Virtually as tall as a soccer box, NASA’s Area Release Gadget rocket and pill stack traveled slowly – just below 1 mile according to hour – out to the Artemis II launchpad, its brief house on the Kennedy Area Heart in Florida, on Jan. 17, 2026. That gradual move slowly is in stark distinction to the height speed it is going to achieve on release day, over 22,000 miles according to hour, when it is going to ship a team of 4 on a adventure across the Moon.
A rocket release is at all times on the mercy of quite a lot of components outdoor of the release group’s regulate – from the literal place of the planets all the way down to flocks of birds or rogue boats close to the launchpad. Whilst Artemis II is recently deliberate for March 2026, it would possibly not release till later in April. If truth be told, March already represents a small extend from the to start with estimated February release alternative.
Artemis II’s purpose is to ship folks to go by way of the Moon and be sure that all engineering techniques are examined in area ahead of Artemis III, which can land astronauts close to the lunar south pole.
If Artemis II is a hit, it is going to be the primary time anyone has been again to the Moon since 1972, when Apollo 17 left to go back to Earth. The Artemis II astronauts will fly by way of the a ways facet of the Moon ahead of returning house. Whilst they gained’t land at the floor, they’ll give you the first human eyes at the lunar a ways facet for the reason that twentieth century.
To place this in point of view, no person beneath the age of about 54 has but lived in an international the place people have been that a ways clear of Earth. The 4 astronauts will orbit the Moon on a 10-day voyage and go back via a splashdown within the Pacific Ocean. As a planetary geologist, I’m excited for the chance of folks ultimately returning to the Moon to do fieldwork at the first stepping stone clear of Earth’s orbit.
A walkthrough of the Artemis II undertaking, which plans to take a team across the Moon.
Why gained’t Artemis II land at the Moon?
If you happen to sought after to summit Mount Everest, you might first take a look at out your apparatus and take a look at to ensure the whole thing works ahead of heading up the mountain. A lunar touchdown is identical. Checking out all of the elements of the release device and team automobile is a important a part of returning folks safely to the skin of the Moon after which flying them again to Earth.
And in comparison to the lunar floor, Everest is a tropical paradise.
NASA has completed lunar landings ahead of, however the 54-year hiatus implies that lots of the engineers who labored on Apollo have retired. Most effective 4 of the 12 astronauts who’ve walked at the Moon are nonetheless alive.
Generation now may be hugely other. The Apollo lunar touchdown module’s pc best had about 4 kilobytes of RAM. A unmarried standard iPhone photograph is a couple of megabytes in dimension, over 1,000 instances greater than the Apollo lunar touchdown module’s reminiscence.
The 2 elements of the Artemis II mission are the rocket (the Area Release Gadget) and the team pill. Each have had an extended highway to the launchpad.
The Orion pill used to be advanced as a part of the Constellation program, introduced in 2005 and concluded in 2010. This program used to be a President George W. Bush-era try to transfer folks past the gap travel and Global Area Station.
The Area Release Gadget began construction within the early 2010s in its place automobile for the Ares rocket, which used to be supposed for use with the Orion pill within the Constellation program. The SLS rocket used to be utilized in 2022 for the Artemis I release, which flew across the Moon with out a team. Boeing is the principle contractor tasked with construction the SLS, even though over 1,000 separate distributors had been concerned within the rocket’s fabrication.
The Apollo program, too, first despatched a crewed pill across the Moon with out touchdown. Apollo 8, the primary crewed spacecraft to go away Earth orbit, introduced and returned house in December 1968. William Anders, one of the crucial astronauts on board tasked with trying out the elements of the Apollo lunar spacecraft, captured the long-lasting “Earthrise” symbol throughout the undertaking.

“Earthrise” used to be the primary time folks have been in a position to seem again on the Earth as a part of a spacefaring species. The Earthrise symbol has been reproduced in quite a lot of contexts, together with on a U.S. postage stamp. It basically reshaped how folks considered their atmosphere. Earth continues to be a ways and past essentially the most liveable location within the sun device for lifestyles as we comprehend it.
Distinctive Artemis II science
The Artemis II astronauts would be the first to peer the lunar a ways facet for the reason that ultimate Apollo astronauts left over 50 years in the past. From the window of the Orion pill, the Moon will seem at its biggest to be in regards to the dimension of a seashore ball held at arm’s period.
During the last many years, scientists have used orbiting satellites to symbol a lot of the lunar floor. A lot imaging of the lunar floor has been completed, particularly at top spatial answer, by way of the lunar reconnaissance orbiter digital camera, LROC.
LROC is made up of a couple of other cameras. The LROC’s large attitude and slender attitude cameras have each captured pictures of greater than 90% of the lunar floor. The LROC Vast Perspective Digicam has a answer at the lunar floor of about 100 meters according to pixel – with every pixel within the symbol being in regards to the period of an American soccer box.
The LROC slender attitude digital camera supplies about 0.5 to two meters according to pixel answer. This implies the typical individual would have compatibility inside of in regards to the period of 1 pixel from the slender attitude digital camera’s orbital pictures. It might obviously see massive rocks and the Apollo lunar touchdown websites.

If the robot LROC has coated lots of the lunar floor, why must the human team of Artemis II take a look at it, at decrease answer?
Maximum pictures from area don’t seem to be what can be regarded as “true” colour, as noticed by way of the human eye. Identical to how the footage you are taking of an aurora within the night time sky with a cellular phone digital camera seem extra dramatic than with the bare eye, the picture is dependent upon the wavelengths the detection techniques are delicate to.
Human astronauts will see the lunar floor in several colours than LROC. And one thing that human astronauts have that an orbital digital camera device can’t have is geology coaching. The Artemis II astronauts will make observations of the lunar a ways facet and virtually immediately interpret and regulate their observations.
The continuing undertaking, Artemis III, which can come with astronauts touchdown at the lunar floor, is recently scheduled to release by way of 2028.
What’s subsequent for Artemis II
The Artemis II team pill and SLS rocket at the moment are ready at the launchpad. Ahead of release, NASA nonetheless wishes to finish a number of ultimate assessments, together with trying out techniques whilst the rocket is fueled. Those techniques come with the emergency go out for the astronauts in case one thing is going incorrect, in addition to safely transferring gas, which is made from hydrazine – a molecule made up of nitrogen and hydrogen this is extremely energy-dense.
Finishing those assessments follows the previous aerospace adage of “test like you fly.” They’re going to make sure that the Artemis II astronauts have the whole thing running at the flooring ahead of departing for the Moon.
Editor’s observe: This newsletter used to be up to date on Feb. 3, 2026, to constitute the following imaginable release window moving into March.
