NASA has agreed to consider a Boeing proposal to extend the first piloted test flight of its commercial CST-100 Starliner crew capsule from two weeks to up to six months with an extra crew member for the International Space Station, hedging against potential delays that could jeopardize U.S. crew access to the orbiting outpost.

Rocket Lab’s first operational launch took off from Mahia Peninsula in New Zealand at 10:50 p.m. EST Saturday (0350 GMT Sunday). The Electron rocket is carrying six CubeSats and a tech demo payload into orbit for customers in the United States, Australia, and Germany.
