Live coverage: NASA confirms successful first flight of Mars helicopter

NASA has signed a $187 million contract with Northrop Grumman to complete the preliminary design of a pressurized crew habitat for the planned Gateway mini-space station near the moon, and agency officials have discussed new details about plans to launch first two Gateway modules on a single heavy-lift rocket.

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.

Maxar’s eagle-eyed WorldView 3 satellite captured high-resolution views Monday of NASA’s twin Apollo-era launch pads at the Kennedy Space Center in Florida, both now home to new launch vehicles 50 years after humans took their first steps on the moon.
