Giordano Bruno Crater   Leave a comment

gbcrater

Giordano Bruno Crater, 22km across.  Recently the LROC team produced a very high resolution image and published a 778meg TIFF file.  I took the 1 meg thumbnail of that file and combined it with the elevation data cut from LDEM_128.jp2 produced by the LOLA science team.   Here are a couple of snapshots of the result with the camera just off the floor of the crater.

A little to the left of the previous image, both looking North.

Snapshot of 11-million-face .ply file generated from LDEM_85S_20M.jp2 produced by the LOLA science team.  Click for full size.  Colorized by height and by lighting, which brings out the mountains and high plateau.  Shackleton Crater at center-right.  Where would you land?

Peary Crater at the North Pole   Leave a comment

Peary_Crater

Peary Crater with the North Pole of the Moon in the distance.   At the left the sharp-edged crater is Hermite A, a virtual twin of Shackleton Crater at the South Pole.  The color is lighter with height.  Most of the deeper craters in this view are candidates for ice mining.  From LDEM_85N, produced by the LOLA science team, imaged in Mathematica and visualized in Meshlab.

Boussingault Crater in the lower right quadrant of the Moon.  The crater-in-a-crater aspect holds out hope the floor will be composed of material from the interior.  See http://www.lpod.org/?m=20060410

Imaged from ldem_64 produced by the LOLA science team.  64 pixels per degree, 10 x 20 degree section colored and lit in Meshlab.

Shackleton Crater, Illuminated   Leave a comment

shackleton_60

Shackleton Crater with the sun 30 degrees above the horizon, illuminating the floor of the crater.  From LDEM_875S_10M.JP2 produced by the LOLA science team; reduced to 100 meters per pixel.

10 km square view of floor of Shackleton Crater at 10 meter resolution.  Spires are sensor artifacts when a mirror-like surface overwhelms the sensor.  Glare ice?  Sunlike illumination is at 20 degrees elevation.

shackfloor5

6km square image of Shackleton Crater floor at 5 meter resolution.   Sunlike illumination at 15 degrees above horizon.  Opposite field of view from above.  I still like the top of the mound as a landing site and base.

Camera down in the crater.

Hagen J   Leave a comment

Image

Meshlab view of Hagen J (47km) rear center.  Location on the far side of the Moon, Latitude 47.5-50S and Longitude 135-140.  About a quarter of the rim of Hagen is visible to the right.  Image derived from LDEM_512_90S_45S_090_180.jp2 produced by the LOLA science team. 512 pixels per degree makes each pixel about 60 meters.  There are stripes of lower-res areas that fill gaps in the data.  The bumps in the seams between strips also appear as a scintillation in the texture.

Image

A close-up of Hagen J produced in Blender, a 3D animation program.  Looking South, the illumination is from the East.  Click images for full size.

Giant Planisphere   Leave a comment

Firefly Planisphere Deluxe by Storm Dunlop and Wil Tirion at 15″ in diameter had print too small to read without magnification.  Here is a 36″ version.  The star chart is to sixth magnitude from the back of the original.
