Live coverage: Two satellites lift off aboard Ariane 5

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.

Launching for the 20th time from the jungle of South America, a Russian-built Soyuz booster rocketed into orbit Wednesday with a new eye in the sky for the French military, the first in a series of upgrades planned for the country’s defense satellites over the next five years.

SpaceX launched a Falcon 9 rocket at 5:37 a.m. PDT (8:37 a.m. EDT; 1237 GMT) Monday from Vandenberg Air Force Base in California with the third set of 10 new-generation satellites for Iridium’s voice and data relay network. The Falcon 9’s first stage booster successfully landed on a platform in the Pacific Ocean a few minutes after liftoff.
