NASA satellite crashed to Earth after spending 38 years orbiting our planet, CNN reports.. The Earth Radiation Budget Satellite (ERBS) was launched in 1984 aboard the Space Shuttle Challenger..

He worked until 2005, transmitting data to Earth that helped scientists understand how the planet absorbs and reflects solar energy, as well as measure concentrations of ozone, water vapor, nitrogen dioxide and aerosols in the stratosphere..

The US Department of Defense confirmed that the satellite entered Earth's atmosphere on January 8 over the Bering Sea.. Whether all of its parts will burn up in the atmosphere was initially unclear, the chance that it could cause damage on the ground was estimated at 1 in 9400. But the fall of the device was without problems..

The satellite itself worked much longer than expected.. He served 21 years instead of two planned. NASA said that the instruments of the apparatus were able to collect data confirming the destruction of the Earth's ozone layer.

This data helped shape the Montreal Protocol Agreement, which was signed in 1987 by dozens of countries.. It has dramatically reduced worldwide use of ozone-depleting chlorofluorocarbons (CFCs), chemicals once widely used in aerosol dispensers, refrigeration and air conditioners..

A 2021 study found that if a CFC ban had not been agreed, the world would be on track for ozone depletion and an additional 2.5 degrees Celsius of global warming by the end of the century.

Recall that the first ever launch of space satellites from the UK, which was produced by the Californian company Virgin Orbit, ended in failure.. The exact reasons for the failure of the mission are not called..
