SpaceX and OneWeb — space industry rivals and owners of two of the largest fleets of commercial satellites — are set to add more spacecraft to their internet networks Wednesday with launches from Cape Canaveral and Russia.

SpaceX has concluded fatigue on an engine cover caused one of the nine Merlin 1D first stage engines on the company’s most recent launch to shut down early during ascent, leading to the loss of the booster during an offshore landing attempt in the Atlantic Ocean, an official said Monday.

A Russian Proton rocket lifted off Thursday from the Baikonur Cosmodrome in Kazakhstan with the AsiaSat 9 satellite destined to provide television broadcast, video networking and data delivery services over the Asia-Pacific region. Launch occurred at 1852:16 GMT (2:52:16 p.m. EDT), beginning a series of maneuvers expected to last nine hours before AsiaSat 9 is deployed from the rocket.
