Space exploration volunteers wanted (The catch? It’s a one-way ticket) The Guardian
The next generation of astronauts may hurtle through the cosmos for years or decades on a mission to explore distant planets and stars â€“ and never return.
A senior Nasa official has told the Guardian that the world’s space agencies, or the commercial firms that may eventually succeed them, could issue one-way tickets to space, with the travellers accepting that they would not come back.
Return to the Moon: Unless it’s profitable, it won’t be permanent Ronald Bailey Reason Magazine
The Apollo moon landings have often been compared to the explorations of Christopher Columbus and the Lewis and Clark expedition to Oregon. For example, on the 20th anniversary of the first moon landing, President George H.W. Bush declared, “From the voyages of Columbus to the Oregon Trail to the journey to the Moon itself: history proves that we have never lost by pressing the limits of our frontiers.”
But what boosters of the moon expeditions overlook is that the motive for pressing the limits of our frontiers in those cases was chiefly profit….
Earth’s Dwindling Resources Drive Space Exploration by Marsha Freeman Space.com
In the early 1970s, [Krafft Ehricke] developed the concept of the extraterrestrial imperative to make clear that for mankind to continue to grow, we have no choice but space exploration. The “closed world” of the Earth is finite and eventually, resources will run out, he concluded. But developing and exploiting extraterrestrial resources would remove any “limits to growth,” a pessimistic concept that became popular in the 1970s. There are no “natural” limits, Ehricke insisted, only those that mankind places on himself.
The Space Review has three essays this week looking at whether past is prologue as humanity slowly and clumsily moves out into the cosmos. The essays invoke Abraham Lincoln, Charles Darwin and Daniel Boone.
Nader Elhefnawy has an interesting essay over at The Space Review today about how space advocates who see space as a safety valve for overpopulation may be getting it wrong. It’s an interesting argument that is well worth a read.
