Richard C Hoagland says public understanding of major achievements of the Space Age over the past 30 years -- carried out by both the former Soviet Union and the United States -- increasingly seems to have been nothing more than a carefully constructed "version" of a much more extraordinary truth. Even Apollo 11 astronaut Neil Armstrong, in a recent White House ceremony, hinted at the existence of such information, when he cryptically ended his prepared remarks by saying, "...we have only completed a beginning; we leave you much that is undone... there are... breakthroughs available to those who can remove one of truths protective layers. There are places to go beyond belief..." Space imaging data, made available to the Mars Mission (13-year independent space research group) investigation of these possibilities, from a variety of official sources (including increasing "inside leaks"), now strongly suggests the presence (on at least two worlds -- Mars and the Moon) of extensive ancient artificial structures in the solar system. The most celebrated of these potential "ancient artificial structures" is known to millions as the "Face on Mars" -- a mile long, 1500-foot high Martian landform that eerily resembles a humanoid face, lying in a Martian desert called "Cydonia"... where no "face" belongs. Nearby, lie equally provocative structures which resemble vast, formerly enclosed, ancient and now crumbling "high tech pyramids"... possible former "environmental arcologies" left by someone who tried to make Mars "home"... long before our fleeting, recent visits. Far more disturbing than this evidence (if it is indeed disturbing, to a generation raised on "Star Trek"...) is other, equally-documented evidence of a profound, deliberately politically-motivated cover-up of this important data by both major spacefaring nations... for more than 30 years.
