Live coverage: Delta 2 launches

A SpaceX Falcon 9 rocket lifted off Tuesday with five communications satellites for Iridium’s commercial voice, data relay, and tracking network, and a pair of U.S.-German research craft to probe Earth’s climate and water cycle. Launch from Vandenberg Air Force Base, California, occurred at 12:47 p.m. PDT (3:47 p.m. EDT; 1947 GMT).

NASA is close to deciding whether to spend an extra $150 million to send the InSight lander to Mars in 2018 or cancel the mission after an instrument problem made the spacecraft miss a launch opportunity this year, with a verdict on the project’s future expected within weeks, officials said.

After the threat of lightning kept the mission on the ground Thursday, Arianespace and the European Space Agency successfully launched an Ariane 5 rocket Friday from Kourou, French Guiana, with the Jupiter Icy Moons Explorer mission, a robotic spacecraft embarking on an eight-year journey to the solar system’s largest planet. Liftoff with ESA’s JUICE spacecraft occurred at 8:14 a.m. EDT (1214 UTC).
