Reference excerpt

Orbiting Binary Black Hole Investigation Satellite (ORBIS) is a small space telescope still in development by Japan that will study binary black holes in the X-ray region. The ORBIS concept won the first prize at the 18th Satellite Design Contest in 2010, and of 2015 it was on preliminary design and undergoing thermal simulations by the Tokyo Metropolitan University with support from Japan Aerospace Exploration Agency (JAXA) and the Institute of Space and Astronautical Science (ISAS). The spacecraft will have a mass of about 46 kg and it features a propulsion system using 60 wt% hydrogen peroxide. Launch was aimed for 2020.

Scientific objectives Binary black holes (BBHs) are believed to be formed during the merger and growth of galaxies. Although several binary black hole candidates have been identified, they have yet to be verified by long-term observations. In order to ascertain that an object is a BBH, periodical luminosity change in X-ray wavelength must be detected. However, continuous observation of BBHs by large X-ray telescopes is difficult as such spacecraft are used by many groups and have numerous observation targets. Since microsatellites have comparatively low-cost, flexibility, and can fly more often than large spacecraft, they can conduct unique studies where risks are associated. As ORBIS is dedicated to study BBHs, it can conduct continuous observation of such bodies. The scientific goals of the microsatellite is to uncover the growth process of black holes and galaxies, and to and contribute to gravitational-wave astronomy. Some simulations have concluded that after crossing a certain distance, the energy dissipation of two approaching black holes ceases, result in them not getting closer any further. However, the merger of black holes is expected to occur during the collision of galaxies. This unsolved problem is known as the final parsec problem. By finding and studying black holes less than 1 pc apart, ORBIS aims to resolve this issue.

Worked examples

Example 1 — a first encounter with Orbiting Binary Black Hole Investigation Satellite

Start with the simplest possible case. Write down what Orbiting Binary Black Hole Investigation Satellite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Orbiting Binary Black Hole Investigation Satellite 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 Orbiting Binary Black Hole Investigation Satellite 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 Orbiting Binary Black Hole Investigation Satellite

In research: Orbiting Binary Black Hole Investigation Satellite appears in astronomy 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 Orbiting Binary Black Hole Investigation Satellite 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: Orbiting Binary Black Hole Investigation Satellite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Japanese space probes, Satellites of Japan, X-ray telescopes, so understanding it makes those chapters shorter.
In everyday life: Look for Orbiting Binary Black Hole Investigation Satellite 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.
