CNN —Authorities in Sweden have retrieved the payload of a research rocket launched from the country’s Esrange Space Center that landed by error in neighboring Norway. It landed 15 kilometers (9 miles) across the Norwegian border — 40 kilometers (25 miles) northwest of the planned landing site — in a forested area that lies 1,000 meters (3,280 feet) above sea level. The rocket’s payload was recovered on Tuesday in good condition and transported by helicopter back to the Esrange Space Center in the north of Sweden. We are now investigating the reason why the rocket flew further northwest than (optimal). It is still too early to speculate about the cause, and we await more information from the current investigation,” Marko Kohberg, head of sounding rocket and balloon operations at Esrange Space Center, said in a Tuesday statement.
