Live coverage: Atlas 5 countdown and launch journal

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.

The new Cygnus XL spacecraft will deliver more than 11,000 pounds (4,990 kg) of food, science supplies and cargo to the International Space Station. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 6:11 a.m. EDT (2211 UTC).

Wrapping up 109 days attached to the International Space Station, a Northrop Grumman Cygnus supply ship departed the orbiting research lab Tuesday to begin an extended four-month mission for additional technology demonstrations and smallsat deployments.
