I took this photo of sunset on orbit during Expedition-30 to the ISS using a fisheye lens. It takes 7 ½ seconds for the disk of the sun to slip below the horizon. It goes from bright daytime lighting to dark night lighting in about twice this time. There is no extended twilight on orbit. On Earth, it takes 2 minutes for the solar disk to set where our atmosphere, acting as a light buffer, gives extended twilight.

More astrophotography can be found on my Instagram and Twitter accounts.

Very cool, love to have actual crew members posting their photos here. I’ve always wanted to sit in the cupola and watch the sun or watch a vehicle arrive.

This is incredible! Thank you for posting this, it must be so cool to see sights like these. Unrelated, but how long are you guys usually up there for?
