Live coverage: United Arab Emirates probe arrives in orbit around Mars

Scientists eager for answers to long-standing questions about the geology of Mars will get a lift Saturday with the blastoff from California of an Atlas 5 rocket with NASA’s InSight mission, a robotic landing craft that will take the pulse and temperature of the red planet.

Rocket Lab’s Electron rocket, a commercially-developed light-class booster, lifted off at 1:33 a.m. EST (0633 GMT) Sunday, carrying 13 CubeSats into orbit under contract to NASA.

A review of data captured by NASA’s Galileo spacecraft as it orbited Jupiter in the 1990s indicates it likely flew through a plume of water vapor spewing from cracks in the surface of the moon Europa, providing independent evidence water is being released from a vast sub-surface ocean beneath its frozen crust, scientists said Monday.
