🗓️ Mark your calendars for Tuesday, July 12 at 10:30am ET (14:30 UTC) as we release the first images from NASA Webb Telescope. Join an event, virtually or in your community, and celebrate with us as we #UnfoldTheUniverse: go.nasa.gov/3R0LQxp

We can't contain the excitement for NASA Webb Telescope'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: go.nasa.gov/3NUQ8Dx

Take Five: Captured in exquisite detail, NASA Webb Telescope 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: nasa.gov/webbfirstimages #UnfoldTheUniverse

Cosmic cliffs & a sea of stars. NASA Webb Telescope reveals baby stars in the Carina Nebula, where ultraviolet radiation and stellar winds shape colossal walls of dust and gas. nasa.gov/webbfirstimages #UnfoldTheUniverse

Watch our mega Moon rocket ARCHIVED: NASA_SLS get fueled up for launch. Follow ARCHIVED: NASA's Exploration Ground Systems for updates on propellant loading in preparation for the #Artemis I liftoff from NASA's Kennedy Space Center. youtu.be/JncMoFTn9xc

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

Apollo-type PHA 161989 Cacus. Diameter 1000-2250m. First observed at La Silla 8th of Feb' 1978. Close approach 1st of Oct', distance 8.6 million km. #SpotTheAsteroid #IAWN #QHY42Pro QHYCCD Royal Astronomical Society

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: esawebb.org/images/HIP-654…

#Artemis I Launch Director Charlie Blackwell-Thompson has given the 'go' to begin loading propellant into ARCHIVED: NASA_SLS for #Artemis I. MORE: go.nasa.gov/3TFkJcw

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 Telescope . Read more: esawebb.org/news/weic2212/

🛰️ 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: youtu.be/4RA8Tfa6Sck

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): youtu.be/-6Z1E0mW2ag

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.

Watch NASA’s #DART Spacecraft Approach to Asteroid Dimorphos !! #DartMission youtu.be/-6Z1E0mW2ag

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.

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.

ATLAS observations of the DART spacecraft impact at Didymos!

LIVE NOW: Teams are preparing to launch the Orion Spacecraft spacecraft to the Moon aboard the ARCHIVED: NASA_SLS rocket. Watch coverage of the rocket fueling process for the #Artemis I mission. Follow ARCHIVED: NASA's Exploration Ground Systems for updates. x.com/i/broadcasts/1…

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.

We are going. For the first time, the NASA_SLS rocket and Orion Spacecraft fly together. #Artemis I begins a new chapter in human lunar exploration.
