Extrait :
Steven H Silver alerts us to the fact that, earlier this month, the International Astronomical Union approved the naming of a crater on Mars for Isaac Asimov.
This NASA side-by-side image shows: "Asimov Crater is located in Noachis Terra at 47.0°S, 355.1°W; Danielson is in western Arabia Terra at 8.0°N, 7.0°W. Both craters were named by the IAU this year. Note that Asimov is largely filled with material; large pits mark the interface between the ancient crater walls and the material that filled the crater. Although not obvious at the scale of the images presented here, the darkest materials in Danielson Crater are windblown sand dunes. The Asimov picture is from Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red wide angle camera image M01-01232; the Danielson picture is also from the MOC red wide angle camera, image M01-00847. These pictures were taken during the MOC Geodesy Campaign ten years ago in May 1999. The images were map-projected by personnel at Malin Space Science Systems."
