<A HREF="http://www-sn.jsc.nasa.gov/curator/seh/ldef/ldef_db.htm">database</A> is maintained at the 
<A HREF="http://www.jsc.nasa.gov/">Johnson Space Center (JSC), Houston, 
Texas</A>, and consists 
of five data tables containing information about individual features, digitized images of selected 
features, and <A HREF="http://setas-www.larc.nasa.gov/setas/ldef.html">LDEF</A> 
hardware (i.e., ~950 samples) 
<A HREF="http://www-sn.jsc.nasa.gov/curator/seh/seh.htm">archived</A> at 
<A HREF="http://www.jsc.nasa.gov/">JSC</A>.  About 4,000 penetrations (>300 
micrometers in diameter) and craters (>500 micrometers in diameter) were identified and photo-documented during the 
disassembly of <A HREF="http://setas-www.larc.nasa.gov/setas/ldef.html">LDEF</A> at the 
<A HREF="http://www.ksc.nasa.gov/ksc.html">Kennedy Space Center (KSC)</A> [1], while an 
additional 4,500 or so have 
subsequently been characterized at 
<A HREF="http://www.jsc.nasa.gov/">JSC</A>.  The 
<A 
HREF="http://www-sn.jsc.nasa.gov/curator/seh/ldef/ldef_db.htm">database</A> also contains some data which has been 
submitted by various PIs, yet the amount of such data is extremely 
limited in it's extent, and 
investigators are encouraged to submit any and all M&D-type data to JSC for inclusion within the 
<A HREF="http://www-sn.jsc.nasa.gov/curator/seh/ldef/ldef_db.htm">M&D 
database</A>.
