If you tuned into the Artemis II mission livestream, you may recall hearing pure Moon Joy come from Dr. Kelsey Young as the crew described what they were observing when they flew by the Moon.

Hear from Dr. Young about that moment and more on #HWHAP >> https://t.co/KePx2W2Z50

🚀 "The European Service Module flew like a dream."
🌙 The @NASAArtemis II crew recently visited the European teams behind the spacecraft that powered their journey one million km through deep space, around the Moon and safely back to Earth.
👨‍🚀 Thanks for the kind words, @AstroVicGlover!

Vesta at its besta!

15 years ago on July 16, 2011, NASA's Dawn spacecraft entered orbit around Vesta, the second-largest body in the main asteroid belt! For more than a year, Dawn studied this unusual asteroid in depth before heading to its second destination, Ceres.

This is how we’re sending a flying robot to Saturn’s largest moon.

Today at 2pm ET: Go behind the scenes with the Dragonfly team for an exclusive cleanroom look at how this rotorcraft is coming together for its journey to Titan: https://t.co/Y7t31Srmfj

Keep your eye on Dragonfly 👀

We’re going live from the clean room where we’re building Dragonfly, the rotorcraft that will fly on Saturn’s moon, Titan. Join us on Twitch to learn more about the mission on July 16 at 2pm ET (1800 UTC): https://t.co/ytO98jAIOf

All aboard! 🚂
In June, eight of the 10 Artemis III SLS solid rocket booster segments traveled from Utah to @NASAKennedy.

The trip was led by Union Pacific’s new America 250 commemorative locomotive before a handoff to Norfolk Southern to continue east to Florida.
