We are going.

For the first time, the @NASA_SLS rocket and @NASA_Orion fly together. #Artemis I begins a new chapter in human lunar exploration.

[ARCHIVED: NASA_SLS @NASA_SLS]

The liquid oxygen tank fill is complete, and the core stage is full! These tanks hold the propellant that will power the rocket's four RS-25 engines at #Artemis I liftoff.

[NASA @NASA]

LIVE NOW: Teams are preparing to launch the @NASA_Orion spacecraft to the Moon aboard the @NASA_SLS rocket. Watch coverage of the rocket fueling process for the #Artemis I mission.

[ATLAS Project @fallingstarIfA]

ATLAS observations of the DART spacecraft impact at Didymos!

[NASA @NASA]

IMPACT SUCCESS! Watch from #DARTMIssion’s DRACO Camera, as the vending machine-sized spacecraft successfully collides with asteroid Dimorphos, which is the size of a football stadium and poses no threat to Earth.

[NASA @NASA]

Eyes are locked on asteroid Dimorphos!

Only 20 minutes until impact, #DARTMission’s smart navigation is now precision-locked on non-hazardous asteroid Dimorphos, as the space craft travels at 6 kilometers per second.

Tonight, the world's first planetary defense test will take place, the Double Asteroid Redirection Test. At 7:14pm ET, DART’s impact will slow Dimorphos down, which will make it orbit Didymos faster. This technique could save Earth one day - the only preventable natural disaster.

[NASA @NASA]

Watch live from the POV of the spacecraft as our #DARTMission intentionally collides with a non-hazardous asteroid in the world’s first planetary defense mission.

DRACO camera feed starts at 5:30 pm ET (21:30 UTC): https://t.co/m295Y6uCot

[NASA @NASA]

🛰️ This is only a test – of planetary defense. Today, our #DARTMission is set to crash into a non-hazardous asteroid to test deflection technology, should we ever discover a threat.

Impact: 7:14pm ET (23:14 UTC). Watch our LIVE broadcast at 6pm ET: https://t.co/VAfF5ZXcYB

[ESA Webb Telescope @ESA_Webb]

1/ Thousands of never-before-seen young stars can be spotted here, caught up in the Tarantula Nebula’s web. This new image of the Tarantula Nebula, 30 Doradus, was captured by the #NIRCAM instrument on @ESA_Webb .

[ESA Webb Telescope @ESA_Webb]

Webb has taken its first image of an exoplanet!

This image shows the exoplanet HIP 65426 b in different bands of infrared light and demonstrates how #Webb’s powerful instruments can easily capture worlds beyond our solar system. Learn more here: https://t.co/evTXpH9gh0

[ARCHIVED: NASA's Exploration Ground Systems @NASAGroundSys]

#Artemis I Launch Director Charlie Blackwell-Thompson has given the 'go' to begin loading propellant into @NASA_SLS for #Artemis I.

Watch our mega Moon rocket @NASA_SLS get fueled up for launch. Follow @NASAGroundSys for updates on propellant loading in preparation for the #Artemis I liftoff from @NASAKennedy. https://t.co/u3mjNzC8Hu

[ARCHIVED: NASA's Exploration Ground Systems @NASAGroundSys]

T-5 hours and counting until the launch of Artemis I. We are in fast fill for liquid oxygen into the @NASA_SLS core stage, at 24% full. We are in slow fill for liquid hydrogen, at 4% filled.

Take Five: Captured in exquisite detail, @NASAWebb peered through the thick dust of Stephan’s Quintet, a galaxy cluster showing huge shockwaves and tidal tails. This is a front-row seat to galactic evolution: https://t.co/63zxpNDi4I #UnfoldTheUniverse

[NASA @NASA]

Cosmic cliffs & a sea of stars. @NASAWebb reveals baby stars in the Carina Nebula, where ultraviolet radiation and stellar winds shape colossal walls of dust and gas. https://t.co/63zxpNDi4I #UnfoldTheUniverse

[NASA @NASA]

We can't contain the excitement for @NASAWebb's first full-color images!

On Monday, July 11 at 5pm ET (21:00 UTC), President Biden will unveil one of the space telescope's first images of deep space as a preview of what's ahead: https://t.co/kP5JdQEpVz

[NASA @NASA]

🗓️ Mark your calendars for Tuesday, July 12 at 10:30am ET (14:30 UTC) as we release the first images from @NASAWebb.

Join an event, virtually or in your community, and celebrate with us as we #UnfoldTheUniverse: https://t.co/ix80dN3PHe
