| − | <p>Its called the Bond Rille, but like James Bond there is an attractive mystery to be explored. The crater G. Bond (not to be confused with W. Bond near the north pole) is the sharp-rimmed, shadow-filled 20 km wide crater at right center. To G. Bond’s west (left) is the long rille. The visibility of the rille varies greatly - it is sharp-edged in its southern and middle parts but shallows and softens to the north. Mike’s image shows something that the Lunar Orbitrer IV [http://www.lpi.usra.edu/resources/lunar_orbiter/images/img/iv_079_h1.jpg image] doesn’t: at its north end the Bond Rille makes a T junction with a faint rille that runs about 50 km roughly east-west. The eastern half is depicted on sheet 27 of the [http://www.lpi.usra.edu/resources/mapcatalog/LAC/lac27/ LAC chart], but the western end seems to be completely unknown. It also looks like the eastern end of the rille continues as a dimpled trough. Is that real? Near the southern end of the Bond Rille there is a hint (a subtle one) of a linear feature that spans the mare area between the craters G. Bond and Daniell. Could this be another older rille? Oh yes, this image also contains a prominent crater on the left…</p> | + | <p>I know the Moon quite well, as do many of the visitors to LPOD. So when [mailto:johnmcconnell9929@hotmail.com John McConnell] sent me this image I thought it was from the farside swirl group inside Mare Ingenii. But looking at the Clementine [http://pdsmaps.wr.usgs.gov/explorer-bin/mapmars4.cgi?WHEREFROM=PZ&VERSION=INTERMEDIATE&DATA_SET_NAME=moon_clementine_bw&PIXEL_TYPE=BIT8&SCALE=pixels/degree&PROJECTION=SINUSOIDAL&RESOLUTION=64&RESAMP_METHOD=NEAREST_NEIGHBOR&BANDS_SELECTED=%223,2,1%22&FORMAT=JPEG&LONBOX=16&LATBOX=16&GRIDLINE_FREQUENCY=none=AUTO&LAT=-35.5&LON=164.5&LINE=1024&SAMP=965 image] of the area failed to reveal a match to the pattern. According to the coordinates the Apollo 10 spacecraft was over 5°N, 115°E near the crater Firsof, which is much closer to the swirl in Mare Marginis. Hmm. Who can identify this area exactly? Post the coordinates of the swirl and most critically, a link to a confirming image, in the comment section below. Thanks! Oh yes, assuming this is a swirl, it has a very convoluted texture and hints at depth - especially at the top where a swirl on the flank of an impact crater is rimmed with darkness. </p> |
