There is a planned launch this month of a Chinese Long March 2D rocket from Jiuquan Satellite Launch Center, China. The Gaofen-6 remote sensing satellite will join the country's primary civilian Earth Observation
infrastructure comprising a variety of differently-instrumented satellites operating from different orbits to capture a comprehensive set of land, ocean and atmospheric parameters. It carries a package of three cameras, one for black-and-white imaging at a
two-meter ground resolution, one for colour imaging at eight-meter resolution and one for wide-angle colour imaging at a 16-meter GSD. It is intended as a replacement for the first Gaofen satellite launched in 2013.

Facts: Yuri Gagarin (b.1934) became the first man in space in April 1961. He entered into an apprenticeship at the age of 16 as a foundryman at the Lyubertsy Steel Plant near Moscow. After graduating
from both the seventh grade and vocational school with honours in moldmaking and foundry work, he was selected for further training at the Saratov Industrial Technical School, where he studied tractors. At a local flying club in Saratov he learned to fly a
biplane and a Yak-18 trainer.

News Extra: Anne McClain (b.1979) was born and raised in Spokane, Washington. She graduated from the United States Military Academy, where she earned a bachelor,s degree in mechanical engineering.
McClain then came to England where she attended the University of Bath where she earned a master's degree in aerospace engineering, and the University of Bristol where she earned a master's degree in international security. McClain is also an avid rugby player
and plays at a competitive level. Her army commitments thwarted her international career and prevented her participation in the 2006 Women's Rugby World Cup. In June 2013 she was selected by NASA as part of Astronaut Group 21, becoming the youngest astronaut
on the NASA roster.

David Saint-Jacques (b.1970) was born and raised in Quebec. He is married and has three children. He began his career as a biomedical engineer at the Quebec firm Electromed. His studies also included
theoretical work on astronomical observation and design, fabrication and commissioning of instruments for the Cambridge Optical Aperture Synthesis Telescope and for the William Herschel Telescope in the Canary Islands. He was selected in May 2009 by the Canadian
Space Agency.

Oleg Kononenko (b.1964) is married and have
a son and daughter. In March 1996 he was selected as a cosmonaut candidate. His first mission to the ISS was as a flight engineer that was launched in April 2008. In his previous three missions to the ISS he has spent a total of 533 days in space.
