During a lengthy news conference on Friday, NASA provided a detailed overview of how it plans to return astronauts to the lunar surface as soon as 2028 as part of its Artemis Program.
Although much of the information behind these plans has been previously reported at Ars Technica and elsewhere, this marked the first time NASA has laid them out in detail and acknowledged some substantial changes in the architecture.
Most notably, for SpaceX's Starship vehicle, the revised plan calls for the Orion spacecraft to dock with the Starship lunar lander in high-Earth orbit before transiting to the Moon. And for Blue Origin, the mission architecture includes four launches of the New Glenn rocket, but no spacecraft-to-spacecraft refuelings. Additionally, the Blue Origin plans allows for the possibility of its Blue Moon lander rendezvousing with Orion in low-Lunar orbit.
NASA does not have, nor want, nuclear weapons. But when it comes to a particular metric that is part of the Artemis Program to land people on the Moon, NASA guards a particular number like it is trying to prevent outsiders from cracking nuclear codes.
I am speaking of the number of Starship launches required to fuel a Starship-based lunar lander in low-Earth orbit such that it can fly out to the Moon, land there, and return to lunar orbit.
This number has been a moving target over the years. The general response from NASA has typically been, 'We don't know for sure, so we're not going to say.' In 2023, for example, the then-director of NASA's Human Landing System, Lisa Watson-Morgan, told Ars, "We have a general idea, but I’m reluctant to say exactly what that is."
La NASA a présenté début octobre 2026, au Congrès international d'astronautique, le calendrier détaillé que SpaceX doit suivre pour poser des astronautes sur la Lune avec Starship. Il prévoit un atterrissage lunaire sans équipage fin 2027, quelques mois avant la première mission habitée.
Dans l'actualité scientifique de la semaine du 12 octobre 2026 : le bouclier thermique d'Artémis II à peine abimé, le premier (et dernier) vol de la fusée réutilisable du Japon, et l'ambition de SpaceX qui vise une récupération complète du Starship. C'est le récap’ !
Welcome to Edition 9.15 of the Rocket Report! The launch I'm most looking forward to in the next few weeks is that of Japan's Martian Moons Exploration (MMX) mission. MMX is one of the marquee space science missions launching this year, and it's set to leave Earth as soon as Monday (US time) aboard a Japanese H3 rocket. The spacecraft will visit Phobos and Deimos, the two asteroid-like moons of Mars, deploying a rover and collecting specimens for return to Earth in 2031. Exploration at its finest.

Reflect Orbital looks to India for launch capacity. California-based Reflect Orbital, the startup attempting to offer sunlight on-demand with in-space mirrors, announced the purchase of two launches Wednesday from Indian launcher Skyroot Aerospace, Payload Space reports. One of the launches will use Skyroot's Vikram-1 rocket, which became the first privately developed Indian rocket to reach orbit in July. The other will fly on an upgraded rocket called the Vikram-1U.
Elon Musk espère un quinzième vol du Starship dans quatre à six semaines. SpaceX tenterait alors, pour la première fois, de rattraper les deux étages de la fusée avec la tour de lancement. Le vol précédent, le 28 septembre, avait été le premier à atteindre l'orbite.
Le Forte, un cargo semi-submersible qui transporte l'étage supérieur du 13e vol de Starship, est entré dans le golfe du Mexique, dernière étape avant le Texas, où il est attendu ce mercredi 7 octobre. Il a quitté l'île Christmas, dans l'océan Indien, le 28 août, puis a contourné l'Afrique par le sud.
SpaceX a lancé ses trois modèles de fusées en moins de quatre jours. Le Starship est parti ce lundi 28 septembre, puis deux Falcon 9 et une Falcon Heavy ont décollé en moins de 13 heures, entre ce jeudi 1er octobre et la nuit suivante. Pour la première fois, le Starship a atteint l'orbite.
Welcome to Edition 9.13 of the Rocket Report!
This week, SpaceX celebrated the first orbital launch of its new Starship rocket. I'm not sure many people, at least those outside of SpaceX, expected it to take 14 flights of Starship before it technically reached low-Earth orbit, but Monday morning's launch finally added that to SpaceX's list of accomplishments with its new super-heavy rocket. Starship had gone 99 percent of the way to orbit before, only held back by safety concerns around the possibility of stranding the huge rocket in space.
What was most notable for SpaceX with this Starship flight was that it unlocked a massive growth potential for Starlink, with the first 26 of the network's new-generation Starlink V3 satellites successfully deployed Monday.
SpaceX a publié ce mardi 29 septembre de nouvelles vidéos au ralenti du décollage du Starship, filmées depuis le pas de tir et la tour de Starbase, au Texas. Elles montrent le 14e vol de la fusée géante, le premier à atteindre l'orbite.
SpaceX a diffusé en direct, ce lundi 28 septembre, le 14e vol d'essai du Starship, qui était aussi le premier vol orbital de la fusée. Mais à quoi ressemble le décollage du lanceur, quand on se trouve à moins d'une dizaine de kilomètres ? Une vidéo permet de faire cette expérience sonore et visuelle.
SpaceX a placé 26 satellites Starlink V3 en orbite ce lundi 28 septembre 2026, lors du 14e vol de son Starship. Ils pèsent environ 52 tonnes au total. Une infographie publiée sur X classe ce chargement au troisième rang des plus lourds de l'histoire, derrière la navette soviétique Bourane et la station américaine Skylab.
SpaceX's Starship rocket thundered into the sky over South Texas early Monday. It was the 14th test flight of the world's most powerful launch vehicle. This time, however, the rocket's massive upper stage squeezed out some extra oomph from its Raptor engines and accelerated to orbital velocity.
On all of Starship's previous flights, SpaceX intentionally dialed back the full capability of the rocket to fly a suborbital trajectory, slow enough for Earth's gravity to pull the vehicle back into the atmosphere before it could complete a full lap around the planet. After several successful suborbital flights in a row, SpaceX officials decided this launch should go all the way to low-Earth orbit. And it did.
What's more, SpaceX packed 26 of the company's newest generation of Starlink broadband satellites into the rocket's cargo bay. One by one, the flat-packed satellites—too large to fit inside SpaceX's workhorse Falcon 9 rocket—were released from Starship's payload deployer using a system of pulleys and cables to eject the satellites overboard like a Pez dispenser spits out candy.
SpaceX faisait voler pour la 14e fois sa fusée Starship ce lundi 28 septembre 2026. Le vol orbital a été écourté (3 heures, au lieu de 10). De superbes clichés du décollage ont néanmoins été partagés.
Le 14e vol d'essai du Starship, la fusée géante de SpaceX, est attendu à partir du 28 septembre 2026 depuis le Texas. Cette fois, l'entreprise vise pour de bon l'orbite, avec de vrais satellites Starlink à bord.
Sur le papier, tout est censé bien se dérouler. La fusée géante Starship doit réussir son tout premier vol orbital ce lundi 28 septembre. Mais il y a aussi la possibilité d'un loupé. Voilà ce que SpaceX dit avoir prévu.
SpaceX a diffusé ce lundi 28 septembre une animation qui détaille, étape par étape, le premier vol orbital de son Starship. Le vaisseau doit rester près de dix heures dans l'espace, alors que les treize vols d'essai précédents duraient au mieux une heure environ.
Le Starship de SpaceX a décollé du Texas ce lundi 28 septembre 2026 pour son 14e vol d'essai, et son propulseur Super Heavy a réussi son retour en mer dans le golfe du Mexique. Pour la première fois, l'étage supérieur de la fusée géante vise ensuite une vraie orbite autour de la Terre.

Pending regulatory approval, SpaceX said today it intends to launch its 14th Starship mission as early as September 22. This flight is notable, as it will be the first time that SpaceX attempts to launch the experimental vehicle into orbit.
The company set a target liftoff time of 7:15 am local in Texas (12:15 UTC), with a 75-minute launch window. Sunrise in Brownsville, Texas, is 7:17 am CT, so the launch could make for some striking imagery.
The super heavy lift rocket will be carrying 26 of the larger V3 Starlink satellites into an orbit 275 km above the Earth. In an update on its website, SpaceX said the Starship upper stage will seek to complete six orbits around the Earth before completing its mission after about 10 hours.
Le 14e vol d'essai du Starship, la fusée géante de SpaceX, est attendu autour du 15 septembre 2026 depuis le Texas. Cette fois, l'entreprise vise pour de bon l'orbite, avec de vrais satellites Starlink à bord.
SpaceX diffuse de nouvelles images du Ship 40, la fusée géante repêchée dans l’océan Indien. Pour la première fois, on y voit ses ingénieurs prélever des morceaux du bouclier thermique en pleine mer.
Un mois après son amerrissage dans l'océan Indien, l'étage supérieur du Starship de SpaceX a été hissé hors de l'eau et arrimé sur un navire géant. Direction le Texas, pour une inspection que l'entreprise n'avait jamais espéré pouvoir mener.
SpaceX made Florida's Space Coast home to the world's busiest spaceport for a decade, but that will change this year. The company is significantly cutting the number of launches from Florida until Starship arrives, a senior SpaceX official confirmed Tuesday.
The Falcon 9 rocket has been SpaceX's workhorse, routinely launching batches of satellites for the company's Starlink network, primarily from launch pads at Cape Canaveral Space Force Station and NASA's Kennedy Space Center in Florida. There were 165 Falcon 9 launches last year—about three flights per week—and about 75 percent of them carried Starlink satellites.
This year is different. SpaceX has launched more missions from its West Coast launch pad at Vandenberg Space Force Base in California since January, and this trend will amplify for the rest of the year.
Louisiana Gov. Jeff Landry said Tuesday that SpaceX will commit $100 billion to develop Starship factories and launch pads in the state's coastal areas. In doing so, the company seeks to replicate the Starbase facility it has built over the last decade in southern Texas on a larger scale.
The announcement capped months of speculation about SpaceX's interest in a sprawling parcel of land along the Gulf coast of Louisiana, which offers room to build multiple launch towers and offers access to the methane propellant that fuels the Starship rocket.
Gwynne Shotwell, the president and chief operating officer of SpaceX, said the "Starbase Louisiana" facility would become a self-sustaining spaceport with propellant production, power generation, deep-water shipping capabilities, vehicle processing facilities, and an airport on site.
Un seul moteur allumé, mais un grand pas pour le prochain vol. SpaceX vient de tester la manœuvre de désorbitation de son Starship, un ultime coup de frein cosmique indispensable pour ramener le vaisseau sur Terre en un seul morceau.
Welcome to Edition 9.07 of the Rocket Report! China's workhorse Long March rocket family appears to be rebounding quickly from a rare launch failure August 10. Chinese officials have not publicly released any information on what may have caused the Long March 7A rocket to break apart less than 90 seconds after liftoff, but the rocket's use of YF-100 engines initially raised questions about the failure's impact on other Chinese rockets that use the same type of engines. But no biggie. YF-100 engines returned to flight six days later with the successful flight of a Long March 12 rocket, and the heavy-lift Long March 5—also with YF-100 engines—is set to launch in a few days with one of China's most important space missions of the decade: the Chang'e 7 lunar lander en route to the Moon's south pole.

Trouble in Taiwan. A prototype for a future satellite launch vehicle developed by Taiwan's top weapons manufacturer veered off course shortly after liftoff Wednesday, Taiwan's Central News Agency reports. The "trajectory anomaly" prompted the activation of the rocket's self-destruct mechanism. The government agency responsible for the test flight, the National Chung-Shan Institute of Science and Technology (NCSIST), reported no injuries or property damage. Debris from the rocket fell into a planned safety control zone near the southern tip of Taiwan.
Un tweet sibyllin d'Elon Musk jette le flou sur le calendrier de SpaceX. Alors qu'une capture inédite de l'étage supérieur par la tour Mechazilla était pressentie dès le prochain essai, la communauté s'interroge.
SpaceX est sorti d'un silence long de plusieurs jours pour donner à son tour des nouvelles de l'étage supérieur de sa fusée Starship. Une prise de parole qui survient juste après la diffusion de clichés d'un photographe qui se trouvait dans les parages.
SpaceX's most recent Starship test flight may have ended July 24, but its mission isn't over yet.
The spacecraft splashed down in the Indian Ocean intact after flying halfway around the world from SpaceX's launch base in South Texas. Engineers expected the ship's life to end with a fiery disintegration after toppling over, just as past Starships have done following splashdown.
Numerous onboard sensors and cameras, along with buoys and drones in position at the splashdown zone, have provided important data for SpaceX to assess the performance of the ship's heat shield after each test flight, so officials accepted the post-flight conflagrations. That day, Starship tipped over and remained intact, surprising just about everyone.
Alors qu'on craignait de la voir sombrer dans l’océan Indien, la fusée géante de SpaceX flotte toujours. Des clichés pris par un photographe sur l'île Christmas révèlent que le Ship 40 a été remorqué avec succès vers ce territoire australien.
SpaceX a partagé de saisissants clichés et une vidéo au crépuscule du Ship 40 dérivant dans l’océan Indien. Mais alors que les équipes déploient des trésors d'ingéniosité pour le sécuriser, la météo menaçante rend le remorquage de la fusée de plus en plus incertain.
Alors qu'il décrivait le bouclier thermique comme l'obstacle ultime en mai dernier, Elon Musk estime désormais le problème résolu après le treizième vol d'essai du Starship. SpaceX franchirait ainsi l'étape la plus critique vers la réutilisabilité totale de sa fusée géante.
SpaceX and the state of Louisiana are close to finalizing a deal for the launch company to acquire about 130,000 acres along the northern coast of the Gulf of Mexico.
There have been persistent rumors about such an agreement for months, but now The Times-Picayune | The New Orleans Advocate reports that Louisiana Gov. Jeff Landry is expected to announce the agreement later this month.
The deal would give SpaceX control of an 18-mile stretch of marshland southwest of Lafayette. The site, known as Pecan Island, became available as part of a legal settlement that resolves dozens of lawsuits that blame ExxonMobil for pollution and coastal land loss, the newspaper reports.
L'actualité de la semaine du 27 juillet 2026 a été tristement marquée par les incendies en Gironde et dans Les Landes, dont les conséquences dévastatrices ont été observées depuis le ciel. SpaceX a aussi entamé le sauvetage du Starship, qui flottait au large de l'Australie après le 13e vol d'essai.
À la dérive depuis plus de six jours dans l’océan Indien, le Ship 40 de SpaceX s’apprête enfin à être remorqué. Une flottille de navires spécialisés fait route vers le géant d'acier pour entamer une opération de récupération inédite.
Welcome to Edition 9.05 of the Rocket Report! It was a big week for launch contracts, with both Rocket Lab and SpaceX scoring sizable deals from the US military for their respective Electron and Falcon 9 rockets. The vehicles have been the workhorses for small and medium lift for the United States over the past decade and may remain so for some time. Also, there will be no Rocket Report next week, as I am traveling on assignment, and Stephen is taking a week off.

Rocket Lab wins large Electron deal. Rocket Lab Corporation announced this week that it has been awarded its largest launch contract to date, a $266 million multi-launch contract with the US Space Force. Under the contract awarded by the US Space Force Space Systems Command, Rocket Lab will execute 12 suborbital launches, with up to six additional launches. The first launch of this contract is expected no earlier than the end of 2026.
Tombé intact dans l'océan Indien lors de son 13ᵉ vol d'essai, l'étage supérieur du Starship refuse de couler. Mais pourquoi SpaceX a-t-elle attendu près de quatre jours avant d'envoyer un navire de repêchage ?
Non, ce ne sont pas des visuels extraits d'un jeu vidéo ou d'un blockbuster. Les nouvelles photos irréelles du Starship publiées par SpaceX sont bien réelles — et la physique derrière ce spectacle est tout simplement saisissante.
SpaceX successfully launched its Starship vehicle on Friday and appeared to demonstrate important and credible steps toward fulfilling the massive rocket's immense promise. As soon as the vehicle's next flight, Starship could go orbital, begin delivering satellites into space, and potentially return to the launch site to be 'caught' by the tower.
All of this is impressive engineering on a gigantic scale. But despite the marked progress with the 13th test flight of Starship, one key issue—probably the key issue when it comes to Starship's future—remains unresolved.
This concerns Starship's heat shield, the roughly 18,000 ceramic tiles that protect the vehicle's underbelly during its fiery return through Earth's atmosphere. And some experts say SpaceX's current approach may not get Starship to its ultimate goal of flying frequently, at low cost.
