    Only image ever taken of a transit of a space shuttle (Atlantis) and the Hubble Space Telescope (HST) in front of the Sun, during the last repair mission of Hubble, obtained from Florida at 100 km south of the Kennedy Space Center on May 13th 2009 12:17 local time, several minutes before grapple of Hubble by Atlantis.

    Transit duration: 0.8s. Transit bandwidth on Earth: 5.6 km. Altitude: 600 km. Speed: 7 km/s (25000 km/h). Length of Atlantis : 35m, length of Hubble : 13m.
    Transit forecast (place, time...) calculated by www.calsky.com.

    Takahashi TOA-130 refractor (diameter 130mm, final focal 2200mm), Baader solar prism and Canon 5D mark II. Exposure of 1/8000s at 100 ISO, extracted from a series of 16 images (4 images/s) started 2s before the predicted time.

    The following transit has been taken from the vicinity of the Kennedy Space Center on May 12th, only 24 hours after the launch of Atlantis as it was halfway to Hubble, at a distance of only 260 km. Duration of the transit: only 0.3 second. The thin silhouette confirms that the cargo bay doors were opened.
