The decade-old Google Lunar X-Prize (GLXP) will officially end on March 31st, 2018 very likely without a winner due to multiple teams dropping out of the race from financial/technical issues or facing launch vehicle delays. Extracting lessons to be learned would be useful in order to create more successful prizes in the future. http://acuriousguy.blogspot.ca/2018/01/glxp-bites-dust-before-reaching-finish.html
