Video: Antares rocket returns to flight with new engines

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.

Russian ground controllers decided Tuesday to delay the docking of a Progress supply freighter to the International Space Station until Thursday after telemetry signals indicated two radar navigation antennas may not have deployed following the ship’s launch from Kazakhstan.

A Merlin engine designed for the version of SpaceX’s Falcon 9 rocket that will carry astronauts into orbit for NASA failed during testing Saturday in Texas, but the company said its upcoming launches will not be affected by the accident.
