The Neil Gehrels Swift Observatory, which NASA sent into orbit to study the most powerful explosions in the universe, is re-entering the Earth’s atmosphere after a mission of approximately 22 years.
A large part of the spacecraft, which weighs approximately 1,450 kilograms, will burn up and disappear as it passes through the dense atmosphere. However, NASA predicts that some parts may reach the earth. It was announced that the probability of harm to anyone on earth is very low, this risk is 1 in 2,100.
The area where debris may fall covers the zone between 20.6 degrees north and 20.6 degrees south of the equator. This area; It includes Central and South America, central Africa, southern India, Southeast Asia, northern Australia and large oceanic stretches. While the exact drop time is not yet clear, experts point out the uncertainty in the models.
THE RESCUE OPERATION WAS INCONCLUSION
A daring rescue mission was launched in July to prevent the observatory’s uncontrolled fall. The aim was to capture the telescope and take it to a safe orbit with a special spacecraft called LINK. However, the operation ended in failure when this vehicle went out of control.
Increased activity on the Sun and expansion of the atmosphere increased the friction on Swift, accelerating the process of its descent. Scientists ended their data collection activities by sending the last command to the observatory in the past weeks.
A SIGNIFICANT GAP IN THE WORLD OF SCIENCE
Launched in November 2004, Swift Observatory played a critical role in examining sudden and powerful cosmic events in the universe, especially gamma ray bursts. The lack of a ready-made observatory to replace it is considered a significant shortcoming in terms of space research.
NASA continues to work on new collaborations and rescue missions with commercial companies in order to extend the life of such spacecraft.
