"This image depicts a Boeing worker installing an F-1 engine on the Saturn V S-IC flight stage at the Michoud Assembly Facility (MAF). The Saturn IB and Saturn V first stages were manufactured at the MAF, located 24 kilometers (approximately 15 miles) east of downtown New Orleans, Louisiana. The prime contractors, Chrysler and Boeing, jointly occupied the MAF. The basic manufacturing building boasted 43 acres under one roof. By 1964, NASA added a separate engineering and office building, vertical assembly building, and test stage building."

The SLS (Space Launch System) Core Stage by Numbers

Technicians with NASA and SLS core stage lead contractor Boeing, along with RS-25 engines lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, are nearing a major milestone for the Artemis II mission. The SLS (Space Launch System) rocket’s core stage for Artemis II is fully assembled and will soon be shipped via barge from NASA’s Michoud Assembly Facility in New Orleans to the agency’s Kennedy Space Center in Florida. Once there, it will be prepped for stacking and launch activities.

Get to know the core stage – by the numbers.

Standing 212 feet tall and measuring 27.6 feet in diameter, the SLS core stage is the largest rocket stage NASA has ever built. Due to its size, the hardware must be shipped aboard NASA’s Pegasus barge.

900 miles

Once loaded, the barge – which was updated to accommodate the giant core stage -- will travel 900 miles to Florida across inland and ocean waterways. Once at Kennedy, teams with our Exploration Ground Systems team will complete checkouts for the core stage prior to stacking preparations.

18 Miles + 500 Sensors

As impressive as the core stage is on the outside, it’s also incredible on the inside. The “brains” of the rocket consist of three flight computers and special avionics systems that tell the rocket what to do. This is linked to 18 miles of cabling and more than 500 sensors and systems to help feed fuel and steer the four RS-25 engines.

8.8 million

Speaking of engines… Our SLS Moon rocket generates approximately 8.8 million pounds of thrust at launch. Two million pounds come from the four powerful RS-25 engines at the base of the core stage, while each of the two solid rocket boosters produces a maximum thrust of 3.6 million pounds. Together, the engines and boosters will help launch a crew of four Artemis astronauts inside NASA’s Orion spacecraft beyond Earth orbit to venture around the Moon.

733,000 Gallons

Achieving the powerful thrust required at launch calls for a large amount of fuel - 733,000 gallons, to be precise. The stage has two huge propellant tanks that hold the super-cooled liquid hydrogen and liquid oxygen that make the rocket “go.” A new liquid hydrogen storage sphere has recently been built at Kennedy, which can store 1.25 million gallons of liquid hydrogen.

Four

The number four doesn’t just apply to the RS-25 engines. It’s also the number of astronauts who will fly inside our Orion spacecraft atop our SLS rocket for the first crewed Artemis mission. When NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover along with CSA astronaut Jeremy Hansen launch, they will be the first astronauts returning to the Moon in more than 50 years.

Artemis III core stage receives thermal protection coating

NASA completed another step to ready its SLS (Space Launch System) rocket for the Artemis III mission as crews at the agency's Michoud Assembly Facility in New Orleans recently applied a thermal protection system to the core stage's liquid hydrogen tank.

Building on the crewed Artemis II flight test, Artemis III will add new capabilities with the human landing system and advanced spacesuits to send the first astronauts to explore the lunar South Pole region and prepare humanity to go to Mars. Thermal protection systems are a cornerstone of successful spaceflight endeavors, safeguarding human life, and enabling the launch and controlled return of spacecraft.

The tank is the largest piece of SLS flight hardware insulated at Michoud. The hardware requires thermal protection due to the extreme temperatures during launch and ascent to space—and to keep the liquid hydrogen at minus 423 degrees Fahrenheit on the pad prior to launch.

"The thermal protection system protects the SLS rocket from the heat of launch while also keeping the thousands of gallons of liquid propellant within the core stage's tanks cold enough. Without the protection, the propellant would boil off too rapidly to replenish before launch," said Jay Bourgeois, thermal protection system, test, and integration lead at NASA Michoud. "Thermal protection systems are crucial in protecting all the structural components of SLS during launch and flight."

In February, Michoud crews with NASA and Boeing, the SLS core stage prime contractor, completed the thermal protection system on the external structure of the rocket's liquid hydrogen propellant fuel tank, using a robotic tool in what is now the largest single application in spaceflight history.

The robotically controlled operation coated the tank with spray-on foam insulation, distributing 107 feet of the foam to the tank in 102 minutes. When the foam is applied to the core stage, it gives the rocket a canary yellow color. The Sun's ultraviolet rays naturally "tan" the thermal protection, giving the SLS core stage its signature orange color, like the space shuttle external tank.

While it might sound like a task similar to applying paint to a house or spraying insulation in an attic, it is a much more complex process. The flexible polyurethane foam had to withstand harsh conditions for application and testing. Additionally, there was a new challenge: spraying the stage horizontally, something never done previously during large foam applications on space shuttle external tanks at Michoud. All large components of space shuttle tanks were in a vertical position when sprayed with automated processes.

Overall, the rocket's core stage is 212 feet with a diameter of 27.6 feet, the same diameter as the space shuttle's external tank. The liquid hydrogen and liquid oxygen tanks feed four RS-25 engines for approximately 500 seconds before SLS reaches low Earth orbit and the core stage separates from the upper stage and NASA's Orion spacecraft.

"Even though it only takes 102 minutes to apply the spray, a lot of careful preparation and planning is put into this process before the actual application of the foam," said Boeing's Brian Jeansonne, the integrated product team senior leader for the thermal protection system at NASA Michoud.

"There are better process controls in place than we've ever had before, and there are specialized production technicians who must have certifications to operate the system. It's quite an accomplishment and a lot of pride in knowing that we've completed this step of the build process."

The core stage of SLS is the largest NASA has ever built by length and volume, and it was manufactured at Michoud using state-of-the-art manufacturing equipment. Michoud is a unique, advanced manufacturing facility where the agency has built spacecraft components for decades, including the space shuttle's external tanks and Saturn V rockets for the Apollo program.

Mademoiselle Perceval

Texte écrit par Pauline LAROCHE-VACHAUD

Dans l'ouvrage Il était une fois Trept, on trouve quelques phrases, presque anodines, traversées par ce nom tout droit sorti d'un monde de chevaliers. Puis l'on passe… Page suivante, chapitre suivant... A moins d'entendre parler celle ou celui qui l'a côtoyée. Alors on est saisi. Par la modernité, la pugnacité, le courage, l'obstination, le romanesque, même, de cette jeune femme, inconnue parmi les Justes – et pourtant... Une jeune institutrice, tout juste 25 ans, dans une petite école de campagne, aux prises avec les tourmentes de l'Histoire. Une femme en corsaire, ongles des pieds et des mains peints. Comprendre : en ce temps-là, en ce lieu-là, diablement pas comme tout le monde, déterminée, libre. Une femme qui n’a guère parlé, semble-t-il, de ses activités pendant la guerre. Or, cette humble maîtresse d’école était en lien avec des Russes devenus Salagnards d'adoption : un officier du Tsar – Michel Roubtzoff –, qui, catapulté en France suite à la Révolution de 1918, avait pris sous son aile Paul et Léon Lositsky. Ces derniers étaient les enfants de l’officier Franzevitch Lositsky, s'avéraient lointains parents, par leur mère - une Pavlona - du Tsar lui-même, et se retrouvaient exilés en France pour les mêmes raisons. Au gré d’autres tourmentes de l’Histoire, et par l’entremise d’un certain Michoud, directeur de banque parisienne, ils avaient atterri dans un Château du Nord-Isère, à Salagnon. Or, Mademoiselle Suzanne Perceval était proche de ces « Russes blancs » qui, pour aristocrates fortunés et pour militaire tsariste qu’ils étaient, avaient néanmoins choisi le chemin de la Résistance. Comme elle, sans doute. Avec elle, sans doute. Elle qui annoncera à ses élèves, très émue, la mort d’un de ces hommes lors des combats de la Libération de Bourgoin, en août 1944…

Une question se pose sérieusement, bien sûr : ces lignes peuvent-elles être une trahison de son silence ? Nous n’irons pas fouiner. Notre seul désir : écouter les souvenirs vibrants qu’elle a laissés chez celles et ceux qui sont encore présents pour en parler, et faire vivre, autant que possible, son humanité à toute épreuve.
