Humans Envisioned On Mars In 25 Years
"The Global Exploration Roadmap, unveiled by the International Space
Exploration Coordination Group on Sept. 22, offers two 25-year human pathways to Mars. One follows the “Asteroid next” approach favored by U.S. President Barack Obama, while the other features a “Moon next” gateway more akin to the George W. Bush administration’s scrapped Constellation program." See: http://www.aviationweek.com/aw/gener...&channel=space |

About time...I'd rather see Moon first than this Administration's vague promises of an Asteroid by 2025...when they don't even have a target destination selected yet! |

As to why they would have to go to either the Moon or an asteroid from a base at one of the L points that would have to be shielded against solar storms rather than one in LEO is a good question. But this is all about making big exotic future plans that you can't afford, not rationality. Pat |

But this is all about making big exotic future plans that you can't afford, not rationality. Pat What can be afforded? What can be made to pay? Weather satellites for sure. Spy satellites are likely. Navigation satellites for sure. Telecom sats for sure. And even these likely could be trimmed down with more ground based technologies and long duration high altitude vehicles in the atmosphere. Some I suppose some will propose a multinational approach and history will dispose of the multinational approach, IMO. What would it take to have a Mars colony? A product to ship back? An imperative to survive for someone other? The ability to self sustain the colony for example to make it own space suits or robotic avatars to work at the surface? A space based star wars shield to project against the fragments of creation that hit Mars? It surely would take an easier way up to orbit, a faster trip out to the red planet, a more massive ship than anyone currently dreams to have real shielding, nuclear power, fusion power, ......................... am I rational or simply rationing reason..........Trig |

There was a reason for that in the original plan. Part of the President's FY2011 proposal was for a robotic precursors program, which included a NEO survey satellite to be placed in the Venus band of the solar system to catch asteroids we can't see that well from Earth's vantage point when looking toward the sun. This would have enlarged the target set of asteroid destinations, and an asteroid would have been selected out of this enlarged data set. Hence the delay in selection. |

EML1 and 2 are better for cryogenic propellant depots than LEO. In terms of the delta V, EML1 and 2 are much closer to the moon as well as the NEOs than LEO. |
