 NASA: Orbital Sunrise |

The Expedition 24 crew on the International Space Station photographed this image of polar mesospheric clouds illuminated by an orbital sunrise. Polar mesospheric, or noctilucent ("night shining"), clouds usually are seen at twilight, following the setting of the sun below the horizon and darkening of Earth's surface. Occasionally the station's orbital track becomes nearly parallel to Earth's day/night terminator for a time, allowing the clouds to be visible to the crew at times other than the usual twilight because of the station's altitude. This photograph shows polar mesospheric clouds illuminated by the rising, rather than setting, sun at center right. Low clouds on the horizon appear yellow and orange,... [Read More]

I finally managed to see this one, although it was a close-run thing. I was determined to get the maximum benefit from the much-praised 3D CGI by seeing it on the huge IMAX screen, and duly booked to go to the nearest one, a train journey away. On the morning I was due to go, a heavy overnight snowfall had added to the chaos of almost three weeks of freezing weather and snow, causing major transport disruption with doom-laden warnings for those foolish enough to poke their noses outside their homes. I nearly didn’t bother to make the attempt, but in the end I slogged the half-mile through the snow to the station, to find that not only did my train turn up (and arrive at its destination) on time, but the one home did as well. Just occasionally, everything goes right!
