Researchers from the University of British Columbia (UBC) in Canada say (via PTI) that informed that governments are required to take collective action and issue orders that rocket wrecks or parts be safely guided back to Earth after their use, which could increase launch costs. , but could potentially save lives.
Michael Byers, a professor in UBC’s Department of Political Science and lead author of the study, said, “Is the loss of human life allowed to be treated only as the cost of doing business, or is it something we need to avoid when we can? Should? And that’s the important point here: we can protect against this risk.”
The researchers noted that when objects such as satellites are launched into space, they use rockets, parts of which are often dropped into Earth orbit.
Byers believes that if these remaining parts of the rocket orbit too low, they could re-enter the atmosphere uncontrollably. Most parts would burn up in the atmosphere, but potentially lethal pieces could fall toward the ground. The study, published in the journal Nature Astronomy, analyzed more than 30 years of data from a public satellite catalogue, and calculated the potential risk to human life over the next 10 years.
Experts also looked at rates of uncontrolled rocket body re-entry, their orbits and human population data. Using two different methods, they found that current practice has a 6 to 10 percent chance of one or more occurrences in the next decade, if each re-entry spreads hazardous debris over an average area of 10 meters square. .
This calculation has been made taking into account the people on the ground, while Byers said we should also consider what would happen if a piece of debris hit an airplane during flight?
Study co-author Aaron Boley, an associate professor at UBC, said: “The risks have so far been assessed on a per-launch basis, which gives people a realization that the risk is so small that it can be taken into account.” Can be safely ignored. But the risk of a frequent occurrence is not that small.” He added, “So far no casualties have been reported, and there is no mass incident, but are we waiting for that moment and then will react, especially when it involves human life, or should we be aware of it? Should you try to come forward?”<!–
