Tiangong 1 (Heavenly Temple 1) Launch
CZ-2FT1, Jiuquan SC
2011 Sep 29, 13:16
TianGong 1Successful launch of small laboratory, 8.5 tonnes mass (9 tonnes including fuel), to be used in docking experiments during visits by Shenzhou 8, Shenzhou 9 and Shenzhou 10. The last two will carry crews. Anticipated life is two years after which it will be de-orbited. Precise time: 13:16:03 UTC, at the beginning of a fifteen minute launch window. The date was on the third day of a potential launch period that was set after completion of the investigation into the 2011 Aug CZ launch failure with SJ-11-04. Launch on the first two days of the window was precluded by weather. Construction complete and ground testing commenced 2010 August. Launch postponed from 2010 Oct for technical reasons, and then again from a target date in the first half of 2011. Tiangong was taken to the launch site 2011 Jun 29.

2012 Jun 28, 07:30
After departure of Shenzhou 9, raised apogee by 13 km as start of move to higher 'storage orbit' and to await Shenzhou 10. The time is approximate.

Second part of manoeuvre following Shenzhou 9 departure raised perigee by 30 km to become the new apogee. Completion, of manoeuvre to higher 'storage orbit' to await Shenzhou 10: The time is approximate. Orbit history:

Tiangong 1 - Unusual Behaviour
on orbit
2012 Jul 10
Tiangong 1 entered a phase where onboard thrusters were operated at frequent intervals to affect the orbit. Either it has a problem or it is an orbit-control experiment. Notes:

Tiangong 1 - Orbit Adjustment
on orbit
2012 Aug 30, 13:10
Orbit raised in two-part engine firing in a 3-4 hour period centred around this time. Indicates that the launch date for Shenzhou 10 has been moved from a possible late-2012 to a 'probable' one early 2013 between late-Jan and late-Feb. New orbit is near-identical to 2012 July, immediately after Shenzhou 9 departure. Orbit parameters (see values for July 5 through to August 30): Orbital History in chart form:

Tiangong 1 - Thruster Firings cease
on orbit
2012 Sep 4
Tiangong 1's orbit decay rate no longer being controlled by onboard thrusters (see entry for July 10). Decay rate now following solar weather trend. Return to Shenzhou operating height will be early January. See plot (note that fluctuations follow the space weather trend):

Shenzhou Recovery Exercise?
Western China
2012 Sep 13
Could be practice, training or setting up equipment. Previous similar occurrence was nine weeks before launch of Shenzhou 9.

Tiangong On-orbit Checkout
on orbit
2012 Oct 8
About one week of minor disruptions to Tiangong's orbit parameters indicate periodic thruster firings - maybe a check of the vehicle's state of health. Can be seen on the plot here where the Tiangong data ceases to track the space weather trend:

Tiangong Orbit Boost
on orbit
2012 Oct 15, 11:45
Single firing of thrusters raises apogee by 10 km. Orbit goes from 346 x 353 km to 345 x 373 km. Tiangong 1's ground track was not passing near the Chinese mainland at the time so may have been a test of control via one of the Yuanwang tracking ships or a test of operating in an automatic mode. The time is approximate. Details in the entry here:

Tiangong Orbit Boost

2012 Oct 15, 18:25
Single firing of thrusters raises perigee by 12 km. Orbit goes from 345 x 373 km to 367 x 374. Completion of a two-part manoeuvre started earlier in the day, almost matching the highest orbit achieved by Tiangong 1 of 368 x 379 km during 2011 November. Details in the entry here:

Shenzhou 10 - China's Initial Planning
2012 Nov 10
Shenzhou 10 will be in orbit early-June 2013 and the crew may include a female astronaut. Mission length will be 15 days with 13 days docked with Tiangong 1. The plan allows for the mission to slip into July or August.

Tiangong 1 - Orbit Lowered
2013 May 21, 18:20
Manoeuvre in preparation for the Shenzhou 10 mission. Time is approximate and there is a slight possibility it occurred one revolution earlier - around 16:47 UTC. Orbit changed from from 339 x 334 km to 333 x 341 km to set up the ground track. Location is be 5-6 degrees to the east of the one used for the Shenzhou 8 and 9 missions. It allows for the use of an R-bar approach from below rather than the previous missions' approach from behind.

Shenzhou 10 Launch
CZ-2FT1, Jiuquan SC
2013 Jun 11, 09:38
Successful launch of piloted mission with crew Nie Haisheng, Zhang Xiaoguang, Wang Yaping (female). Aimed at docking with Tiangong 1. Mission set to run for fifteen days. Launch sequence UTC: 09:37:59 - Ignition 09:38:03 - liftoff 09:40 - launch escape tower jettison 09:40 - first stage boosters and core separation, stage 2 ignition 09:41 - fairing jettison 09:45 - CZ-2F stage 2 shutdown 09:47:34 - separation from launch vehicle 09:49 - solar panels open 09:50 - Tianlian comms aerial deploy Shenzhou entered orbit about 10,000 kilometres behind Tiangong 1. Date was the third launch opportunity in a seven-day-long window. Earlier dates were probably ruled out because Chinese president Xi Jinping was in California and was scheduled to be at Jiuquan for the launch.

Shenzhou 10 Docking
Tiangong 1
2013 Jun 13, 05:11
Shenzhou 10 began an automatic approach to Tiangong 1 at 02:48 UTC. Docking was followed by closure of latches between the two vehicles at 05:18 UTC. Docking was one minute later than the pre-launch estimate. The crew went aboard Tiangong 1 about three hours later, opening hatches at 08:17 UTC.

Shenzhou 10 - Undocking from Tiangong 1
on orbit

Shenzhou 10 undocked from Tiangong 1, carrying Nie Haisheng, Zhang Xiaoguang and Wang Yaping, in order to undertake a manually-controlled test approach and docking.

Shenzhou 10 - Manual Re-docking with Tiangong 1
on orbit
2013 Jun 23, 02:00
Culmination of test. At 01:50 UTC, Nie Hasheng was given the go ahead and initiated a manually controlled approach at 01:52 UTC from a position 140 metres in front of Tiangong. Docking at 02:00 was followed by the two vehicles being locked together at 02:07 UTC. The crew then re-entered Tiangong 1 at 05:09 UTC.

Shenzhou 10 Undocking
on orbit
2013 Jun 24, 23:05
Undocking from Tiangong 1 - carrying Nie Haisheng, Zhang Xiaoguang and Wang Yaping. Tiangong was above southern Africa and in view of the Swakopmund tracking station. Hatch closure occurred at 21:07 UTC when Tiangong 1 was above the Santiago, Chile tracking station. Time was about 22 minutes earlier than the timeline of the Shenzhou 8 and 9 missions. Followed by a fly-round of Tiangong 1 where both spacecraft manoeuvred to simulate varying approach/docking orientations including R-bar (approach from below). Shenzhou then reportedly re-docked briefly with Tiangong after approaching along the orbit from behind. It is unlikely that the docking ring was retracted to seal the interface. Tiangong 1 will continue in orbit but no more visits are planned. It will ultimately make a destructive re-entry over the Pacific Ocean.
