Home page of teodorov.... He believes optimal control is the path to robot movement.... Not AI!!!

Isn't it obvious! :)

I need to modify the first comment "He belives the path to AI goes through optimal control"... Big difference...

what a shame! ambition and innovation have not been fairly rewarded ...

I didn't have time yet. But formulating the failure with a MTBF or a FIT, you can easily imagine a more robust solution. Instead of one single burn, you would make several smaller burns - It will take more time and require more fuel though. Another "robust" approach is to consider weak stability boundary capture. Again it takes time, but chances of failure are lessen.

would be a pity indeed!

Wonder what is the most creative: the system or the name! NAUTILUS-X = Non-Atmospheric Universal Transport Intended for Lengthy United States X-ploration http://spirit.as.utexas.edu/~fiso/telecon/Holderman-Henderson_1-26-11/Holderman_1-26-11.ppt

If I could write, this is exactly what I would write about rocket, GO, and so on... :) "we are decadent and tired. But none of the bright young up-and-coming economies seem to be interested in anything besides aping what the United States and the USSR did years ago. We may, in other words, need to look beyond strictly U.S.-centric explanations for such failures of imagination and initiative. ... Those are places we need to go if we are not to end up as the Ottoman Empire of the 21st century, and yet in spite of all of the lip service that is paid to innovation in such areas, it frequently seems as though we are trapped in a collective stasis." "But those who do concern themselves with the formal regulation of "technology" might wish to worry less about possible negative effects of innovation and more about the damage being done to our environment and our prosperity by the mid-20th-century technologies that no sane and responsible person would propose today, but in which we remain trapped by mysterious and ineffable forces."

Would have been nice if it were historically more accurate and less polemic / superficial

mmmh... the wheel is also an old invention... there is an idea behind but this article is not very deepfull, and I really don't think the problem is with innovation and lack of creative young people !!! look at what is done in the financial sector...

Understanding life is the scientific focus of the next Europa/Ganimede mission!

the objective is rather the study of "emergence of habitable worlds", which of course includes understanding of life and what habitability is ...

better information from the ESA site: http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=42291

I don't put too many geeky stuffs here, but that may be a game to have a look at :) not that "The Space Game" wasn't "fun".

another hill to climb (in reference to a metaphor of a recent post)

Recents talks about NEO and human explorations. Some very interesting things.

I just can't see how their way of finding non-state funding for a 100 year project could work but would be happy to be surprised positively ...

Perhaps interesting for the SPS self-assembling

nice, read only the abstract so far but looks to me like a bit of 19th century crystallography reinvented ...

AsteroidWatch, a new NASA website about NEO for the public...

Extending quantum communication to space environments would enable us to perform fundamental experiments on quantum physics as well as applications of quantum information at planetary and interplanetary scales. Here, we report on the first experimental study of the conditions for the implementation of the single-photon exchange between a satellite and an Earth-based station. We built an experiment that mimics a single photon source on a satellite, exploiting the telescope at the Matera Laser Ranging Observatory of the Italian Space Agency to detect the transmitted photons. Weak laser pulses, emitted by the ground-based station, are directed toward a satellite equipped with cube-corner retroreflectors. These reflect a small portion of the pulse, with an average of less-than-one photon per pulse directed to our receiver, as required for faint-pulse quantum communication. We were able to detect returns from satellite Ajisai, a low-Earth orbit geodetic satellite, whose orbit has a perigee height of 1485 km.

hello Jose! Interesting it was proposed to do the same with the ISS as part of the ACES experiment. I don't remember the paper but i can look if you're interested

As I mentioned it into my thesis, this engine bridges the gap between chemical and low-thrust propulsion systems. To be more specific: Isp should vary between 1000 and 30000s, and the thrust amplitude should reach up to 1200 N. It is interesting to see that the concept is actually moving forward ...

interesting indeed! also for SPS!
