Live coverage: H-2A rocket lifts off from Japan with navigation satellite

Three spacecraft built in Europe and Japan have completed their final joint tests to ensure they are ready for departure to Mercury on an Ariane 5 rocket late next year on the nearly $1.9 billion BepiColombo mission to survey the solar system’s innermost planet.

The top secret intelligence-gathering payload for the U.S. government set for launch Tuesday on top of a Delta 4-Heavy rocket is likely the next in a line of sensitive eavesdropping satellites designed to intercept radio signals and other communications traffic from adversaries around the world.

SpaceX aborted an attempted flight Monday of the company’s Starhopper test rocket, a prototype for the company’s next-generation Starship vehicle. The hop test was to fly to a height of around 500 feet (150 meters) over SpaceX’s launch site at Boca Chica, Texas.
