SpaceX launched the first in a series of small satellite rideshare missions Sunday from Cape Canaveral, providing transportation for 143 U.S. and international spacecraft to low Earth orbit, a record number of satellites on a single flight. Liftoff occurred at 10 a.m. EST (1500 GMT) Sunday after bad weather forced SpaceX to scrub a launch attempt Saturday morning.

A United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral at 1:21 p.m. EDT (1721 GMT) with a satellite to replenish the U.S. Air Force’s Global Positioning System navigation network.

Seven Japanese and Vietnamese smallsats are set to ride Japan’s solid-fueled Epsilon launcher into orbit at 0050 GMT Friday (7:50 p.m. EST Thursday) on a mission that engineers say will demonstrate the light-class rocket’s ability to accommodate multiple payloads on a single flight.
