Interstellar Travel Project: Breaching Boundaries Beyond Our World
Introduction
Embarking on the ultimate exploration, the Interstellar Travel Project is an ambitious endeavor that aims to get humanity off this planet and into the cosmos. But what do we know about this revolutionary project? And ...
Abstract
Space travel has had a relatively short history. Despite its recency, the field has seen rapid
development over the last several decades. Once the domain of governments, space travel is now
also in the private sector. Since the first commercial human space flight took place in 2001,
several other wealthy space tourists purchased their rides into space. Currently, more than 625
people have signed up for sub-orbital space flights with Virgin Galactic [1]. However, there still
are significant barriers in making space travel a reality for the general public. This paper
examines and analyzes these problems and posits the problem of conventional propulsion system
as the central issue to target. Building upon these analyses, several alternative propulsion sources
are discussed as new solutions. Additionally, presentation was performed in front of general
public and surveys were conducted to assess the perceived accessibility of space travel to
ordinary people. Results indicated the study participants indeed considered space travel to be a
personally feasible aspiration when the problems related to cost, safety, and convenience were
resolved. All known interstellar transportation methods encounter monumental technological or
engineering roadblocks, or even rely on speculative unknown science. In particular light of the
recent public excitement and ensuing disappointment regarding the exotic \EM drive" it is
worthwhile to point out that propellant less space travel is eminently possible based on well-
established physical principles. Here a new mode of transport is proposed which relies on
electrical moderated momentum exchange with the ionized particles in the interstellar medium.
The application of this mechanism faces
Signiant challenges requiring industrial-scale exploitation of space but the technological
roadblocks are die rent than those presented by light sails or particle beam powered craft, and
may be more easily addressed depending on the uncertain march of technology.
Introduction
Interstellar space travel is manned or unmanned travel between stars. Interstellar travel is much
more difficult than interplanetary travel: the distances between the planets in the Solar System
are typically measured in standard astronomical units (AU)—whereas the distances between
stars are typically hundreds of thousands of AU, and usually expressed in light years. Because of
this some combination of great speed (some percentage of the speed of light) and huge travel
time (lasting from years to millennia) would be required. These speeds are far beyond what
current methods of spacecraft propulsion can provide. The energy required to propel a spacecraft
to these speeds, regardless of the propulsion system used, is enormous by today’s standards of
energy production. At these speeds, collisions by the spacecraft with interstellar dust and gas can
produce very dangerous effects both to any passengers and the spacecraft itself. A number of
widely differing strategies have been proposed to deal with these problems, ranging from giant
arks that would carry entire societies and ecosystems very slowly, to microscopic space probes.
Many different propulsion systems have been proposed to give spacecraft the required speeds to
, cross interstellar space: these range from different forms of nuclear propulsion, to beamed
energy methods that would require mega scale engineering projects, to methods based on
speculative physics.
Benefits of research
Our population on earth is increasing rapidly day by day and also over utilization of natural
resources which is causing pollution and people on earth cannot survive and searching for other
planate for habitation. We want to explore beyond our solar system and search a planet for
habitation. Interstellar travel is the only possibility of survival. We need to focus on one thing
i.e., our survival. Our nearest star alpha centauri has a planet favorable for life and its just 4.4
light years away. Scientists are trying to reach to that planet by 21 st century. They can go up to
10% of speed of light but it takes about 80-90 years to reach there, but we need to accelerate
about 50% of speed of light. The main benefit of this research is to save human race form
extension. There are still many scientist who are working on travelling from one star to another.

Rocket Science
Current rockets use chemical fuels, these can be solids, liquids, or gases
Efficiency of a rocket measured with the
mass ratio = Mass with fuel / Mass without fuel
To escape the gravity of the Earth, need a mass ratio of ~39, single stage rockets have mass ratios of ~15 or less,
this is not enough, so we can’t leave the Earth
