ЦитатаTwo Chinese launches in 24 hours deliver Pakistan satellites, Beidou backup to orbitby Andrew Jones -- July 10, 2018A Long March 2C/SMA rocket lifts off from Jiuquan Satellite Launch Center at 03:56 UTC on July 9, 2018. Credit: CGWICHELSINKI, Finland -- China launched twice July 9, with an early Long March 2C launch of two satellites for Pakistan into low Earth orbit being followed up with a Long March 3A mission to back up China's Beidou navigation satellite system.The first launch saw the Pakistan Remote Sensing Satellite-1 (PRSS-1) lofted from the Jiuquan Satellite Launch Center in a desert region of Gansu province, northwest China, at 03:56 UTC July 9 (11:56 p.m. Eastern July 8 ).The optical satellite was put into a 588 by 624 kilometer orbit inclined by 98 degrees by the Long March 2C/SMA configuration which uses an upper stage.PRSS-1 was developed by the China Academy of Space Technology (CAST) and is based on a CAST-2000 satellite bus. Its imaging system provides panchromatic and multispectral imaging at 1-meter and 4-meter resolution, respectively, with a swarth width of around 60 kilometers.It will be used for land and resources surveying, monitoring of natural disasters, agriculture research, urban construction and providing remote-sensing information for the establishment of the China-Pakistan Economic Corridor and in the Belt and Road initiative, according to Chinese state media.PRSS-1 was accompanied by the smaller PakTES-1A satellite, a scientific experiment satellite designed and developed by Pakistan's Space and Upper Atmosphere Research Commission (SUPARCO).CAST is a subsidiary of the China Aerospace Science and Technology Corporation (CASC), the main contractor for the Chinese space program, which also provided the launch service. CAST also stated it provided training to Pakistan personnel as part of the satellite package, with SUPARCO to operate PRSS-1 after on-orbit delivery.China has in recent years adopted a strategy of offering turnkey projects which include satellite manufacture and launch as well as possible financing mechanisms. The country has launched communications and other satellites for countries including Belarus, Laos, Venezuela, Bolivia and Nigeria.Pakistan Remote Sensing Satellite 1 undergoing testing (Credit: CAST)...The July 9 launches were China's 19th and 20th of 2018, with CASC aiming to carry out around 36 launches this year. The country's record number of launches in a single year is 22, set in 2016, which included one failure and another partial failure. Commercial launch companies could boost the number to around 40.The major upcoming government missions for the second half of the year include the return-to-flight of the heavy-lift Long March 5, which failed during its second flight last July and prompted a redesign of first stage engines, and the Chang'e-4 lunar far side soft-landing mission. Both are set for late 2018.
ЦитатаChina successfully launches two satellites for PakistanJuly 9, 2018 | Stephen ClarkA Chinese Long March 2C rocket lifts off Monday from the Jiuquan space center. Credit: XinhuaA Chinese Long March 2C rocket launched Monday with two satellites for Pakistan's national space agency, extending a partnership between the two countries' space programs.The Long March 2C booster lifted off at 0356 GMT Monday (11:56 p.m. EDT Sunday) from the Jiuquan space center in northwest China's Inner Mongolia region, according to the China Academy of Launch Vehicle Technology.CALT, China's primary launch vehicle developer, said the rocket successfully placed the two Pakistani satellites into polar orbit using a solid-fueled rocket motor mounted atop the two-stage hydrazine-burning Long March 2C booster.Satellite tracking data published by the U.S. military indicated the mission's two payloads were deployed into an orbit ranging between 364 miles (586 kilometers) and 388 miles (625 kilometers) above Earth, following a track tilted 98.1 degrees to the equator. Скрытый текст: Pakistan Remote Sensing Satellite 1 was the mission's primary payload.The PRSS 1 spacecraft was built in China by DFH Satellite Co. Ltd., a subsidiary of the China Academy of Space Technology, for Pakistan's national space agency, SUPARCO. Designed for to collect one-meter (3-foot) resolution imagery from orbit, PRSS 1 will support the monitoring of natural resources, environmental protection, disaster management and emergency response, crop yield estimation, and urban planning, according to China Great Wall Industry Corp., the Chinese state-owned company responsible for arranging commercial and international satellite and launch contracts.Officials said the new satellite will also provide remote sensing information for the establishment of the China-Pakistan Economic Corridor, an extensive multibillion-dollar infrastructure development project between the two nations.The PRSS 1 spacecraft during integration with its launch adapter. Credit: Government of PakistanChinese officials said PRSS 1 extended its solar panels after reaching orbit Monday, beginning a series of checkouts before the Pakistani-owned craft is declared operational. PRSS 1 is designed for a seven-year lifetime, and carries two cameras.An experimental Earth observation satellite named PakTES 1A, designed and built in Pakistan with contributions from South Africa, accompanied the PRSS 1 spacecraft on Monday's launch.China previously manufactured and launched the PakSat 1R communications satellite for Pakistan in 2011. The countries signed the agreement for the PRSS 1 mission in April 2016, modeled on an arrangement in which China built a pair of similar Earth-observing spacecraft for Venezuela.Monday's mission was China's 19th space launch of the year, all successful. It was also the first launch by a Long March 2C rocket on a commercial flight since 1999, when China launched the last of six missions with a pair of U.S.-owned Iridium communications satellites.
