EROS-PIA02907_modest.jpgA strange drawing made by lights and shadows...64 visiteEros' irregular shape creates interesting and beautiful scenes where the Sun shines obliquely on the surface. In the absence of an atmosphere, and hence no secondary illumination reflecting from atmospheric molecules, shade appears nearly as black as space. This image, taken from the NEAR Shoemaker spacecraft on May 2, 2000, from an orbital altitude of 50 kilometers (31 miles), shows one of the more telling and yet comical combinations of light and shadow. The entire scene is about 1.8 kilometers (1.1 miles) across. High spots near the edges of shadows, like the 35-meter (115-foot) diameter boulder just below the center of the frame, seem almost to "float" above the surface. With a little imagination, the shadow dominating the right side of the frame could be seen as a small, long-eared terrier bending over to sniff his dinner!

How does it feel,
To be on your own,
With no directions home,
Like a complete unknown,
Like a rolling stone..."

Titan-Huygens_Landing_Site-11-PIA07229_modest.jpgHuygens' descent map (3) 64 visiteThe octagons indicate anticipated fields of view of panoramic mosaics of images taken by Huygens' descent imager and spectral radiometer instrument as the probe reaches certain altitudes during its descent. This map shows the footprints for mosaics to be assembled from 36 individual images at each altitude, with the field of view cut off at 75° from straight down although the actual images will extend all the way to the hazy horizon. Each mosaic made this way will be about 1.300 by 1.300 pixels. The largest octagon (in red) is about 1.120 Km across and represents the field of view for the mosaic of images taken at an altitude of 150 Km. From that height, individual pixels in the center of the image will be about 150 mts across, though haze between the ground and the camera at that height will likely degrade the resolution in those images. The location of the anticipated landing site is based on modeling of Titan's winds, and the actual landing site will be different if the actual winds experienced by Huygens during descent differ from this model.

Comets-Wild_2-01.jpgApproaching Wild 2 (2)64 visiteCaption NASA originale:"On January 2, 2004 NASA's Stardust spacecraft made a close flyby of comet Wild 2.
Among the equipment the spacecraft carried on board was a navigation camera.
This is the 34th of the 72 images taken by Stardust's navigation camera during close encounter. The exposure time was just 10 milliseconds".

23-Farside-Luna3.jpgThe Moon from "Luna 3"64 visiteCaption NASA originale:"The Luna 3 spacecraft returned the first views ever of the far side of the Moon. The first image was taken at 03:30 UT on 7 October 1959 at a distance of 63.500 Km after Luna 3 had passed the Moon and looked back at the sunlit far side. The last image was taken 40 minutes later from 66.700 Km. A total of 29 photographs were taken, covering 70% of the far side. The photographs were very noisy and of low resolution, but many features could be recognized. This close up view taken with the narrow angle camera shows the far side has fewer maria (the dark areas) than the near side. The image is centered at 20° N, 95° E and the dark area to the left and just below center is Mare Marginus and below that Mare Smythii, just at the boundary between the near and far sides. The left half of the image shows the near side of the Moon, including the circular Mare Crisium at far left (Luna 3-26)".

37-Ranger7.jpgMare Nubium: the impact of Ranger 764 visiteCaption NASA originale:"The final two images taken by Ranger 7 before its impact on the Moon's Surface. These image were taken by the number 1 and 3 P-channel cameras at 0.39 and 0.19 seconds before impact from an altitude of 1070 and 519 meters, respectively. The pictures are cut off because the spacecraft impacted the surface before completing the transmission. The top image was taken by the P3 camera and the bottom image by P1. The P3 image is about 25 m across. North is at 12:30 for both images. The impact occurred on 31 July 1964 at 13:25:48.82 UT (Ranger 7, CP1002)".

41-Ranger8.jpgMare Tranquillitatis64 visiteCaption NASA originale:"Ranger 8 camera B image of the Moon about 5 seconds before impact. Ranger 8 impact took place on 20 February 1965 at 9:57:37 UT. This picture was taken from a distance of 11 Km. The area is in the Sea of Tranquillity about 2° north of the Apollo 11 landing site. The frame is about 2 Km across and North is up. Features as small as 4 meters across can be seen (Ranger 8, B090)".
