Meet the crew of Artemis II. These four astronauts will spend nearly 10 days in deep space, helping prepare for future lunar missions and beyond.

🇺🇸 Reid Wiseman: Commander
🇺🇸 Victor Glover: Pilot

Even though the Moon is constantly orbiting Earth, we always see the same side. This happens because the Moon’s rotation period matches its orbit around our planet - a phenomenon called tidal locking. The side we never see from Earth is called the far side of the Moon 🌕

[RASC National @rasc]

The Artemis II mission is the first crewed flight around the Moon in more than 50 years 🌕🚀
Astronauts will travel beyond Earth orbit aboard the Orion spacecraft, flying around the Moon and back to Earth while testing critical systems in real deep-space conditions.

It’s World Honey Bee Day! 🐝✨ Honey bees nest in cavities where the only light comes from the hive entrance. Too much artificial light at night can keep that entrance lit 24/7, disrupting their natural day/night cycle. Let’s keep our skies (and nights) dark for the bees.
