PARIS (ESA PR) — The traditional curved antenna reflector is instantly recognisable on a satellite, but also represents one of the bulkiest elements aboard. As an alternative, new ESA-backed software allows antenna designers to achieve comparable radio frequency performance from flatter, smarter ‘reflectarrays’, which can be manufactured cheaply, just like printed circuits. Two forthcoming ESA missions will demonstrate reflectarray antennas, one in Earth orbit and the other into deep space.
PARIS (ESA PR) — This replica model of ESA’s ‘Miniaturised Asteroid Remote Geophysical Observer’, or M-Argo, was on display at the Agency’s recent Antennas workshop. It is the one of numerous small missions planned as part of in ESA’s Technology Strategy, being presented at this month’s Space19+ Council at Ministerial Level.
PARIS, 23 May 2019 (ESA PR) — ESA has just signed a contract with GomSpace Luxembourg to design the first ever nanosatellite to rendezvous with an asteroid.
The Miniaturised Asteroid Remote Geophysical Observer (M-ARGO) mission will be a standalone spacecraft, meaning it will have all of the fuel, propulsion systems and thrusters to complete its journey on board. In comparison to another ESA nanosatellite to be flying in deep space, HERA, which will piggyback on another spacecraft.
PARIS (ESA PR) — M-Argo is designed as ESA’s first CubeSat to enter interplanetary space.
Studied in the Concurrent Design Facility, ESA’s highly networked facility for designing novel missions, the ‘Miniaturised Asteroid Remote Geophysical Observer’, or M-Argo, is a nanospacecraft based on the CubeSat design employing standardised 10 cm cubic units within which electronic boards can be stacked and subsystems attached.
