Tau Zero: In the cockpit of a Bussard ramjet
A Bussard ramjet is a relativistic spacecraft, fueled by fusion energy of cosmic matter that is collected during the flight. We derive the equation of motion of such a spaceship for a given mass…
Study of some parameters interstellar transport using of magnetic umbrella
Interstellar transport is an object of interest in many sci-fi stories. In history a lot of sci-fi predictions have turned into reality, such as communications satellites, deep-sea submarines and…

Direct Exoplanet Investigation using Interstellar Space Probes
- Geology, Physics
Experience in exploring our own solar system has shown that direct investigation of planetary bodies using space probes invariably yields scientific knowledge not otherwise obtainable. In the case of…
Maximizing specific energy by breeding deuterium
- Engineering, PhysicsNuclear Fusion
Specific energy (i.e. energy per unit mass) is one of the most fundamental and consequential properties of a fuel source. In this work, a systematic study of measured fusion cross-sections is…
Eternity in six hours: Intergalactic spreading of intelligent life and sharpening the Fermi paradox
On the technological horizon
The early years of the space programme saw the origination of the interstellar ramjet. During the heady 1960s and 1970s, this approach seemed more than capable of permitting human exploration and…
A comment on "the far future of exoplanet direct characterization"--the case for interstellar space probes.
- Physics, GeologyAstrobiology
It is argued that the presence of interstellar dust grains, while certainly something that will need to be allowed for in interstellar vehicle design, is unlikely to be the kind of showstopper suggested by Schneider et al.

Galactic Matter and Interstellar Flight
This paper describes a vehicle which uses the interstellar gas as a source of energyby nuclear fusionand as a working fluid. By this means high ship velocities and consequent short flight times can…
Interstellar Vehicle propelled by Terrestrial Laser Beam
IN a recent article Marx1 examined the possibility that interstellar travel may be accomplished in the lifetime of an astronaut. He pointed out that the attainment of relativistic velocities by a…
