Science idea: Asteroids can take humans to other planets. Like an interplanetary bus…

[The idea also has serious problems with it. It might be impractical. But it is an interesting line of thinking. Jan]
Humans are trying to reach Mars, but a trip on board a spacecraft will cost a lot of money and time, besides tackling several other logistical matters, such as how to battle harmful levels of radiation. Researchers from Ukraine have come up with an innovative way to travel to the red planet – hitchhike your way to a planet on an asteroid.
Asteroids zoom past several planets in the universe and the scientists see it as a solution the cosmos already presents to humans who wish to travel between planets. So why not hop on them to reach Mars?
A trip to Mars will have a huge effect on the physical health of astronauts. It is around 225 million km away from Earth and a journey to and fro will take about three years. This means prolonged exposure to radiation and microgravity, leading to loss of muscles and bone density. Returning to Earth’s gravity will likely become impossible and heart issues are also likely to crop up.
AS Kasianchuk and VM Reshetnyk from the National University of Kyiv in Ukraine, authors of the paper, analysed the orbit of more than 35,000 near-Earth asteroids to understand the possibility of making successive approaches to pairs of planets Earth–Venus and Earth-Mars within a time range of 2020 to 2120.
They say asteroids can be used as interplanetary busses which will prove to be a much faster mode of transport between the planets. The researchers estimate the trips might even be completed within as soon as 180 days.
Several asteroids have been shortlisted
They have zeroed in on 120 candidates for Earth-Mars, Earth-Venus, Mars-Earth, Venus-Earth, and even Mars-Venus and Venus-Mars trips.
If the idea works out, it cancels out the need for creating a spacecraft to carry humans to other planers. However, a technological solution would still be needed to protect one against radiation.
The list of asteroids that can potentially help with planet-hopping will only grow since near-Earth objects are regularly discovered. NASA’s NEO Surveyor mission will prove to be of crucial help in this area as it is working to find more than 90 per cent of all NEOs larger than 140 metres in diameter.
Experts believe the right asteroid can prove extremely useful in the cosmic journey. Astronauts can possibly use it as a fuel station and seek shelter under features like caves to shield themselves from radiation.
Get a Free PDF Book: Did Six Million Jews really die in WW2?
This is a classic pamphlet that was written decades ago. This was one of the first serious attempts to question the Jewish holocaust claims of WW2. The German Ernst Zundel went to jail for printing this small book in Canada! Zundel did not write this. This was written by someone in Europe. The original questioning of the Jewish holocaust began in Europe. It was a French professor who had been in a Concentration Camp during WW2 who realised that Jews were making claims that were not true. That is how people slowly began to question the Jewish holocaust story.
Get a Free PDF Book: The Jews by Hilaire Belloc (1922)
This is one of the greatest analyses of the Jews that has ever been done. This book was published in 1922.Hilaire Belloc was a very prolific French writer and thinker. A wonderful aspect of this book is that it contains information about the Jews and their hideous deeds (e.g. in Russia) which Jews have tried very hard to completely remove from history. When you read this book you will realise that in 100 years, absolutely nothing has changed. He also hints at the Jews being behind the ‘South African War‘ (i.e. The 2nd Anglo Boer War).
Get a Free PDF Book: THE GREAT SOUTH AFRICAN LAND SCANDAL
This book includes photos and shows the horrors and incompetance and assorted foolishness that took place in South Africa when the ANC obtained farms from Whites through the Land Claims process. Nothing like this has been written since. It is a classic text on wastage and inefficiency.
