Pujiang-1, also known as PJ-1, is a Chinese technology demonstration satellite [1] designed to promote the construction of smart cities in China. [4] PJ-1 also monitors weather, traffic and population density of a city. It is the first Chinese satellite that uses 3D printing for the titanium structure of its antenna. [5] It also features a Wi-Fi router providing a communication network between satellites. [3]
PJ-1 was launched on 25 September 2015 at 1:41 UTC from the Jiuquan Satellite Launch Center (JSLC) in China.
The launch rocket Chang Zheng 11 (Long March 11) delivered PJ-1 satellite into a Sun-synchronous orbit (SSO) at an altitude of about 299 miles (481 km), inclined 97.3 degrees.
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development.
The Long March 2C (LM-2C), also known as the Chang Zheng 2C (CZ-2C), is a Chinese orbital launch vehicle, part of the Long March 2 rocket family. Developed and manufactured by the China Academy of Launch Vehicle Technology (CALT), the Long March 2C made its first launch on 9 September 1982. It is a two-stage launch vehicle with storable propellants, consisting of Nitrogen Tetroxide and Unsymmetrical Dimethylhydrazine. The launch vehicle was derived from the DF-5 ICBM.
This article outlines notable events occurring in 2005 in spaceflight, including major launches and EVAs. 2005 saw Iran launch its first satellite.
The year 2007 contained several significant events in spaceflight, including a Chinese ASAT test, the launches of the US Phoenix and Dawn missions to study Mars and Asteroid belt respectively, Japan's Kaguya Lunar orbiter, and the first Chinese Lunar probe, Chang'e 1.
1971 saw the last three known deaths of cosmonauts of the Soviet space program and the only deaths in space. Their mission was to man humanity's first space station. The experimental bay door failed to separate so the first crew failed to dock and second crew were killed on re-entry. 1971 also saw the launch of the first and only British satellite on top of a British rocket after that success the program was cancelled.
The year 2008 contained several significant events in spaceflight, including the first flyby of Mercury by a spacecraft since 1975, the discovery of water ice on Mars by the Phoenix spacecraft, which landed in May, the first Chinese spacewalk in September, the launch of the first Indian Lunar probe in October, and the first successful flight of a privately developed orbital launch vehicle by SpaceX's Falcon 1.
The Long March 4B, also known as the Chang Zheng 4B, CZ-4B and LM-4B is a Chinese expendable orbital Launch vehicle. Launched from Launch Complex 1 at the Taiyuan Satellite Launch Center, it is a 3-stage launch vehicle, used mostly to place satellites into low Earth orbit and Sun-synchronous orbits. It was first launched on 10 May 1999, with the FY-1C weather satellite, which would later be used in the 2007 Chinese anti-satellite missile test.
Several significant events in spaceflight occurred in 2009, including Iran conducting its first indigenous orbital launch, the first Swiss satellite being launched and New Zealand launching its first sounding rocket. The H-IIB and Naro-1 rockets conducted maiden flights, whilst the Tsyklon-3, Falcon 1 and Ariane 5GS were retired from service. The permanent crew of the International Space Station increased from three to six in May, and in the last few months of the year, Japan's first resupply mission to the outpost, HTV-1, was conducted successfully.
The year 2010 saw a number of notable events in worldwide spaceflight activities. These included the first test flight of the SpaceX Dragon commercial resupply spacecraft, which is intended to resupply the International Space Station (ISS), and the maiden flights of the Falcon 9 and Minotaur IV rockets. In June 2010, South Korea conducted a second Naro-1 launch, after the failure of the rocket's maiden flight in 2009; however, the second attempt also failed. The Kosmos-3M was retired from service, making its final flight in April. The Molniya-M was also retired from service, making its final flight in September.
This comparison of orbital launch systems lists the attributes of all individual rocket configurations designed to reach orbit. A first list contains rockets that are currently operational or in development; a second list includes all retired rockets. For the simple list of all conventional launcher families, see: Comparison of orbital launchers families.

Several Asian national space programs are attempting to achieve the scientific and technological advancements necessary for regular spaceflight, as well as to reap the strategic and economic benefits of space capability. This is sometimes referred to as the Asian space race in popular media, an allusion to the Cold-War-era Space Race between the United States and the Soviet Union.
The year 2011 saw a number of significant events in spaceflight, including the retirement of NASA's Space Shuttle after its final flight in July 2011, and the launch of China's first space station module, Tiangong-1, in September. A total of 84 orbital launches were conducted over the course of the year, of which 78 were successful. Russia, China and the United States conducted the majority of the year's orbital launches, with 35, 19 and 18 launches respectively; 2011 marked the first year that China conducted more successful launches than the United States. Seven crewed missions were launched into orbit during 2011, carrying a total of 28 astronauts to the International Space Station. Additionally, the Zenit-3F and Long March 2F/G carrier rockets made their maiden flights in 2011, while the Delta II Heavy made its last.
Yaogan is a broad term used by the People's Republic of China to refer to its military reconnaissance satellites. Although officially described as being used for scientific experiments, crop yield estimation, and disaster prevention, Yaogan satellites are largely known to primarily support Aerospace Reconnaissance Bureau of the Second Department of the General Staff of the People's Liberation Army (PLA). Yaogan satellites are the successor program to the Fanhui Shi Weixing (FSW) recoverable reconnaissance satellite program but, unlike its predecessor, includes a variety of classes utilizing various means of remote sensing such as optical reconnaissance, synthetic aperture radar (SAR), and electronic intelligence (ELINT) for maritime surveillance. Yaogan satellites have been launched from the Taiyuan Satellite Launch Center (TSLC) in China's northern Shanxi Province, the Jiuquan Satellite Launch Center (JSLC) in China's Inner Mongolia Autonomous Region, and the Xichang Satellite Launch Center (XSLC) in Sichuan Province.
Shijian 11-01 is a Chinese technology demonstration satellite which was launched in November 2009. It was built by the Aerospace Dongfanghong Satellite Company, and is being operated by the China Aerospace Science and Technology Corporation.
INSAT 3E is a defunct communication satellite built by Indian Space Research Organisation. It was launched on September 28, 2003 from the European Space Agency's spaceport in French Guiana on board the Ariane rocket. The satellite had a launch mass of 2750 kilograms. It is the 4th satellite launched in the INSAT-3 series for INSAT. It was designed for providing high-speed communication, Television, VSAT & Tele-education services and was an important landmark in Indian Space Programme.
In 2015, the maiden spaceflights of the Chinese Long March 6 and Long March 11 launch vehicles took place.

Gaofen is a series of Chinese high-resolution Earth imaging satellites for the China High-resolution Earth Observation System (CHEOS) program. Unlike the Yaogan program of military reconnaissance satellites, CHEOS is a state-sponsored, civilian Earth-observation program used for agricultural, disaster, resource, and environmental monitoring. Proposed in 2006 and approved in 2010, the CHEOS program consists of the Gaofen series of space-based satellites, near-space and airborne systems such as airships and UAVs, ground systems that conduct data receipt, processing, calibration, and taskings, and a system of applications that fuse observation data with other sources to produce usable information and knowledge.
