It will take less than 10 minutes for a Long March 2F rocket to send two astronauts inside the Shenzhou 11 space capsule on course toward a docking with China’s Tiangong 2 space lab.
The 191-foot-tall (58-meter) rocket is scheduled to blast off from the Jiuquan space center in northwestern China’s Inner Mongolia territory at 2330 GMT (7:30 p.m. EDT), or around sunrise Monday at the launch site.
Astronauts Jing Haipeng and Chen Dong will be aboard the Shenzhou 11 spaceship, beginning a 33-day mission in orbit.
T-0:00:01: Ignition
The Long March 2F rocket’s first stage and four liquid-fueled boosters ignite and throttle up to 1.4 million pounds of total thrust.
T-0:00:00: Liftoff
The 191-foot-tall (58-meter) Long March 2F rocket lifts off from the Jiuquan satellite launching center.
T+0:00:12: Pitch and roll program
The Long March 2F rocket begins a pitch-over maneuver to steer on the proper heading toward orbit.
T+0:02:35: Escape tower jettison
The launch abort system, which would be used by the crew to escape the Long March rocket in the event of a mishap, is jettisoned after it is no longer needed.
T+0:02:35: Booster separation
Moments after the boosters drain their hydrazine and nitrogen tetroxide propellant, the rockets are jettisoned from the Long March 2F first stage.
T+0:02:40: First stage separation
The Long March 2F first stage separates about four seconds after the strap-on boosters are jettisoned. The second stage ignites moments later.
T+0:03:30: Fairing separation
The aerodynamic shroud covering the Shenzhou 9 spacecraft is released once the Long March rocket flies out of the lower atmosphere.
T+0:08:45: Shenzhou 11 separation
The Shenzhou 11 spacecraft separates from the second stage of the Long March 2F rocket. The launch is targeting an orbit with an inclination of 42.8 degrees. Shenzhou 11’s power-generating solar panels will be extended a few minutes later.
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.
Aiming to reduce risk and costs, NASA has decided to launch the first two modules of the Gateway station in lunar orbit on the same heavy-lift rocket in 2023, rather than fly them on separate rockets and dock them together in deep space, according to the the agency’s chief human spaceflight manager.
Three robotic Mars missions launched from Earth last month have begun fine-tuning their trajectories through the solar system with the first in a series mid-course corrections to take aim on the Red Planet for arrival next February.
