Hatsunese Space Program - HASDA (RSS/RO) | 1963-03-20 | Founding of HASDA and Negi-F sounding rocket launches

Recommended Posts

Hatsunia is a country that exists in a parallel universe in the place of Japan. It became a democratic constitutional monarchy in 1868. In the late 19th century, the Micronesian islands were purchased from Spain, being called Mikuroneshia (pronounced with a mee-, not my-) in Hatsunese. This would be the only territorial acquisition by Hatsunia; no annexation of Korea, Taiwan, or anything else. Instead of becoming a militarist and ultranationalist empire, Hatsunia stayed a democracy and joined the Allies during WWII.

In the early 1950s, a facility for testing sounding rockets and missiles was built on the island of Negishima (3.9°N, 139°E) in the autonomous prefecture of Parao. It was coincidentally shaped like a green onion.

(imaginary island made by editing EarthHeight.dds and EarthSurface.dds)

This location was selected because a proposal for the site on the mainland brought concerns from the fishing industry that rocket launches could disrupt harvests, resulting in a limited period for launching rockets (190 days a year). It was also selected for the potential of orbital launches due to the faster rotation of the Earth near the equator.

Sounding rockets would be tested by the Rocket Development Promotion Headquarters of the Hatsunia Science and Technology Agency in cooperation with the Institute of Industrial Science at the University of Miraito. In 1962, this division would eventually become the Hatsunia Aerospace Science and Development Agency, or HASDA. Hidemi Utagawa was a key figure in the development of Hatsunese rocketry.

I'm loving this, @Pipcard! I'm making a Career mission report myself, and I just want to say, this is really well done!

List of Negi-A launches from 1956-08-31 to 1957-07-09:

K2teBGg.png

SRP (Sounding Rocket Payload) expressed in liters; each SRP is 0.5 kilograms. All Negi-A rockets carried a thermometer, barometer, and telemetry equipment.

[With Kerbal Construction Time at the minimum build rate, each rocket takes only 8-9 days to build, but Japan did not launch sounding rockets over 40 times a year, so I assumed 39 days between launches. Also, range safety (self-destruct) is activated after the rocket reaches its target altitude for contract gameplay purposes; the apogee is the altitude above Earth it would have reached.]

Notable launches:

Negi-A-08 had a record-setting 173 kg of payload carried to 100 km.

Negi-A-09 would be the last flight of this sounding rocket. Carrying 75 kg of payload to 200 km pushed the Negi-A to its limits. A new kind of rocket was being prepared for the International Geophysical Year.

Notable launches:

(edit: moved captions above images)

Spoiler

All launches of the Negi-B had a decoupler and parachutes for the payload. Each modular payload container could hold 100 liters of payload instead of 30.

The payload had an Ion Mass Spectrometer to measure the composition of the atmosphere for the International Geophysical Year.

 The Negi-E sounding rocket had almost twice the diameter of the Negi-B, C, or D. This would eventually become the first stage of an orbital launch vehicle. A dedicated space agency was planned to be established in late 1962.

On 1962-10-01, the Hatsunia Aerospace Science and Development Agency was established, being spun off from the Hatsunia Science and Technology Agency. An orbital launch was planned to occur in less than two years.
