Q&A with Bruce Banerdt, principal investigator on NASA’s InSight mission (members only)

Taking aim on the International Space Station, nine kerosene-burning rocket engines powered a SpaceX Falcon 9 launcher into a clear sky over Florida’s Space Coast on Friday night to begin the final flight of the first version of the company’s Dragon cargo ship.

Rocket Lab counted down to the second test flight of its commercial Electron satellite launcher Monday, U.S. time, but a dramatic computer-commanded abort triggered moments after its engines ignited kept the light-class booster on its New Zealand launch pad for at least two more days.
