Between 9:39 a.m. and 10:33 a.m. EDT, a SpaceX Falcon 9 rocket will attempt to launch the first batch of a new constellation of small commercial satellites for New Jersey-based Orbcomm Inc.

The rocket will carry the first six of Orbcomm's 17 OG2 satellites, which from low Earth orbit will provide machine-to-machine (M2M) communications for customers in the transportation and distribution, heavy equipment, oil and gas, maritime and other industries.

Sunday, May 11, is a backup launch date.

The rest of the OG2 satellites, built by Sierra Nevada Corp., are expected to be launched on another Falcon 9 later this year.
