GomX-4B

This replica of ESA's GomX-4B CubeSat, produced with 3D printing, is being exhibited at ESTEC, the Agency's technical heart in Noordwijk, the Netherlands. The cereal-box sized GomX-4B – ESA’s biggest small CubeSat yet flown – has completed its mission for ESA, testing out new miniaturised technologies including: intersatellite link communication with its GomX-4A twin, a hyperspectral imager, star tracker and butane-based propulsion system.
