We’re planning one of our biggest feats ever – bringing Mars samples to Earth – and you can play a part.
 
We're looking for your feedback on Mars Sample Return in a series of in-person meetings. Find details and updated meeting locations here: https://t.co/QCHBpGTELD https://t.co/nVt1Qi1tYn

There’s nothing like a weekend road trip – and you can follow @NASA_Orion’s journey as it heads back to Earth! We’ve listed all the ways you can keep up-to-date with the #Artemis I mission, including the live tracker, in this @Tumblr post: https://t.co/bZ8myWgPIw https://t.co/7B0LFI1RF3

Can we fix it? Yes, we can 

Astronauts Josh Cassada and Frank Rubio have successfully installed Roll-Out Solar Array on the starboard truss structure of the @Space_Station. They have also disconnected a cable allowing restoring a power channel to 75% of its operating capacity. https://t.co/zjBMzACmn0

Watch as the newly installed Roll-Out Solar Array deploys on the @Space_Station’s starboard truss structure for the first time. Astronauts Josh Cassada and Frank Rubio are more than five hours into their spacewalk. https://t.co/FcCoRJqeM7

It's a good day for some home improvement. Astronauts are currently ahead of schedule as they install new roll-out solar arrays outside the @Space_Station. What do you plan to work on today? 🛠️ https://t.co/kXOaA2KU3g

Spacewalk in progress. Watch astronauts @Astro_Josh (suit with red stripes) and Frank Rubio (unmarked suit) install new @Space_Station rollout solar arrays. The spacewalk is expected to last seven hours. https://t.co/FMKXeCAdkx

LIVE: @NASA_Astronauts prepare for a spacewalk at the @Space_Station to install new rollout solar arrays. https://t.co/33PxnbqDms

You must construct additional pylons. 🛠
 
Tune in Dec. 3 at 6am ET (1100 UTC) as @NASA_Astronauts Josh Cassada and Frank Rubio install a roll-out solar array to upgrade power generation on the @Space_Station's starboard structure: https://t.co/OfsrvEfJ3l https://t.co/qzur8GMLZK

As the @NASA_Orion spacecraft prepares for the journey back to Earth, we reflect on all the women who led the Artemis I mission to the Moon.

Through #Artemis, we will see the first woman and first person of color walk on the lunar surface. https://t.co/9wyQfJC8VG

LIVE NOW: The @NASA_Orion spacecraft is performing the first of two maneuvers to exit lunar orbit and begin its journey from the Moon back to Earth.

The burn is scheduled to begin at 4:53pm ET (21:53 UTC). #Artemis https://t.co/ymYGTm6IUK

Lots of Moon action this month—and we don’t just mean Orion’s journey! On the evening of Dec. 1, the Moon will appear very close to Jupiter. A few days later, it’ll cover up Mars and end the month by sliding past Saturn and Jupiter. Our What’s Up! guide has all the details. https://t.co/QN1T4xlHhB

Across NASA, we celebrated the Indigenous Native American culture and heritage that has been passed down from generation to generation for centuries. Check out our recap of #NativeAmericanHeritageMonth highlights from team members who take us higher. https://t.co/C1RP3BtDcL

"Being able to help other folks and increase knowledge of Native Americans within NASA — I've also learned a lot about my own background.”

LIVE NOW: We're previewing @NASA_Orion’s scheduled departure from its distant retrograde orbit around the Moon, which will begin on Thursday, Dec. 1 at 4:53pm ET (21:53 UTC). #Artemis https://t.co/sIFJhoQMHN

Today at NASA headquarters, our administrator, @SenBillNelson took @VP and @EmmanuelMacron on a virtual trip around the Moon with views from the #Artemis I mission. 

Now, it's your turn. Allons-y! https://t.co/eZx63LkrJ7

We go, and we go together.🤝

Today, @SenBillNelson hosted @VP & @EmmanuelMacron at our headquarters in Washington. From Earth's ocean to deep space, we continue to build on more than 60 years of collaboration for the betterment of all: https://t.co/4bWfI805WU https://t.co/UQa32bFHUo

The next generation of @NASAEarth science is moving forward.

Following an independent review, we’re implementing recommendations to ensure that our Earth System Observatory will meet all science goals to help us understand our changing planet: https://t.co/eSA2PRzlrS https://t.co/0s0Uiha08A

Is there water on the Moon? Yes, in the form of ice. Water is critical for future missions, which is why our golf cart-sized VIPER rover will explore the lunar South Pole in search of ice: https://t.co/ipfL0EqmlU https://t.co/vZL3f8Vz66

Regulators, mount up! 

Data from @ChandraXray and @SOFIAtelescope reveal a star cluster that regulates itself—allowing only a limited set of stars to grow before expelling most of the gas from the system. This process likely slows new star creation: https://t.co/T97kdYJlHk https://t.co/Xa5LyOPxdF
