NASA astronaut and Artemis II mission specialist Christina Koch peers out of one of the Orion spacecraft's main cabin windows, looking back at Earth, as the crew travels towards the Moon.

After the success of #Artemis II, what is the future of crewed space flight in the cislunar space? How can it complement robotic missions? Let us know what you think ⬇️

We'll be discussing this in sessions and panels at #COSPAR2026. Join us: cospar2026.org

Welcome back Artemis II crew!
Did you know the crew conducted health and science experiments throughout the entire mission?

Space research becomes Earth medicine.

#InternationalDayOfHumanSpaceFlight #ArtemisII

It’s #InternationalDayOfHumanSpaceflight, and 65 years to the day after Yuri Gagarin became the first human to escape the surly bonds of Earth, our Policy Manager @mrdegsy.bsky.social is at the Usher Hall in Edinburgh to hear from British astronaut Helen Sharman as part of #EdSciFest

One day we reached space, escaping our cradle for a new era of explorations and discoveries.
But what if space became a dumping ground for our fears, anxieties, and problems?
We’d only create another hell.
Find out in Neterun, face the Hell Galaxy!

And, as a bird, flee owre the wa’ o’ the world
To bigg his nest in the braid breast

Today is the #InternationalDayofHumanSpaceFlight, a day to celebrate the anniversary of the first human space flight in 1961 and affirm the role of science and technology in space travel🪐. Celebrate by learning about the first crewed lunar flyby in 50 years 🚀: https://ow.ly/bi3j50YGL2Y #astrophysics

On #InternationalDayOfHumanSpaceFlight, we mark how far exploration has come; from Gagarin’s first spaceflight to exciting missions like #ArtemisII.
Which makes us ask: what can support life?

Welcome back to Earth, Artemis II.

The mission marked a record-breaking orbit of the Moon, but it is also a reminder that as humanity's presence in space expands, so does the environmental impact.

An artist’s rendering of Yuri Gagarin, smiling under his white space helmet and wearing an orange spacesuit. In the background is the curve of the earth as seen from orbit with the Vostok spacecraft rising over his right shoulder.

Happy International Day of Human Space Flight to all who celebrate! It was April 12, 1961, on which Yuri Gagarin crewed the Vostok 1 mission, completing one orbit around Earth in just over 108 minutes. On that historic morning, Yuri called out “Poyekhali!” […]
