Rocket Lab’s fifth flight of the year is set for liftoff as soon as Wednesday (U.S. time) carrying a small experimental satellite to orbit for Astro Digital, a Silicon Valley company aiming to demonstrate technologies in space after an earlier focus on Earth observation.

Rocket Lab’s second mission of 2021 lifted off at 6:30 p.m. EDT (2230 GMT) Monday from New Zealand carrying six small satellites for customers in Australia and the United States, along with a test platform for a NASA small satellite mission to the moon launching later this year.

China launched the third in a series of experimental Shiyan 6 satellites April 8 aboard a Long March 4B rocket, beginning a mission to test new space technologies, including a new super-black coating to absorb stray light and improve the sensitivity of on-board optics.
