Indian engineers called off the launch of the Chandrayaan 2 lunar landing mission Sunday after observing a “technical snag” during the final hour of the countdown, India’s space agency said.

Despite a growing number of rocket options, the availability of on-time launch services remains a key factor in getting BlackSky’s constellation of Earth-imaging smallsats into orbit. SpaceX’s rideshare launch service will give BlackSky a chance to add two more spacecraft to its fleet on a Falcon 9 rocket with the next batch of Starlink Internet payloads.

A secret Chinese military payload, believed to be a surveillance satellite, successfully flew into space Sunday aboard a Long March 4C rocket on China’s 39th and final scheduled orbital launch attempt of the year.
