To everyone on Earth, Merry Christmas from our @NASA_Astronauts aboard the International

BREAKING 🚨: For the first, James Webb Space Telescope has detected a galaxy similar in weight to the Milky Way

Happy anniversary, Servicing Mission 1! 🥳 The pivotal first astronaut servicing mission to Hubble launched #OTD in 1993. Its dedicated crew upgraded the telescope and made critical repairs that fixed Hubble's blurry beginnings. Read more: https://go.nasa.gov/3OAdFN6

It looks like there is some good news with Voyager 1 – communications have been restored, allowing the spacecraft to keep sending data back. The fact that Voyager 1 is 47 years old and still functioning and providing information to us is a testament to the quality of the research and engineering that went into its development by @NASA a half-Century ago. Voyager 1 is 15.4 billion miles from Earth – still venturing into deep space, on its own, carrying out its mission. An astounding accomplishment! https://space.com/space-exploration/missions/voyager-1-interstellar-spacecraft-finds-its-voice-again-as-nasa-restores-communications

#Thanksgiving is over, but #BlackHoleFriday is back for seconds! For our annual celebration of these space oddities, and get pulled in by fun facts and the latest discoveries revealing the cosmic mysteries of black holes.

"We have much to be thankful for." From the Space_Station , our crew share their #Thanksgiving greetings—and show off the menu for their holiday meal.

Two years ago, Artemis I soared into the heavens—setting the stage for humanity's return to the surface of the Moon. This was just the beginning. And through #Artemis, we have leap after giant leap in store.

So are we ready for a Starliner replacement?

The clearest picture that was ever taken of the surface of Venus...

This is Mars !

🤯 Feast your eyes on @chandraxray ’s view of NGC 6872, a colossal spiral galaxy in the Pavo (Peacock) constellation! At a mind-blowing 522,000 light-years across, this galaxy is over five times larger than our very own Milky Way. Talk about a cosmic giant! https://go.nasa.gov/4cfaWlo

Just in: @NASAPersevere observed a rock with distinct features that may indicate that Mars hosted microbial life in its ancient past, but further research is needed. It contains a compelling detection of organic material, chemical signatures, and evidence of water interaction. https://go.nasa.gov/3WDv6kH

NASA's New Horizons spacecraft flying over mountains on Pluto 🏔️

We're with you when you fly! ✈️ From developing the world’s first all-electric airplane to improving air traffic control, we’re making aviation safer & more sustainable. We're working to expand air transportation, shorten taxi times on the runway, & reduce carbon emissions.

Along with international partners, we're using the same generically shaped wing design to create research models that will help us better understand how air moves around an aircraft during takeoff+landing. More on this innovation for the benefit of all: https://go.nasa.gov/3XzVHzL

Juneteenth commemorates the day enslaved African Americans in Galveston, Texas learned of their freedom. This view from the Space_Station shows the city and Galveston Bay: https://go.nasa.gov/4bY0Nu9

We’re back, baby! Our Voyager 1 spacecraft is conducting normal science operations for the first time since November 2023. All four instruments – which study plasma waves, magnetic fields, and particles – are returning usable science data. https://go.nasa.gov/3RofgY7

“We’re building a blueprint for exploring the solar system.” Take a deep dive into the #Artemis missions to the Moon with NASA’s chief exploration scientist Jacob Bleacher on the most recent episode of our Small Steps, Giant Leaps podcast. https://go.nasa.gov/4elS4DB

Lightning-fast? No, it's laser-fast! We sent hundreds of pet pictures and videos to (and from) the @Space_Station to test out our @NASALaserComm technology: https://go.nasa.gov/3KCiqUh

We’ve selected 10 proposals to study more affordable, faster ways of bringing samples from Mars’ surface back to Earth. These samples could help us understand how habitable worlds like Earth form and evolve. https://go.nasa.gov/4aVs6UH

What footprint will we leave on Earth? Human activity is a key driver of land degradation, putting the health of people & the planet at risk. Join #GenerationRestoration & take action for a liveable planet in the future. More on #WorldEnvironmentDay: https://worldenvironmentday.global/?twclid=2331n20ax7viumrcpirb9ahie5

We're now targeting 10:52am ET (1452 UTC) on June 5 for the launch of our @BoeingSpace #Starliner Crew Flight Test. The @ULALaunch teams have addressed the issue that resulted in the scrub of the June 1 launch attempt. Get more details: http://go.nasa.gov/453AP5X

This week at NASA, we launched two small satellites that will observe Earth’s climate, discovered a planet 40 light-years away, and peered into the dark universe. Don’t miss a minute of what we’re up to: http://nasa.gov/subscribe

The world’s most powerful space telescope has done it again. Webb has discovered what appears to be a new record-holder for the most distant known galaxy — shattering its own previous record. This galaxy existed only 290 million years after the big bang: https://blogs.nasa.gov/webb/2024/05/30/nasas-james-webb-space-telescope-finds-most-distant-known-galaxy/

Gateway is a vital part of NASAArtemis . Built with industry and international partners, the next-gen space station will support: 🌕 A sustained presence around the Moon. 👩‍🚀 Crewed missions to the lunar surface. 🔬 Deep space science and discovery. https://go.nasa.gov/3yAU5eO

Blue Origin is rolling out the New Glenn simulator again today for a series of transport erector integrated ground tests in preparation for launch later this year. Tests will include powering up the pumps that provide pressure to the vehicle hydraulic system, validating the ground system supplying commodities to the rocket, and a rapid retract test of the umbilical connections. More to come. 🚀

May's full moon is springing into our sky till Friday, May 24. Known as the flower moon, corn moon, or milk moon, discover what this month's full moon means for cultures around the world: https://go.nasa.gov/44TpqFI

Mission managers from NASA, BoeingSpace and ULALaunch continue to evaluate a path forward toward launching #Starliner 's Crew Flight Test. The teams are now working toward a launch opportunity at 12:25pm ET on Saturday, June 1, with additional opportunities on Sunday, June 2, Wednesday, June 5, and Thursday, June 6. Get more details: https://go.nasa.gov/4ayy9y4

"Puffy planets" like WASP-107 b, an exoplanet 200 light-years from Earth, are helping unravel an interstellar mystery—thanks to data from our orbiting @NASAWebb telescope: https://go.nasa.gov/4dRIPem

As the Apollo 11 vehicle was rolling to the launch pad in Florida #OTD in 1969, in the California desert NASA test pilot Bill Dana was flying the wingless HL-10 lifting body, showing that a future spacecraft could glide to Earth like an airplane.

Reaching the stars starts with our workforce! For the 12th year in a row, we've been ranked by @PublicService as the best place to work in the federal government among large agencies. Thank you to everyone who contributed in making NASA the #FedBPTW: https://go.nasa.gov/3V3AVaa

Access to food is a human right. As hostilities continue in Gaza, people are struggling to meet their most basic needs, including food & shelter. Humanitarian organizations must have unhindered access to people in need wherever they are.

We will be discussing our PREFIRE mission, which aims to improve life on Earth and provide information on climate change by studying heat loss from Earth’s polar regions. Listen in at 3pm ET on May 15: http://go.nasa.gov/4dCWOV6
