LIVE - Orbital ATK CRS-7 Launch Coverage

New Delhi: Orbital ATK's Cygnus spacecraft launches aboard a ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida. Cygnus will deliver several tons of cargo including crew supplies and science experiments to the International Space Station.

The unmanned Cygnus cargo craft is carrying more than 7,600 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of the crew members.

NASA Television is providing multiple broadcasts around launch activities, beginning at 10 a.m. EDT on air and streaming at www.nasa.gov/ntv. These events will also stream live on the agency’s website at www.nasa.gov/live.

Also, ten minutes prior to liftoff, NASA TV’s YouTube channel will debut full, 360 coverage of the launch at http://youtube.com/nasatelevision.

Meanwhile, forecasters predict a 90 percent chance of “go” conditions for today's launch of Orbital ATK CRS-7 mission, with the possibility of cumulus clouds posing the primary concern.
