ESA’s first stand-alone deep-space CubeSat Henon takes shape
The European Space Agency’s upcoming Henon mission will be the first ever CubeSat to independently venture into deep space, communicate with Earth and manoeuvre to its final destination without relying on a bigger spacecraft. Once in its orbit around the Sun, the carry-on luggage-sized CubeSat will observe the Sun’s emissions to demonstrate technologies capable of providing advanced warnings of solar storms hours before they reach Earth.
