Ne contaminons pas la planète Mars !

Un projet d'astrobiologie vise à ensemencer une des lunes de Mars. Ce défi spatial risquerait bien de contaminer la planète rouge ! Inadmissible quant à la protection de cette planète qui abrite peut-être une forme de vie primitive.

Avatar's moon Pandora could be real

This artist's conception shows a hypothetical gas giant planet with an Earth-like moon similar to the moon Pandora in the movie Avatar. New research shows that, if we find such an "exomoon" in the habitable zone of a nearby star, the James Webb Space Telescope will be able to study its atmosphere and detect key gases like carbon dioxide, oxygen, and water. The key is to find a planet that transits its star, and then find a moon orbiting that planet more than one stellar radius away, so that the moon can be studied independently of the planet. Moreover, an alien moon orbiting the gas giant planet of a red dwarf star may be more likely to be habitable than tidally locked Earth-sized planets or super-Earths. Credit: David A. Aguilar, CfA

Possibility of the Space Propulsion System Utilizing the ZPF Field

AIP Conf. Proc. 1103, 194 (2009)
Published online: March 16, 2009
DOI: 10.1063/1.3115495

According to the gravity theory proposed by H. E. Puthoff, gravity is a form of long-range van der Waals force associated with the Zitterbewegung of elementary particles in response to zero-point fluctuations (ZPF) of the vacuum and the inertia mass is arisen from the interaction with the vacuum electromagnetic zero-point field. From the standpoint of the ZPF field theory, the author studied the possibility of the space propulsion system, which is based on interactions between the zero-point field of the quantum vacuum and high potential electric field. By the theoretical analysis, it is considered that impulsive high potential electric field can produce a sufficient momentum for the spacecraft, which would permit interstellar travel instead of conventional chemical rockets.
