On May 27, 2019 at 06:23 UTC the “Soyuz-2.1b” rocket-carrier was launched from Plesetsk Cosmodrome, Arkhangelsk region, North Russia. The launch was performed by Russian Aerospace Defence Forces. The rocket equipped with the “Fregat” booster (upper stage) orbited the “Glonass-M” navigation satellite. The Russian GLONASS Global Navigation Satellite System – operated by the Russian Aerospace Defence Forces – is currently the only global alternative to the American GPS fleet in operation that has global coverage of comparable precision. The Russian Defense Ministry designed the new satellite “Kosmos-2534”, using the Russian military’s catch-all naming scheme for defense and intelligence spacecraft.
On May 24, 2019 at 02:30 UTC the "Falcon 9” rocket-carrier was launched from SLC-40 of Cape Canaveral launch site of US Air Force, Florida. The launch was performed by the "SpaceX” private company supported by the 45th Space Wing of US Air Force. The rocket orbited 60 “Starlink” satellites. The “Starlink” is a satellite constellation development project underway by US “SpaceX” company. The 60 small satellites will be joined by hundreds more “Starlink” spacecraft over the next year to fill out the network’s preliminary constellation. The “SpaceX” says that thousands of Starlink satellites may be launched to provide high-speed Internet services to consumers around the world.
On May 22, 2019 at 22:49 UTC (on May 23 by Beijing time) the “Long March – 4C” (“Changzheng-4C”) rocket-carrier was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province. The rocket was to orbit the “Yaogan-33” top secret military satellite. China’s official Xinhua news agency reported that the rocket’s third stage failed during the climb into space after the launch from Taiyuan. The satellites of the “Yaogan” series include satellites carrying Earth-facing optical telescopes and radar imagers to collect high-resolution imagery for the Chinese military and intelligence agencies.
On May 22, 2019 at 00:00 UTC, the PSLV-CA rocket-carrier was launched from Satish Dhawan (Sriharikota) spaceport, 80 km from Chennai, India. The rocket (PSLV - Polar Satellite Launch Vehicle) orbited RISAT-2B (Radar Imaging Satellite-2B). It is a high-power radar imaging satellite designed to peer through clouds and darkness to resolve signs of pollution, natural disasters and foreign military movements.
On May 17, 2019 at 15:49 UTC the "Chang Zheng-3C/G2” (Long March-3C/G2) rocket-carrier was launched from the Xichang Satellite Launch Center in Xichang, southwest China's Sichuan Province. The rocket orbited the “Beidou-45” navigation satellites.
On May 6, 2019 at 13:33 UTC, the private U.S. unmanned supply spacecraft, the "Dragon” SpX-17 (CRS-17 flight), was successfully docked to the International Space Station. The linkup operation was carried out with the help of the giant 17-meter Canadarm. The capture with Canadarm-2 was performed by Canadian astronaut David Saint-Jacques at 11:04 UTC. The Dragon spacecraft was maneuvered into position and attached to a berthing port on the space station's Harmony module. This docking marked the 17th time a Dragon spaceship has reached the space station, counting a demonstration flight in 2012.
On May 5, 2019 at 06:00 UTC, the “Electron” rocket-carrier was launched from Rocket Lab Launch Complex 1, the commercial spaceport located on the Mahia Peninsula on the eastern coast of New Zealand's North Island. In the frames of STP-27RD mission the rocket orbited three U.S. military-sponsored experimental satellites: Harbinger; SPARC-1 (Space Plug and Play Architecture Research CubeSat-1) and Falcon ODE (Falco Orbital Debris Experiment).
On May 4, 2019 at 06:48 UTC the "Falcon 9” rocket-carrier was launched from SLC-40 of the Cape Canaveral Air Force Station, Florida, USA. The launch was performed by the "SpaceX” private company supported by the 45th Space Wing of US Air Force. US private company SpaceX launched its "Dragon” (CRS-17 flight also known as SpX-17) unmanned spacecraft on a cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services. It is the 18th successful flight of a “Dragon” spacecraft and the 17th successful flight of a “Dragon” to the ISS.
On April 29, 2019 at 22:52 UTC (on April 30 by Beijing time) the “Long March-4” (“Changzheng-4”) rocket-carrier was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province. The rocket orbited two “Tianhui-2” satellites to conduct land surveys, mapping and scientific experiments in space.
