DUBLIN, October 20. /TASS/.  A new computer model that will help the scientists to increase orbiter defense from clashing with space junk has been developed in Ireland. The researchers from the country’s oldest university Trinity College reported that “new mathematical methods will help predict emergencies in terrestrial space”.

According to one of the project initiators, Computer Science School Professor of Statistics, Simon Wilson, due to development in IT sphere they also managed to create new tools that will calculate more accurately impact points of satellite parts that didn’t burn in dense atmosphere. “Particularly, we are now able to calculate with higher probability whether objects in dense atmosphere will burn or not,” he pointed out. Other details will be kept secret until researchers get international patent. It is known that European Space Agency is interested in the invention.

The main challenge that experts from Trinity College face is not to let the most pessimistic scenario of the Hollywood blockbuster “Gravity”, which came out in 2013, materialize. The plot of the movie describes how all crew members of shuttle “Columbia” die during the routine mission in space exactly because of the collision of spaceship with extraneous objects.

Experts estimate that total weight of space junk exceeds 100,000 tons nowadays.

This entails satellite fragments, rocket stages, inactive spacecrafts and its pieces. All this debris gradually moves on lower orbits, posing a danger for manned missions.
