That mission will set the stage for [Artemis 3](https://www.space.com/artemis-3-moon-landing-mission), the first crewed lunar landing, in 2025.

The uncrewed mission will send a sensor-laden Orion capsule on a 42-day shakedown cruise around [the moon](https://www.space.com/55-earths-moon-formation-composition-and-orbit.html) to verify that that both vehicles are ready to fly astronauts into deep space. EDT (1233 GMT) on Monday from Pad 39B here at NASA's [Kennedy Space Center](https://www.space.com/17705-nasa-kennedy-space-center.html). If NASA cannot launch Artemis 1 on Monday, the agency could try again on Sept. "I will say my thoughts are really grateful tomorrow," Spaulding said, adding that the entire NASA launch team is excited after years of work.

If all goes according to plan, the Artemis 2 mission will send astronauts into lunar orbit in 2024. An upper stage will send it on its way to the moon. Showers are predicted early in the day, according to The Weather Channel. Weather permitting, the Artemis 1 mission is scheduled to lift off sometime during a two-hour launch window that opens on Monday at 8:33 a.m. This is a test mission that will put both the booster and the Orion capsule, which will eventually carry astronauts through its paces. 29, NASA is scheduled to start the process of getting people back there.

The Artemis 1 mission is a test flight of massive importance. The launch, scheduled for Monday, will see an unmanned Orion module put into orbit around the Moon ...

We're going to learn a lot from this test flight". With a long-term presence established on or around the Moon, it would then be used for future missions further afield, including to Mars. You can say 'I worked on that rocket' and they're working on the second one and the third one and fourth one and the fifth one," said Lonnie Dutreix, director of Michoud Assembly Facility in New Orleans. NASA will launch an unmanned Orion spacecraft into orbit around the Moon on a test run to ensure manned missions are as safe as possible. The Artemis 1 mission is a test flight of massive importance. This will be the first crewed lunar landing since Apollo 17 in 1972.

The launch of the biggest and most powerful rocket ever built is scheduled to happen this evening from the same launch pad used by the last Apollo mission ...

"The goal is not to send people to the Moon and stay there, the goal is to do a transit between the lunar gateway and land on the Moon and start building whatever you need to build on the moon," Dr Vignelles said. Two of the shoe-box satellites on the Artemis 1 mission will map water at the south pole, and another will trial landing technology. In 2025, NASA plans to land the first woman and first person of colour near the Moon's south pole on Artemis 3. This flight will use an even more powerful version of the SLS rocket to lift the crew and cargo off the ground. Artemis 1 is the first of a number of missions. "Orion will be taking selfies down its solar wings of itself in the foreground, the Moon in the background and Earth [460,000km] away." Without the protection of Earth's magnetic field, astronauts travelling to the Moon will be exposed to more intense radiation, for much longer, than a trip to the International Space Station. The top half of the rocket and capsule then take about two hours to do a lap of Earth, while the solar panels on the capsules unfurl. If it doesn't burn up in the first phase, it will deploy parachutes and splash down in the Pacific off the coast of California on October 10. The 42-day journey will not only push the brand new rocket and capsule to the limit, it will test a new orbit, and go further than a craft capable of taking a crew further beyond the Moon has ever been before. Perched on top of the 32-storey-high rocket is a new space capsule set to fly beyond the Moon and back again. The big test will be how the rocket and capsule integrate with each other and communicate with the ground station, said Aude Vignelles, chief technology officer with the Australian Space Agency, which is signed to the Artemis program but not involved with the launch.

“It's really to learn how we can go further,” said Isabelle Tremblay of the Canadian Space Agency, which is playing a big role in the Artemis missions. “It's ...

“The moon has become a strategic objective,” said Tremblay. “It’s really to learn how we can go further,” said Isabelle Tremblay of the Canadian Space Agency, which is playing a big role in the Artemis missions. That’s where Canada’s main contribution to the Artemis program will shine. But the Artemis missions aim to go beyond Earth’s satellite to build the Lunar Gateway. Artemis 2 will orbit the moon and astronauts in Artemis 3 will land on it. The mission is to deposit 10 scientific satellites in lunar orbits, but the main thrust is to test NASA’s new launch system and Orion spacecraft for Artemis 2.

If all goes to plan, Orion will make its closest pass of the moon this Saturday and overshoot it, then settle into orbit and return to Earth in October.

president Barack Obama launched the Artemis program in 2010, setting 2033 as a target date for humans on Mars. This reflects the technological and scientific momentum Artemis aims to harness, after the failure of the Constellation program, with also tried to go back to the moon. “It’s no longer the Apollo generation, it’s the Artemis generation,” said Bill Nelson, NASA Administrator, at a pre-launch press briefing. The real prize, though, is a Mars shot, still at least more than a decade away. The high-tech crash test dummies — properly spelled “manikins” in this scientific context and named Zohar, Helga and, in the captain’s chair, Commander Moonikin Campos — have been equipped with sensors for everything from vibration to radiation.

Mais il se révèle également crucial pour la propulsion car ce sont ses moteurs qui corrigeront la trajectoire de l’engin lors du voyage et qui lui permettront de s’insérer en orbite lunaire puis d’en ressortir lorsque l’heure du retour aura sonné. Ce ne sera pas encore l’heure du grand spectacle puisque cette mission, qui s’envolera du pas de tir 39B du Centre spatial Kennedy (Floride), ne se posera pas sur la Lune et s’effectuera sans équipage. A commencer par la fusée, un lanceur lourd connu sous le nom de Space Launch System (SLS), lointain successeur de la Saturn-5 du programme Apollo.

Le décollage doit avoir lieu à 14 h 33, heure de Paris, depuis la Floride. La mission Artemis-1 doit marquer le lancement du programme américain de retour ...

Puis, au bout d’environ 1 h 30, une dernière poussée de l’étage supérieur mettra la capsule sur le chemin de la Lune, qu’elle mettra plusieurs jours à atteindre. La prochaine date de décollage possible est le 2 septembre. Les femmes représentent 30 % des effectifs en salle de lancement - contre une seule à l’époque d’Apollo 11. Du haut de ses 98 mètres, la fusée orange et blanche SLS ne pourra pas décoller en cas de pluie ou d’orages. La météo est à 80 % favorable pour un lancement à l’heure, au début de la fenêtre de tir qui s’étend sur deux heures.

The leak popped up during overnight fueling of the most powerful rocket NASA has ever built ahead of a scheduled morning liftoff and start of a new mission ...

Engineers also will test the crew ship's myriad systems in deep space and make sure its heat shield can protect returning astronauts from the 5,000-degree heat of re-entry. The SLS rocket's core stage must be loaded with 196,000 gallons of liquid oxygen and 537,000 gallons of hydrogen for takeoff. It was not immediately clear what impact the weather-related fueling delay and the hydrogen troubleshooting might have on the eventual launch time, assuming the problem can be fixed before the end of a two-hour launch window. The leak developed in a launch pad service structure where propellants are fed into the rocket's core stage through umbilicals designed to ensure a tight seal until the moment of liftoff when they are retracted. All that propellant will feed the core stage's four shuttle-era engines. Leaks are potentially dangerous, and sensors monitor concentrations to make sure safety limits are not violated.

Mia Lynch, once a proud member of the Royal Canadian Navy, says her pride turned into pain not long after enlisting. At the time of the death, there was no ambulance service in the town. Regardless of all the technical snags, thunderstorms ultimately would have prevented a liftoff. Engineers scrambled to understand an 11-minute delay in the communication lines between launch control and Orion that cropped up late Sunday. A two-person lunar landing could follow by the end of 2025. Even though no one was on board, thousands of people jammed the coast to see the rocket soar. The rocket was set to lift off on a flight to propel a crew capsule into orbit around the moon. Then, NASA ran into new trouble when it was unable to properly chill one of the rocket's four main engines, officials said. As precious minutes ticked away Monday morning, NASA repeatedly stopped and started the fuelling of the Space Launch System rocket because of a leak of highly explosive hydrogen, eventually succeeding in reducing the seepage to acceptable levels.

Le développement d’autres versions de la fusée capables d’apporter des charges utiles plus importantes a été mis en pause face à ces difficultés. Orion doit pouvoir s’aventurer plus de 60 000 kilomètres derrière La Lune, soit la plus grande distance parcourue par un engin habité. En comparaison, dans sa version finale, la Falcon 9 de SpaceX – qui sert notamment à ravitailler l’ISS – mesure 70m de haut, pour 595 tonnes et peut emmener plus de 22 tonnes de charge utile, mais seulement en orbite basse. Un problème au niveau d’un des moteurs du module central de la fusée a entraîné une annulation de la tentative. Le SLS, qui permettra l’accomplissement des missions vers la Lune du programme Artemis, doit être déployé pour la première fois; cela explique les précautions prises par la NASA. Pendant la nuit, le remplissage des réservoirs a pris du retard en raison des conditions météo.

An apparent hydrogen leak and some balky weather were among issues concerning engineers during overnight fueling of the most powerful rocket NASA has ever ...

But as it turned out, the frost was caused by a minor stress crack in the tank's insulation and was not a problem for launch. That prompted additional troubleshooting, including increasing the pressure in the line, but to no avail. Engineers also will test the crew ship's myriad systems in deep space and make sure its heat shield can protect returning astronauts from the 5,000-degree heat of re-entry. But after working through a weather delay and a brief indication of a hydrogen leak, trouble cooling one of the rocket's main engines forced managers to call off the countdown. Based on the constantly changing positions of the Earth and moon, only one other opportunity is available after that — September 5 at 5:12 p.m. NASA carried out four dress rehearsal countdowns and fueling tests leading up to Monday's attempt, and all four encountered problems. That's the purpose of a test flight." NASA reported three of the engines were being properly conditioned, but engine No. After a 55-minute delay, the six-hour fueling process finally got underway at 1:14 a.m. "This is just part of the space business, and it's part of, particularly, a test flight," Nelson said. EDT, two minutes after the two-hour launch window opened at 8:33 a.m. But it was not to be.

A two-person lunar landing could follow by the end of 2025. As precious minutes ticked away Monday morning, NASA repeatedly stopped and started the fueling of the Space Launch System rocket with nearly 1 million gallons of super-cold hydrogen and oxygen because of a leak of highly explosive hydrogen. Then, NASA ran into new trouble when it was unable to properly chill one of the rocket’s four main engines, officials said.

Puis, au bout d'environ 1 h 30, une dernière poussée de l'étage supérieur mettra la capsule sur le chemin de la Lune, qu'elle mettra plusieurs jours à atteindre. Après des tests, le flot a finalement repris et les équipes ont continué à suivre de près la situation. La NASA souhaite ensuite lancer environ une mission par an. En cas de nouvel échec, le vol serait reporté à la fin du mois. Des microsatellites seront également déployés pour aller étudier la Lune, ou encore un astéroïde. Un honneur réservé à l'équipage d'Artemis 3, en 2025 au plus tôt.

Écoutez David St Jacques, astronaute de l'Agence spatiale canadienne, qui parle de la mission, au micro de Paul Arcand.

Ils ont donc jugé nécessaire de reporter le lancement. Il explique qu'une menace d'éclair est d'abord venue retarder le remplissage de carburant, et qu'un problème de fuite est ensuite survenu. Lorsque le problème s'est résolu, les ingénieurs ont été préoccupés par des difficultés de communication et des soucis associés au contrôle de la température.

La mission a pour but de propulser la capsule Orion sans équipage jusqu’en orbite autour de la Lune, pour vérifier que le véhicule est sûr pour de futurs astronautes, dont la première femme et la première personne de couleur qui marcheront sur la surface lunaire. Mais avant cela, se rendre sur la Lune est aussi stratégique, face aux ambitions de nations concurrentes, notamment la Chine. Mais le remplissage avait commencé avec environ une heure de retard à cause d’un risque de foudre trop élevé au milieu de la nuit. Vers 7 heures du matin heure locale, un nouveau problème, décisif, est apparu : l’un des quatre moteurs RS-25, sous l’étage principal de la fusée, n’arrivait pas à atteindre la température souhaitée, condition nécessaire pour pouvoir l’allumer. Le lancement était initialement prévu à 8 h 33 (14 h 33, heure de Paris) depuis l’aire de lancement 39B du centre spatial Kennedy, en Floride. Mais le problème devra d’abord être examiné en détail par les équipes de la NASA avant de déterminer une nouvelle date.
