Live coverage: Vega rocket launches with LISA Pathfinder

NASA and SpaceX have set April 22 as the target launch date for the next Crew Dragon flight to the International Space Station. The four-person crew will be the first to ride a previously-flown Falcon 9 booster and a reused Dragon spacecraft, and a NASA official said this week that the launcher and capsule are in “really good shape” as refurbishment wraps up at Cape Canaveral.

As skywatchers and scientists converge on a transcontinental band of totality for Monday’s solar eclipse in the United States, engineers in Europe are building a unique pair of satellites to create artificial eclipses lasting for hours — a feat that that could be a boon for solar physicists but will escape the view of Earth-bound spectators.

Arianespace and CNES, the French space agency, have released sensational slow-motion video from shielded engineering cameras at the Ariane 5 rocket’s launch pad in French Guiana, showing the launcher’s fiery evening takeoff Feb. 5 with communications satellites for Saudi Arabia and India.
