Space Flyer Unit

Space Flyer Unit is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Space Flyer Unit rather than just read about it. In short: The Space Flyer Unit (宇宙実験・観測フリーフライヤ, Uchū Jikken-Kansoku Free Flyer) was a spacecraft which was launched by Japan on March 18, 1995. Technical data The Space Flyer Unit was launched from Tanegashima Space Center in an H-II vehicle.

Key takeaways

Space Flyer Unit belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Space Flyer Unit to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Space Flyer Unit from memory before moving on to harder problems.

Reference excerpt

The Space Flyer Unit (宇宙実験・観測フリーフライヤ, Uchū Jikken-Kansoku Free Flyer) was a spacecraft which was launched by Japan on March 18, 1995.

Technical data

The Space Flyer Unit was launched from Tanegashima Space Center in an H-II vehicle. It carried testing materials and research data that held value to NASA. The crew of STS-72 aboard Space Shuttle Endeavour retrieved the satellite on January 20, 1996, 10 months after it was launched. The idea behind the implementation of the SFU was a joint effort by multiple major corporations and government agencies. The ones that were involved with the launch were the Institute of Space and Astronautical Science, the National Space Development Agency, and the Ministry of International Trade and Industry. After the shuttle returned the SFU from space it was transported to Japan and refurbished for display at the National Museum of Nature and Science in Tokyo.

Purpose The original purposes behind the SFU was to

Allow researchers better access to space research conditions. Give researchers a group experimental facility. Be able to reuse the SFU to save money Retrieve data

Technology A variety of systems that were operational within the SFU had never been implemented before. Equipment on board supported an infrared telescope, two-dimensional solar array, high voltage solar array, space plasma diagnosis, electric propulsion, material experimentation, gas dynamics, gradient heating chemicals, isothermal heating furnace and more. The core system that was built into the SFU contained an octagonal aluminum truss. Inside of that were eight boxes of trapezoidal shape. The SFU was connected directly to the Kagoshima Space Center.

Experimentation data

A number of various types of experiments that performed on board the SFU during its launch life cycle. Those experiments, and light data related to them are listed below.

Infrared Telescope in Space (IRTS) - The IRTS experiment was performed by the infrared telescope that was aboard the SFU. The intent was to produce important information into the history of the universe and structure of the milky way galaxy. The telescope had a super fluid helium cooling fan built into it to prevent it from overheating. 2D Array - The 2d array system was launched as a small module inside of the SFU. This experiment was deployed to show that large structures could (in fact) be built in space. HVSA - The Solar Array was a power source put into this system to head up multiple experiments. It is used to test the creation of "electricity" in the denseness of space from the use of technology only. SPDP - This was used on the SFU to test things going really fast in space. SPDP stands for (Space Plasma Diagnostic Package) and it was deployed with different sensors to check the effects of speed on the denseness of gravity. EPEX - This hardware that was built into the SFU was meant to do experiments related to fuel creation and management in space. MEX - This software was meant to review and research the effects of various types of liquid within a space environment. BIO - This test involved observing Japanese fire belly newt eggs hatch in deep space.

Worked examples

Example 1 — a first encounter with Space Flyer Unit

Start with the simplest possible case. Write down what Space Flyer Unit claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Space Flyer Unit before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Space Flyer Unit ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Space Flyer Unit

In research: Space Flyer Unit appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Space Flyer Unit in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Space Flyer Unit is common in secondary-school and first-year university syllabi. It links to neighbouring topics Satellites made by Mitsubishi Electric, Satellites of Japan, Space hardware returned to Earth intact, so understanding it makes those chapters shorter.
In everyday life: Look for Space Flyer Unit outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Space Flyer Unit in simple terms?

The Space Flyer Unit (宇宙実験・観測フリーフライヤ, Uchū Jikken-Kansoku Free Flyer) was a spacecraft which was launched by Japan on March 18, 1995. Technical data The Space Flyer Unit was launched from Tanegashima Space Center in an H-II vehicle.

Why does Space Flyer Unit matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
