* ShowWithinAShow: ''Ganbarion''[=/=]Galaxy Blast, a mecha anime Matataki likes, which the girls exploit to try and win her over. It seems to be based on ''Anime/TengenToppaGurrenLagann''; aside from ''Ganbarion'' sounding like ''Gurren Lagann'', the poster shows a character wearing goggles on his head like Simon, and Matataki shouts out that her rocket will "pierce the heavens!" when she competes with the other girls.

* IdiotBall: The girls want to figure out the mystery of Yuu's origins, yet -- as of the end of volume 4 -- it hasn't crossed their minds to do any investigation whatsoever into who's been selling the alleged Cosmic Language dictionary on the internet? Not even trying to find out who the publisher is or anything? Matataki even brings this point up in chapter 36, but she doesn't follow through on it (or, if she did, she neglects to share what she learned with the others/the readers) [[spoiler: until a potential answer is just dumped in their laps in chapter 43.]]

* EveryoneKnowsMorseCode: Well, ''wabun'' code (the Japanese form of morse code). In the Anime opening, the wabun code for the words "teya　seyo (てや　せよ)" repeat 10 times, becoming the backing rhythm of the opening. It translates to either "Let's do it!" or "Give Me a hand."

** When Matataki unveils her second bottle rocket at the duel in Chapter 10, she points out the rules didn't forbid using gunpowder as an accelerant.
** When the duel is adopted in episode 4, Raimon confirms that the rules require a ''bottle'' rocket. When Umika's water rocket outperforms hers on the second round, Raimon breaks out a black powder rocket fit into a small plastic bottle that technically qualifies.

** When Matataki unveils her second bottle rocket at the duel in Chapter 4, she points out the rules didn't forbid using gunpowder as an accelerant.

* LoopholeAbuse: When Matataki unveils her second bottle rocket at the duel, she points out the rules didn't forbid using gunpowder as an accelerant.

* LowerDeckEpisode: The volume 4 ''omake'' is about Emihara-sensei by herself, taking the test to get her model rocket license.

* FakeCameraEffects: The author puts in the effort to blur the foreground or background to emulate DepthOfField, such as in chapter 38 when Umika comforts Yuu and her phone rings.

* FirstContact: {{Discussed|Trope}} in chapter 40. [[spoiler: When the girls make contact with an alleged alien over the radio, Matataki says it's the club's first contact. Then she elbows Yuu and corrects herself, saying it's really their second contact.]]

* AdvertisedExtra: The anime promotional materials hyped up Honomi like she's a main character, even though she only appears in a handful of scenes and has a negligable impact on the plot, whereas Kei Akizuki (a far more important character) got no promotion whatsoever and didn't even have her voice actress revealed until the credits of her debut episode.

* CentralTheme: The relationship between a character's dreams, and their identity and sense of self.
** Umika's dream is to leave Earth, as a manifestation of her alienation from others. In middle school, Matataki barked at her, "Don't talk to me if you've got nothing to say," which seems to have been the trigger for Umika's {{Elective Mut|e}}ism. In feeling like she had nothing to say, she effectively denied herself an identity and withdrew from humanity. But her dream eventually leads her to found the Rocket Research Association. With the help of her friends (and rivals), she slowly rebuilds an identity for herself as the president of the RRA and regains the ability to speak to others.
** Yuu has no past, so she doesn't know how much of her schtick as a quirky "good" alien is a lie -- which is represented by the recurring motif of television static. Her ignorance of her past leads her to some very dark places as she starts to believe her true identity is that of a "bad alien". Her dream of uncovering her origins becomes a desperation to settle the mystery of her past in a way that doesn't affect her relationship with Umika.
** Haruno was emotionally wounded as a girl by her own dreams and her friendships falling apart, so (with her grandfather's encouragement) she created a new identity for herself as a selfless TeamMom who helps everybody else achieve their dreams. But she comes to realize that attitude is wrong and resolves to find an identity and a dream for herself while still helping the RRA, declaring in chapter 30, "So, if there's something I can do, I want to give it my all. And through that, little by little, I'd like to find something only I can do."
** Matataki copied her identity from the protagonist of the ''Ganbarion'' anime. This isolated her from her peers, who thought she was too 'boyish' to get along with and would rather talk about dramas instead. Rather than change herself to become more girly, Matataki doubled down on her ''otaku'' identity and withdrew from society, making her dream into building ''Ganbarion''-style robots. But once Umika seeks her out and expresses approval of her identity by [[spoiler: complimenting the goggles she wears]], Matataki (very, very slowly) comes to accept the RRA as a place where her ''otaku'' nature will be appreciated.

* FamilyThemeNaming: Umika's mother works in an aquarium, and she gave both of her daughters names with sea-related kanji: the "umi" in Umika means "sea" while "nami" in "Honami" means "wave."

* DepthOfField: The author puts in the effort to blur the foreground or background to emulate depth of field, such as in chapter 38 when Umika comforts Yuu and her phone rings.

* LinkedListClueMethodology: [[spoiler: The girls investigate the lighthouse to find a radio, which lets them talk to somebody claiming to be an alien, whose signal dies and leaves them with a set of numbers they have to decipher.]]

** At the steart of the duel Raimon confirms that the rules require a "bottle" rocket. When Umika's water rocket outperforms hers on the second round, Raimon breaks out a black powder rocket fit into a small plastic bottle that technically qualifies.

* ExactWords: At the end of chapter 20, on the eve of the championship qualifiers, Umika declares, "With all our efforts, our rocket will fly into the heavens!" [[spoiler: Unfortunately, the qualifiers test how well you can get a model rocket into the target zone. Their rocket overshoots the target by a huge margin, flying "into the heavens" but instantly disqualifying them from the championship.]]

** A pseudo-IdolGenre story where the characters angst about their psychological scars holding them back and have emotionally-volatile, teary-eyed interpersonal conflicts that wouldn't be out of place on ''Franchise/LoveLive''.

* AdvertisedExtra: The anime promotional materials hype up Honomi like she's a main character, even though in the manga, during the first two volumes (the average length of an adaptation), she only appeared in about three scenes, max.
