According to researchers from the University of British Columbia in Canada, the uncontrolled entry of a rocket into the atmosphere is more dangerous to the lives of people in poorer areas. However, this possibility is not related to the amount of money at all, but only to the location of the countries.
Research results
Rockets are used to launch satellites and other spacecraft and usually remain in orbit after launch. Most of the orbiters are located in the equatorial regions, and the debris uncontrollably falls to Earth. Because low-income countries are mostly located near the equator, the risk of dying from a rocket fragment is much higher. There is also a higher population density living in “unprotected or poorly guarded structures that provide limited protection from debris.”
The probability of debris falling in Jakarta, Dhaka, Mexico City, Bogota and Lagos is three times higher than in Washington, New York, Beijing and Moscow. – tell the authors of the work.
In preparing the study, the experts reviewed all available information regarding the fall of the debris over the past 30 years. They did not find any recorded cases resulting in human casualties. However, in their opinion, these data should not be trusted.
Imagine that in the countryside of a developing country, a small piece of metal fell from the sky and died mysteriously. Will it be announced as part of the rocket body? Will the world media learn about this event? – comment Michael Byers, professor at the University of British Columbia School of Political Science.
what to do with it
In light of this, scientists are proposing to force launch companies to manage the landing of rockets. This requires some fuel savings in the device for the return journey so that the rocket enters the atmosphere in a controlled manner over the desolate areas of the ocean.
Some organizations, like SpaceX, have lowered the bottom or first stage of their rockets back to Earth after launch, but the second stages used to launch satellites into their final orbits are still drifting in space with every chance of a free spin. fall into the atmosphere
