A satellite returned to Earth after more than 38 years of service

ERBS was published in 1984, and specifically made it possible to assess the extent of the hole in the ozone layer. It re-entered the atmosphere overnight from Sunday to Monday, over the Bering Sea.

The US Space Agency said, in a press release reported by many media outlets, that a decommissioned satellite belonging to the US Space Agency (NASA) has returned to the Earth’s atmosphere after spending more than 38 years in orbit around the blue planet. CNN.

The Earth’s Radiation Budget Satellite, known as ERBS, was launched on October 5, 1984 by the space shuttle Challenger. Its mission was to study how the earth absorbs and transfers energy from the sun. The data collected by the ERBS also made it possible to measure the thickness of the ozone layer as well as the amount of water vapor, nitrogen dioxide and aerosols in the Earth’s stratosphere.

One of the instruments aboard the satellite, the Stratospheric Aerosol and Gas Experiment II (SAGEII), collected valuable data confirming ozone depletion on a global scale. An awareness that led to the creation of the Montreal Protocol to protect this part of the stratosphere.

10 times longer life than expected

The aircraft re-entered Earth’s atmosphere over the Bering Sea at 11:04 p.m. EDT. Neither NASA nor the US Department of the Army has determined whether or not ERBS completely disintegrated during re-entry into the atmosphere.

ERBS was initially deployed for two years, and finally ran until 2005, that is, for 21 years.
