the social media platform X. “We will begin preparations for rollback, and this will take the March launch window out of consideration.”

The Artemis 2 mission aims to send four astronauts – Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen – on a flight around the far side of the moon and back to thoroughly test the agency’s Orion deep space capsule to help clear the way for a lunar landing mission, Artemis 3, in 2028.

Because of the ever-changing positions of the Earth and moon, and associated changes in lighting and other factors, only a handful of launch opportunities are available each month that meet the Artemis 2 mission requirements. The current launch period ends on March 11. The available launch dates next month are April 1, 3, 4, 5 and 6.

Wiseman, Glover, Koch and Hansen originally hoped to launch early this month, but hydrogen leaks detected during an initial “wet dress countdown” rehearsal ultimately pushed the flight to March.

NASA completed a second fueling test and countdown Thursday, loading the Space Launch System rocket with more than 750,000 gallons of liquid oxygen and hydrogen fuel while working through the steps that will be needed to actually launch the huge rocket on the long-awaited mission.

The test went well, there were no fuel leaks like the ones that derailed plans for a launch earlier this month. Managers said Friday the team would press ahead for a launch attempt on March 6 to send Wiseman and his crewmates to the moon.

Hoping for the best, the astronauts went into pre-flight medical quarantine at the Johnson Space Center Friday evening and planned to fly to the Kennedy Space Center on March 1 to prepare for launch. They now will leave quarantine to await developments.

“I understand people are disappointed by this development,” Isaacman said. “That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks.

“There are many differences between the 1960s and today, and expectations should rightfully be high after the time and expense invested in this program.

“I will say again, the President created Artemis as a program that will far surpass what America achieved during Apollo. We will return in the years ahead, we will build a Moon base, and undertake what should be continuous missions to and from the lunar environment. Where we begin with this architecture and flight rate is not where it will end

Plans to return humans to the moon will come in later
mission as agency grapples with delays and glitches

Nasa announces Artemis III mission no longer aims to send humans to moon
Plans to return humans to the moon will come in later mission as agency grapples with delays and glitches

Nasa announced on Friday radical changes to its delayed Artemis III mission to land humans back on the moon, as the US space agency grapples with technical glitches and criticism that it is trying to do too much too soon.

The abrupt shift in strategy was laid out by the space agency’s recently confirmed administrator, Jared Isaacman. Announcing the changes on Friday, he said that Nasa would introduce at least one new moon flight before attempting to put humans back on the lunar surface for the first time in more than half a century, in 2028.

The new, more incremental approach would give the Nasa team a chance to test flight and refine its technology. As part of the changes, the Artemis II mission to fly humans around the moon this year, without landing, would also be pushed back from its latest scheduled launch on 6 March to 1 April at the earliest.

“Everybody agrees this is the only way forward,” Isaacman told reporters at a news conference. “I know this is how Nasa changed the world, and this is how Nasa is going to do it again.”

The revised course came as Nasa has been wrestling with a number of delays and technical problems. Earlier this week, the independent body that reviews space safety issued a blunt report sharply criticising the space agency’s current plans as too risky.

The aerospace safety advisory panel recommended that Nasa rethink its objectives for Artemis III, which had been conceived as the first human landing on the moon since the final flight in the Apollo series in December 1972. The panel said that the call for a revision was urgent, “given the demanding mission goals”.

Isaacman said that under the new plan, the eventual moon landing would be achieved through evolutionary steps rather than big leaps in technological procedures. “We’re going to get there in steps, continue to take down risk as we learn more and we roll that information into subsequent designs,” he told CBS News.

He added: “We’ve got to get back to basics.”

Step one in the revised schedule is the launch of the Artemis II moon mission, which has been plagued by delays. The rocket was returned to its hangar at the Kennedy Space Center in Florida earlier this week.

Engineers had discovered a blockage in the rocket’s helium flow in the upper stage of the booster.

The latest delay followed disappointment in February, when Nasa was forced to put off the launch of Artemis II after hydrogen was found leaking from its Space Launch System rocket.

Artemis II will send four astronauts on a 10-day journey around the moon, designed to take people further into space than ever before, beyond the record set by Apollo 13 in 1970.

Isaacman said on Friday that additional missions would then be included in the schedule. He likened the extra steps to the approach taken in Nasa’s original moon landing in which Neil Armstrong and Buzz Aldrin first stepped on to the lunar surface in 20 July 1969.

That legendary event was hazarded only after three separate moon missions had been completed.

The Artemis III mission will no longer aim to land on the moon. Instead, under the revised plans, it will be launched by mid-2027 as a low-Earth orbit designed to test essential technologies.

That extra stage is intended to give Nasa extra flight experience with the massively complex advanced systems and the chance to test its space vehicles before it attempts a human moon landing. Should all that go to plan, then a new Artemis IV mission would set out in 2028 to land on the moon.

The eventual aspiration is to land astronauts near the moon’s south pole. A second moon landing, Artemis V, could be conducted in 2028, followed by a moonshot attempted each year thereafter, Nasa said.

As NASA invites the public to follow the Artemis II mission as a crew of four astronauts venture around the Moon inside the agency's Orion spacecraft, people around the world can pinpoint Orion during its journey using the Artemis Real-time Orbit Website (AROW).

During the approximately 10-day mission, NASA will test how the spacecraft's systems operate as designed with crew aboard in the deep space environment. Using AROW, anyone with internet access can track where Orion and the crew are, including their distance from Earth, distance from the Moon, mission duration, and more. Access to AROW is available on:

quote:

Using AROW, the public can visualize data that is collected by sensors on Orion and then sent to the Mission Control Center at NASA's Johnson Space Center in Houston during its flight. It will provide constant information using this real-time data beginning about one minute after liftoff through Orion's atmospheric reentry to Earth at the end of the mission.



Online, users can follow AROW to see where Orion and the crew are in relation to the Earth and the Moon and follow Orion's path during the mission. Users can view key mission milestones and characteristics on the Moon, including information about landing sites from the Apollo program.

The mobile app includes similar features to the website, with the addition of augmented reality tracker. After a brief calibration sequence, on-screen indicators will direct users where to move their phone to see where Orion currently is relative to their position on Earth. Mobile app tracking will be available once Orion separates from the rocket's upper stage, approximately three hours into the mission.

State vectors, or data that describes precisely where Orion is located and how it moves, also will be provided by AROW, following a proximity operations demonstration to evaluate the manual handling qualities of Orion.

These vectors can be used for data lovers, artists, and creatives to make their own tracking app or data visualization. Also available for download will be trajectory data from the flight, called an ephemeris, found at the bottom of this page, after the mission begins. The ephemeris data can be used to track Orion with your own spaceflight software application or telescope, or to create projects such as a physics model, animation, visualization, or tracking application.

Artemis II, the agency's first crewed mission in the Artemis campaign, is a key step in NASA's path toward establishing a long-term presence at the Moon and confirming the systems needed to support future lunar surface exploration and paving the way for the first crewed mission to Mars.
