And a critical milestone for an Earth-observing satellite …
A few of the stories to tell you about – This Week at NASA!
Le prochain test de répétition de pré-lancement de la mission lunaire Artemis I.
La NASA vise le 18 juin pour le début de la prochaine répétition générale avec notre fusée Space Launch System et le vaisseau spatial Orion au Kennedy Space Center en Floride.
Cette répétition est le dernier test nécessaire avant le lancement de la mission Artemis I autour de la Lune.
Le test comprend un compte à rebours d’environ deux jours, au cours duquel les équipes de lancement s’entraîneront aux opérations, au calendrier et aux procédures qu’elles suivront lors du lancement réel.

Le télescope spatial Hubble détecte la signature spectrale des débris vaporisés qui révèle une combinaison de matériaux rocheux-métalliques et glacés, les ingrédients des planètes. Ces résultats aident à décrire la nature violente des systèmes planétaires évolués et la composition de leurs corps en désintégration. Crédit : NASA, ESA, Joseph Olmsted (STScI)
Nouvelles de la NASA à la réunion de l’American Astronomical Society (en anglais)
Les nouvelles concernant les missions de la NASA lors de la 240e réunion de l’American Astronomical Society comprenaient des astronomes utilisant les données de notre Hubble Space Telescope and other NASA observatories to see, for the first time, a dead star called a white dwarf consuming both rocky-metallic and icy material, the ingredients of planets.
This instance of cosmic cannibalism can help astronomers learn more about the makeup of newly forming systems.
Also discussed, the potential of NASA’s Nancy Grace Roman Space Telescope. The telescope’s unprecedented field of view will make it possible to study stellar streams in a large number of galaxies for the first time.
Astronomers can use these observations to better understand how galaxies grow and the nature of dark matter.

NASA Completes Critical Testing for Earth Observing Satellite
The Joint Polar Satellite System-2 satellite, or JPSS-2 that NASA is building for the National Oceanic and Atmospheric Administration (NOAA) recently completed its thermal vacuum testing.
The critical test is meant to show that the spacecraft and its instruments can perform successfully in the harsh environment of space.
JPSS-2 is targeted for launch on November 1st from Vandenberg Space Force Base in California.
The satellite will provide data to help improve our understanding of extreme weather and climate change.

NASA Showcases Inflatable Heat Shield Before Spaceflight Demo
NASA’s Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID will ride to space on the JPSS-2 launch as a secondary payload.
LOFTID is a demonstration of a hypersonic inflatable aeroshell that could one day help land humans on Mars.
Our Langley Research Center in Hampton, Virginia, recently hosted an event for the media to learn more about the technology.
Following its launch to low-Earth orbit, LOFTID will inflate and descend back to Earth to demonstrate how it can slow down a spacecraft and help it survive the trip down through a planet’s atmosphere.

2022 Astronaut Hall of Fame Induction Ceremony
Congratulations to former NASA astronauts Dave Leestma, Sandy Magnus, and Chris Ferguson. They are the newest inductees to the U.S. Astronaut Hall of Fame.
They were inducted as the Hall of Fame’s class of 2022 during a June 11th ceremony at the Kennedy Space Center Visitor Complex.
That’s what’s up this week @NASA …
