This tore electrons out of the xenon atoms, i.e., it ionized them. Very shortly afterward, the physicists fired a second pair of short laser pulses at the electrons released in this way ...

Both missions were important technical demonstrations for the further development of electrical space propulsion systems. In an ion propulsion system, electrons are fired into a magnetic field ...
