Just one more image of the amazing #auroraborealis of last 19 January. Taken from my city garden. The bright spot in the centre is planet Jupiter. The view is towards southeast, with the aurora high in my southern sky at 52 degrees north! @daveatcogs.bsky.social @elisabethkosters.bsky.social

🌄 Good morning! The Osinov Pass is the last major hurdle before travelers coming from Oskemen reach the Altai Mountains of #Kazakhstan. The view from the pass summit is particularly impressive at sunrise. Have a wonderful Sunday. 🤗

This behemoth machine is carrying the Artemis 2 Moon rocket out to the launch pad. It carried the Shuttles I launched in too. A massive, clanking crawler and skilled crew, taking infinite care.
