... presented. Expressed in terms of radii only, the determination of the time of flight along a parabolic trajectory for lunar and planetary flights is shown to be very convenient, especially when ... canonical units. Given the true anomaly and the periapsis distance, the time of flight in a given central force field is readily determined from Barker's Equation. The inverse problem, that ... the numerical accuracy of the solution of the cubic equation for the true anomaly . Here a solution for Barker's Equation, valid for all flight times is presented. '''To BUY this ...

... systems much smaller (< 5 kg mass, < 10m sail diameter) than existing sails, while still having a high delta-V and acceleration capability. With these unique capabilities of miniature Solar Sails, called ... dynamic evolution of energetic particle distributions of the rotating geomagnetic tail of Earth. With a unique design, a Solar Kite proves to be an efficient, affordable and versatile solution for the mission ...

Since cell metabolism is a target of the peptide, we have treated HeLa cells with DADLE and investigated its possible ... is able to reduce the nucleoplasmic transport of RNA, thereby suggesting that the opioid acts a depressor of cell function in vitro. In in vivo experiments, rats acutely injected with DADLE ... is able to depress metabolic activities at the organism level. The potential of DADLE as a hibernation induction factor in mammals which are not natural hibernators (inclusive of the human) deserves ...

Given the immediate future of manned space flight is to maintain ISS operations combined with a range of exploration objectives beyond earth orbit, it is clearly not viable to develop specialist ...

... larger planets and moons already visited and also the "undifferentiated rocks" of the smaller asteroids. A micromission approach to their exploration would take advantage of developments in equipment miniaturization and new technologies, using a sharply focussed mission objective to reduce spacecraft size and mission costs. An example micromission to ...

... design can be implemented during the very first manned mission. The proposed habitat will have a cylindrical shape and will consist of three parts: semispherical aluminium end caps, an aluminium cylindrical middle part and a cylindrical part made from locally produced glass. The semispherical end caps and the aluminium middle ...

The Space Elevator is now a real engineering project and is indeed one of the latest projects being considered within NASA ... the Space Elevator survival problem will change the issue from one that seems overwhelming to a recognizable risk issue that is well within current technologies and operational approaches. The expectation of ...
