A European re-entry demonstrator launched aboard a solid-fueled Vega rocket at 1340 GMT (8:40 a.m. EST) from French Guiana, kicking off a whirlwind 102-minute around-the-world test flight to validate technologies that could be used on future reusable launchers and spaceships.

A thick marine layer blanketing Vandenberg Air Force Base in California restricted views of SpaceX’s Falcon 9 rocket lifting off early Wednesday, but cameras fixed to the launcher provided spectacular imagery of the predawn departure with 10 Iridium satellites on-board.

A U.S. Air Force spokesperson said Friday that the military has not detected any objects deployed in orbit by a Chinese Long March rocket launch Wednesday, but China’s official media outlets still have not acknowledged the apparent failure.
