Shenzhou 4 launched on December 29, 2002, was the fourth unmanned launch of the Chinese Shenzhou spacecraft. Carried on board were two dummy astronauts to test the life support systems. The spacecraft was equipped for a manned flight, even featuring a sleeping bag, food and medication. The windows were constructed of a new material that was designed to stay clear even after reentry to allow an astronaut to confirm that the parachutes have deployed properly.

- Shenzhou 4 launched on December 29, 2002, was the fourth unmanned launch of the Chinese Shenzhou spacecraft. Carried on board were two dummy astronauts to test the life support systems. The spacecraft was equipped for a manned flight, even featuring a sleeping bag, food and medication. The windows were constructed of a new material that was designed to stay clear even after reentry to allow an astronaut to confirm that the parachutes have deployed properly. It was said that the spacecraft flown on Shenzhou 4 had no major differences to that used on Shenzhou 5. It flew with the ability for manual control and emergency landing, systems needed for a manned flight. A week before the launch, astronauts trained in the spacecraft to familiarise themselves with its systems. Initially the spacecraft was in a 198 km by 331 km orbit inclined 42.4°. This was raised to 330 km by 337 km at 23:35 UTC on December 29. Also on January 4 and January 5 several smaller manoeuvres are thought to have taken place. The rate of orbital decay seemed higher after January 1 suggesting that the orbital module's solar panels may have been deployed for the first time. Compared to Shenzhou 3 the orbital period of Shenzhou 4 was much more tightly bounded with smaller manoeuvres. The launch of Shenzhou 4 was watched by officials including Chairman of the National People's Congress Li Peng; Vice Premier and member of the Politburo Standing Committee Wu Bangguo; Jia Qinglin, also a member of the Standing Committee; Cao Gangchuan, vice-chairman of the Central Military Commission; Song Jian, vice-chairman of the Chinese People's Political Consultative Conference; and Li Jinai, head of the General Armament Department of the People's Liberation Army. The spacecraft carried 100 peony seeds to investigate the effect of weightlessness on plants grown from them. The 52 experiments onboard investigated areas in physics, biology, medicine, earth observation, material science and astronomy. Four tracking ships were used for the mission — one off the coast of South Africa in the South Atlantic Ocean, one in the Indian Ocean near Western Australia, one in the North Pacific Ocean south of Japan, and one in the South Pacific Ocean west of New Zealand. The reentry module landed safely on about 40 km from Hohhot in Inner Mongolia. As with previous flights, the command for reentry to begin was given by a tracking ship off the coast of South Africa. It was thought before the flight that the Chinese could attempt a water landing to test the emergency system but this did not eventuate. The orbital module remained in orbit until September 9, 2003.
- Shenzhou 4 startete am 29. Dezember 2002 und war der vierte unbemannte Test des Shenzhou-Raumschiffs. Der Flug diente als Generalprobe für eine bemannte Mission der Volksrepublik China. Ausgestattet mit allen benötigten Subsystemen erging durch den erfolgreichen Test schließlich grünes Licht für die folgende bemannte Mission Shenzhou 5. An Bord des Schiffes befand sich erneut eine umfangreiche Sammlung an insgesamt 52 Experimenten und wissenschaftlichen Nutzlasten, speziell zu den Bereichen der Astrophysik, Erdbeobachtung, Mikrogravitation und Biotechnologie. Das beeindruckendste Experiment war jedoch ein an der äußeren Hülle angebrachter Laserreflektor, mit dessen Hilfe die Höhe des Meeresspiegels auf den Millimeter genau berechnet werden konnte. Mehrere Taikonauten hatten zuvor den Einstieg und die Bedienung der Steuerung trainiert. Der Kurs des Raumschiffs war außerdem so geplant gewesen, dass ein Rendezvous mit einem zweiten Shenzhou-Raumschiff möglich gewesen wäre. Die Landung erfolgte nach 108 Erdorbits bzw. sechs Tagen und 18 Stunden Flug am 5. Januar 2003 gegen 11.16 Uhr UTC, 40 Kilometer entfernt von Hohhot in der Inneren Mongolei. Nötig waren während des Flugs allerdings zwei größere und aufwändigere Bahnkorrekturen. An Bord waren zudem Astronautennahrung und persönliche Ausrüstung verstaut.
- Šen-čou 4 (čínsky 神舟; v přepisu pchin-jin Shenzhou 4; česky Božská loď 4) byl let se dvěma figurínami na lodi Číny. Let se uskutečnil v roce 2002. Návratový modul přistál v v oblasti vnitřního Mongolska.

- La Shenzhou 4 è una missione del programma spaziale cinese. Trasportava a bordo due manichini per testare i sistemi di supporto vitale in programma della prima missione con equipaggio: la Shenzhou 5. Il velivolo spaziale era equipaggiato con un sacco a pelo, cibo e kit per il pronto soccorso. Gli oblò erano costruiti con un nuovo materiale disegnato per rimanere pulito durante la fase di rientro in modo che il taikonauta potesse confermare l'avvenuta apertura dei paracadute. La Shenzhou 4 aveva anche i sistemi di controllo manuale necessari per un volo con equipaggio. Una settimana prima del lancio i taikonauti si addestrarono nella Shenzhou per familiarizzare con i suoi sistemi. Inizialmente la capsula era in un'orbita compresa fra 198 e 331 km con un'inclinazione. Alle 23:35 UTC del 29 dicembre 2002 l'orbita è stata portata fra 330 e 337 km. L'orbita è sembrata decadere il 1º gennaio probabilmente a causa del dispiegamento dei pannelli solari. Rispetto alla Shenzhou 3 l'orbita è stata più costante e sono servite meno manovre. Nella Shenzhou 4 erano stati caricati 100 semi di peonia per studiare l'effetto dell'assenza di gravità sulle piante. Sono stati eseguiti 52 esperimenti nei campi della fisica, della biologia, della medicina, dell'osservazione terrestre, della scienza dei materiali e dell'astronomia. Sono state usate quattro navi per la localizzazione della Shenzhou 4, una a largo della costa del Sud Africa nell'oceano Atlantico, una nell'oceano Indiano vicino all'Australia Occidentale, una nell'oceano Pacifico settentrionale a sud del Giappone ed una nell'oceano Pacifico meridionale ad ovest della Nuova Zelanda. Il modulo di rientro è atterrato con successo nella regione della Mongolia Interna. Come nei voli precedenti il comando per il rientro è stato dato dalla nave a largo del Sud Africa. Il modulo orbitale è rimasto in orbita fino al 9 settembre 2003.
- Shenzhou 4 var en ubemannet romferd, og den 4. ferden i det kinesiske Shenzhou-programmet siden 1999.
- Shenzhou 4 - czwarty lot kosmiczny statku typu Shenzhou. Lot rozpoczął się 29 grudnia 2002 o godz. 16.40 UTC. Lądowanie nastąpiło 5 stycznia 2003. W kabinie pojazdu znajdował się manekin ubrany w skafander kosmiczny i testowane były systemy podtrzymywania życia.
