"Hey, I'm only four. Live and learn."


Mindy Melendez is a main character and one of Jet's best friends in Ready Jet Go!.


Mindy lives across the street and is always coming over to see what the bigger kids are doing. Mindy is 4, so she asks the real questions that 4-year-olds ask about space. The answers to these questions are often what the episodes are about. She's not always in possession of the facts and is still a magical thinker. To her, the phases of the Moon mean that there are “a lot of moons, like the round fat one, and the one shaped like a taco, and the skinny, pointy one."

There is one more neighbor who is in on the secret of the Propulsion family: Mindy Melendez. Mindy is a little girl who is the youngest member of Jet's group. Mindy, being 4, is very curious about the world around her and loves to ask questions. Due to her curiosity, Mindy is the reason for the episode events. She often asks questions that prompt the older children to go into space to find an answer. She also points things out, such as noticing that Jet's house was not on the map in Satellite Selfie.

Mindy is a little girl, so she tends to enjoy things that little girls enjoy such as dolls, teddy bears, and tea parties. She also likes to be sarcastic, self-centered, and sassy at times to the older children. In Backyard Moon Base, she buried the remote control to the Propulsion house on purpose, but she openly says that she can get away with it. "I'm only 4, live and learn." In Sounds Abound, she is practicing her flugelhorn outside, which disrupts Sean's experiment. Sean tells her that she is being too loud on her flugelhorn. Then Mindy gets upset because if Sean doesn't complete his experiment, he won't get to go to Astronaut School, and he won't become an astronaut and name a planet after Mindy. In Satellite Selfie, Mindy tells one of the kids that they can't come up with good ideas like her because "you're just not [Mindy]".

Due to being the youngest, she couldn't do as much stuff as Jet, Sean, and Sydney got to do. Her mom did not allow her to go anywhere past Jet's yard, so she had to stay on Earth while Celery took the older kids into space.  However, she does get to go trick-or-treating with everyone else in Jet's First Halloween, and she finally turns five in Mindy Turns Five, and gets to go to outer space. Mindy may not know as much as the older kids, but she’s welcomed into the group, treated as an equal, and never talked down to. Mindy also has a very close relationship with Jet’s alien pet, Sunspot, as shown in episodes like Mindy Pet-Sits

Mindy is rather plain and average compared to the other characters on the show, with Mindy not having a consistent, developed personality or purpose throughout the episodes.


Mindy has most likely already known Sean and Sydney before Jet arrived on Earth. She was probably even friends with Sean and Sydney as soon as she could walk and talk. In Mindy's Moon Bounce House, she celebrates her birthday, but it is unknown how old she turned. In So Many Moons, Mindy said that her parents are going to have a baby soon, but this particular arc was later scrapped. In The Mindysphere, she was allowed to venture farther out into the neighborhood.

In Mindy Turns Five, she turns five and gets to go to space with the older kids.


Mindy is a 4 (later 5) year old Hispanic girl with light tan skin and brown eyes. She has dark brown hair always in pigtails held by two blue hair ties. She always wears a brown crocheted bear hat with two blue buttons. She wears a crocheted orange sweater, folded denim shorts over dark grey leggings, and black flats.

Together they explore the solar system and how it affects the planet, while also learning about friendship and teamwork. The series features live-action interstitials with astronomer Dr. Amy Mainzer.
