Same video as before of ATLAS observing the DART impact, but tracked sidereally (with the stars). Each frame is about 40 seconds, and the entire sequence is about two hours.

Here are the first images taken by #LICIACube of #DARTmission impact on asteroid #Dimorphos. Now weeks and months of hard work are now starting for scientists and technicians involved in this mission, so stay tuned because we will have a lot to tell!

🛰️ 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

👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: nasa.gov/webbfirstimages/

Get ready for a pre-dawn planet party for all of June! Venus, Mars, Jupiter, and Saturn will all make an appearance before sunrise with Mercury and the Moon joining in later in the month. Here's what's up in the night sky in June: planetary.org/night-sky/nigh…

My fellow imager and friend Chris Go captured this excellent image earlier today of a rare triple transit event on Jupiter. All four Galilean moons can be seen here. From left - Europa, shadow, Ganymede, shadow, Callisto and Io in partial eclipse at far right.

.@BepiColombo is feeling the heat as it swoops past the Venus dayside 🌡️😅 Sunlight reflected from Venus is heating the spacecraft by up to 50 degrees! And the reaction wheels used to keep Bepi pointing straight are feeling the pull of the planet’s mighty gravity💪🌕 #VenusFlyby

One month ago, our LightSail 2 spacecraft took this image of northern Australia, including the Gulf of Carpentaria. What are some of your favorite things about Australia?

Tonight, observers from the western US to east Asia will see the Moon enter the deepest part of Earth’s shadow – a total lunar eclipse. Wherever you are, it’s the perfect time to get familiar with this cosmic shadow show: go.nasa.gov/3flcaRY

“Mind-bottling, isn't it?” The blades of glory, aka rotor blades of the #MarsHelicopter, have been unlocked and are ready for testing. Next, we’ll do a slow-speed spin-up of the blades for the first time on the Martian surface. go.nasa.gov/ingenuity

Two bots, one selfie. Greetings from Jezero Crater, where I’ve taken my first selfie of the mission. I’m also watching the #MarsHelicopter Ingenuity as it gets ready for its first flight in a few days. Daring mighty things indeed. Images: go.nasa.gov/2RaUBKF

Scan this image for the various pieces of my landing system, which did their jobs perfectly before coming to rest on Mars. Teams of experts poured years of work into each one. My safe landing is what tells you they nailed it. go.nasa.gov/2NsKVK0 📷: @HiRISE #CountdownToMars

The Planetary Society has advocated for a Mars microphone for over 25 years. Today, @NASA released the first recorded sounds of Mars. Congratulations @NASAPersevere and Planetary Society members on this remarkable achievement!
