5,000-Pound Satellite Successfully 'Deorbited' Wednesday

On Wednesday afternoon "a European Space Agency satellite reentered Earth's atmosphere over the North Pacific Ocean..." reports CNN, "and there have been no reports of damage, according to the agency."The agency's Space Debris Office, along with an international surveillance network, monitored and tracked the Earth-observing ERS-2 satellite throughout February to make predictions about the reentry, which occurred at 12:17 p.m. ET Wednesday. The ESA provided continuous live updates on its website. At around 50 miles (80 kilometers) above Earth's surface, the satellite broke apart due to atmospheric drag, and the majority of the fragments were expected to burn up in the atmosphere. The agency said it was possible that some fragments could reach the planet's surface, but the pieces didn't contain any harmful substances and likely fell into the ocean... The ERS-2 satellite had an estimated mass of 5,057 pounds (2,294 kilograms) after depleting its fuel, according to the agency. "Uncontrolled Atmospheric reentry has long been a common method for disposing of space objects at the end of their mission," said Tim Flohrer, head of the agency's Space Debris Office, in a statement. "We see objects similar in size or larger to ERS-2 reentering the atmosphere multiple times each year." The Earth-observing ERS-2 satellite first launched on April 21, 1995, and it was the most sophisticated satellite of its kind at the time to be developed and launched by Europe... In 2011, the agency decided to end the satellite's operations and deorbit it, rather than adding to the swirl of space junk orbiting the planet. The satellite executed 66 deorbiting maneuvers in July and August of 2011 before the mission officially concluded later that year on September 11. The maneuvers burned through the rest of the satellite's fuel and decreased its altitude, setting ERS-2's orbit on a trajectory to slowly spiral closer to Earth and reenter the atmosphere within 15 years. The chances of an individual person being injured by space debris each year are less than 1 in 100 billion, about 1.5 million times lower than the risk of being killed in an accident at home, according to the agency.
