With the arrival of second daughter Penny, Maureen Robinson left her job at Tetrodyne Chemicals and became a full-time housewife, "a position she found fully satisfying."
Like all the Robinson children, Penny was talented and intelligent. By the time of the Jupiter 2 launch, when she was 12 years old, she had advanced to the 10th grade and had an I.Q. of 147.
Shortly after the Robinsons moved from California to Houston, Texas, for their flight training at the United States Space Corps Training Center, Penny joined the newly formed Space Scouts. This was a program that Alpha Control had set up to recruit young people for future colonization missions. Penny's "leadership abilities were proven" when she was soon elected president of the Houston chapter.
Penny has some "tom-boyish" characteristics, probably due to her closeness to her brother, Will. She also has a tendency to let her imagination run out of control. Her parents sometimes have difficulty telling when she's being factual and when she's indulging in fantasy. This got her into some trouble during her year on Priplanus.
"Another aspect of Penny's character is her outgoing, friendly personality, which made her very popular with Alpha Control instructors and employees."
As Alpha Control's psychological tests predicted, Penny adjusted very well to the stresses and pressures of space travel.
