Rocket Lab closed out its 2019 launch schedule Friday with the 10th flight of the company’s Electron small satellite launcher, successfully deploying seven payloads in orbit while demonstrating new re-entry guidance and control technology to move closer to recovering and reusing future boosters.

An atmospheric test model of Sierra Nevada’s Dream Chaser space plane is being readied for tow and landing tests at NASA’s Armstrong Flight Research Center in California this spring.

A senior NASA official said Tuesday that the Space Launch System, a huge heavy-lift rocket years behind schedule, could launch astronauts on a moon landing mission in 2024 on just its third flight to meet a goal announced last month by Vice President Mike Pence, while commercial companies will be entrusted with more responsibility to develop a lunar lander and a modest mini-space station, or Gateway, in lunar orbit.
