Was the Moon Originally Cold?

Abstract

In recent reports (I ) the term racemization is used inappropriately.It is stated in both reports that Lisoleucine racemizes to D-alloisoleucine. This reaction is epimerization, not racemization. Racemization of L-iSOleucine results in the formation of DLisoleucine. As stated in Eliel (2): "'racemization is the process of producing a racemic modification starting with one of the pure enantiomers."

Engineering Potential for Lunar Missions After Apollo

“…The scientific requirements include imaging and sampling of lunar surface materials, elemental and mineralogical measurements, and geophysical measurements such as thermal, seismic, and gravity profiles, with the object of deter mining the source, pre-accretion history, mode of accumulation, and post-accretion history of the lunar material. In addition to their intrinsic interest, these ancient events demand understanding for the broader view: by developing a bulk composi tional model and a compatible thermal history for the Moon, we may elucidate the early history of the Earth-Moon system (cf., for example, [10]- [13]) and thence learn more about the conditions required for the origin of life.…”
