Hoshika tells Mutta that Houston will be able to tell if Hibito moved if he fires his remaining flare. Meanwhile, Hibito, who has less than twenty minutes of oxygen left, decides to use his last flare as a makeshift fireplace to provide Damian with some necessary heat. Hibito eventually reaches the top of the crater and exposes Damian to the sunlight, but becomes stressed when he can't communicate with anyone. Meanwhile, Houston learns of their location, which was at the point Mutta predicted, and learn that Hibito has less than ten minutes of oxygen remaining. After making sure Damian is properly shaded, Hibito decides to take a walk on his own, preparing to walk into the ravine again so he can see the stars once more. Just then, he spots the flash he saw earlier and decides to investigate it, discovering it to be a small astronaut figure left behind by Brian.
43	"Brian" Transcription: "Buraian" (Japanese: ブライアン)	February 3, 2013 (2013-02-03)[7]	TBA
Hibito reminisces about Brian, who was something of a mentor to him. Checking the back of the figure, Hibito finds a picture of a young Brian with his brother, Eddie Jay, realising Brian left the figure there so both brothers would eventually stand on the moon together. The oxygen reserves in Hibito's suit soon runs out, putting Hibito through pain as he gasps for oxygen before almost losing consciousness. Just then, the oxygen producing drone named after Brian arrives on the scene, allowing Hibito to obtain some oxygen in the very nick of time.
44	"Three Astronauts" Transcription: "San Nin no Uchū Hikōshi" (Japanese: 3人の宇宙飛行士)	February 10, 2013 (2013-02-10)[7]	TBA
It is revealed that Hibito was able to be saved because of Azuma's plea to NASA to take into account Mutta's theory as the worst-case scenario and send the Brian drone over to where he suggested. Meanwhile, Mutta is relieved to hear of Hibito's safety once news reaches JAXA. Whilst the other astronauts, Freddy Saturn and Buddy Walters, bring Hibito and Damian back to base, they reminisce about all the things Brian taught them. Three days later, Mutta gets a chance to talk with Hibito, who gives him his deepest thanks for helping to save him, promising that they'll both stand on the moon together.
45	"Five Blue Rangers" Transcription: "Go Nin no Ao Renjā" (Japanese: 5人の青レンジャー)	February 17, 2013 (2013-02-17)[7]	TBA
Mutta pays a visit to Sharon, who is shocked to hear how much danger Hibito was in. She reveals that her astronomy team has received funding to build a lunar telescope on the moon, which would allow people to see further into space, an idea spurred by her late husband, Shinichi, who named an asteroid after her before he died from an illness. This spurs on Mutta to fulfil his promise to Sharon, along with his promise to Hibito. Later, Mutta and the others receive their official JAXA jumpsuits before being informed they will be travelling to Houston tomorrow to begin their joint astronaut training.

Whilst Serika and Ena manage to find a place to live, Mutta becomes curious about something Murasaki allegedly mentioned to Kenji about the training during the flight. Deciding to ask Murasaki himself, he mentions how a few astronauts always seem to leave at some point during the training due to not being up to snuff. He goes on to explain the role of astronauts is akin to those of actors, stating he himself has never gotten the chance to 'stand on stage'. Later, the group go to the mission control center, where Mutta hears from Jennifer that Hibito probably won't be approved for any EVA operations for the duration of the mission. Afterwards, a party is held for all the trainee astronauts, where the group meet Amanti Patel from India, who has a hobby of reading people's fortunes. When asked to read Mutta's future, she has an unsteady feeling.

The astronaut candidates are briefed on their training, with Bold stating he plans to make everyone go through two years of training in a year and a half, to the surprise of his fellow instructor, Larry Bison. He starts off with the hard stuff right away by putting everyone through survival training in the desert, where they must walk all the way to Amarillo. Mutta's group, consisting of the JAXA candidates and Amanti, is led by Kenji to meet up with their advisors, Mike Davis and, to Mutta's surprise, Lowry, who provide them with lunch before informing them they'll need to forage further meals themselves.
49	"Nitta the Leader" Transcription: "Rīdā Nitta" (Japanese: リーダー新田)	March 17, 2013 (2013-03-17)[7]	TBA
As Mutta's team find their rations and set up camp for a night, they are informed they are currently last in the rankings, which requires one person beside the leader to take a punishment. Mutta volunteers for the punishment, in which he must stand at attention for a whole hour, but the group soon cheer up when they are treated to a beautiful view of the stars. Later on the fourth day, as Nitta is chosen as the leader, he appears to be a bit more strict with his desire to increase their ranking, whilst also expecting a call from a certain someone. Just then, Mutta pushes Nitta out of the way of their food crate when he notices a rattlesnake. Following the incident, Davis issues the leader with a handgun to defend themselves against dangerous wildlife. On the fifth day, as Mutta acts as leader and helps the group push onwards, Nitta suddenly tells the others that he must head back.
50	"Nitta and Mutta" Transcription: "Nitta to Mutta" (Japanese: ニッタとムッタ)	March 24, 2013 (2013-03-24)[7]	TBA
Nitta explains that he had left his phone behind somewhere, which he needs as he is expecting an important call. Nitta opts to go alone to search for it, but Mutta, being the leader, decides it would be best to search alongside him at night once they set up camp. Along the way, Nitta explains he is waiting for a call from his younger brother, Kazuya, who he hasn't spoken to in two years. Mutta suspects that Nitta may have dropped his phone near the previous food crate when Mutta tackled him, which motivates Nitta to rush to its location. Arriving at the crate, Nitta finds his phone as it flashes, only to find he had barely missed a call from Kazuya.

As Mutta and Nitta head back to camp, discussing their relationships with their respective brothers, Kazuya looks up information about the astronauts, finding a video interview with Nitta. In the video, Nitta explains how feelings that you may not belong in this world can help drive you to go beyond it, stating some of the things Kazuya taught him when they were younger. After returning to camp, Nitta explains to the others about his brother whilst Mutta once again worries about Amanti's prediction. As a starstorm flies above the desert, Kazuya starts to venture outside his own little world.

On the final day of the survival training, Mutta winds up with a fever, putting the team in a tough decision to either continue pushing onwards or retire. As leader, Amanti understands Mutta's wishes and decides that they will keep on walking, with everyone helping to carry Mutta's belongings. As the team draw close to their goal, an automated rover lands nearby, which is revealed to be part of the next task, in which they must collaborate with an engineer and develop a CanSat rover in two weeks for a Comeback Competition. As the team in last place, Mutta's team is stuck with a lazy engineer named Pico Norton, who has no intention of helping them out. As Mutta rests up from his fever, Pico goes out drinking with Vince.
56	"Promise to Drink" Transcription: "Sake no Yakusoku" (Japanese: 酒の約束)	May 4, 2013 (2013-05-04)[8]
As the news reports that Hibito will soon be returning from the moon, Pico is put under pressure as he designed the parachute that must help them land safely. After Mutta recovers from his cold, the team try to work on their project without Pico's help, being at a budget disadvantage due to ranking last. Speaking with one of Pico's co-workers, Mutta becomes more unnerved upon hearing Pico developed the parachute deployment system for Hibito's return. When Mutta brings up whether Pico's system was responsible for Brian's accident, it is explained that the head NASA engineer at the time chose another company's parachute for Brian's capsule after a human error resulted in a crash during a test of Pico's system. Hearing this, Mutta brings up to the team that they need to prepare their budget for two rovers, with the anticipation that one of them could fail.
57	"An Engineer's Switch" Transcription: "Gijutsusha no Suitchi" (Japanese: 技術者のスイッチ)	May 11, 2013 (2013-05-11)[8]
As Azuma makes his way towards the moon, Mutta's team works on testing the rover, learning of what flaws they need to fix. The team consider following another team's example and going with a glider instead of a ground rover, but Pico points out that the wind would cause issues with that plan. Using his engineer insight on how to overcome their obstacles, Mutta suggests that they make the rover's tires out of sponge, so they can have larger tires that still fit inside the rocket whilst also reducing costs and providing shock absorption. Impressed by this idea, Pico decides to give the team advice on their parachute, encouraging them to think of the rover as a spaceship containing their comrades. With Mutta's ideas and Pico's advice, the team manage to put together a working rover complete with a functioning parachute. Later, as Mutta is invited by Pico for a drink, Vince takes him for a drive.
58	"Earnest Failure" Transcription: "Honki no Shippai" (Japanese: 本気の失敗)	May 18, 2013 (2013-05-18)[8]
During their car ride, Vince mentions that he considers astronomers his enemy, due to their supposed snobbery towards manned spaceflight. When asked who his viewpoint, Mutta responds that he considers himself to be his worst enemy, with Sharon being the one who helped him see that. As Pico joins them at the bar, Mutta's remark about earnest failures reminds Pico and Vince about their childhood friend, Rick, who used to make rockets together. Back when they were fifteen, they were under pressure to give up on their dreams and settle with becoming coal miners due to the town they were raised in, but they reaffirmed their dreams after seeing Brian riding the ISS.
59	"Promise Sign" Transcription: "Chikai no Sain" (Japanese: 誓いのサイン)	May 25, 2013 (2013-05-25)[8]
Pico and Vince were pushed by their fathers and teachers to apply for their local technical college, which angered Rick, who felt betrayed by the others for giving up their dreams. Before they could make up with each other, Rick died in a car accident on the day Pico and Vince attended a career day for the mines. Distraught and angered by Rick's death, Pico and Vince reaffirmed their resolve to pursue careers as astronauts, as life is too short for unexciting things. Back in the present, Azuma and his group arrive at the moon base, where he reunites with Hibito, who thanks him for helping to save his life, whilst Mutta, Kenji and Nitta watch it on TV. As the day of the Comeback Competition arrives, Pico informs Mutta and Kenji that a rainfall the previous night could potentially cause huge problems with the sponge tires, the worst-case scenario given them only an hour to do something about it.

With a limited amount of time before they launch, the team search for materials they can use to keep the sponge tires dry. Visiting the hotel's utility room, Mutta borrows some silicone sealant from the janitor, which he uses to waterproof the tires. With all their elements in place, along with Mutta's addition of a toy astronaut to represent the purpose of the experiment, the rover manages to make it 200 m from the target goal before its battery dies, ranking them fifth overall and second amongst the AsCans. After the contest, they are approach by the winning team, whose director turns out to be none other than Naoto, who is working hard to develop a Japanese manned rocket.

Mutta, Hibito and Serika accompany Sharon to a neurologist, where Serika fears she may be suffering from amyotrophic lateral sclerosis just like her father. As Sharon is admitted for more tests, Serika explains the details of ALS to Mutta, who is shocked to learn that it may one day kill her. As such, Mutta finds himself unable to concentrate on his written test and scores terribly. Following her examinations, in which she is properly diagnosed with ALS, Sharon is visited by Serika, who tells her about her father and motivates her to work hard on her research despite her illness. As Sharon heads back towards Japan, Mutta reaffirms his promise to help build her telescope. Later, Serika tells Mutta about a similar promise she made to get up to the ISS and develop a treatment for ALS.

Deneil takes Mutta on his first T-38 flight where, unlike the other instructors, he flies at speeds of 6.5Gs. Mutta throws up on his first flight, though after hearing Hibito went through the same training, he decides to go on it again. He soon begins training to fly himself, tasked with relying on instruments instead of sight. Whilst initially having trouble, Mutta is soon encouraged by Deneil's advice and Sharon's hand written letter, encouraging him to train for what he can.
67	"Deneil-ized" Transcription: "Denīru-ka" (Japanese: デニール化)	July 27, 2013 (2013-07-27)[9]
Hibito informs Mutta that he'll be returning to Japan for a week in order to be debriefed by JAXA and visit Sharon. Meanwhile, Mutta struggles with multitasking aspect of flying a T-38, not helped by Deniel's improvisations and a burger commercial that got stuck in his head. After giving him some advice on being a top pilot, Deneil later tells Mutta that he plans to retire once Mutta becomes an official astronaut. Meanwhile, Hibito and the other astronauts go drinking with Pico, telling him about his experiences with Deneil. As Mutta finally gets the hang of his training, Deneil tells him about how he salutes to pictures of pilots and would-be astronauts who died in flight accidents.

Having finished his training, Mutta is offered a spot on the ISS backup crew; a very rare opportunity for a new astronaut. Knowing that the moon mission is his goal, he turns it down and recommends that it be offered to Serika instead. As a result, Mutta is assigned to work with an engineering team in charge of designing new lunar vehicles. He worries that this may be a dead end for his career as an astronaut, but Vince suggests that if Mutta is able to produce results, he may be rewarded with a spot on the moon mission.

Hibito and Mutta do a photo session together to appear on the cover of a Japanese magazine before Hibito departs for Russia. On the way, Hibito and Mutta discuss the failings of the lunar buggy on the Moon, leading Mutta to conclude that his team needs to take a different tack than simply improving the tires and brakes. While wearing costume spacesuits for the shoot, Mutta notices that Hibito looks uncomfortable. Unknown to him, Hibito has developed a panic disorder when wearing space suits.
72	"Hibito's Disorder" Transcription: "Hibito no Shōgai" (Japanese: 日々人の障害)	September 7, 2013 (2013-09-07)[10]
On Hibito's first return to zero-gravity training on Earth, he suffers a panic attack when lowered into the water in a space suit. Since astronauts are required to be able to perform EVAs, NASA denies him new lunar missions until he's completely recovered. Determined to do so, Hibito confides in Sharon, but asks to keep it a secret from his family and colleagues. Meanwhile, Mutta consults with Damien on how to improve the lunar buggy, and decides to leverage his old automobile industry connections for assistance.

Mutta comes up with a solution to the lunar buggy problem based on an idea he had while working at his old automobile company. He invites two junior colleagues to join him, with whom he previously developed a proposal for a flying car to solve the problem of traffic in Japan. While the project itself was considered too outlandish, the technology for projecting a route onto the windshield was put into development. With the company now committed to working for NASA, Mutta proposes a solution in which lunar surface data from JAXA's Kaguya II mission is used to project virtual roads onto the windshield of the lunar buggy, showing astronauts safe routes to drive.
74	"Magic Trick" Transcription: "Mahō no Urawaza" (Japanese: 魔法の裏技)	September 21, 2013 (2013-09-21)[10]
Chief Butler and Azuma discuss assigning Mutta to a lunar mission, and Azuma believes that Hibito would be inspired to hear of his brother beginning lunar training. However, Butler wants to be cautious—he talks about an old colleague called Ronald Cooper who developed panic disorder after a surviving a plane crash and eventually left NASA. Meanwhile, Mutta decides that he needs to impress Chief Butler—he decides to express his resolve by learning to do a vertical climb roll in his T-38, a move Butler once mentioned in an old interview as being meaningful to him, having been an Air Force pilot before becoming an astronaut. Mutta asks him to look over Ellington airport at 6:30pm as he demonstrates the stunt.
75	"My Hands" Transcription: "Watashi no Ryōte" (Japanese: わたしの両手)	September 28, 2013 (2013-09-28)[10]
Having seen Mutta's vertical climb roll, Butler stops off at the airfield. At 6:33pm Mutta wants to demonstrate a second move, for the benefit of Serika—a heart in the sky. However, the shuttle bus to the airfield is late and Serika is only able to see it side-on, mistaking it for an Alien Baltan (although Ena Kitamura realises what it is). Chief Butler sees the heart and concludes with embarrassment that Mutta has a crush on him. In Japan, Sharon misses what she used to be able do with her hands—playing piano, cutting the boys' hair, teaching them to make cookies. Daniel Morrison visits, bringing promises of help for the lunar telescope from many different collaborators, and tells her that they will be her hands. With her ability to write deteriorating, Sharon begins to verbally record instructions for building the lunar telescope.

Ivan is Hibito's mentor for his rehabilitation, and starts him out on walking a distance of 10 meters in a simple Russian pressure suit. It is enough to give Hibito flashbacks and trigger a panic attack. Hibito wants to self-isolate but Ivan insists he not be alone, inviting him for dinner with his family again. Olga notes that Hibito doesn't have the courage and energy displayed by his anime counterpart. Discouraged by his worsening condition, Hibito is in no mood to drink and leaves early, to the Tolstoys' concern.

Hibito begins training again, although Ivan refuses to show him the second part of Olga's childhood videos since Olga found out and objected to Hibito seeing them. Ivan gives Hibito a pair of sunglasses to wear, and points out that Hibito managed to successfully walk 10m in them. Gradually, Hibito progresses to more complex costumes to imitate different aspects of wearing a space suit. Back in America, however, Chief Butler is confronted by the Moonbase Program Manager Walter Gates, who reports Hibito's condition back to JAXA. It is decided that Hibito will be given the role of Safety Supervisor, taking him off active duty as an astronaut.

Ena is granted a space on the ISS backup crew as robotic arm operator, to her and Serika's delight. The NEEMO astronauts are given their primary mission: to construct a 1/3 scale model of the Moonbase, and to come up with ideas for improvements. Kenji suggests adding a long-range antenna, and Mutta has the idea of rover charging stations, thinking of Hibito's accident. He also suggests building a lunar telescope, as practice for achieving Sharon's dream. Kenji reflects on his family—Fuuka is excited that her father is training to go to the moon, but upset by his long absences. Yuki is exhausted and frustrated by raising Fuuka by herself and her difficulty speaking English. His family sacrifices a lot for him to go to space, so he is determined to do his best to get to the Moon to make their sacrifice worth it.
83	"Kenji and I" Transcription: "Ore to Kenji" (Japanese: 俺とケンジ)	November 23, 2013 (2013-11-23)[11]
George tells Mutta and Kenji that they are competing for a single spot on the Moon mission, to their horror. Mutta is driven by his promise to Sharon but Kenji, realising that he needs to stand out, reviews the model Moonbase design and determines that the antenna and lunar telescope are unnecessary additions. Mutta goes along with it, not wanting to conflict with Kenji. However, Mutta and Kenji's easy camaraderie is broken. Andy talks to Mutta about his stress and worry over not being assigned to a mission for a long time. Realising how powerless he was to affect the mission decisions from higher-ups, he decided not to think about what he couldn't control and to focus on working hard. Feeling more sure of himself, Mutta decides to make the case for keeping the lunar telescope.
84	"Supandaman" Transcription: "Sūpandaman" (Japanese: スーパンダマン)	November 30, 2013 (2013-11-30)[11]
While Mutta is enthusiastic about still building the lunar telescope, George points out that building the model Moonbase will take longer than they have time for amongst the rest of their training, and that Kenji made the right call. Unperturbed, Mutta figures out a way to save time by recruiting Andy to help him build a storage rack on the underwater rover SEV so that they can use it to transport their materials, reasoning that they wouldn't use pushcarts on the Moon anyway. Kenji thinks about 'Supandaman', a powered-up astronaut hero made up by Fuuka who can do the impossible, and is ashamed at playing devil's advocate to Mutta's ideas in order to make himself look better. Mutta tells Kenji about his conversation with Andy and his decision to focus on the present. Kenji decides to do the impossible too and stop worrying about who will be selected.
85	"On the Moon" Transcription: "Getsumen ni Ita" (Japanese: 月面にいた)	December 7, 2013 (2013-12-07)[11]
Feeling more positive, Kenji has an idea to simplify the design of the long range antenna, and suggests building Mutta's charging stations inside the habitat, saving the team more time. Mutta and Kenji's friendship and teamwork are restored as they focus on working well together again. Mutta learns that Sharon's lunar telescope proposal has been tabled due to design flaws, so Sharon can't offer advice for building the model, although she and Dr. Morrison are already working on a new design. Feeling that it is pointless to build something that's already been shot down, Mutta has a different idea for how to use the mirrors. As the NEEMO training concludes and the candidates return home, the observers discuss the training and note that while both Mutta and Kenji were excellent candidates, Mutta was the one astronaut who acted like he was already living on the Moon.
86	"For Tomorrow" Transcription: "Ashita no Tame ni" (Japanese: 明日のために)	December 14, 2013 (2013-12-14)[11]
Inspired by the low light in the habitats due to conserving energy, Mutta designs a solar mirror system to light the inside of the windowless Moonbase, in order to lift the mood of the astronauts inside the base. Impressed by Mutta's consideration of everyday life on the Moon, the observers send on the proposal for implementation in the actual Moonbase. Hibito is bored and frustrated in his safety supervisor role but his recovery is progressing, and he is recording his training for Ivan. Now able to spend forty minutes in a souvenir space suit, all he has left to master is the real pressure suit, and finally the EVA suit itself.
87	"To the Place Where I Belong" Transcription: "Jibun no Basho e" (Japanese: 自分の場所へ)	December 21, 2013 (2013-12-21)[11]
Hibito watches the second volume of Olga's dance lesson videos and learns that Olga injured her ankle badly aged eleven. She made a recovery but quit dancing for a while. But after seeing her father go to space and doing ballet moves for her in the weightlessness of the ISS, Olga rediscovers her love of dancing and, at twelve years old, returns to her lessons. Encouraged, Hibito clears the final stage of his rehabilitation, wearing a pressure suit, and asks Chief Butler to give him a chance to prove himself capable of being an astronaut again. Mutta returns to Houston from Florida.
88	"Pretty Dog" Transcription: "Puriti Doggu" (Japanese: プリティ・ドッグ)	January 4, 2014 (2014-01-04)[11]
Hibito meets Azuma when visiting Brian Jay's grave on the anniversary of his death. Reflecting on how Brian was like an older brother to both of them, Azuma encourages Hibito to confide in his real living brother. While in a taxi, Hibito has a nightmare and panic attack, and has to get out of the car. He asks Mutta to meet him at a bar, and confesses to having a panic disorder—Mutta initially mistakes the abbreviation 'P.D.' as short for the title of a cartoon, Pretty Dog, but upon realising what Hibito means, reassures him that he is capable of passing the test. He notes that the fact that Hibito had a panic attack in the taxi means that it is not specifically the spacesuit that causes the attacks, and that Hibito can trust it. And, if he should feel a panic attack coming, that he can use the initials P.D. to remind himself of his dog instead.
89	"Last Words" Transcription: "Saigo no Kotoba" (Japanese: 最後の言葉)	January 11, 2014 (2014-01-11)[11]
Mutta is assigned as Vincent Bold's backup for the next lunar mission, cementing him on a journey to the Moon. He is very tired on his first day, having stayed up late the previous night researching Hibito's disorder after their conversation. Kenji and Nitta, meanwhile, are assigned to zero-gravity training. While they are not yet given any details of a mission, Chief Butler assures them that they will understand why once assigned to a mission. Lowry and Dr. Olivia prep Hibito for his test to go back to active duty.
90	"A Small Note and a Big Lucky Charm" Transcription: "Chitchai Memo to Dekkai O Mamori" (Japanese: 小っちゃいメモとでっかいお守り)	January 18, 2014 (2014-01-18)[11]
On the day of his test, Mutta sends Hibito a novelty Pretty Dog double mirror as a lucky charm, having read that looking at oneself objectively can help with panic disorders. Hibito wears it strapped to his spacesuit arm as he descends into the water. While underwater, Hibito proceeds through a simulated mission without a panic attack. Part way through, Butler triggers a green card to test his reasponse to an accident. Hibito receives an alert that his CO2 level is rising and copes well with the situation. Sceptical of Hibito's suitability, Gates triggers a second green card without telling Butler. Hibito receives an alert for a CO2 sensor malfunction and his heart rate rises, but with the help of Mutta's advice he manages to stave off a panic attack. A second run of short Mr. Hibbit episodes airs after the credits of some episodes from this episode onwards.
91	"How to Help Hibito" Transcription: "Hibito no Sukuikata" (Japanese: ヒビトの救い方)	January 25, 2014 (2014-01-25)[12]
The second green card causes Hibito's test to be extended as he heads into the airlock to reset his suit. Having heard about Hibito's test from Mutta, Hibito's old crew arrives to support him—Buddy and Linda take over communications, and Damian joins in on the EVA. Butler approves it, since in reality Hibito will always have the support of crewmates and an EVA partner. He also doesn't simply want to test Hibito, but to help him recover in the way Ronald couldn't. Working with his old crewmates reminds him of his happiest times on the Moon, and Hibito begins to enjoy himself again. After his own training, Mutta runs over to the pool in time to see his brother being congratulated by his colleagues on successfully passing his test.
92	"Lonely People" Transcription: "Kodoku na Karera" (Japanese: 孤独な彼ら)	February 1, 2014 (2014-02-01)[12]
Mutta meets the rest of the lunar backup crew, made up of his NEEMO crewmate Andy, along with Phillip Louis, Carlo Greco, and Betty Rainer. They begin Desert RATS training, at a simulation habitat in the north Arizona desert, alongside the prime crew. As they are introduced to the Beetle vehicle and lunar spacesuits, Mutta notices that the crew is dysfunctional and argumentative. Back in Houston, Butler explains that the crew is made up of misfits that other astronauts were reluctant to work with. Unbeknownst to him, Mutta has been assigned to the crew as a gamble to bring them together, alongside the candidate for a crew captain.
93	"In the Corner of My Heart" Transcription: "Kokoro no Katasumi ni" (Japanese: 心の片隅に)	February 8, 2014 (2014-02-08)[12]
Sharon and Daniel Morrison arrive in Houston to present a new proposal for the telescope—one much easier to construct and more robust than an optical telescope. With established interest from Mutta to undertake the construction, the proposal is given serious consideration. While Sharon is in Houston, Hibito lets her know that he is recovered and simply waiting to be assigned a mission. Chief Butler approaches Brian Jay's older brother, Eddie Jay, hoping to recruit him as the backup lunar crew's captain. While highly experienced with ISS missions, Eddie is reluctant to start from scratch with lunar training, believing himself to be too old to start something new. Butler gives him photographs of the astronaut figure that Brian left on the Moon, found by Hibito. Reminded of Brian's faith in him that he'd get his chance to go to the moon, Eddie accepts the position of captain.
94	"Exciting Teamwork" Transcription: "Waku Waku Chīmuwāku" (Japanese: ワクワクチームワーク)	February 15, 2014 (2014-02-15)[12]
As Desert RATS training proceeds, Mutta notices that the crew is disorganised, with each member operating independently, such as doing their morning run at their own paces. Mutta attempts to unify the group, but as the newest astronaut among them, none are inclined to follow his lead. Eddie Jay arrives to lead the team, and he and Mutta quickly develop a rapport. Learning the various peculiarities of the crewmembers, Eddie begins to change up their routine to encourage them to work together.
95	"Our Future" Transcription: "Orera no Shōrai" (Japanese: 俺らの将来)	February 22, 2014 (2014-02-22)[12]
Betty Rainer shares about her son, Chris. Betty was married to Tuck Ravel, one of the astronauts who died in the accident that also killed Brian Jay. When Chris was born, she temporarily left the astronaut corps to raise him, but after the accident she didn't think she would go back, until Chris began to take interest in space again. While everyone else objected, she signed back up with the blessing of her son. The last stage of Desert RATS begins, in which the main and backup crews will work together. Mutta meets Pico again, who has arrived to introduce the new lunar landing module with an addition called the STITCH—a vehicle with wheeled legs that can transport the various parts of the landing module around, allowing them to keep the Moon landing area clear. Amused at the make-up of the backup crew, he nicknames them the 'Jokers'.
96	"Astronaut and Father" Transcription: "Uchū Hikōshi de Ari Chichi de Ari" (Japanese: 宇宙飛行士であり父であり)	March 1, 2014 (2014-03-01)[12]
Kenji and Nitta continue their training, despite having no clear objective. With the long hours keeping him away from his family a lot, Kenji feels like he isn't doing a good job of being either an astronaut or a father. A Christmas barndance is held in Houston—Mutta goes dancing with Serika and Ena, Hibito plays guitar in the band, and while Kenji and Nitta sit out the festivities due to being so busy, Chief Butler takes them aside and tells them that they have been assigned to a mission—the first crewed mission to an asteroid. Soon after, Kenji and Yuki's second daughter is born and they name her An, from a suggestion from Fuuka and the name of the asteroid that Kenji will visit.
97	"Won't Go Away" Transcription: "Kienainda" (Japanese: 消えないんだ)	March 8, 2014 (2014-03-08)[12]
Mutta and Hibito's parents visit for New Year, and Hibito confides in Mutta that he's not sure that he'll be able to return to the Moon, having not yet been assigned to a new mission. Despite his recovery, his reputation has been damaged. Serika and Mutta begin CAPCOM training for their respective missions, to Mutta's delight. Chief Butler tries to persuade Walter Gates to assign Hibito to a new mission, but Gates believes him to be too risky a choice. Distaught to have failed him, Butler breaks the news to Hibito, who is unsurprised to discover it. Without telling anyone, Hibito leaves Houston and disappears.
98	"The Ultimate Astronaut" Transcription: "Saikyō no Uchū Hikōshi" (Japanese: 最強の宇宙飛行士)	March 15, 2014 (2014-03-15)[12]
Mutta is not doing well in CAPCOM training—he and Vince are not gelling well, and he is struggling to keep focussed in the days since Hibito's disappearance. Hibito hasn't contacted anyone and is not replying to messages. Worried that he hasn't shown up at work, Butler calls Mutta about his brother. He tells him about a petition to reinstate Hibito from a number of senior astronauts, which was not enough to change Gates' mind, and warns Mutta from trying to interfere and risking his own position. Worried and distracted, Mutta makes a serious error in CAPCOM communication. The final Mr. Hibbit episode airs after the credits.
99	"Life Changes, Promises Don't" Transcription: "Jinsei Kahen, Yakusoku Fuhen" (Japanese: 人生可変、約束不変)	March 22, 2014 (2014-03-22)[12]
Pico overhears Vincent dressing down Mutta for his failure. Vince wants Mutta to be on the same wavelength as him, and Pico points out that they have things in common, suggesting that they talk to each other outside of training. Nitta tells Mutta that his younger brother Kazuya has started going outside, and has applied for a space industry job. While he was overidden due to his previously being a shut-in, instead he's learning English and planning to join Nitta in Houston. Mutta gets a message from Hibito. He has decided to leave NASA, but is not giving up on being an astronaut. Butler and Hoshika meet up to discuss Hibito's next step—going to Russia to train as a cosmonaut. Vince introduces Mutta to his family, and Mutta begins to figure him out. Six months later, with Mutta as CAPCOM, Vince and his crew successfully launch, bound for the Moon.
