STS-135: The final shuttle launch

Rocket Lab’s Electron booster launched six small satellites and a drag sail demonstrator to orbit Sunday from New Zealand, a success on the company’s first commercial mission that officials said should pave the way for a launch carrying NASA CubeSats next month and up to 16 flights of the light-class rocket next year.

Another satellite to join the China’s independent global navigation network successfully launched Saturday from the mountainous Xichang spaceport in the southwest of the country.

In the last few months, teams of SpaceX engineers working on the flat coastal plains of South Texas and in a nondescript industrial yard on Florida’s Space Coast have been building two futuristic-looking stainless steel rockets — or Starships — prototypes for a reusable vehicle the company claims could one day ferry people to Mars.
