Several hundred scientists, including all 142 US and international principal investigators for the Apollo 11 samples, gathered in downtown Houston\u2019s Albert Thomas Exhibit and Convention Center for the Apollo 11 Lunar Science Conference between Jan. 5 and 8, 1970. During the conference, the scientists discussed the chemistry, mineralogy, and petrology of the lunar samples, the search for carbon compounds and any evidence of organic material, the results of dating of the samples, and the results returned by instruments left on the Moon as part of the <a href=\"https:\/\/www.nasa.gov\/history\/50-years-ago-one-small-step-one-giant-leap\/\">Early Apollo Surface Experiments Package (EASEP)<\/a>.

Although the scientists had been studying the samples for only about three months, they reported several initial findings to the conference. Opening the conference, a panel of leading scientists in the field of lunar and planetary geology, chemistry, and astrophysics, reviewed the state of knowledge about the Moon and leading theories about its origins. The panel included<\/p>\n\n\n\n<ul>\n<li>Gene Simmons, Chief Scientist at the NASA Manned Spacecraft Center, now the Johnson Space Center in Houston,<\/li>\n\n\n\n<li>Harold C. Urey, physical chemist at the University of California, San Diego,<\/li>\n\n\n\n<li>John A. O\u2019Keefe, astronomer at NASA Goddard Space Flight Center,<\/li>\n\n\n\n<li>Thomas Gold, astrophysicist at Cornell University,<\/li>\n\n\n\n<li>Eugene M. Shoemaker, geologist with the US Geological Survey, and<\/li>\n\n\n\n<li>Edward Anders, chemist at the University of Chicago.<\/li>\n<\/ul>\n\n\n\n<p>For the next four days, scientists exchanged a flood of information from the preliminary results of their investigations of the first set of lunar samples. Because of the large volume of information and the preliminary nature of the results, the assembled scientists could not reach any major conclusions. Some intriguing findings included the finding of more than 20 minerals also found on Earth, possibly indicating a common origin for both bodies, but also three minerals not found on Earth; the rock samples dating to between 3 and 4 billion years while the soil samples contained particles dating to 4.6 billion years; most of the rocks appeared to have formed locally while a small percentage appeared to have come from distant lunar highlands, likely ejected during meteorite impacts; and that some lunar material had undergone \u201cgardening\u201d, that is dug up from below the surface and then reburied. The scientists found no evidence of any living organisms, past or present, in any of the lunar samples studied.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"apollo_lunar_science_conference_jan_5_to_8_1970\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/01\/apollo_lunar_science_conference_jan_5_to_8_1970_s70-20424.jpg\" width=\"309\" height=\"215\"> <img decoding=\"async\" loading=\"lazy\" alt=\"apollo_lunar_science_conference_jan_5_to_8_1970\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/01\/apollo_lunar_science_conference_jan_5_to_8_1970_s70-20883.jpg\" width=\"302\" height=\"215\"><br>\n<em>Left: Opening panel at the conference, (left to right) Simmons, Urey, O\u2019Keefe, Gold,<br>\nShoemaker, and Anders.

Given the short amount of time the investigators had to examine their samples, and the fact that all the samples came from just a single site on the Moon, the Sea of Tranquility, they found it difficult to make concrete conclusions. Gene Simmons, newly appointed chief scientist at MSC, perhaps best summed up the state of lunar science at the end of the conference, \u201cThere is a large amount of undigested data and very little interpretation,\u201d he said. \u201cYou\u2019ll see in the next six months many revisions of statements as to what it all means.\u201d By the time of the conference, <a href=\"https:\/\/www.nasa.gov\/history\/50-years-ago-apollo-12-return-to-houston\/\">Apollo 12 astronauts<\/a> Charles \u201cPete\u201d Conrad, Richard F. Gordon, and Alan L. Bean had returned an additional 76 pounds of lunar samples from a second site on the Moon in the Ocean of Storms. Results from the analysis of those samples as well as the additional samples returned by later Apollo missions added greatly to our understanding of the Moon\u2019s origins, while at the same time raising new questions requiring further lunar exploration to answer.<\/p>\n\n\n\n<p>The prestigious journal <em>Science<\/em> dedicated its Jan. 30, 1970, edition to the papers presented at the conference. The editors of the unique edition dubbed \u201cThe Moon Issue\u201d worked with the papers\u2019 authors during the conference to ensure timely publication of the articles. The sheer number of papers resulted in an issue more than twice as thick as a regular edition but one that documented the scientific results of a great accomplishment.<\/p>\n\n\n\n<p>The Lunar Science Conference evolved into an annual event, for the first three years meeting in January and then every March thereafter. In 1978, the organizers renamed it the Lunar and Planetary Science Conference to reflect the broadened scope of topics discussed at the annual meeting. The annual conference continues to attract scientists from around the world to review and discuss the latest scientific developments in lunar and planetary exploration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Less than five months after Apollo 11 astronauts Neil A.
