... , payload transfer, orbital dynamics '''JBIS Reference Code ''' - 2006.59.368 '''Number of Pages''' - 7 Abstract A new concept for propellantless payload transfer from the surface of the Earth to Earth escape ... the underlying dynamics of the problem. It shown that an unconstrained payload at rest on a space elevator at synchronous radius is in an unstable equilibrium, and that this instability can ...

... macro-engineering initiatives related to lunar economic development and Earth's ecological sustainability. We propose a macroproject that will transfer collected seawater from the Arctic Ocean and compressed carbon dioxide gas ... (lake, ocean) will permit remarkable industrial transformations of the Moon's crust; carbon dioxide is a useful industrial gas, perhaps worthy of bulk transport to the Moon. Abstraction of carbon dioxide ...

... impact on its commercial viability, particularly as a means to overcome the investment trap. A strategy is outlined showing that a mixed market approach to passenger transport to orbit can both provide savings for government activity and tourist costs around half a million dollars per person. However to take advantage of this market synergy the orbital personnel ...

... Abstract In comparison with other large scale Space projects, "Space Tourism" requires only one development - a suitable, economic, Reusable Launch Vehicle (RLV). The high flight rates associated with "tourism" are expected ... economically attractive. However, currently projected RLV launch prices appear well above those affordable by tourists. A study of the economics of Space Tourism has been made using an Integrated Parametric System ...

... compatible radio protocols of current and projected Mars orbiters have enabled the gradual development of a heterogeneous constellation providing proximity communication services for surface assets. The current and forecasted capability of ... keeping burn rates, forecasted maneuver tasking, and anomaly resolution budgets. Orbiter reliability is estimated probabilistically. A flexible scheduling framework accommodates the projected mission queue as well as potential alterations. '''To BUY ...

... Abstract The Cassini/Huygens mission, to explore Saturn and its moons, was the result of a successful cooperation among the space agencies of United States (NASA), Europe (ESA) and Italy (ASI ... probe on Titan moon. The development of this challenging mission has requested the involvement of a large number of industries and research centres worldwide. Italian space community has been deeply involved ...

... ''' - 2007.60.122 '''Number of Pages''' - 7 Abstract This paper explores efficient ways to sustain a sizable colony on Mars. Various combinations of newly and previously discovered cycler and semi-cycler trajectories transport crews from Earth to a Mars base and back. It is assumed that the Mars base should never be abandoned ...

... Invitation to ETI group were called upon to evaluate, and ultimately perform laboratory testing of, a claim of extraterrestrial electromagnetic technology present on Earth. These tests were undertaken because, although the claims were highly questionable, the claimant himself seemed reasonably credible, and a positive outcome, though unlikely, could have tremendous payoffs. The claim was rigorously tested but this ...

... .60.209 '''Number of Pages''' - 10 Abstract The linear dynamics and stability analysis of reconfiguring a 2-spacecraft Coulomb tether formation is investigated. In this concept the tether between two craft ... can change its shape by modifying the desired reference length. As a result, the two-craft formation will essentially act as a long, slender, nearly-rigid body of variable length. Inter-spacecraft ...

Images are represented by measurements of their fractal dimension, fractal ...
