In the concluding part of his analysis, Ken Murphy examines the potential growth of economic activity as humanity expands beyond Earth orbit to the Earth-Moon Lagrange points and eventually the lunar surface itself.

March 2012 marks the fortieth anniversary of the launch of one of the most extraordinary spacecraft ever constructed - Pioneer 10 - the first true deep space probe. The story of the Voyager spacecraft is well known but that of the Pioneer probes much less so.

Nearly 13.7 billion years ago, the universe was made of only hydrogen, helium and traces of lithium — byproducts of the Big Bang. Some 300 million years later, the very first stars emerged, creating additional chemical elements throughout the universe. Since then, giant stellar explosions, or supernovas, have given rise to carbon, oxygen, iron and the rest of the 94 naturally occurring elements ...

( Massachusetts Institute of Technology ) A team of researchers from institutions including MIT has detected the element tellurium for the first time in three ancient stars.

Researchers has detected the element tellurium for the first time in three ancient stars. Tellurium is rare on Earth.

Ancient stars suggest there was too little lithium in the early universe. Perhaps cold, light dark matter held back its production
