According to a statement from NASA, the launch was postponed from Sunday evening to this evening due to a ground support equipment cable failing to perform as expected during a pre-launch check out. The spacecraft is an Orbital ATK spacecraft, being sent up on a re-supply mission to the International Space Station.The last time an Antares rocket launch was attempted from Wallops Island was October 28, 2014.The two-state Antares rocket developed by Orbital ATK and carrying a Cygnus cargo ship to the International Space Station is scheduled to launch at 8:03 p.m. Sunday evening, weather conditions permitting. Sure, delivering supplies to the ISS probably doesn’t mean much to you, but witnessing a badass rocket launch could be pretty cool, right? The booster, created to put up to about 17,000 pounds (8,000 kg) into orbit close to Earth, flew four times successfully before the 2014 failure.But seven hours before the planned liftoff, NASA announced the flight was off until 7:40 p.m. Monday. “We have spares on hand and rework procedures are in process”.We’ll be able to see the Antares rocket in ascent with the second stage booster rocket firing at the point where the blue line meets the green line.NASA has also signed contracts with SpaceX and Boeing to begin launching astronauts to space in the next two years.If the weather is clear, the brilliant rocket burn of the Antares will be visible from far and wide as the rocket climbs towards space, potentially even as far away as southern Ontario, southern Quebec, New Brunswick, Prince Edward Island and Nova Scotia. First sighting times are expressed as a number of seconds after launch.Be part of the adventure! Include where you’re watching from, the time you spotted it, and how high in the sky you saw it climb.
