ESA’s first mission of the year was launched 2 February 2018: GomX-4B is the Agency’s most advanced technology-tester yet, featuring a hyperspectral camera and tiny thrusters to manoeuvre thousands of kilometres from its near-twin to try out their radio link.
These CubeSats are built around standard 10x10 cm units by GomSpace in Denmark. As ‘six-unit’ CubeSats they are as big as cereal boxes – but double the size of their predecessor GomX-3, released from the International Space Station in 2015.
The pair was launched at 07:51 GMT (08:51 CET) from Jiuquan, China, piggybacking on a Long March 2D rocket carrying a Chinese satellite to detect electromagnetic disturbances that might offer early warnings of earthquakes.
