We succeeded for the moon trip in 1969 itself, which is almost a half century ago. But the journey towards Mars still ambitious. You might aware of the obstacles for the astronauts, anyway let us recollect them first.
Our new space craft requires just half day reach moon (0.384403 million km) but it’s not the case for the deep travel to Mars, may require few months to strive since it’s 55 million km away from the earth. The atmosphere out of earth’s territory endangers the life by the destructive solar radiations like cosmic rays, etc, it’s also known as “solar winds or particle or plasma”. Ofcourse we are always lucky that earth has a giant Magnetic region called “Magnetosphere” which reflects and also refracts them in high degree of angle (see the picture) to save our lives from this radiations. Unfortunately our satellites and communication, and navigation waves are exposed for this plasma radiations, leading for the disrupted communication.
The idea has been around since 1969 (our first mission) that to carry a portable Magnetosphere with space craft for the Mars journey. However it’s impractical because the minimum of 100 Km of Magetosphere is only believed to work. But this turns to be a myth by the recent innovations of researchers. Experimental results from university of York, Uk based on nuclear fusion promises that it is possible to make a spectacular journey in solar storm by scattering highly charged, ionized particles from space craft.
In their experiments they used an apparatus which is originally build for fusion and they could demonstrate the potential viability of creating diamagnetic cavity (like earths Magnetosphere) for the spacecraft shielding and they have obtained promising results from the measurement of interaction between the flowing plasma and dipole magnetic field which ofcourse the shield of spacecraft.
