1975-10-02 - Utahime-06, the final mission of the Utahime program (Pilot: Akari Miura) 1975-10-31 - Akatsuki-2 in Venusian orbit

Phase 2 - 22 1975-10-02 - Utahime-06, piloted by Akari Miura, was the final mission in the Utahime program. After docking with the third Rendezvous Test Vehicle 300 kilometers above Earth, Miura waited for almost a day before using the RTV's propulsion system to raise the apoapsis to 1039 kilometers where she could view most of Hatsunia. Then she returned to a 300 x 300 kilometer orbit before undocking and performing the last re-entry and splashdown of an Utahime capsule, which would be replaced in a few years by a newer, bigger crew vehicle that was being developed along with its launch vehicle. 1975-10-31 - Akatsuki-2 performed Venus orbit insertion, which mostly took place while Venus was blocking communications signals to and from Earth. The final orbit had a periapsis of 539 kilometers and an apoapsis of over 9000 kilometers. The spacecraft observed the thick, dense, and hot CO2 atmosphere and its cloud layers in visible, infrared, and ultraviolet spectra, while mapping the topography of the terrain and measuring the ionosphere and magnetic field around Venus. The orbiter discovered an equatorial jet stream, and a large atmospheric wave in the region of Aphrodite Terra nearly stretching from pole-to-pole. 1976-07-19 - Usagi-9, HASDA's second lunar lander probe, went to Ina, a shallow crater in Lacus Felicitatis (Lake of Happiness) considered to be one of the Moon's lowland regions. The surface was porous from ancient volcanic activity, with high levels of titanium.

Episode 46 (third-party revival) has now been released!

@Capital_Asterisk I used your techniques in this video (launch and re-entry only). Thank you!

Hatsunese Space Program - Rockets 1952-1972 1952-1960: Negi-1 and Negi-2 sounding rockets (similar to Aerobee and Viking) 1960: Negi-2B orbital rocket (similar to Vanguard, but pretend it has better reliability) 1962: M-1 rocket (similar to Thor-Ablestar) 1967: M-1A rocket (Thor-Delta Heavy) 1970: M-1A crew version (Utahime) 1972: M-1B rocket (Thor-Centaur Heavy, but with non-balloon tanks)

1975-07-02 - Launch of the Watarimono probe using an M-1B rocket with a Star-39H upper stage. It would visit Jupiter in 1977 and Saturn in 1981.

Phase 2 - 21 The development of HASDA's mass and volume-constrained interplanetary probes was becoming part of the revolution that was making computers smaller and more convenient for public use. Computers across the country were also starting to be connected in what was known as the "Hatsu-net" project, started earlier in the decade for use by universities and the military. 1975-01-07 - Mio arrived at Mercury, but was only within the sphere of influence for four hours. It observed Mercury's craters and escarpments (cliffs formed at fault lines, suggesting geological activity in the distant past), a trace atmosphere of helium, a magnetic field implying a large iron core, and large temperature variations between the night and day sides (-183 °C to 187 °C). It also measured the plasma of the solar wind at a much closer distance compared to Earth. Small course corrections put it on a path to visit Mercury again in approximately six months (2 Mercurian years), but due to Mercury's 3:2 spin-orbit resonance (3 rotations for 2 orbits around the Sun), only the same portions of the surface would be visible. Data from Mio complemented NASA's Mariner 10 probe, mapping some parts of the planet that were in shadow when it passed by Mercury. 1975-06-08 - Akatsuki-2 (PLANET-E) was launched to Venus, where it would perform an orbital insertion at the end of October to study the Venusian atmosphere at different wavelengths. Shaped as a rectangular prism with two solar arrays, it contained metal balancing plates etched with images of Hatsune Miku (like all Hatsunese probes) and thousands of submissions from the public for a "Send Your Name to Venus" campaign. (real life inspiration: http://wiki.nicotech.jp/nico_tech/index.php?HatsuneMiku_to_Venus) 1975-07-02 - Mio made its second flyby of Mercury, passing closer to the southern hemisphere. 1975-07-02 - Watarimono (渡り者, "wanderer") or PLANET-F was launched as Hatsunia's first probe to the outer planets, specifically Jupiter and Saturn, using a design similar to Pioneer 10 and 11. After using the Hakuba hydrolox stage, the spacecraft was boosted by a Star-39H solid kick motor borrowed from Thiokol, as it had a high propellant mass fraction in a small, compact package. It provided the majority of the 6390 m/s required to get to Jupiter, where it would be redirected to Saturn by its gravitational field. Because solar panel power generation is too weak at those distances, two SNAP-19 radioisotope thermoelectric generators (RTGs) were used. The Plutonium-238 fuel in the RTGs was expensive to produce, and used a significant but not excessive portion of HASDA's budget, but provided higher power density and safety compared to alternatives. This mission was done in preparation for a Grand Tour of Jupiter, Uranus, and Neptune which would occur in the late 1970s with a larger next-generation rocket. Watarimono was expected to reach Jupiter in December 1977, and Saturn in May 1981 with a flyby of its atmospheric moon Titan. (a closer flyby of Saturn was prioritized instead)

1975-01-07 - Mio flies by Mercury 1975-06-08 - Akatsuki-2 is launched to Venus

Keep in mind that my pacing is deliberately slowed down somewhat, and required me to cheat for science points in the 1960s because the tech tree assumes you're going everywhere as soon as possible. And HASDA will definitely pick up the pace in the coming decades. (If you want to see where all of this will lead to in the 21st century, the wiki is an open book. Keep in mind that the images are placeholders.)

They're going to leap from a single-person tech demo capsule to a three-person capsule.

1974-10-14 - Usagi-8 lands on the Moon (Mare Humorum)

Phase 2 - 20 1974-08-24 - Mio got a gravity assist at Venus on its way to Mercury, passing as close as 600 kilometers from the planet. 1974-10-10 - M-1B launched Usagi-8, Hatsunia's first (robotic) lunar lander, which arrived on October 14. The design of the lander was an adaptation of the Usagi-6 and 7 orbiters, with larger propellant tanks to be able to decelerate into lunar orbit and land on the surface, extendable leg structures to support the vehicle once landed, and solar panels angled to receive some light when the Sun is low in the sky. The landing site was a relatively flat area in Mare Humorum (Sea of Moisture), a basaltic plain which has been estimated to be 3.9 billion years old. Data about local magnetic fields, high-resolution images of the surrounding area, and regolith composition were transmitted. The probe's systems had to hibernate during the half-month-long lunar night.

They finally finished Star Boom 3, the first interstellar colonization mission (imgur gallery) I will again repost it here under the spoilers if you can't load the imgur gallery.

1974-06-18 - HASDA's first docking (using smoothing techniques by @Capital_Asterisk)

1974-06-18 (06-19) - Utahime-05 docked to Rendezvous Target Vehicle-2 (video)

Phase 2 - 19 1974-03-13 - The Mercury flyby probe "Mio" (PLANET-D) was launched by an M-1B. The name, meaning "waterway," represented the journey it would take through interplanetary space and the solar wind, as it would conduct the first gravitational assist at Venus en route to Mercury. This would save propellant and Delta-v requirements by transferring some of Venus's orbital energy to change the spacecraft's velocity. The name also reflected the Chinese and Japanese names for Mercury, which meant "water star" (水星) as it represented one of the five elements in Chinese philosophy. The probe was due to arrive at Mercury in January 1975. 1974-06-18 - Utahime-05 was piloted by Marumi Nabatame to conduct the first orbital docking with the second Rendezvous Target Vehicle. This required the attachment of a small docking port at the end of the cylindrical structure that normally detached when the launch escape system was jettisoned. The procedure for carefully approaching the target, moving into position, and docking was partially assisted by computers to compensate for limited visibility from the capsule. Once docked, Nabatame performed an EVA to test satellite inspection and repair operations. Afterwards, she undocked from the RTV and returned to Earth about a day after launch.

1974-02-28 - Nozomi-2 orbits Mars

Phase 2 - 18 1973-01-04 to 1973-10-22 - Sakura-5a, 5b, 5c, and 5d were launched by M-1B rockets and their "Hakuba" hydrolox upper stages to form a new geostationary communications network spanning most of the globe. Advances in antennas made longer-range applications of communications satellites possible. The network was used to maintain almost-constant connections for future satellites launched into Earth orbit. It was also used for communications between places on Earth during emergencies, or to remote areas. Sakura-5a was positioned over Hatsunia and the western Pacific Ocean, 5b over the Middle East, 5c over the Atlantic Ocean, and 5d over the eastern Pacific Ocean. Sakura-5a (5b, 5c, and 5d) 1973-04-01 to 1973-04-08 - Utahime-04, Yuzuki Morita's second flight, was launched by a triple-core M-1A to perform the first crewed rendezvous. The reason why leading zeroes were used for human missions was that the number "4" could be pronounced similarly to the word for "death" (shi) in Hatsunese* (an alternate pronunciation for 4 was yon). The destination was the Rendezvous Target Vehicle (RTV-1) which had launched a week earlier by a single-core M-1A to a 300 kilometer orbit. It only consisted of the M-1A upper stage and a basic cylindrical structure with solar panels to keep the batteries alive. Utahime-04 launched into a 200 kilometer orbit and was behind the RTV, but since a lower orbit is faster, the capsule gradually caught up. It performed a transfer burn to intercept the RTV, then another burn to slow down relative to the target. Morita was assisted by radar systems and some visual aids to maneuver the capsule in front of the RTV and proceed forward as if to dock, stopping only a few meters short, then backing away. After station-keeping for about an hour, she initiated the Earth return sequence and splashed down almost 21 hours after launch. [*supposedly this is why the video game "Ace Combat 04" is specifically named that way, at least according to TV Tropes] (pretend that the capsule has forward-facing windows) 1973-08-05 to 1974-02-28 - Nozomi-2 or PLANET-C was HASDA's first Mars orbiter, launched by an M-1B rocket on a seven month journey. On 1974-02-28, the spacecraft arrived at Mars and inserted itself into a 300 by 3400 km polar orbit. It built an extensive map of the Red Planet as it observed craters, deep valleys, inactive volcanoes, polar ice caps made of frozen water and carbon dioxide, and dust storms. Implications of past liquid water were seen in what looked like dried out rivers and lakebeds. The upper atmosphere, ionosphere, and the magnetic and gravitational fields of Mars were also studied.

Phase 2 - 17 1972-04-17 - "Taiyou" was a spacecraft launched by a single-core M-1B to study the Sun's effects on the Earth's upper atmosphere (using an ultraviolet spectrometer), magnetic field, and plasma environment. It also tested a heavier and more sophisticated live camera. 1972-08-09 - Utahime-03, piloted by Akari Miura, tested the endurance capabilities of the spacecraft's life support systems. She spent over three days in orbit photographing the stars and Earth and recording her medical status, as the alkaline fuel cells produced power from the reserves of liquid hydrogen and oxygen, generating water in the process. Due to the small space of the capsule, a person could not psychologically handle being in there for longer periods of time. 1972-11-21 - M-1A launched Usagi-7, Hatsunia's second lunar orbiter. The probe had higher-resolution instruments compared to its predecessor, a slightly longer structure to hold these instruments, and spherical propellant tanks. It used the camera to select sites for future lunar lander probes.

How was the audio synchronized? (I'm guessing it's tedious)

(Hatsunese Space Program - Phase 2 - 16) 1972-01-09 - The M-1B rocket launches with a high-energy liquid hydrogen/oxygen upper stage Hatsunese Rockets 1952-1972

Phase 2 - 16 The M-1B launch vehicle replaced the hypergolic upper stages of the M-1A with the first Hatsunese cryogenic stage, which used the LE-05 engine fueled with liquid oxygen and hydrogen. The higher specific impulse (444 s vs 311 s) of the LE-05 meant that the payload capacity could be approximately doubled from 2800 to 4800 kg to low Earth orbit. Without boosters, up to 1900 kg could be launched. Only two stages were needed to send most payloads destined for geostationary transfer orbit and beyond, so the shorter version of the M-1A fairing could be used. The second stage was also longer due to hydrogen's low density, but was still light enough to be lifted by a single LE-04 core stage. The development and operation of such an engine and its associated infrastructure had significant costs, due to the very low temperatures of liquid hydrogen which made it difficult to store, but they were considered worth it for launching larger or longer-range interplanetary probes without completely redesigning the rest of the vehicle. Insulation and white paint were used to mitigate the evaporation and leakage of hydrogen when in orbit. edit: the hydrolox upper stage was nicknamed "Hakuba" (白馬) or "White Horse." 1972-01-09 - The M-1B launched the Neginohana-3 test satellite to geostationary orbit. The LE-05 ignited at almost 100 kilometers, with a flame that was faint but packed a lot of energy. It burned again to deliver the satellite to a geostationary transfer orbit. After separation, Neginohana-3 used two burns: the first burn to raise its orbit slightly so that by the next time it reached apogee, it was above East Asia and Australia.
