An interstage adapter that connected the first and second stages will separate at T+plus 3 minutes, 59 seconds.<\/p>\n<p>The launcher\u2019s Castor 30XL solid-fueled upper stage will ignite at T+plus 4 minutes, 7 seconds, and generate up to 104,300 pounds of thrust during a burn lasting approximately 2 minutes, 45 seconds. The second stage motor will burn out at approximately T+plus 6 minutes, 52 seconds, then deploy the Cygnus spacecraft at around T+plus 8 minutes, 52 seconds.<\/p>\n<p>The spacecraft\u2019s two cymbal-shaped electricity-generating solar arrays will unfurl in a fan-like motion around two hours into the mission, and the ship\u2019s thrusters will begin fine-tuning its approach to the space station with a series of course-correction burns, setting up for a laser-guided final approach Sunday, Oct. 4.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This graphic illustrates the major events during the Antares rocket\u2019s climb into orbit with the Cygnus supply ship on the NG-14 mission.
