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.
Four astronauts strapped into their SpaceX Crew Dragon capsule, undocked from the International Space Station and plunged to a fiery pre-dawn splashdown in the Gulf of Mexico Sunday, closing out the first operational flight of SpaceX’s futuristic touch-screen ferry ship.
After scrubbing a countdown Saturday to review sensor data, Rocket Lab launched its first mission of 2021 from New Zealand at 2:26 a.m. EST (0726 GMT) Wednesday. The company’s light-class Electron rocket carried a super-secret payload for OHB, a German-headquartered satellite manufacturer.
Engineers are troubleshooting a small air leak aboard the International Space Station that was discovered last September, NASA reported Thursday. While it poses no safety threat, the lab’s three-man crew plans to seal themselves in the Russian segment of the station this weekend to help engineers pin down the leak’s location.
