What Do We Have to Conquer Before Colonizing Mars?

This learning path has been created for you.
Playlist Description

Before we can colonize on Mars, what hurdles must we first conquer? One day, life on Earth will be no more. Our population may overtake this planet’s natural resources, creating unsustainable levels of competition for fuels, sustenance and space. Like the dinosaurs, we might be the victims of a cataclysmic asteroid strike, the effects of global warming, or a new ice age. If not, the sun will eventually burn out, making life on this planet completely untenable.

But what will we do when life on Earth is no longer an option? It may sound like science fiction, but we might just up and move to Mars. It’s not too farfetched an idea—we have successfully sent a number of unmanned missions to Mars, including Pathfinder, Viking, and most recently the aptly named Mars Curiosity rover. There are a number of hurdles we face before we could set up a permanent colony on the red planet. Here are some of them.

Complete video at: http://fora.tv/2010/10/16/Long_Conversation_with_Ken_Foster_and_Pete_Worden Pete Worden, Director of NASA's Ames Research Center, predicts there will be permanent settlements on Mars within the next half-century. "We are on the verge of extending humanity into the solar system, into the cosmos," he says. ----- Long Conversation, an epic relay of one-to-one conversations among some of the Bay Area's most interesting minds, took place over six hours in San Francisco on Saturday, October 16, 02010. Interpreting the Long Conversation in real time was a data visualization performance by Sosolimited; an art and technology studio out of M.I.T. Long Conversation was presented with a live performance of 1,000 minutes of composer Jem Finer's Longplayer. Simon P. ("Pete") Worden, Ph.D. (Brig. Gen., USAF, Ret.) is Director of NASA's Ames Research Center (ARC) at Moffett Field, Calif. Before joining NASA, he held several positions in the United States Air Force and was research professor of astronomy at the University of Arizona, Tucson. He is a recognized expert on space issues -- both civil and military. Dr. Worden has authored or co-authored more than 150 scientific papers in astrophysics, space sciences, and strategic studies. He served as a scientific co-investigator for two NASA space science missions, and received the NASA Outstanding Leadership Medal for the 1994 Clementine mission. He has been named the 2009 Federal Laboratory Consortium Laboratory Director of the Year. Kenneth J. Foster is the Executive Director of Yerba Buena Center for the Arts in San Francisco. Foster has more than 20 years of experience as an arts administrator, curator, educator, and performing arts presenter. In addition, he has served as a board member for such prominent arts organizations as the Association of Performing Arts Presenters, Dance USA, and Chamber Music America, among others.
