吴仪

吴 = 口 + 天 : Mnemonic symbol: the water buffalo from Wu.

Willy Walrus (w) enters the space station (Ø2) with a big mandarin (口) in his hands. The water buffalo (吴) sees it and begins to pant heavily, slightly in panic. Fortunately there is an angel (天) around to calm him down and let him know that it's not the sun he's fearing.

仪 = 义 + 亻 : Justitia (义) prepared a new apparatus (仪), an electric balance, and asks Maud Younger (y) and Rosa Luxemburg (亻) to help her test it just inside the space station's entrance (Ø2). Puzzled she finds that she is not able to weigh the two women in zero gravity.
