La NASA continue de préparer le lancement de la fusée Artemis I Moon

Le ciel bleu et les nuages ​​blancs servent de toile de fond au système de lancement spatial Artemis I (SLS) et au vaisseau spatial Orion au-dessus de la rampe de lancement mobile de la rampe de lancement 39B au Kennedy Space Center de la NASA en Floride le 30 juin 2022. Le SLS et Orion sont déplacés à la plaquette du transporteur à chenilles 2. Un test préalable est appelé un test humide. Artemis I sera le premier test intégré des engins spatiaux SLS et Orion. Lors de missions ultérieures, la NASA fera atterrir la première femme et les premières personnes de couleur sur la Lune, ouvrant la voie à une présence à long terme sur la Lune et servant de tremplin sur le chemin vers Mars.

Depuis le système de lancement spatial ([{ » attribute= » »>SLS) and Orion returned to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on July 2, workers have extended the access platforms surrounding the rocket and spacecraft to perform repairs and undertake final procedures before returning to launch pad 39B for the launch of the Artemis I mission.

Technicians are hard at work inspecting, testing, and fixing equipment associated with a seal on the quick disconnect of the tail service mast umbilical that was identified as the source of a hydrogen leak during the wet dress rehearsal test that ended on June 20. Engineers have disconnected the umbilical and are currently in the process of inspecting the area where they will replace two seals on the quick disconnect hardware. Working in tandem with those repairs, engineers also executed the last remaining engineering test that is part of the integrated testing operations in the VAB.

In addition, teams performed other planned work on aspects of the rocket and spacecraft. Engineers swapped out a computer on the Interim Cryogenic Propulsion Stage called the Inertial Navigation and Control Assembly unit that was used during wet dress rehearsal activities with the one that will be used for flight. They will test the unit next week. The just installed flight unit includes newly calibrated inertial navigation sensors and updated software to guide and navigate the upper stage during flight.

Several batteries for the rocket elements, including for the solid rocket boosters and the ICPS have been activated by technicians. The batteries on the core stage will be activated in the coming weeks, and all the batteries will then be installed. The batteries provide power for the rocket elements during the final portion of the countdown on launch day and through the ascent.

Engineers also charged the batteries for the secondary payloads located on the Orion stage adapter and will work to install payloads inside the Orion spacecraft in the coming weeks.
