According to a new study by researchers at the University of British Columbia, there91裸聊视频檚 a six to 10 per cent chance rocket 91裸聊视频榡unk91裸聊视频� may re-enter the Earth91裸聊视频檚 atmosphere and could even severely injure or kill a human.

The study was a joint collaboration between professors in the university91裸聊视频檚 departments of political science and physics.

The researchers say governments need to take collective action to mandate rocket junk be guided safely back to Earth after use. They say such a mandate would inevitably increase the cost of launches but should be a necessary cost.

While the risk to any one person is very low 91裸聊视频� being struck and killed by space junk should not be high on your personal list of worries 91裸聊视频� the researchers still believe it is dangerous enough to warrant being addressed and easy enough to solve, albeit somewhat expensive.

91裸聊视频淲hat we91裸聊视频檙e proposing is entirely feasible and there91裸聊视频檚, therefore, no excuse for delaying action on this matter,91裸聊视频� said Michael Byers, a professor of political science at UBC and the lead researcher on the project.

Technological advancements in space travel now include engines that can reignite as well as extra fuel which can aid in guiding debris to remote areas of the oceans. In addition to the potential threat that it poses to humans, space junk remaining in orbit can also cause significant property damage.

In 2020, a 12-metre long pipe fell from the sky and struck the Ivory Coast village of Mahounou, causing damage to local buildings.

As a vast nation, Canada is at an increased risk of being hit by debris.

In 1978, a nuclear-powered Soviet satellite, falling back to Earth, scattered potentially radioactive debris into the Northwest Territories, Alberta and Saskatchewan.

The cleanup project that ensued, called 91裸聊视频極peration Morning Light91裸聊视频�, ended up costing nearly $14 million. Canada had originally sought $6 million from the Soviet Union but only ended up receiving $3 million.

Because of the Earth91裸聊视频檚 rotation, it is unlikely the nation launching a spacecraft will also be the one that suffers the consequences of its debris.

Despite most spacecraft being launched from the global north, the researchers found the global south disproportionately bears the risk of being struck by space junk because of the earth91裸聊视频檚 tilt and rotations.

The study found the latitudes aligned with Jakarta, Dhaka and Lagos are approximately three times more likely to be struck by debris than those of New York, Moscow and Bejing.

Byers suggests following the model of international collaboration that took place after the Exxon Valdez oil spill in 1989 and the Montreal Protocol, a 1987 treaty that phased out the use of substances causing rapid ozone depletion.

91裸聊视频淏oth required some cost to change practice, but in response to new scientific analysis, there was a collective will to do so,91裸聊视频� said Byers. 91裸聊视频淚n both instances, they were complete successes.91裸聊视频�

According to NASA, there are 27,000 pieces of orbital debris being tracked by the American government. However, 91裸聊视频渕uch more debris, too small to be tracked but large enough to threaten human spaceflight and robotic missions, exists.91裸聊视频�

Spacecraft and debris both travel at extremely high speeds (upwards of 25,000 km/h) so even a small piece of debris could create big problems, NASA indicates.

As of 2017, the United States in orbit with 3,999. Russia was a close second, with 3,961 pieces of debris (including items from the Soviet Union).

Proportionally, of space junk, with 7.5 pieces of debris objects per payload. The United States and Russia are responsible for 1.3 and 4.3 objects per payload, respectively.
