Pods to the Asteroids
Have we discussed the plan championed by Landau and Strange? I'm catching
up with my print reading, and when I saw their article in the Dec 2011 Scientific American, I thought it was strange that I didn't recognize it as an SSP topic. Their plan involves a capsule ride to a deep-space ion-drive ship, used in a kind of powered-shuttler scheme, and to support EV tasks with pods. Test flight would be to an orbit above the lunar south pole to control a fleet of robotic explorers. "Focusing on an easier mission could stunt exploration by setting a dead end for technological capability. Conversely, striving for a harder mission could perpetually delay any meaningful exploration by setting targets too far out of reach. Our desgin baseline falls between these extremes. It is a one-year round-trip that launches in 2034, with 30 days spent exploring asteroid 2008 EV5." (pg 62) What's the reaction of SSP to the 3 principles they use: flexibility, not having to newly invent everything, and to design a program that can maintain forward momentum even if one component runs into problems or delays. /dps |

Landau-Strange baseline design
Any comments? Anybody have links to other documents of this plan?

But robotic lunar exploration is just as easily accomplished from Earth as it is from an "ion-drive ship". And likely for a whole lot less $$$ and for a lot longer period of time. Dave |

The idea of doing the lunar trip is to do a shakedown cruise near enough to earth for safety, and the robot control is just a serving of gravy on top of the rest of the mission objectives. The trip to 2008 EV is the centerpiece of the baseline plan, hence my original subject line. /dps |

It is also approximately the starting point for the Oberth maneuver for the trip to Mars or 2008 EV The trip to 2008 EV is the centerpiece of the baseline plan, hence my original subject line. So nobody here has been reading about the Landau-Strange-et-alia plan? (Merryl Azriel apparently has, with a brief mention in Space Safety Magazine at http://www.spacesafetymagazine.com/2...ics-engineers- explain-roadmap-crewed-mars-mission/) Here, by the way, is a set of slides at seti.org providing some additional data, with Jonathan Battat as an additional author: http://tinyurl.com/LandauSEPslides There a short list of potential asteroid destinations at ESA: http://www.esa.int/gsp/ACT/doc/MAD/p...-MAD-2010-(DPS) Humans2Asteroid.pdf Those two seem to come together at http://targetneo.jhuapl.edu/pdfs/sessions/TargetNEO-Session3-Landau.pdf /dps |
