Tonight the #NCLE radio astronomy antenna onboard #Change4 #moon relay satellite #Queqiao was fully switched on. All systems work. Antennas still stowed. We will perform first calibration measurements now. Congratulations @MarcWolt and team @RadRadioLab @isis_space @ASTRON_NL pic.twitter.com/yIQzmcaoEk
